Hydrangea 2007

Hydrangea 2007, an international conference (http://www.hydrangea2007.be/en.php) devoted to hydrangeas for enthusiasts and gardeners, is approaching, and I’m speaking.   The conference, which will be held at the Ghent University Botanical Garden in Belgium, begins on 16 August.  And on Friday, I began work on my talk.  This involved perhaps an hour of pacing, and then I fixed tea, and then I made a trip to a vending machine for some chips.  With tea and chips, I settled into writing.

I typed my title—‘Becoming Hydrangea’—and went on to the senses that I want the audience to take from it. The first is an evolutionary sense—I want to convey the changes that occurred in Hydrangeaceae, the hydrangea family, to give rise to the plants that we recognize as hydrangeas. The hydrangea family includes several genera in addition to Hydrangea, and many of these would not be popularly recognized as cousins of Hydrangea.  The second sense of ‘becoming Hydrangea’ is taxonomic. Our studies to reconstruct the evolutionary history of the hydrangea family have shown that Hydrangea in an evolutionary sense is broader than what Hydrangea has been in recent taxonomies.  If we are to understand the diversity of hydrangeas, we need to change our taxonomy to reflect better our understanding of evolution in the Hydrangea lineage.

On Friday, I wrote those introductory ideas, explaining our knowledge of the evolutionary history of the family, how it is most closely related to Loasaceae, another family of research emphasis in my lab, and more deeply related to dogwoods, tupelo, and the dovetree.  I sketched notes on the timing of the evolutionary split between Loasaceae and the hydrangea family and described the geographic radiation that occurred within Hydrangeaceae.

After cleaning the bathroom, getting groceries, and starting a load of laundry, I went today to the writing table in the basement as the afternoon heat began to rise in my house.  There I wrote about the ecological and morphological changes that mark the lineage that would become Hydrangea and also began to write about the broadened sense that we need for the genus. 

Finally, the lineages of Hydrangea came up; I began to think about the important points that I would like to make about the diversity we find in Hydrangea.  And I began wonder where I’ve stored all of the images I’ve used over the last decade in talks about the evolution of hydrangeas.  This is a topic I haven’t addressed in detail for a few years, and I hesitate to think about the out-of-date storage devices on which all of my electronic files have been stored. 

Tomorrow morning, first thing, I must look for the cache of electronic images as well as the hoard of negatives and slides that I will need to make new images for the talk.

Henry Dies

Thoreaugrave_low_res

I thought that Ralph Waldo Emerson would write about Henry Thoreau’s death.  I expected Emerson to make some note of his feelings or describe what he had done after hearing of Henry’s death, but there is no note of Thoreau’s death in Emerson’s journals.  Emerson and Henry had been wearyingly close.  Thoreau had lived in Emerson’s house for extended periods on at least two occasions.  For even longer, Thoreau had been a handy fixit-man and firewood cutter for Emerson. 

Emerson knew Thoreau’s death was coming.  In January 1862, Emerson wrote the header “Old Age” in his GL journal.  “As we live longer,” Emerson wrote, “it looks as if our company were picked out to die first, & we live on in a lessening minority.”  Emerson listed friends in England and Rome who had died.  Here, Emerson noted, Mary Howell Russell, a friend of his wife Lidian, had died, and he jotted also “I am ever threatened by the decays of Henry T.”

On the first of April 1862, when Thoreau lay immobile, dying, in bed, Emerson went to Walden Pond, where he walked across the ice.  The next day he wrote in his journal, “I walked across it again.  I fancied it was late in the season to do thus; but Mr. Thoreau told me, this afternoon, that he has known the ice to hold to the 18th April.”   Henry’s mind remains like the ice, but his body is melting. 

Emerson noted later that the ice remained unbroken on 18 April despite the warmth of the day, and Mr. Channing, he noted, had been on the ice the day before.

May 6, 1862, went without remark in Emerson’s journal.  It was later in the month that he wrote the header:
“Books bequeathed to me
by Henry D. Thoreau.”
The books were mostly Hindu religious myths and other writings on eastern art and philosophy.  Thoreau had introduced Emerson to Asian myths.

Through June and July, Emerson read Thoreau’s journals.  “Henry T. remains erect, calm, self-subsistent, before me, and I read him not only truly in his Journal, but he is not long out of mind when I walk, and, as today, row upon the pond.  He chose wisely no doubt for himself to be the bachelor of thought & nature that he was,—how near to the old monks in their ascetic religion.”

Emerson began to quote from and comment on Thoreau’s journal.  “He loved the sweet fragrance of Melilot,” Emerson recalled and then, in response to a description of Henry’s, “He is very sensible of the odor of waterlilies.”

Nathaniel Hawthorne was living in Concord when Henry died, and he also failed to mention the death in his journals.  Hawthorne had noted well the living Thoreau.  As Hawthorne planned his move to Concord, which had been encouraged by Emerson, Thoreau had planted a garden for Hawthorne and his new wife—Emerson had hired Henry to do the gardening.  Hawthorne would rent a house that had been in Emerson’s family, a house that Hawthorne would call the “Old Manse” in stories that would add to his fame.  Within days of Hawthorne’s arrival at the Old Manse, he tells us in his journal:

“Mr. Thoreau dined with us yesterday.  He is a singular character—a young man with much of the wild original nature still remaining in him; and so far as he is sophisticated, it is in a way and method of his own.”

Only a few months later, in the spring, Thoreau told Hawthorne that he was leaving Concord—Henry had been living in Emerson’s house and Hawthorne noted that “Emerson appears to have suffered some inconveniency from his experience of Mr. Thoreau.”  Hawthorne wrote, “On my account, I should like to have him remain here; he being one of the few persons, I think, with whom to hold intercourse is like hearing the wind among the boughs of a forest-tree; and, with all this wild freedom, there is high and classic cultivation in him too.”

Ellery Channing began in the days after Henry’s death to write his biography.  On the day that Henry died, Channing went to the Alcotts’ home to tell them the news.  Like Channing, Bronson Alcott had been deeply affected by Henry, and, hearing of Henry’s death, Alcott walked to the Thoreau house to kiss the forehead of his beloved friend.

Louisa May Alcott, who had attached to Henry a young girl’s romantic fantasies, wrote about Thoreau’s death.  “On Tuesday at eight in the morning he asked to be lifted, tried to help do it but was too weak and lying down again passed quietly and painlessly out of the old world into the new,” Alcott wrote to Sophia Foord, who had also admired Henry.  Louisa Alcott was displeased that Emerson had disavowed Henry’s wish not to have a church service at his death.  “Emerson,” Louisa wrote, “ said his sorrow was so great he wanted all the world to mourn with him.”  She disliked the address that Emerson read at the funeral.  In Louisa’s mind, Henry might have belonged to her.  “It was a lovely day, clear, and calm, and springlike,” she wrote to Foord, “and as we all walked after Henry’s coffin with its pall of flowers, carried by six of his townsmen who had grown up with him, it seemed as if Nature wore her most benignant aspect to welcome her dutiful and loving son to his long sleep in her arms."

It was 6 May 1862 when Henry died.

Course planning

At 4.30 this morning, I woke sharply and tensely.  The needs of my fall semester course reeled through my mind.  Classes start in a month.

I’ll teach this fall introduction to botany.  It’s a course that serves our general education curriculum, which means that it can be taken by anyone, regardless of his or her science coursework background, to fulfill university science requirements.  About half of the students who enroll have never had a biology course, and many these students are apprehensive, if not fearful, about science.  It’s an opportunity to talk genially about material I thoroughly enjoy and to indulge in metaphors and stories to teach a few basic ideas about plants.

I plan to revise completely my lectures and with a colleague, with whom I alternate teaching the course every other year, I am revising the laboratories.  The old laboratory manual hasn’t been working well for the students.   We will create new laboratory exercises that emphasize investigation and experimentation.  And I will prepare new lectures centered on about dozen concepts, and, of course, I’ll prepare the lectures in Powerpoint. 

A year ago, I revised my plant diversity course to apply Powerpoint.  Each of the 75-minute lectures for that course took about 18 hours to prepare.  My three lectures per week this coming fall semester will each be 50 minutes, requiring, I expect, about 12 hours of preparation per lecture.  That 12 hours of preparation, although difficult to think about in the middle of the summer, has been typical for all of the new lectures I’ve prepared for courses over the years.

With tea and toasted bagel at hand this morning at 5.00 a.m., I was drafting notes for laboratories.  For a couple of laboratories, I wrote first the concepts to address and then sketched out possible exercises and materials we could use.

I walked to campus about 8.00 and pulled-out my lectures and syllabus from the last time I taught the course.  Although I’m scheduled to teach this course every other year, because of the timing of my recent sabbatical leave, I last taught it four years ago.  As I sorted through the old lectures, I wondered what could be scavenged to fit the new objectives and format for the course.  I wondered also how to sequence of course concepts and how they would fit with the laboratories.

I turned-on my computer, opened Word, and listed my lecture dates.  I blocked-out the concepts, largely giving one concept to each of the fifteen weeks of the semester, and tried to fit laboratory topics as closely as possible to the lecture material.  It’s all so simple, so natural.  Then I revised everything, adjusting the sequence, dividing a few themes, and I added some material on plant conservation and flora of the Pacific Northwest that I haven’t used before.  I began to admire the schedule and held it at arm’s reach to get a good look – that’s when I recognized that no exams had been scheduled.  I added the tests.

At the end of the afternoon, I typed ‘Syllabus’ in bold at the head of the lecture schedule.  All I need to do now is write the lectures and laboratories.

Dinner

As I came into the mountains along the North Fork of the Clearwater River, I saw movement on a rock beside the water.  Using binoculars through the windshield, I could see that it was a large bird.  I continued up the road in the truck, stopping nearly opposite the bird to look through the space of the lowered side window.   It was an Osprey on a broad, flat-topped boulder that angled to the river.   The Osprey was perched on a cutthroat trout.  The bird and the now headless fish were nearly the same length.  The stone had splatters of blood and bits of meat, and a pink stripe extended down the boulder from the fish’s tail. I imagine the Osprey let the fish hit hard on the stone and then dragged it a few inches to a more suitable spot for dinner.  The Osprey stood watchful for a few moments after I arrived and then went back to its dinner. It would tilt its head down and twist it to the pink meat of the fish’s shoulders. The bird tugged and then lifted its head; its beak was full of pink fish.  Sun shined on the yellow flank of the fish.

I camped along the river, setting up my canvas chair to face the water a few miles beyond the Osprey. For dinner, I had Bombay potatoes with chickpeas and an orange with a cold, Belgian-inspired ale. My plant press served as a table, and I leaned from my low seat to the bowl of spicy potatoes and chickpeas. I sopped the brown gravy with a multigrain bagel, and a few brown drops fell on the plant press.  After dinner, I heated water for tea on my backpacking stove, which sat in the sand at arm’s reach from the chair. Kingfishers flying from mid river stones to low, shoreline branches made blue flashes.

Wasps

When I stepped from the back door a couple of days ago, my head was swarmed. While I should have just moved quickly onward, I didn’t - I waved my arms, trying to sweep the swarm away.  The swarm pressed into my hair and tightened against me.  Luckily, I was stung only once – the lobe of my right ear was pierced.  It was wasps.

After I escaped the swarm I looked back to see that the wasps had constructed a nest on the bottom of my deck.  The nest hung just two feet beyond and above the back door.  It was an inopportune location for a bunch of anxious wasps as well as for me, the anxious home-owner who regularly walked below the nest.

Last night after the wasps were asleep, I sprayed their nest.  I had purchased a can of wasp killer when I went to the grocery for a New York Times yesterday.  I hated to destroy them.   The nest was beautiful, a symmetrical, gray cone – if only they had built somewhere more distant from my door and my head.  When I lifted the aerosol can toward the nest, I had expected a light spray; instead, it emerged with the force of a garden hose, recoiling my arm and blasting the nest.  I backed-off to spray more.  Two wasps zipped from the nest entrance, and I backed through the door.  This morning I found a cluster of dead wasps, suspended together, hung from the opening of the nest.  A horror.  I have been their Hurricane Katrina.  Forces of nature make us suffer our building choices.
