April 2013: Whistling Ducks, Cold Waters, Rabbitfoot Grass, Arboreal Cacti, Artichokes, Monet, and More


Not a true duck, this noisy black-bellied whistling duck (Dendrocygna autumnalis) and its mate have been staying close by the Creek for most of the month.


We've had several cold mornings recently, with stern ice on the windshield and roof of the pickup this morning (April 20).  But the sunshine along the waters has been beautiful. Even if the quality of the video isn't:

Rabbitfoot Grass in Morning Light



 


One of the lessons of the Tao is that some things just should not be commented upon.  Words fail us.  And that's all I will say about a rain lily in April.

Note the small red dot on the main limb in the upper center of this image.
This fine live oak below the boulders of Whitman's Rough hosts mosses, lichens, ferns, and at least two species of cactus.

  
Under the roof of our back porch, a pair of eastern phoebes have built a nest and hatched out several young.

 And we've gotten back in the bee business.

Grass (Part One of Near-Infinity)


I loafe and invite my soul,
I lean and loafe at my ease observing a spear of summer grass.
. . .
A child said What is the grass? fetching it to me with full hands;
How could I answer the child? I do not know what it is any more than he.
. . .
I believe a leaf of grass is no less than the journey work of the stars,
And the pismire is equally perfect, and a grain of sand, and the egg
of the wren,
And the tree-toad is a chef-d'oeuvre for the highest,
And the running blackberry would adorn the parlors of heaven,
And the narrowest hinge in my hand puts to scorn all machinery,
And the cow crunching with depress'd head surpasses any statue,
And a mouse is miracle enough to stagger sextillions of infidels.

I find I incorporate gneiss, coal, long-threaded moss, fruits,
grains, esculent roots,
And am stucco'd with quadrupeds and birds all over,
And have distanced what is behind me for good reasons,
But call any thing back again when I desire it.

(a few lines from Walt Whitman's Leaves of Grass)


Remember the Rabbitfoot grass? (memory jogger below)





Well, here's another that closely resembles it.  This one is Canary grass, and as with its look-alike, it grows alongside The Creek now.


Canary Grass (Phalaris caroiniana)





And another . . .

Texas fluffgrass (Tridens texanus)

Tridens texanus


Earlier in the year we built a big brush fire and last year's growth on this specimen burnt low. But as evidenced in the first photograph, fires can be good for grasses.  

Below are some visions of a grass that most likely was an ancestor to our modern corn.  It's a tall and lovely thing called Gamma grass or Eastern gamma grass.
Later in the season this gramma grass will produce fruits that look remotely similar to corn kernals, suggesting again the close relationship between Tripsacum and Zea (corn).

As Harlin points out, we have so many grasses with the name "gramma" because, as it turns out, the word means more than an alternate spelling for grandmother.  The Latin "gramen" suggests "grass" or "grass fodder."  The Proto-Indo-European *ghros- perhaps meant "young shoot, sprout," from base *ghre- which is related to grow and green.  


To "graze" comes from the Old English grasian, "to feed on grass," from græs "grass."  And a "swath" was the "space covered by the single cut of a scythe" cutting through a meadow of grass because "meadow" itself is from the Old English mædwe, originally referring to "land covered in grass which is mown for hay,"  itself derived from the Old English heawan "to cut."  And of little relation, some have suggested that our word "fog" comes from a Norwegian word fogg, meaning “long grass in moist hollow.”  Root words.


Hay.  The gramma grasses often find themselves cut and dried like so many others for so many years.


Of course, we aren't the only species to make hay and store the harvest of grass. All kinds of rodents do it. And insects. I've read about leaf cutter ants growing fungus gardens on hoards of shredded jungle cut and stored away under ground.  A few years ago I first watched the western leafcutter bee harvest half a morning glory vine as if it were so many leafy fields suspended in air and tied round a post. The small black and gray striped. Megachili perihirta of the Megachilid Family is half an inch long and could easily be overlooked for its close resemblance to any small gray fly you've ever almost seen flying about the yard or lying dead beneath a window screen. I do not even know how long I failed even to notice the chomps taken out of the morning glory leaves and the incredibly industrious insect responsible. The bee buzzes slowly onto the leaf, sets the edge of leaf between two bee- knives disguised as mandibles, and in three seconds it has cut out an oval or a round piece of leaf the size of your iris. Then the bee folds the piece of leaf like an enchilada between its two sets of legs, three on each side. Often it then flies with its harvests to a nearby leaf, rests there for ten or fifteen seconds before buzzing back to a small space between the boards of the porch. Almost every leaf of the morning glory plant has at least one oval or round cut-out on its edge, and most of the leaves have six or seven. So in what shape does the bee stack its round bales of drying leaf, or in what manner does it ensile its crop? I never did pry the wall boards from the studs to find out.



 In all, there are about fifty species of "gramma" mostly native to North America.  American gramma, Six-weeks gramma, Needle gramma, Gypsum gramma, Purple gramma, Texas gramma, Matted gramma, Blue  gramma, Nealley gramma, Kay's  gramma, Harry  gramma, etc. 


And compare the inflorescence of the "gramma" above with that of another one down at The Creek:

A fine drawing of sedge.
     Harlin has been doing the hard work of navigating the identification keys to help us arrive at a name for the plants out at The Creek.  Here is some of his work at identifying the sedge growing in and near the water.  This is a great link to a site that provides about as much detail as one could hope for:    http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242357940.

Sedge (genus Schoenoplectus?)

     And a couple intimate views within the inflorescence of this sedge:
     




     And here's one of our favorite grasses . . .


Rabbitfoot Grass (Polypogon monspeliensis )
Floret of the Rabbit-foot Grass

     We've been admiring this grass within the riparian zone for a number of weeks now.  Turns out, it's not a native at all, but comes from Europe where the English call it "beardgrass."  In these United States, it grows as an annual mostly across the western half of the Union and nearly always around water.
     It's hard to imagine a more beautiful plant--especially in its juxtaposition to the many whitened stones around which it grows in thick bunches.
     And the white stones.  It would be nice to be able to say more about them because they represent something we see so much of in nature that we are tempted not to question them.  The white-covered stones of dry stream beds are like the assumptions of our prejudices.  But they can be studied and named like just about anything else.
     In our case, the white is probably the dried remains of diatoms and other algae.  In the water, the diatoms lay down a snotty film over submerged rocks and detritus.  And if floating on the surface, they form thick white, gray, or brown clumps of gelatinous snot.  The cell walls of diatoms contain high quantities of silica (silicon dioxide), the stuff of sand and quartz that is used to make glass.  So the expression "glass house" really does have an antecedent in nature.  Bits of chlorophyll color parts of each diatom with green or golden yellow.
     With over 100,000 species of diatom, we won't be too cocksure with our correct identification of any one of them, but we can locate some fairly common examples.  Here's a photographic sampling of some fresh-water diatoms found in The Creek and Wikipedia:

Another really sorry photograph of two young and lovely olive trees (Mission and Arbequina)
that we hope to plant out at The Creek following next winter. Just for the record.
