At what hour the Creek ceased to flow is not known. Maybe creeks are special about not having a moment of death capable of being witnessed by us.
A couple small pools and the main pool still have water and fish, but the flow has gone out of the stream, and with the loss of flow, so also the loss of a sound and a shine.
Up along the row of blackberry vines on the unnaturally thriving snow-on-the-mountain plant we've been looking at for several blog posts, I found this beautiful wasp-look-alike insect that may be a robber fly (Lampria bicolor). If you can correct this identification, please let us know.
And here we have an exploration of cinematography for the patient stone-watcher inside each of us. I stone-watched on the west side of the Un-Creek.

Harlin sent the following photographs and notes a few days ago.
We are in the realm of easily misidentified with these two plants, not to mention the non-spectacular. Still, they are different from the other plants which have been added to the Hamilton Creek plant list previously and that in itself is progress. HH

These two [below] are not only more colorful than the last two plants, but they have distinctive characters that rule out a large number of wrong possibilities. These characteristics are not guarantees, but finding something that seems to be rare is an enjoyable experience at the end of the find-a-name puzzle. In the example of the bean family vine Strophostyles, the unusual shape is that thing in the middle of the flower. I have a book about the legumes of Texas and the description for the genus Strophostyles says "keel strongly incurved." My picture looks similar to

The name "heterotheca" means something like "different cases" since the achenes for the ray flowers don't have the pappus of bristles and the disk flowers do have achenes with the bristly hair on top (along with some other differences).
I've found that it is good to take a few non-pretty pictures along with the pictures that might look good. In fact, I usually feel I should have taken more of them. They help answer questions that my sometimes rushed preservation hasn't preserved. I mention that since in this case I also wish I had taken better pictures of the wild bean's keel and looked for good examples of the camphor weed's two kinds of seeds. Of course, I didn't even know what I was missing at the time. HH

And here's something interesting on the wild bean:
Wild bean (trailing wild bean) Fabaceae [Steyermark: Leguminosae, Popilionoideae] Strophostyles seeds are generally found in sieve sizes greater than 2.0 mm. Occasionally, pods are found as well (see Fritz 1986). Strophostyles helvola is found in archaeobotanical samples from sites of both foraging and agricultural groups. Description The modern seeds are oblong with square ends, 5-10 mm long and 2-3 mm wide, with a grayish brown scurfy outer coat (Figure 1). The linear marginal hilum is covered with white and bordered by a narrow black outline. The pods are 4-9 cm long (Figure 2). Strophostyles helvola is easily identified archaeologically due to its long, diagnostic hilum. It is also longer and narrower than other legumes. Smaller fragments of bean make identification more difficult because they can be easily confused with other legumes, including Phaseolus vulgaris L. and Phaseolus polystachios L. Archaeological Distribution Strophostyles helvola is found from the Middle Archaic through historic times in the Eastern Woodlands. Archaeological wild bean has been recovered in Alabama,Oklahoma, the Arkansas Ozarks, and Illinois. It has been consistently recovered in the American Bottom area, generally in low numbers (Johannessen 1984). The Modern Plant and Its Distribution There are three species: Strophostyles umbellata (Muhlenb. ex. Willd.) Britton,Strophostyles leiosperma (Torry & A. Gray) Piper, and Strophostyles helvola.Strophostyles helvola is a herbaceous annual vine found in a variety of habitats, including beaches, thickets, open woods, open areas and old fields. Smith (1992:261) records finding wild bean in association with Chenopodium berlandieri which is not surprising given Chenopodium's need for nitrogen rich soil. Fritz also finds this association archaeologically in the Ozarks (1986). Strophostyles’ modern distribution is wider than its archaeological distribution. It is found from Quebec to Minnesota,South Dakota and Colorado, and south from Florida to Texas. Beans are available in the late summer and early autumn months. Discussion Although some archaeological occurrences of wild bean could be the result of natural seed dispersion, as it does grow in disturbed soils, "...it has been recorded in frequencies great enough that one can conclude with near certainty that it was used as a food" (Asch and Asch 1985:387). Wild bean is smaller than common bean (Phaseolus vulgaris), but it has similar nutritional value. "Furthermore, because it is substantially larger than indigenous starchy seed cultigens, it may have had subsistence value greater than its numbers would indicate" (Parker 1991:314). Wild beans were probably prepared in many of the same ways as cultivated beans. Although they could be eaten green, they were often dried. Ethnohistorically, the roots were boiled and mashed and used for food as well (Yanovsky 1936:38). The Houma used Strophostyles helvola as a disease remedy, with a decoction of bean being taken for typhoid. The Iroquois used it as a dermatological aid, with the leaves being rubbed on parts affected by poison ivy or warts (Moerman 1986).   |
