Tamarisk: origin of "salt cedar"
"P van Rijckevorsel" wrote in message . ..
Mike Lyle schreef As AUE regulars may know, but sci.bio.botany readers may not, I like tracing the history of our words; and have a healthy suspicion of what may seem obvious origins. "Saltcedar", for example, seems a quite obvious name given the American tendency to use "cedar" rather promiscuously and the genus's well-known tolerance of saline conditions; but there are plenty of English words and expressions which superficially look as "logical", but which turn out on investigation to have quite different origins. I wanted to be sure. + + + Common names are quite tricky. I have only limited faith in dictionaries, although obviously they are great for a quick approximation. + + + Hell of a lot more reliable than people, though! But what they *can* tell you is when a name was first published. Even the name *Tamarix gallica* once had an alternative *Tamarix anglica*, though I think the species hails from SW Europe. + + + This is not the right way to put it. Tamarix anglica is among the synonyms of Tamarix gallica. The exact relationship between these two names may require some work to dig out. + + + Really? I thought it was plain obsolete, having been based on horticultural practice alone. But I'm not quite convinced that the specimens available in commerce are always correctly named, anyhow. And *Tamarix germanica* is listed by Hillier as *Myricaria germanica*, first known to have been cultivated in Britain in 1582. + + + Apparently the family has four (five) genera of which Myricaria is one + + + The two true tamarisks most common in British Isles gardens are *pentandra*, flowering in August, + + + According to the Hillier you refer to (1998 edition) it now is called T.ramosissima (introduced c 1885) + + + Thanks again: my Hillier is from 1974, and lists *ramosissima* (*odessana*) separately from *pentandra*. It's easy to get left far astern! The '74 descriptions and regions of origin are close enough to make it easy to see that they were very likely to be the same sp. The online RHS Plant Finder kindly displays *ramosissima* automatically if you enter *pentandra*. and *tetrandra*, flowering in May, and don't appear on the face of it to have been cultivated in Br before the 19C. But *gallica* is naturalized on some English coasts -- though not, perhaps, as destructively as in some US zones. I think work needs to be done on the precise ancestry of British specimens; and I'd like to know when the various species first arrived in the US. + + + Good luck to you. Seems you have your work cut out for you! + + + I'll leave the family tree to some hungry graduate student. I'll stick to the published literature! (AUE knows me as a word-hack; but with another hat on I've just done an estuarine garden in which I wanted to include both the common species, to give a longer flowering season. Material wasn't available in the limited time I had, so *tetrandra* it was.) Mike. + + + On a practical note I was interested in seeing that the family is now judged to belong to Caryophyllales, which is quite fitting considering the sort of habitats it prefers. PvR Thanks again: that does make sense. Till the next reclassification. Mike. |
