Thanks for rehashing your creationist version of intro to botany class for
us, Bae, but we have already heard it before. Although we know you are just having fun, Welwitschia is indeed a tree in the botanical sense of the word. Have you ever seen one in your reality? They don't grow wild in Toronto. If your socks have holes in them, it would be a good idea you make the effort to go and buy a new pair to cover your really smelly feet. wrote in message . .. In article , Iris Cohen wrote: What about pawpaw (_Carica papaya_) "trees" which are really very large herbs? Pawpaw is Asimina triloba, a member of the Annonaceae, definitely a tree. Carica papaya, the papaya, is referred to as a plant, not a tree, same as a banana plant. In the US, Carica papaya is called papaya, and Asimina triloba is called pawpaw, or papaw, which is a corruption of the Spanish word papaya, meaning the fruit of C.papaya, derived from its name in a Cariban language. In Australia and some other parts of the English speaking world, C.papaya is called pawpaw, and A.triloba is unknown. In a more general sense, the same applies to the English word "tree", which is not really a botanical term. Comparable words in other languages, especially non-Indo-European languages, won't refer to quite the same set of plants. The real world is a messy place with fuzzy edges. Plants just grow and evolve, and are not concerned with what they are called in English. We try to shove them in labelled boxes but there's always a few toes of socks and other odds and ends sticking out because we're imposing an artificial distinction on reality. So-called trees have evolved in many unrelated taxa. It's a term of convenience for us. The genus Ficus, for example, has trees, shrubs, vines and creepers in it. Lots of temperate climate plants grow as shrubs or trees. A coppiced tree may grow back as technically a bush, multitrunked, even if it gets 20 meters tall. The wood of a pine, though a gymnosperm, looks a lot more like the wood of an oak (angiosperm) than oak wood looks like the spongy fibrous stuff that makes up the trunk of the angiosperm palm tree. Bamboo is better wood than palm trunks, and can grow as tall, but it's a mere grass, even if it is much more useful as timber. Arguing whether Weltwitschia is a tree is fun, but it's playing with words, not botanical reality. |
