This plant may undoubtedly be confidered as the mofl: beautiful 



•of the whole genus. The elegant form, the waved margins, and 



delicate veining of the leaves will readily diftinguifh it from all its 



congeners. The fubftance of the ftem is cartilaginous, that of the 



leaves membranaceous, extremely thin and tender ; the whole is 



generally diaphanous, though in a very advanced ftate the ftem is 



fometimes opake. It frequently is only fimply branched; the ftem 



is then very fliort, and bears a few leaves, each fupported on afhort 



footftalk: others are very much branched, but in thefe the feparate 



branches foon terminate, and form footftalks to the leaves : in the 



former ftate it is well reprefented by Gmclin, and in the latter is 



vciy well figured in Fl. Dan. The leaves vary from three or four 



inches to a foot in length, and from half an inch to two or more in 



breadth. The footftalk is nearly round, but is continued through 



th6 leaf, where it is comprefled, and forms a ftrong midrib, which 



is pinnated with others >very flender, and either fimple or branched 



at the bafe. Thefe are fometimes alternate, but more frequently 



oppofite, as reprefented in Fl. Dan. though they are very rarely fo 



confpicuous, or fo much brancTied as in that figure. Sometimes 



ithe leaf becomes proliferous, a footftalk arifing from the midrib, 



and
