Wallichia (Nathaniel Wallich, 1786-1854, Danish botanist; wrote on plants of India). Palmaceae. Stove palms, one of which, the first described below, is cultivated outdoors in southern Florida and southern California and in Europe under glass, and the second, while not advertised in America, is probably in a few northern greenhouses. Low palms, cespitose, with short branching caudices, or in 1 species tall: lvs. densely fasciculate, terminal, distichous, scaly, unequally pinnatisect; segms. solitary or the lowest in groups, cuneate at the base, oblong-obovate or oblanceolate, erose-dentate, the terminal one cuneate; midnerve distinct; nerves flabellate; margins recurved at the base; petiole slender, laterally compressed; sheath short, split, with the margins deeply crenate: spadices short-peduncled, the staminate drooping or recurved, ovoid, much branched, densely fld., the pistillate looser, erect; spathes very numerous, slender-coriaceous, the lower ones the narrower, tubular, the upper ones cymbiform, entire, imbricated: fls. symmetrical, the pistillate much smaller than the staminate, yellow: fr. ovoid-oblong, red or purple.—Three species, Himalayas. Wallichia is allied to Didymosperma, Arenga, and Caryota, differing in having 6 stamens instead of an indefinite number. Caryota is the only one of this group with ruminate albumen. Didymosperma has a cup-shaped 3-lobed calyx, and in Arenga the calyx has 3 distinct sepals. W. densiflora, Mart., a palm like W. caryotoides and differing only in technical ovary characters, is offered in Eu. Unknown in Amer. J.F. 3, pls. 233, 234. — W. porphyrocarpa, Mart.
