Didymosperma is a genus of East Indian palms of moderate growth, containing possibly eight species, most of which are stemless or else forming but a short trunk, the pinnate leaves rising from a mass of coarse brownish fibers that surround the base of the plant. The leaflets are of irregular shape, bearing some resemblance to those of Caryota, and the plants frequently throw up suckers from the base. The members of this genus are not very common in cultivation. The species that is most frequently seen is the plant known to the trade as D. caryotoides, an attractive warmhouse palm that has also appeared under the synonym Harina caryotoides, and has lately been referred to Wallichia, which see. While young, at least, the didymospermas enjoy a warm house and moist atmosphere with shading from full sunshine, though one species, D. oblongifolia, (or Wallichia), is frequently found in Sikkim at an elevation of 3,000 feet above the sea. Propagated usually by seeds; occasionally by suckers, which are kept rather close for a tune after their removal from the parent plant. See G.C. II. 24:362 for description of garden forms.
