Acanthorhiza (Greek for thorn, and rhiza, root). Palmaceae, tribe Corypheae. A genus of tropical American medium-sized palms.

Leaves crowded at the end of the trunk, palmate, 3 to many, divided to the base, but the Begins, stalkless, and in age becoming typically 3-4 divided, the segms. then wedge-shaped; lf.-stalk flattened very persistent, slender and smooth, the sheath short and fibrous; as the lvs. unfold the margins are bent inward the external faces applied together: infl. flattened at first, the short peduncle and thickening branches white, bracteate, the bracts diminishing downward; fls. cream-white, in spike-like, dense clusters, these racemose; stamens quite free, differing from Trithrinax where they are united to form a tube. It has never been known to fruit in cult.—Three or four species onlv are known, all from Trop. Amer., but not so well known to the trade as their great beauty and stately dimensions deserve. G.C. II. 22:426.

These palms have spineless trunks, except at the base, where the aerial roots subsequently harden into stiff downward-pointing spines; differing in this from Trithrinax, the nearest relative.

They should be grown as stove palms, a night temperature not less than 60° being preferable. If possible plant put the tall plants, as they do much better when not disturbed by subsequent repotting. A good mixture should contain good, fibrous loam and considerable sand.

Propagation is only by seeds, sown preferably in the spring, in fresh peat over bottom heat.
