The following are trade names of rare or botanically little-known plants not sufficiently described: C. Alphonsei. - C. Arechavalelina, Barb., is described as somewhat like C. Romanzoffiana but taller and making larger crowns. It is a native of Uruguay. - C. Blumen-avi=C eriospatha. - C. Bonnetii. - C. Gaertneri=(?). - C. Gerita, Hort. G.C. III. 27:293 figures C. Geriva, a remarkable Cocos (?) with 4 branches. Nothing further is known of this plant. It may be C. Geriba, Rodr.=C. botryophora, Mart. - C. Maximiliana, Hort.=(?). - C. odorata, Rodr. stem short: leaflets in 3's or 5's, linear-lanceolate; petioles spiny: fruit yellowish green or pink, pulp scented. Brazil. R.H. 1893, p. 345. - C. pulposa, is supposed to be very like C. eriospatha. This species is scarcely known in this country. -C. Yurumajnas=(?). N.Taylor.†
