Slender, erect, 2 to 3 meters high; branches widely divergent, light green, 3 to 4 cm. thick, 

 9 to ii-ribbed, the ribs rounded; areoles 2 to 2.5 cm. apart; spines only 3 to 6, gray, the longer ones 

 15 mm. long; bud narrowly pbovoid, obtuse, very short-pointed, its scales subtending many curled 

 white hairs 6 mm. long or less; flower 1.6 to 2 dm. long; scales of the flower-tube linear, acununate, 

 1.5 cm. long, subtending a few hairs; fruit ellipsoid, 6 to 8 cm. long, 4 to 5 cm. thick, very strongly 

 tubercled, at least when immature, the conic tubercles 6 to 8 mm. high.

Here perhaps is to be referred Cactus fimbriatus Lamarck (Encycl. 1:539. 1783; 

 Cereus fimbriatus De Candolle, Prodr. 3:464. 1828; Pilocer ens fimbriatus Lemaire, Rev. 

 Hort. 1862:427. 1862) and (7^r^W5 5^rrw/i/Z(?m5 Haworth (Phil. Mag. 7: 113. 1830), both of 

 which were based on Burmann's plate of Plumier (pi. 195, f. i, A, B, C, and D), found along 

 the coast of Haiti under the name of la bande du sud. Cactus fimbriatus Descourtilz (Fl. 

 Med. Antill, ed. 2. 6: 160. pi. 419), which refers to the same plate of Plumier, is really 

 based upon pi. 195, f. 2, of Burmann, and is probably a Lemaireocereus.
