TyPE LocaLity: Mexico. 
Disrripution: Mexico. 
ILLUSTRATION: Schum. loc. cit. /. 76. 
The plant in the New York collection looks a little like a small Cephalocereus, and 
Schumann’s figure is not against this view. 
Cereus longicaudatus Weber; (Gosselin, Bull. Mus. Paris 10: 384. 1904; 
TYPE LocALity: Near Mesquititlan, Mexico. 
Flowers and fruit undescribed. 
This species is undoubtedly the same as Cereus rayans Brandegee. Both were 
published in 1904.

Type Locauity: ‘ Mountain sides, south of Moleje, Lower California.”

This is probably an Echinocereus.

TYPE LOCALITY: Mexico. 
DistripuTion: Southern Mexico. 
Intustrations: Bot. Mag. 66: pl. 3768; Berger, Ann. Rep. Mo. Bot. Gard. 16:

We agree with Mr. Berger in excluding this from Aporocactus, but we do not 
know its fruit.

Cactus paniculatus Lam. Eneyel. 1: 540. 1783.

Cactus repandus L. Sp. RJ. 467. 1753. 
Tyre Locatrry: Curacao [South America] (according to L. Hort. Cliff. ). 
From description clearly a Cephalocereus. Willdenow @ refers to this a Jamaica 
species, which is doubtfully correct. The plant taken by Schumann as C. repandus 
is Harrisia. U
