The species illustrated by Cavanilles is a South American one and was doubtless wrongly attributed to Mexico.
SiPHOCAMPYLUS GLANDULOSUS Lemairc, Herb. G6n. Amat. II. 3: pi. 56. 1843. This species is identical with Siphocampylus rugosus Lemaire, the name having been changed because of the earlier 5. rugosus (PresI) A. DC.
SiPHOCAMPYi^us RUGOSUS Lemaire, Hortic. Univ. 3: 311. 1842. Type localitv'; Described from a cultivated plant said to have been introduced from Mexico. The plate published by Lemaire (see Hortic. Univ. 3: 369-372. 1842) indicates that the species is probably to be referred to Siphocampylus reliculalus (Willd.) Klotzsch & Karst.; Vatke, a native of Venezuela.
