Selenicereus maxonii Rose, sp. noy. 
Stems light green, but often becoming deep purple throughout, often 3 em. in 
diameter; ribs 5 or 6, rather prominent but less so on the older branches; areoles 
small, white; spines short, yellowish; reflexed bristles or hairs from the lower 
part of the areoles several, white, longer than the spines; flowers noeturnal, 20 em. 
long; sepals and bracts linear, greenish or brownish, sometimes nearly rose-colored; 
petals white, rather broad; stamens numerous; style cream-colored, stout; tube 
proper about 10 cm. long, bearing scattered short, linear bracts, the axils bearing 
short white wool and long silky white hairs and white bristles; ovary similarly 
clothed but with the bracts more closely set. This species has flowered twice in 
cultivation (April and May, 1909).
