Eccremocactus bradei Britt. & Rose, sp. nov. PLATE 83. 
Joints 15 to 30 cm. long, 5 to 10 cm. broad, light dull green, flat, but the central 
axis somewhat elevated on both sides, the margins shallowly crenate, with small spine- 
bearing areoles in the sinuses; spines solitary or in twos or threes, dark brown, 6 mm. 
long or less; flowers about 5 cm. long; outer perianth segments pale yellow, the inner 
white, the tube nearly as long as the limb; fruit juicy, 2.5 to 4 cm. long, somewhat 
5-ribbed, the ribs undulate; seeds 1.5 mm. long. 
Type in the herbarium of the New York Botanical Garden, from a plant collected 
near Santo Domingo, Turruvares, Costa Rica, altitude 200 meters, by Brade in 1905 
and brought from Costa Rica to the New York Botanical Garden by Mr. William R. 
Maxon in 1906 (Maron 21). The plant flowered at the New York Botanical Garden in 
June and October, 1911. 
The flowers of this plant resemble in form those of Weberocereus; its joints resemble 
those of some species of Epiphyllum.
