Fig. 200. — Epiphyllum macropterum. 



Type locality: Near Cartago, Costa Rica. 



Distribution: Known only from the type locaUty. 



Our description is based on that of M. Weber. The very scaly fruit should be charac- 

 teristic, but plants received from Costa Rica under the name Phyllocactus lepidocarpus 

 produced smooth fruits at the New York Botanical Garden. 



11. Epiphyllum pittieri (Weber) Britton and Rose, Contr. U. S. Nat. Herb. 16: 258. 1913. 

 Phyllocactus pittieri Weber, Diet. Hort. Bois 957. 1898. 

 Stem usually terete below, much divided, 2 to 3 meters long; branches flat and thin, mostly 

 5 cm. wide or less, the margins coarsely toothed; flowers rather small, the tube about 8 cm. long, 

 white to greenish white, bearing a few red, ascending scales; outer perianth-segments 4 to 4.5 cm. 

 long, narrow, yellowish green, or some of the lower ones tinged with red, acute; inner perianth-
