188 THE CACTACEAE. 
The species has been recorded from the West Indies, apparently erroneously. 
. Our description is based on field notes made by Dr. Rose in Brazil in 1915 which differ 
slightly from published descriptions. This plant is common in the woods along the coast of 
eastern Brazil, often growing in inaccessible places high up in the great trees. Open flowers 
were not seen, but buds, fruit, and seeds were obtained. Living 
plants were collected and these have done well; one flower appeared 
in the collection of the Department of Agriculture during Dr. Rose’s 
absence in Ecuador in 1918. The caretaker, Mr. Fraile, describes the 
flower as long and slender and very unlike other species of Epiphyllum, 
of which he has seen many (Rose, No. 19627). It fruited in the New 
York Botanical Garden in 1920. The plant is called flor de baile or 
flower of the ball. 
An Epiphyllum grows in the lowlands of Ecuador which we have 
tentatively referred here, although we have never seen its flowers or 
fruits. Dr. Rose collected it below Huigra, September 8, 1918 (No. 
22614), and again above Santa Rosa near Limén Playo, October 17 
(No. 23493). 
Cactus phyllanthus of Linnaeus (Sp. Pl. 469. 1753) and Epiphyllum, 
phyllanthus Haworth (Syn. Pl. Suce. 197. 1812) both contain references 
not only to this species but to Epiphyllum phyllanthoides also. 
The variety columbiensis was described by both Weber and Schu- 
mann with a flower-tube only 6 cm. long. Fic. 195.—Seedling of 
Cereus phyllanthus marginatus Parmentier is mentioned by Lemaire . Epiphylium phylian- 
(Cact. Gen. Nov. Sp. 76. 1839) but not described. -

by Dr. Rose in Brazil in 1915; figure 195 shows a seedling with its two large cotyledons, 
grown from seeds sent by Mrs. D. D. Gaillard from Panama.

Plants stout, 3 meters long or more, much branched; branches flat and thin, 10 to 12 cm. 
broad, long-acuminate, deeply crenate; flowers opening in the evening, drooping and limp after 
anthesis, fragrant; tube of flower 13 to 15 cm. long, rather stout, red, about 1 cm. thick, bearing 
distant narrow scales about 10 mm. long; outer perianth-segments narrow, reddish to amber, 8 to 
10 cm. long; inner perianth-segments oblong, white; stamens numerous, white; style white, thick, 
20 cm. long; stigma-lobes numerous, cream-colored, entire. 
Type locality: Mexico. 
Distribution: Mexico and Guatemala, Venezuela, and Brazil. Widely cultivated in 
the tropics and doubtless an escape in many places.
