EPIPHYLLUM. 197 
Type locality: Not cited. 
Distribution: Oaxaca, Mexico. 
This plant is a night-bloomer but the flowers are late in closing, sometimes remaining 
partially open as late as 9 o’clock in the morning. 
The above description is compiled from that of Salm-Dyck with reference to a plant 
at the New York Botanical Garden, received from Paris in 1909. 
It resembles E. strictum but the joints are more flexible and broader and it has some- 
what larger flowers than that species; we havea herbarium specimen identified by Schumann 
which was collected by P. Sintenis from a cultivated plant grown in Porto Rico. 
In 1911 C. Conzatti sent us from Coyula, Cuicatl4n, Oaxaca, cuttings of what we now 
take to be this species. These grew into vigorous plants 3 meters long and flowered in 
Washington in 1921 and 1922.

fessor Conzatti’s plant.

Plants 2 to 3 meters long, usually more or less flattened in the lower and older parts; joints 
short or elongated, 4 to 5 cm. broad, coarsely toothed or crenate, green; flowers opening at night, 
the slender tube 10 to 15 cm. long, reddish, bearing a few short distant scales; outer perianth- 
segments pink to yellowish; inner segments 5 to 7 cm. long, white; stamens in one series; filaments 
white; style pink to white; stigma-lobes yellow; fruit oblong, 7 to 8 cm. long, 3 cm. in diameter, 
red without, white within. 
Type locality: Near Cartago, Costa Rica. 
Distribution: Costa Rica. _ 
A species apparently composed of several races, differing in margins of the joints, in 
size of flowers, and in color of style. It is called in Costa Rica platanillo de monte.

_> Phyllocactus hookeri Salm-Dyck, Cact. Hort. Dyck. 1841. 38. 1842. 
Plants usually 2 to 3 meters long, but sometimes 7 meters long; joints 5 to 9 cm. broad, rather 
thin, light green, deeply crenate; flowers inodorous, the tube slender, 11 to 13 cm. long, greenish, 
bearing a few narrow, slightly spreading, rose-tipped scales; outer perianth-segments narrow, 
greenish pink, sometimes rose-colored at tip, the inner pure white, narrow, 5 cm. long; stamens +. 
a single series, attached at top of throat; filaments white; style carmine, except yellowish base an 
pinkish top, smooth in upper half, papillose in lower half; stigma-lobes yellow; hia green, 
somewhat angled, 2 cm. long, bearing a few small spreading scales; fruit oblong, 8 ere ong, red, 
somewhat angled, bearing a few scattered scales; seeds numerous, black, shining, reniform. 
Type locality: Cited as Brazil, presumably in error. 
Distribution: Tobago, Trinidad, and northern Venezuela. 
This plant when it first flowered in cultivation in 1826 was taken for Cactus phyllanthus 
and was so figured and described in the Botanical Magazine, but it was soon discovered 
to be very different from that species. 
While Brazil is cited as the type locality for this species we have seen no specimens 
from any point south of Venezuela. The plant is and has been widely cultivated in 
tropical America, commonly under the erroneous name, E piphyllum phyllanthus. In 
Trinidad it forms great masses on trees and on coastal cliffs, ascending the trees to a length 
of 10 meters or more, branching profusely, and is very floriferous. loubtl 
Phyllocactus marginatus Salm-Dyck (Cact. Hort. Dyck. 1844. 37. 1845) doubtless 
belongs here.
