RHIPSALIS. 233 
Figure 225a shows two branches with a single fruit 1.33 times natural size; figure 225) 
shows a branch twice natural size; figure 225c shows one of the bracts which subtend the 
areoles, 4 times natural size, 
all drawn from plants ob- 
tained by Dr. Shafer from Dr. 
Lofgren in 1917 and since 
grown in the New York Bo- 
tanical Garden.

There has long been much uncertainty regarding this species and Dr. Rose, during his 
trip to South America, in 1915, endeavored to solve the problem. He first visited one of the 
three localities mentioned in the original description, namely Tijuca, a mountain near Rio 
de Janeiro. Here he found two species which belonged to the same group, Rhipsalis 
grandiflora and R. pulvinigera. He then visited the herbarium of the Museo Nacional, where 
he found specimens of R. neves-armondit. Unfortunately, they did not bear an original label 
but one doubtless written after the appearance of the description in the Flora Brasiliensis 
for the three localities mentioned therein. After studying this material carefully, he visited 
the mountain region just above Tijuca, namely Pica Popagaya, where he feels certain he has 
collected the true form, although the joints are more terete and the flowers are pure white 
instead of yellow; it is a singular Rhipsalis and a very shy bloomer. A second visit was 
then made to Tijuca, but lower down on the mountain, and here he again found this species.

locality in 1915 (No. 20673), which flowered in the New York Botanical Garden in 1916;

25. Rhipsalis pittieri sp. nov. 
Epiphytic, resembling in habit Rhipsalis cassutha; branches 5 to 6 mm. in diameter, dull green, 
terete; petals greenish yellow, 5 to 6 mm. long; ovary sunken in the stem, surrounded by white 
hairs; fruit maturing very slowly, white; seeds black. 
Collected by H. Pittier near Hacienda Koster, Borburata, near Puerto Cabello, 
Venezuela, in 1913 (No. 6467), and flowered first in Washington in the fall of 1914 (October 
16), the fruit maturing March 16, 1915. The plant has repeatedly flowered since. This
