RHIPSALIS. 235 
This species is common in northern Argentina, where it was repeatedly collected by 
Dr. Shafer in 1917. 
Of this relationship, but perhaps specifically distinct, is the plant sent by M. Bang (No. 
2323) from Coripati, Yungas, Bolivia, distributed as Rhipsalis salicornioides. Here we have 
tentatively referred K. Fiebrig’s plant (No. 5801) from the Upper Parana, Paraguay. 
Of plate xxvu, figures 4 and 5 show flowering and fruiting branches from Dr. Shafer's 
€ollection from Calilegua, Argentina (Nos. 55 and 68), painted at the New York Botanical 
Garden, May 24, 1922.

Stems 3 to 6 mm. thick, yellowish green, with dichotomous or trichotomous branches or some- 
times with terminal whorls of 4 or 6; areole small; buds obtuse, pinkish, hairy when in flower; flowers 
scattered along branches toward tip, white to pale pink, 8 to9 mm. long, 12 to 15 mm. broad, petals 
not widely spreading (at least in our specimen); stigma-lobes 3 to 6, white; fruit white, somewhat 
depressed, 8 to 10 mm. in diameter, 7 to 8 mm. high, the base sunken in the branch. 
Type locality: Brazil. 
Distribution: Organ Mountains, Brazil. _ 
The species was described from plants brought to Paris from Brazil in 1887, their 
habitat not recorded, but Dr. Rose traced it to the Organ Mountains in 1915 and his plant 
flowered in the New York Botanical Garden in February 1921 (No. 21161). In 1902 a 
specimen was sent from Paris to the New York Botanical Garden and one specimen was 
obtained from R. Lamb, Superintendent of Parks at Manchester, England, in 1914, but 
neither has done well in cultivation. —— 
Plate xx1x, figure 4, is from a plant collected by Dr. Rose in the Organ Mountains in 
1915, which flowered in the New York Botanical Garden, February 17, 1921. Figure 227 
shows the plant received from Paris in 1902 which flowered in the New York Botanical 
Garden on March 6, 1917. -
