TricJir.scypha sp. ( Anacardlaceae ) , 47519. Prom 
Lcanda, Angola, Africa. Seeds presented by Mr. J. 
Gossweiler. "No. 6882. A dioecious, palm-shaped tree, 
25 meters In height, which produces on its trunk, about 
2 meters above the ground, large bunches of peachlike, 
edible, succulent fruits. Quite a distinct, curious, 
and ornamental plant from the Portuguese Kongo. March, 
1919." (Gosswieler . ) 
Notes on Behavior of Previous Introductions. 
A letter received May 21, 1919, from Dr. H. 
Nehrllng, Palm Cottage Gardens, Gotha, Pla. , gives 
the following information: 
"May 30, 1907, I received from you a tuber of 
Diosco ca divarieata, S. P. I. No. 10312, which has proved 
a great success. It is as good as the best potato, 
and 18 a most valuable root crop. The plant makes a 
tremendous growth - I have measured vines that were 
60 feet long - and in rich, rather moist soil the tubers 
attain a weight of over a hundred pounds in two years. 
The foliage is very dense and the stems are provided 
with blunt spines. It flowers late in November and 
the three-cornered blossoms, almost pure white, exhale 
a delicious perfume. 
"My Aleurites fordii (S. P. I. No. 21013) is now a 
fine tree 25 feet high. Several seedlings, only a year 
old, and a foot high, flowered and set fruit." 
The following analysis by Dr. Frederick B. Power, 
of the Bureau of Chemistry, will interest all those 
who have grown this attractive tree, Pongam pinnata, 
which flourishes luxuriantly in south Florida. 
"The perfectly sound seeds amounted to 7,548 
grams, and, on separating the kernels from the shells, 
the weight of the kernels was found to be 3,811 grams, 
or 50.5 per cent of the weight of the entire seed. A 
portion of the kernels was completely extracted with 
ether, when the yield of the fatty oil was 26.97 per 
cent. This would be equivalent to 13.4 per cent of 
the entire seed. The oil thus obtained was a pale 
yellow, limpid liquid having a very slight odor and a 
specific gravity of 0.9371 at 15.6° C. (60° F.)"
