Triehoscypha sp. (Anacardiaceae) , 47519. From 

 Loanda, 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 peachllke, 

 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. 

 Nehrling, Palm Cottage Gardens, Gotha, Fla. , gives 

 the following information: 



"May 30, 1907, I received from you a tuber of 

 DiJscorra divaricata, S. P. I. No. 10312, which has proved 

 a great success. It is as good as the best potato, 

 and is 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 

 yallow, limpid liquid having a very slight odor and a 

 specific gravity of 0.9371 at 15.6 C. (60 F.)"
