secure the seed of this fruit." (Mitchell.) An up- 

 right, sparingly branched shrub, much resembling a 

 large-leaved sumac, found in the eastern Himalayas 

 in India. The leaves, often 3 feet long, are made up 

 of 13 to 25 elliptic, acuminate leaflets, 2 to 5 inch- 

 es long, bright green above and slightly glaucous 

 beneath. The racemes of pendulous, greenish flowers 

 resemble those of a yucca, but are smaller. They are 

 followed by yellow, edible fruits, 3 to 4 inches long 

 and about 2 inches thick, filled with a whitish pulp 

 and black seeds. (Adapted from Bailey, Standard Cy- 

 clopedia of Horticulture, vol. 2, p. 974.) 



Dioscorea biilbifera (Dioscoreaceae) , 45994. Yam. 

 From Mayaguez, Porto Rico. Presented by Mr. C. F. Kin- 

 man, Horticulturist, Porto Rico Agricultural Experi- 

 ment Station. "The aerial tubers of this yam are 

 somewhat better for food than the ground tubers, ac- 

 cording to Mr. C. F. Kinman. The flesh is yellow and 

 rather strong-flavored, often practically inedible. 

 The aerial tubers are very tough-skinned and keep for 

 a long time." (R. A. Young.) 



Dioscorea pentaphylln (Dioscoreaceae), 45991. Yam. 

 From Mayaguez, Porto Rico. Presented by Mr. C. F. Kin- 

 man, Horticulturist, Porto Rico Agricultural Experi- 

 ment Station. "A rather small, smooth-skinned yam, 

 called in Porto Rico potato yam. Said by Mr. C. F. 

 Kinman to have come from Africa. The tubers, when 

 well-grown, average about 12 ounces in weight. The 

 skin somewhat resembles that of the white potato. 

 The flesh is usually white, slightly mealy when cooked 

 and mashed, and is sweet. These qualities- appear to 

 be variable and, while the yam is sometimes very good, 

 it is occasionally very poor. Of possible value for 

 central and southern Florida." (R. A. Young.) 



Dioscorea saliva (Dioscoreaceae), 45993. Yam. From 

 Mayaguez, Porto Rico. Presented by Mr. C. F. Kinman, 

 Horticulturist, Porto Rico Agricultural Experiment 

 Station. "Guinea. A large yam, said to reach a weight 

 of 20 to 25 pounds in Porto Rico, and to be of good 

 quality. It thrives there in heavy clay soil and with 

 a rather small amount of rain. .This variety appears 

 to be slightly different from those (S. P. I. No. 45990) 

 recently received from Trinidad." (R. A. Young.)
