Dioscorea sp. (Dioscoreaceae) , 47564. Yam. FromBahia, 

 Brazil. Tubers p^.sented by Mr. V. A. Argollo Ferrao. 

 " ' Inhame figado de piru, ' or 'caissara 1 {turkey-liver 

 yam, - on account of the shape of the aerial tubers]. 

 This very interesting inhame is cultivated here in 

 some localities but is rare and is not found In the 

 markets. The tubercles are borne on the vine. I had 

 a few last year and planted them in December, when 

 they were starting. I am now (April 28) picking the 

 crop. The tubercles I have eaten were boiled and I 

 found them very good. I think it is a plant worth propa- 

 gating, for it gives an excellent substitute for the 

 potato, is productive, and the tubercles keep for 

 several months without deterioration." (Argollo.) 



Do'iekos lablab (Fabaceae), 47568. Bonavict bean. From 

 St. Vincent, B. W. I. Seeds presented by Prof. S. C. 

 Harland, assistant for cotton research, Agricultural 

 Experiment Station. " 'St. Vincent Bush. ' I discovered this 

 type in a peasant's holding in St . Vincent in the spring 

 of 1915 and found that it bred true when put into 

 pedigree culture. Under cultivation it produces a 

 wiry bush of from 1| to 2 feet in height, and bears a 

 heavy crop when environmental conditions are favora- 

 ble. As a cover crop for orchards in Florida I think 

 it is worth a trial. With me the plants of the bush 

 Dolichos always flower when 5 weeks old and ripe pods 

 are produced at 8 weeks. Often a second crop of pods 

 is produced. The beans are quite palatable, though 

 they are inferior to Lima beans. I should mention 

 that in the course of my inheritance studies on 

 Dolichos, I have established that the bush form behaves 

 as a simple Mendelian recessive to the climbing form. 

 In a cross between 'St. Vincent Bush' (white ) and 'Purple 

 Soudan' climber, I have isolated pure bush types of 

 varying vegetative habits. Some are much more vigorous 

 than the original bush parent. I have also succeeded 

 in isolating a bu c ^ form of 'Vilmorin's Stringless,' 

 by crossing 'Stringless,' with the native bush."
