﻿50 SEEDS AND PLANTS IMPORTED. 



42052 to 42054— Continued. 



42052. Dioscoeea sp. Manawa yam. 

 " A very peculiar yam which appears to be distinct from the white 



yampee, the Mapues yampee of Porto Rico, or any of the wild sorts I 

 have ever seen. We are calling it the Manaicd yam, from the plantation 

 where I am trying it near Colon. About nine months ago I obUiined two 

 small roots from a Panaman, who admitted they were not commonly 

 cultivated even in Panama. They may be native to the Darien region. 

 From one hill (planted in April, I believe), we harvested some 6 or 8 

 pounds in November, and the vines are still (December 24) producing. 

 It is a heavy yielder and two or three months earlier than the Dioscorea 

 alata or D. sativa types. It is slightly sweet and has a flavor all its 

 own, and practically no rag. The size and shape impress me strongly. 

 The skin is of a distinct type, potatolike. This, with the attractive 

 shape, individual size, and mealiness, will, I believe, make the Manawd 

 very popular." (Barrett.) 



" When baked the skin is bitter and can not be eaten." (R. A. Young.) 



See S. P. I. No. 39705 for previous introduction.

42053. Dioscorea trifida L. 1 Dioscoreaeea?. White yampee. 

 " From Bracho plantation, near Colon. Second crop. Probably Dios- 

 corea trifida." {Barrett.) 



"The quality is excellent, the flesh being white and mealy." (R. A. 

 Young. ) 



For an illustration of the tubers of the white yampee, see Plate V. 



42054. Dioscorea sp. Dioscoreacese. Yampee. 

 "From Bracho plantation, near Colon. Second crop." (Barrett.) 



" The quality is fair ; the flesh is very slightly pink and is rather 

 firm." (R. A. Young.) 



The tubers of this introduction were received mixed with those of the 

 white yampee, S. P. I. No. 42053, but on account of the marked difference 

 in appearance and quality they were separated and given different 

 numbers. 



For an illustration of this form of yampee, see Plate VI. 



42055 and 42056. 



From Joinville, Brazil. Presented by Mr. Jean Knatz. Received March 

 3, 1916. 



42055. Carica papaya L. Papayaceae. Papaya. 

 A rapid-growing fruit tree, reaching a height of 25 feet in 10 months 



and bearing numerous melon-shaped fruits on the trunk. Good varieties 

 are deliciously sweet, with a characteristic flavor. They are relished 

 as a breakfast fruit and are easily digested, as they contain a powerfuJ 

 papain ferment. 



42056. Phaseolus calcaratus Roxb. Fabacese. Rice bean. 

 " The plant is strictly an annual and half twining in habit. Planted 



in rows the different varieties grow 12 to 30 inches high and produce 

 vining branches 3 to 6 feet long. The leaves closely resemble those of 

 the common bean, but not infrequently are three lobed. The flowers are 

 bright yellow, produced in racemes of 10 to 20. The pods are smooth,
