ber and continues until April, coming probably from different altitudes. 

 The size is that of a rather small cherry and the color a deep reddish 

 purple, becoming nearly black with maturity. The leaves, stems, and hark 

 are strongly charged with prussic add and are very bitter to the taste 

 The trees are usuallj 20 to 30 feet high, but often of large size. 40 feel 

 or over, with trunks 2 feet in diameter. Many are found in a wild or 

 half-wild state, quite independent of cultivation. This was observed 

 particularly in the neighborhood of Sieuani at an elevation of about 12,000 

 feet. Nevertheless, it is not certain that the species is a native of 

 Peru. At Lima the same name, capuli, is applied to an altogether differ- 

 ent type, a small plant of the genus Physalis, related to the tomato, but 

 with the fruits small and inclosed in a large papery calyx like the so- 

 called strawberry tomato, known in some parts of the United States. As 

 the capuli tree appears to be a healthy, vigorous, rapid-growing type, it 

 may be worthy of a trial along the Pacific coast. The possibility of using 

 it as a stock for other cherries or for the production of desirable hybrids 

 is also worth considering, but the species is not closely related to our 

 cultivated cherries and may need to be looked upon as a distinct type to 

 be improved through selection rather than by hybridization." 



41329. Datura sanguinea Ruiz and Pavon. Solanacese. 



Puca campacho. 

 "(No. 1915. Peru, July 14, 1915.) Seeds from above Pinasniocj, Pan- 

 ticalla Pass, at an altitude of about 12,000 feet. A large treelike species, 

 somewhat smaller than D. arhorca, with smaller leaves and more nar- 

 rowly tubular flowers. The corolla tube is green at the base, orange 

 yellow in the middle, and scarlet at the mouth. In addition to these 

 striking differences, the species should be much more hardy than /). arho- 

 rca, which appears in Peru to be a native of the lower tropical valleys, 

 while D. sanguinea extends to the high altitudes where heavy frosts are 

 encountered every night." 



41330. Lupin us cbuckshanksii Hooker. Fabacese. Tarhui. 

 "(No. 1919. Seeds from Ollantaytambo, Peru. July 20, 1915.) Appar- 

 ently a native species, commonly cultivated at altitudes of 9,000 to 11,000 

 feet. The pods are very thick and fleshy, with distinct but not promi- 

 nent irregular veins; the surface glaucous and somewhat pubescent, but 

 not very densely so. Flowers very handsome, the banner erect, blue at 

 the sides, then white, but yellow in the lower half of the middle, the 

 lower petals deeply blue, covering the whitish keel. Flowers usually in 

 whorls of five, four, or three. Leaves naked above, sparsely hairy be- 

 neath, glaucous. Seeds pure white. Said not to yield very well. After 

 being ground into meal this has to be soaked several days in running 

 water to extract the bitter taste: considered a delicacy, notwithstanding 

 the difficulty of preparation." 



41331. Passift.ora sp. Passitloraceae. Tumbo. 

 "(No. 1922. Seeds from Ollantaytambo, Peru, July 19, L915.) Leaves 



somewhat like that of the Tinta species, hut upper surface much 

 smoother and under surface not so cottony, flowers without fringe, 

 very similar to those from Tinta, except for the absence of tentacles, 

 involucre with bracts united, and fruit with yellow pulp, attaining a 

 length of 3 cm. and a width of I cm. The skin surrounding the pulp 

 very thin and tough, surface of fruit strongly pubescent, with simple
