47968 to 47973— Continued. 



47969. Cyphomandba sp. Solanace.np. Tree-tomato. 

 " Said to be edible." 



47970. Eugenia sp. Myrtacese. 



"Native name in Gunrani. Aiiiffini^npirih-ainia. A spories with round 

 cherry-colored fruit; a low slirub, very resistant to cold; fn^it Rood." 



47971. Manihot tweedieana Muell. Arg. Euphorbiacese. 



"Native name in Guarani, Owasu-mandid. The Indians claim that by 

 subjecting this species to annual cultivation, in a few years they obtain 

 an edible variety." 



47972. SoLANUM CHACOENSE Bitter. Solanaceje. Potato. 

 (8. tuberosum guaraniticum Bertoni.) 



" The tubers, thicker than those of S. commersonii, have a strong and 

 somewhat potatolike flavor and are not usually eaten. But, under 

 cultivation, there appear at times edible tubers with a potato flavor; 

 this happens also sometimes in the wild state, but as an unstable varia- 

 tion, according to my results. It is a plant worth studying, especially 

 by crossing with the common potato, for in this region it is not attacked 

 by any disease or insect; it produces two or three times a year; and It 

 thrives in dry and rather poor soils where the common potato is not 

 resistant." 



47973. Casuarina cunninghamiana Miquel. Casuarinaceae. 



From Ventimiglia, Italy. Presented by the director, La Mortola Botanic 

 Gardens. Received August 25, 1919. 



An Australian tree 30 to 40 feet high, with slender branches, staminate 

 flowers in slender spikes, and globular fruiting cones not more than a third 

 of an inch in diameter. Tlie wood is dark colored, close grained, and prettily 

 marked. (Adapted from F. M. Bailey, Queensland Flora, pt. 5, p. IJ^Bl.) 



" This species has proved hardier in the Everglades of Florida than C. 

 equisetifoUa and appears to be a much handsomer form." (David Fairchild.)

47974. Cassia angustifolia Vahl. Caesalpiniaceae. Senna. 



From Tangier, Morocco. Presented by M. Jules Goffart. Received August 

 25, 1919. 

 This plant is one of the sources of the drug known as senna. It is grown 

 extensively in India and Arabia. Watt in his Commercial Products of India 

 says of its culture: "It is sown on red or black clay loams, fairly liberally 

 ploughed and manured, the sowing being in May. Weeding has to be attended 

 to, but irrigation is hardly if ever necessary. The .season for collecting the 

 leaves is .Tune to December. The yield is said to be 1,000 pounds an acre, which 

 allows a handsome margin for profit." 



47975 to 47983. 



From St. Vincent, Cape Verde Islands. Collected by Dr. H. L. Shantz. Re- 

 ceived August 26, 1919. Quoted notes by Dr. Shantz.
