47578 and 47579— Continued. 



47579. PuERARiA THUNBEBGiANA (Sieb. and Zucc.) Benth. Fabacefe. 



Kudzu. 



" The kudzu vine is a large-leaved, rapid-growing legume, native to 

 Japan. It succeeds well in nearly all sections of the United States. It 

 is an excellent vine for arbors or wherever a quick cover is required. It 

 furnishes an abundant and nutritious forage, and is of value for plant- 

 ing on rocky land or hillsides where cultivation is difficult. The roots 

 produce starch of good quality." {J. H. Johnson.) 



In moist, rich woodland it becomes a troublesome weed. 



47580 to 47583. 



Plants grown at the Plant-Introduction Field Station, Brooksville, Fla. 

 Numbered for convenience in recording distribution in June, 1919. 



47580. Acacia longifolia (Andrews) Willd. Mimosacese. 



A bushy acacia, useful for binding coast sands since the lower branches 

 root very readily and spread quickly. The bark, while not so tiigh in 

 tannin as that of Acacia mollissima, is used chiefly in tanning sheep 

 skins. (Adapted from Mueller, Select Extra-Tropical Plants, p. 7.) 



47581. Hypericum canariense L. Hypericacese. St.-Jotin's-wort. 

 " A species native to the Canary Islands. It forms a shrub up to 15 



feet in height. The leaves are oblong lance shaped, narrowed at the 

 base, and 2 to 3 inches long. The flowers, produced in panicles, are 1 to 

 li inches across. Similar to Hypericum floribundum." (J. H. Johnson.) 



47582. BuLBiNE LONGiscAPA (Jacq.) Willd. Liliaceae. 



" A stemless, liliaceous perennial with a small tuberous rootstock— 

 allied to Anthericum. The leaves are fleshy and vei-y glaucous, 8 to Vi 

 inches in length. The flower spike is a foot or more long, and the flowers 

 are bright yellow, one-third of an Inch long, the perianth segments re- 

 flexing when fully expanded. The capsule is the size of a pea. The 

 plant is native to South Africa." (J. H. Johnson.) 



47583. Agave verschaffeltii Lem. Amaryllidaceae. 



A variable species from southern Mexico, many named varieties being 

 in cultivation. The leaves are 3 inches wide by G to 8 inches long, 

 glaucous, tipped with red-brown spines and armed with long, rusty teeth 

 on large, fleshy prominences. The inflorescence is rather sparse.

 p. 233.) 



47584 to 47592. 



From Colombia. Collected by Mr. Alfred Lenz, Flushing, Long Island. 

 Received June 16, 1919. Quoted notes by Wilson Popenoe. 



47584. AcHRAS zapota L. Sapotacese. Sapodina. 

 "The sapodilia or chicuzapote is the best of the sapotaceous fruits. 



It is common in many parts of tropical America (found wild In several 

 re-ions) and is cultivated successfully in southern Florida, where it 

 merits commercial exploitation. The fruits, which are picked when 

 still hard, can be shipped to distant markets. Choice varieties should 

 be propagated by budding."
