PLANT MATERIAL INTRODUCED 



64651 and 64652— Continued. 



64651. Plants. 



64652. Cuttings. 



The bougainvilleas are showy climbing 

 shrubs, native to South America, which 

 are adapted for growing under glass in the 

 North and out of doors in the Gulf States 

 and California. 



64653 and 64654. Gladiolus spp. Iri- 

 daceae. 



From Kirstenbosch, Cape Province, Union 

 of South Africa. Seeds presented by 

 R. II. Compton, director, National Botanic 

 Gardens, through H. L. Shantz, Bureau 

 of Plant Industry. Received August 20, 

 1925. Notes by Professor Compton. 



64653. Gladiolus callistus Bolus f. 



No. 498. A relatively new species which 



1 have not had an opportunity to look up, 

 but which belongs to the Gladiolus blan- 

 dus group. It is an extremely beautiful, 

 tall, upright-growing species of a fine 

 form and color. 



64654. Gladiolus recurvus L. 



No. 499. One of the most promising of 



our gladioli from the hybridizer's point 

 of view. The flowers are blue and quite 

 fragrant. This variety is highly regarded 

 as an ornamental, and, because of its 

 color and perfume, should also prove 

 valuable for hybridization. 



64655. Cryptostegia madagascaeien- 

 sis Bojer. Asdepiadaceae. 



From Tananarive, Madagascar. Seeds pre- 

 sented by the Chief. Agricultural Service. 

 Received July 1, 1925. 



A climbing shrubby vine, native to Mada- 

 gascar, which is grown as an ornamental in 

 South Africa and elsewhere. The leaves are 

 short and leathery, and the whitish or 

 pink flowers are 2 to 3 inches wide. Of 

 possible value as a source of rubber.

 No. 60442. 



64656 to 64660. Dioscorea spp. Dios- 

 coreaceae. Yam. 



From Rabaul, New Guinea. Tubers pre- 

 sented by G. Bryce, director of agricul- 

 ture. Received July 6, 1925. 



A collection of native yam varieties. 



64656. Allah. 64659. Mwrut. 



64657. Lama. 64660. Taniel. 



64658. Maine. 



64661 and 64682. Solanum spp. So- 

 lanaceae. 



From Lima, Peru. Tubers presented by 

 Julio Gaudron, Escuela Agricultura. Re- 

 ceived July 8, 1925. Notes by Wilson 

 Popenoe, Bureau of Plant Industry. 



64861. Solanum sp. 



Though this plant is grown at the Bo- 

 tanic Garden in Lima under the name of 

 Solanum maglia, W. E. Safcord believes 

 it is not this species. Its tubers, which 

 are more or less round in form and 1 or 



2 inches in diameter, are of no value as 

 food. The plant, however, is of interest 

 to breeders for hybridizing with the true 

 potato. 



For previous introduction, see S. P. I. 

 No. 62697. 



64661 and 64662— Continued. 



64662. Solanum tuberosum L. Potato. 



The yellow-fleshed potato is one of 

 the most interesting varieties found in 

 the Andean region, home of many re- 

 markable potatoes. The tubers are 

 rather small and have deep eyes, so that 

 they are not as easily prepared for the 

 table as those of some other varieties ; 

 but in point of quality they yield to none 

 that I have tasted. The flesh is the 

 color of American butter and has a rich, 

 nutty flavor suggesting that of the chest- 

 nut. It seems to me the variety might 

 be improved, so as to do away with the 

 objectionable eyes, and that it would 

 then be worth extensive cultivation. 



For previous introduction, see S. P. I. 

 No. 56803. 



64663. Acacia scorpioides (L.) W. F. 

 Wight (A. arabica Willd.). Mimo- 

 saceae. 



From Alexandria, Egypt. Plants pre- 

 sented by W. A. Lancaster, at the re- 

 quest of S. II. Shearer. Indianapolis, Ind. 

 Received July 10, 1925. 



According to J. H. Holland (Useful 

 Plants of Nigeria, pt. 2, p. 288), a large 

 proportion of the gum arabic of commerce 

 is furnished by this tree, which is native to 

 northern Africa and southwestern Asia. 

 True gum arabic, however, is said to come 

 only from another species, Acacia Senegal. 

 The pods and bark of A. scorpioides are 

 used for tanning, and the leaves and young 

 pods are sometimes fed to cattle. The 

 wood is hard and durable and is used in 

 India for making tools.

 No. 58379. 



64664. COIX LACRYMA-JOBI MA -YUEN 



(Rom.) Stapf. Poaceae. Adlay. 



From Peradeniya, Ceylon. Seeds presented 

 by F. A. Stockdale, Director of Agricul- 

 ture, Peradeniya, at the request of P. J. 

 Wester. Received July 11, 1925. 

 Batangas. The ma-yuen, or adlay, has 

 attracted considerable attention as a cereal 

 for tropical regions. According to Mr. 

 Wester it is better than upland rice for 

 tropical agricultural regions in being more 

 drought resistant, a heavier yielder, and 

 much less expensive to cultivate. The 

 seeds can be used largely in the same man- 

 ner as corn. 



64665. Prunus tomentosa Thunb. 

 Amygdalaceae. Bush cherry. 



From Rochester, N. Y. Bud sticks col- 

 lected by C. C. Thomas. Bureau of 

 Plant Industry. Received July 25, 1925. 

 Durant Park. The largest fruited and 



most prolific of any of the varieties in 



fruit in the park. {Thomas.) 



64666. Eucalyptus delegatensis R. T. 

 Baker. Myrtaceae. 



From Hobart, Tasmania. Sepds presented 

 by L. A. Evans, Secretary of Agriculture, 

 Agricultural and Stock Department. Re- 

 ceived September 9, 1925. 



A variety, commonly called " Gum-topped 

 stringy bark," obtained at an altitude of 

 about 3,000 feet by J. B. Milsom, near the 

 Great Lake. (Evans.) 



This tree, originally described by Hooker 

 under the name Eucalyptus gigantea, is re-
