28 SEEDS AND PLANTS IMPORTED. 



47532. Ipomoea cairica (L.) Sweet. Convolvulacese. 



(/. palmata Forsk.) Moming'-glory, 



From Zaiiilioanga. Philippine Islands. Presented by Mr. P. J. \Yester, agri- 

 cultural adviser. Received May 28, 1919. 



" Seeds of a white-flowered variety of Ipomoea cairica, extremely attractive 

 and floriferous. Unlike most plants of this family, /. cairica is everblooming. 

 Tlie mauve-colored variety is the most popular climber in the Philippines and 

 very rarely seeds, being propagated by cuttings. The plant from which these 

 seeds were obtained is the only one I have seen with white flowers." (M'ester.) 



47533. Fkagaria insularis R^db. Rosacea?. Strawberry. 



From Kingston, Jamaica. Pre.sented by Mr. W. Harris. Hope Gardens. 

 Received May 29, 1919. 



The '• wild strawberry "' of Jamaica. Introduced for breeding experiments 

 in developing new varieties of strawberries. 



47534 and 47535. Pruxus spp. Amygdalacese. 



From Chevy Cha.se, Md. Collected by Dr. David Fairchild. at his home 

 " In the AVoods." Received June 3. 1919. Quoted notes by Dr. Fair- 

 child. 



47534. Prcnus subhirtella avtumnalis Makino. 



" Seed from a tree of the October blooming Japanese flowering cherry 

 tree imported from the Yokohama Nursery Co., Yokohama. Japan, in 

 1906. I suggest it as a stock for commercial cherries because of its un- 

 usual vigor. Its truuk has lieen vei-y free from disease, it does not sucker, 

 its seedlings are not subject to the usual leaf blight {Ci/Undrosporium 

 padi), and its seeds are regularly produced. The flowers are single and. 

 are produced both in autumn (October) and spring (about April 1)." 



47535. Prinis subhirtella pendula (Sieb. ) Tanaka. Rosebud cherry. 

 " Seed gathered from drooping Japanese cherry trees imported in 1906 



from the Yokohama Nursery Co.. Yokohama, Japan. The unusual vigor 

 of these drooping cherry trees, the fact that they belong to a long-lived 

 species which in Japan grows to be 300 years old. combine<l with the 

 facts that the leaves of the seedlings are free from the CiiiindroHporium 

 padi disease which attacks the ilazzard seedlings, that their trunks are 

 vigorous and are free from disease such as gummosis. and also that the 

 trees bear abundant crops of seeds, would seem to indicate that it is 

 worth testing as a stock for our cultivated cherries, providing it should 

 prove congenial. I have gi-own seedlings, and find that though uniformly- 

 vigorous some have the drooping habit whereas others are upright in 

 growth, agreeing with the prototype which Wilson says occurs wild in 

 tlie mountains of China and Japan and which he has callevl variety 

 ascendens. No leaf blight has been observed among them. Gathered 

 June 5 or 6, 1919." 



47536. Xanthosoma sp. Araceae. Yautia. 



From Huigra, Ecuador. Corms grown until .Tune, 1919, in the Department 

 of Agriculture greenhouse, from material collected in September, 1918, 

 by Dr. J. N. Rose, associate curator, U. S. National Herbarium. 

 "(No. 22574.) Found in a semiarid region, among cacti and other dry-land 

 plants on a gravelly hillside, at an altitude of 4,000 feet." {Rose.)
