63542 to 63544. Solanum tuberosum 

 L. Solanaceae. Potato. 



From Klein Wanzleben, Germany. Tubers 

 presented by Dr. Phil. Oskar Rabbethge. 

 Received April 2, 1925. Notes by Doctor 

 Rabbethge. 



European varieties, not in the American 

 trade, introduced for potato-breeding ex- 

 periments. 



63542. Centifolia. A cross between 

 Borcken and Flora, originated by the 

 plant breeder Von Kameke. It is a 

 red-skinned, white-fleshed table variety, 

 and is very healthy. Season medium 

 and yield large. 



63543. Industry. A cross between Rich- 

 ter's Early and Simon, originated by 

 the plant breeder Modrow. It is 

 grown on heavy soil. In western Ger- 

 many it is the predominating yellow- 

 fleshed table variety. It is a heavy 

 yielder, matures late, but is susceptible 

 to rot. 



63544. Pepo. A cross between Deutsches 

 Reich and Jubel, originated by the 

 plant breeder Von Kameke. A light 

 yellow-fleshed table variety, of very 

 large yield. Resistant to rot and 

 scarcely susceptible to fungous dis- 

 eases ; very resistant to wart disease. 

 The lilac-colored flowers are inclined 

 to vary. 



63545. Trifolium repens L. Fabaceae. 

 White clover. 



From Edinburgh, Scotland. Plants pre- 

 sented by William Wright Smith, regius 

 keeper, Edinburgh Botanic Garden. Re- 

 ceived April 4, 1925. 



Obtained from the Scottish Board of 

 Agriculture. (Smith.) 



Sent in response to a request for mate- 

 rial of the brown-leaved strain of white 

 clover ; to be tested by clover specialists. 



63546. Saccharum officinarum L. 

 Poaceae. Sugar cane. 



From' Fortuna, Porto Rico. Cuttings pre- 

 sented by I. Mutz, through E. W. Bran- 

 des, Bureau of Plant Industry. Re- 

 ceived April 1, 1925. 



H 109. 



A locally developed strain. 



63547 and 63548. Pisum sativum L. 

 Fabaceae. Pea. 



From Valence sur Rhone, France. Seeds 

 obtained from Tezier Fre-res. Received 

 April 2, 1925. 



Locally grown strains. 



63547. Mange-tout violet. 



63548. ticrpette frangaise. An improved 

 form with long pods. 



63549. Eleocharis tuberosa (Roxb.) 

 Schult. Cyperaceae. 



From Canton, China. Tubers collected by 

 F. A. McClure, agricultural^ explorer, 

 Bureau of Plant Industry. Received 

 April 3, 1925. 



No. 29. Ala tai, Hon ma tai. A variety 

 of ma tai which differs in its cultural 

 methods from the ordinary variety in that 

 the irrigation water is withdrawn some time 

 before the crop is ripe. The harvesting 

 method is affected profoundly because with 

 the variety commonly grown around Canton 

 the crop is searched for blindly by women 

 standing knee deep in mud and water, but 

 with this variety the harvesting is done 

 with a hoe, resulting in much less ex- 

 penditure of labor. The culture of ma tai 

 is rather complicated in that the corms are 

 put through two preliminary " plantings " 

 before they finally reach the field in which 

 they produce. At the end of June or early 

 in July the corms are set thickly in a bed 

 and barely covered with soil. They are kept 

 moist, and when their sprouts are 6 or 7 

 centimeters long they are transplanted to 

 a wet culture plot and set about 1 foot 

 apart each way. When the sprouts are 

 about 30 centimeters high they are again 

 transplanted to a wet culture field, usually 

 one from which the first rice crop has just 

 been harvested, and this time set about 3 

 feet apart in rows 3 feet apart, and alter- 

 nated so that each plant is equally distant 

 from all of its adjacent neighbors. Hence- 

 forth they are irrigated much the same as 

 rice. When the plants become established 

 each is given a small handful of powdered 

 bean or peanut cake. The irrigation is 

 discontinued in October. (McClure.} 



63550. Citrus aurantium L. Ruta- 

 ceae. Sour orange. 



From Algeria. Seeds collected by David 

 Fairchild, agricultural explorer, Bureau of 

 Plant Industry. Received April 6, 1925. 



From the Jardin d'Essais, Maison Carree. 

 To be tested by citrus growers as a root- 

 stock in comparison with strains of the 

 same species already growing in the United 

 States. 



63551. Alpinia sp. Zinziberaceae. 



From Kwangtung Province, China, Rhi- 

 zomes collected by F. A. McClure, agri- 

 cultural explorer, Bureau of Plant 

 Industry. Received April 3, 1925.
