64592. Trifolium subterraneum L. 

 Fabaceae. Subterranean clover. 



From Sydney, New South Wales. Seeds 

 purchased from Foster & Sons. Received 

 August 7, 1925. 



For previous introduction and descrip- 

 tion, see S. P. I. No. 64530. 



64593 and 64594. 



From Teneriffe, Canary Islands. Collected 

 by David Fairchild, agricultural explorer, 

 Bureau of Plant Industry, with the Alli- 

 son V. Armour expedition. Received 

 August, 1925. Notes by Doctor Fair- 

 child. 



64593. Sempekvivum canariense L. 

 Crassulaceae. 



July 10, 1925. Plants from the cliffs 

 near San Juan de la.'Rambla, not far 

 from Oro'tava. This forms an immense 

 rosette of leaves, sometimes as much as 

 14 inches across, which lies perfectly 

 flat against perpendicular walls of lava 

 rock. When there are many they give 

 the appearance of a lot of large green 

 dinner plates stuck to the cliffs. From 

 the center of these plates arise the flow- 

 ering racemes, and since the dinner 

 plates are all about to form these 

 racemes, they swell out in the middle 

 and become like mammae. The flower 

 clusters are striking but not particularly 

 beautiful, since the flowers themselves 

 are greenish in color. These could be 

 grown on the back-yard walls of the 

 homes in southern California. 



64594. Tamarix gallica L. Tamarica- 

 ceae. Tamarisk. 



July 11, 1925. The use of the tam- 

 arisk as a windbreak is almost univer- 

 sal in Algeria, Morocco, and the Canary 

 Islands. The form of tamarisk which 

 one sees everywhere appears to be 

 slightly different in Teneriffe from the 

 form which I saw in Algiers. Cuttings 

 of this were collected on the beach at 

 Grotava. We discovered there that a 

 curious slimy salty liquid was actually 

 dripping off the leaves and branches in 

 such quantities that one could not walk 

 under them without ruining his clothes. 

 Evidently the plant roots like the salty 

 water and eliminate the salt through the 

 leaves. I remember that Volkens dis- 

 cussed this feature of the tamarisk many 

 years ago in his Egyptische Arabich'e 

 Wiiste. 



64595. Heterospathe el at a Scheff. 

 Phoenicaceae. Palm. 



From Manila, P. I. Seeds presented 

 through P. J. Wester. Received August 

 7, 1925. 



A tall, unarmed palm, with a straight, 

 slender stem and long pinnate leaves, 

 growing in protected situations and where 

 the rainfall is evenly distributed. It is 

 one of the most attractive and graceful 

 palms that I have seen, and from my ex- 

 perience with it at Lamao it will make a 

 good plant for the conservatory and pos- 

 sibly a good house palm. (Wester.)

64596. Raphanus sativus L. Brassi- 

 caceae. Radish. 



From Kagoshima, Japan. Seeds presented 

 by Shiganari Kawagoe, Kagoshima Im-

perial College of Agriculture and For- 

 estry, through Masao Yoshikawa, Bureau 

 of Plant Industry. Received August 11, 

 1925. 



A late variety of Sakurajima daikon 

 (Sakurajima horse radish). All varieties 

 of Sakurajima daikon, especially the late 

 one, grow to giant size, often nearly 2 feet 

 in diameter. The shape of this late variety 

 is like a turnip, almost round, while that 

 of the early varieties is rather long. The 

 growth is mysteriously limited to Sakura- 

 jima Island, and in Kagoshima or the 

 near-by villages, scarcely more than 2 miles 

 from the island, we can not grow the real 

 giant radish. The Sakurajima daikon is a 

 very delicious vegetable, juicy and tender. 

 The planting season on Sakurajima Island,, 

 for the late variety, is about the first of 

 August. The seeds are sown in rows, 4 

 feet apart, and the distance between plants; 

 should be about 3 feet. (Yoshikawa.) 



64597. Billardiera longiflora Labill. 

 Pittosporaceae. 



From South Yarra, Victoria, Australia. 

 Seeds presented by William Laidlaw, 

 Government botanist, National Herbarium 

 of Victoria. Received August 11, 1925. 



A twining shrub, sometimes several feet 

 in length, with leaves varying from oval to 

 linear in shape and from half an inch to 

 2 inches in length. The blue flowers are 

 pendulous on solitary stems an inch long. 

 This plant grows wild along w r atercour.3es 

 in Australia and Tasmania. 



For previous introduction, see S. P. I. No. 

 61326. 



64598. Ceratonia siliqua L. Caesal- 

 piniaceae. Carob, 



From La Palma, Majorca, Balearic Islands. 

 Scions collected by David Fairchild, agri- 

 cultural explorer, Bureau of Plant Indus- 

 try, with the Allison V. Armour expedi- 

 tion. Received September 1, 1925. 



No. 188a. August 16, 1925. I found this 

 water sprout coming up from the roots of 

 a large tree of the Panesca variety which, 

 bore hermaphrodite flowers and an abun- 

 dance of large thick pods of apparently good 

 quality. This may prove to be slightly dif- 

 ferent from the typical Panesca. (Fair- 

 child.) 



64599 to 64601. Coix lacryma-jobi ma- 

 yuen (Rom.) Stapf. Poaceae. 



Adlay. 



From Buitenzorg, Java. Seeds presented by 

 P. J. S. Cramer, director, General Ex- 

 periment Station. Received September l r 

 1925. 



The ma-yuen, or adlay, has attracted con- 

 siderable attention as a cereal for tropical 

 regions. According to P. J. Wester, it is 

 better than upland rice for tropical agri- 

 culture in being more drought resistant, a 

 heavier yielder, and much less expensive to 

 cultivate. The seeds can be used largely 

 in the same manner as corn. 



64599. Djoli bras. 



64600. Djoli brasoruin. 



64601. Djoli Hetan.
