 ROSUM. Solanacese. 



From Wolverhampton, England. Tubers pre- 

 sented by F. W. Keay, Wolverhampton, through 

 William Stuart, Bureau of Plant Industry. Re- 

 ceived February 2, 1924. 



A cross between Solanum demissum and the 

 Paterson's Victoria variety of the potato. 



For use in potato-breeding experiments. 



58472. Trifolium pratense L. Fa- 

 bacese. Red clover. 



From Valence, Rhone, France. Seeds purchased 

 from Tezier Freres. Received March 12, 1924. 



Locally grown clover from Nimes, Gard. Intro- 

 duced for testing by clover specialists. 



58473. Viburnum hanceanum Maxim. 

 Caprifoliacese. 



From Ottawa, Canada. Seeds presented by_J. 

 Adams, botanist, Central Experimental Farm, de- 

 partment of Agriculture. Received February 18, 

 1924. 



A hardy, bushy, deciduous shrub from southeast- 

 ern China, where it becomes 6 to 10 feet in height. 

 The branches are mostly horizontal, and the round- 

 ish, slightly toothed, sharp-pointed leaves are dull 

 dark green above and pale grayish beneath. The 

 inflorescence consists of a flat umbel 2 to 4 inches 

 across; the center is filled with small, perfect, incon- 

 spicuous flowers, surrounded by a few large white 

 imperfect flowers about an inch wide. The roundish 

 egg-shaped fruits are at first coral red and finally 

 blue-black. 



Introduced for horticulturists engaged in small- 

 fruit breeding. 



58474. Amygdalus communis X per- 

 sica. Amygdalacese. 



Peach-almond hybrid. 



From Benenden, Kent, England. Budwood pre- 

 sented by Collingwood Ingram. Received Feb- 

 ruary 20, 1924. 



This "peach-almond" hybrid is very vigorous. 

 The original scion came from Quinta de Seixo in the 

 upper Douro District, Portugal. The fruit appears 

 to be intermediate in characters between the peach 

 and the almond. (Ingram.) 



58475. Trifolium pratense L. Fa- 

 bacese. Red clover. 



From Wellington, New Zealand. Seeds presented 

 by A. L. Cockayne, director of the fields division, 

 Department of Agriculture. Received February 

 20, 1924. 



"Hunciman's red clover. This has been thor- 

 oughly tested and may be regarded as the only true 

 perennial strain of red clover in New Zealand." 

 (New Zealand Journal of Agriculture, vol. 22, p. 290.) 



Introduced for testing by clover specialists. 



58476 and 58477. Trifolium pra- 

 tense L. Fabacese. Red clover. 



From Copenhagen, Denmark. Seeds purchased 

 from L. R. M. Larsen, Danish Royal Agricultural 

 Society. Received February 23, 1924. 



Both of these are Danish strains which in this 

 country have given considerably greater yields than 

 foreign seeds. (Larsen.) 



Introduced for agronomists engaged in clover 

 breeding. 



58476. Tystofte No. Ifi, an early strain. 



58477. Her snap, a late strain. 



58478. SlDEROXTLON AUSTRALE (R. 



Br.) Benth. and Hook. Sapotaceae. 



From Sydney, New South Wales. Seeds presented 

 by J. H. Maiden, director, botanic gardens. 

 Received. February 12, 1924. 



A tree, sometimes becoming of considerable size, 

 from southeastern Australia, where it is called 

 "wild plum" or "black apple" because of the fruit. 

 The latter is the size of a small apple; the rich, 

 milky juice resembles cream in taste, but the flesh 

 is coarse and insipid. The pale-yellow wood is close 

 grained, handsomely veined, and suitable for cab- 

 inetwork, although it requires careful seasoning. 

 This species is now introduced for testing the sap 

 as a possible source of rubber.

58479. Colocasia esculenta (L.) 



Taro. 



Schott. Aracese. 



From Canton, China. Tubers presented by F. A. 

 McClure, Canton Christian College. Received 

 May 22, 1922. Numbered January, 1924. 



Pan Long Oo. Introduced for cultural and com- 

 parison tests. 



58480. Citrus ichangensis Swingle. 

 Rutacese. 



From New Orleans, La. Seeds presented by E. 

 Foster. Received February 19, 1924. 



These seeds are from a tree sent to New Orleans 

 from the Arnold Arboretum, Jamaica Plain, Mass. 

 The trees at the arboretum were raised from seeds 

 collected in China several years ago from trees 

 which appeared to show unusual frost resistance. 

 The general character of the fruit is much like the 

 bitter Seville orange used in the manufacture of 

 Scotch marmalade, being very rough, with a thick, 

 reddish skin. It is not very juicy, and the seeds 

 are large. The species, because of its unusual 

 hardiness, will be useful for breeding purposes. 

 (Foster.) 



A spiny shrub or small tree, 5 to 15 feet high, 

 native to central and southwestern China. It 

 differs from other members of the genus chiefly 

 in its very large, thick seeds and its slender leaves, 

 which are four to six times longer than broad. It 

 is also one of the hardiest species of Citrus known. 



58481. Ailanthus vilmoriniana Dode. 

 Simaroubacese. 



From Paris, France. Plant purchased from Vil- 

 morin-Andrieux & Co. Received February 26, 

 1924. 



Although this species is closely related to the 

 tree of heaven (A. altissima), well known in many 

 parts of the United States, it is distinguished by 

 the numerous soft spines on the young branchlets 

 and by the very downy leaflets. The main leaf- 

 stalk is often rich red and occasionally spiny like 

 the leaflets. The inflorescence is sometimes a foot 

 or more across, and the samara, or key, is 2 inches 

 long. The tree is native to Szechwan, western 

 China. 



58482. Rumex abyssinicus Jacq. Poly- 

 gonacese. 



From Java. Seeds presented by W. A. Orton, 

 Bureau of Plant Industry. Received February 

 23, 1924. 



As a source of greens during the hot summer 

 months, the Abyssinian Rumex appears to have 

 merit. Seeds may be sown in the greenhouse or 

 hotbed in early spring and the plants set out as soon 

 as the soil can be worked. The plants grow 7 or 8 

 feet in height and continue to yield greens until cut 

 down by frost in late autumn. The leaves are 

 cooked and served in the same manner as spinach, 

 but care must be taken to change the water, in 

 cooking, to eliminate excessive acidity.
