52788 to 52795. 



From Stockholm, Sweden. Seeds presented by Dr. Robert E. Fries, director, 

 Hortus Botanicus Bergianus. Received March 25, 1921. 



52788. Aralia cachemikica Decaisne. Araliaceae. 



A lax shrub 5 to 10 feet high, with 1 to 3 pinnate leaves pilose above and 

 glabrous or hispid ou the veins beneath. The umbels are in elongated 

 panicles a foot long. (Adapted from Hooker, Flora of British India, vol. 

 2, p. 722.)

52789. Chekopodium bonus-henricus L. Chenopodiaceap. 



Good King Henry. 

 An exti'emely hardy perennial, native to Europe, with a smooth, slightly 

 channeled stem 2 to 3 feet high. The arrow-shaped, smooth dark-green 

 leaves are frosty or mealy on the under surface and rather thick and 

 fleshy. The small green flowers are in close compact clusters, and the 

 small black seeds hold their viability for five years. The leaves are eaten 

 like spinach and the shoots like asparagus as a very early vegetable 

 blanched by simply earthing them up. These delicious shoots are 

 abundant a fortnight before asparagus comes in and for some weeks after- 

 wards. (Adapted from Robinson, The Vegetable Garden, p. 313.) 



52790 to 52792. Datura stramonium L. Solanaceje. 



52790. " Variety inerniis. This is a recessive variety of Datura 

 stramonium. It may be either white flowered or lavender flow- 

 ered and is readily distinguished from the typical form in having 

 capsules devoid of prickles." {W. E. Safford.) 



52791. Received as Datura leichhardtii, but the seeds agree with 

 those of D. stramonium. 



52792. " Variety tatula. This variety is distinguished from the 

 typical Datura stramonium by its lavender flowers and purple stem. 

 The prickly pods are indistinguishable in form from those of the 

 type. This is the dominant form of D. stramonium. The white- 

 flowered type as well as the smooth-capsuled form usually called 

 D. inermis are both recessive forms of the same species." (W. E. 

 Safford.) 



52793. Datxhia sp. Solanacese. 



Received as Datura ekblomii, for which name a place of publication 

 has not been found. 



52794. Elymus arenakius L. Poaceae. Lyme-grass. 

 A stout erect perennial 2 to 4 feet high, with extensively creeping 



rootstocks, rather firm, flat sharp-pointed leaves, and terminal, usually 

 densely flowered spikes. Found in maritime sands of Greenland and 

 Labrador to Maine. Alaska to California, and on the shores of the 

 Great Lakes. This grass is one of the best species known for binding 

 drifting sands, and in northern Europe it has been cultivated with 

 beach-grass (Ammophila arenaria) for this purpose, the two species 

 forming an admirable combination. The seeds are used for food by the 

 Digger Indians of the Northwest. (Adapted from United States De- 

 partment of Agriculture, Division of Agrostology Bulletin No. 1, p. 307.)
