Larix potaninii Batalin. (Pinaceae.) 43851. Plants 

 of larch from Jamaica Plain, Mass. Presented by the 

 Arnold Arboretum. A tree from western China, from 60 

 to 70 feet high, with yellowish young shoots and some- 

 what rectangular pointed leaves about an inch long. 

 The cones are egg-shaped, and about 1$ inches long. 

 This tree has much the aspect of the common larch, 

 and according to Mr. E. H. Wilson it yields the most 

 valuable timber in China. (Adapted from Bean, Trees 

 and Shrubs Hardy in the British Isles, vol. 2, p. 9.) 



Mains arnoldiana Rehder. (Malaceae.) 43857. Cuttings 

 from Jamaica Plain, Mass. Presented by the Arnold Ar- 

 boretum. This is a hybrid of Mains floribunda with one 

 of the hybrids of Mains baceata, and appeared spontan- 

 eously in the Arnold Arboretum several years ago. It 

 makes a smaller tree than M. floribunda, but its long 

 spreading and arching branches are very graceful, and 

 the flowers produced on long stems are more than twice 

 as large as those of M. floribunda. These flowers are a 

 beautiful pink, and it is considered by some persons 

 to be the most beautiful of the crabapples. (Adapted 

 from the Arnold Arboretum, Bulletin of Popular Inform- 

 ation, Nos. 3, 1911, and 39, 1913.) 



Moringa oleifera Lamarck. (Moringaceae . ) 43761. Seeds 

 from Matania El Saff, Egypt. Presented by Mr. Alfred 

 Bircher, Middle-Egypt Botanic Station. "The pods of 

 this variety are free of the bitter taste of the com- 

 mon horse radish tree, and are eaten like the French 

 beans if gathered when in a young state." (Bircher.) 



Persea americana Miller. (Lauraceae.) 43932. Cut- 

 tings of avocado from Coban, Depto. de Alta Verapez, 

 Guatemala. Collected by Mr. Wilson Popenoe, Agricul- 

 tural Explorer for this Department. "From the yard 

 of Filadelfo Pineda, called de San Marcos. A fruit 

 of medium size, obovoid to pyriform in shape, green, 

 with a rather small seed and flesh of exceptionally 

 rich flavor and good quality. My attention was called 

 to this tree by Mr. R. W. Hempstead, who recommended 

 it as the finest avocado he had eaten in Coban. The 

 tree is said to be a heavy bearer, but this is an off 

 year in Coban and it is not bearing a large crop. 

 Form obovoid, tending to become pyriform, slightly 

 oblique; size about medium, weight 15 ozs., greatest 

 length 4| inches, breadth 3| inches; base rounded, 

 the stem inserted obliquely without depression; apex
