Larix potaninii Batalin. (Plnaceae.) 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.) 
Malus arnoldiana Rehder . (Malaceae.) 43857. Cuttings 
from Jamaica Plain, Mass. Presented by the Arnold Ar- 
boretum. This is a hybrid of Malus floribunda with one 
of the hybrids of Malus baecata, 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 Matanla El Saff , Egypt. Presented by Mr. Alfred 
Blrcher, 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 amerieana 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
