Aleetryon exeelsum ( Sapindaceae ) , 48164, From Auck- 
land, New Zealand. Seeds presented by Mr. H. R. Wright. 
"A handsome, evergreen tree, commonly called the New 
Zealand oak." (Wright.) 
A tree 30 to 60 feet high, with black bark, and 
with the young branches, undersurf aces of the com- 
pound leaves, panicled inflorescence, and capsules 
clothed with silky ferruginous pubescence. The globose 
shining jet-black seeds, from which the Maoris form- 
erly extracted an oil, are half imbedded in a scarlet, 
fleshy, cup-shaped aril. The tree yields a tough, e- 
lastic timber valuable for ax handles. (Adapted from 
Cheeseman, Manual of the New Zealand Flora, p. 103.)

Avena sativa (Poaceae), 48088. Oats. From Johannes- 
burg, Transvaal. Purchased from the Agricultural Sup- 
ply Association, through Mr. J. Burtt-Davy, botanist. 
"Boer Oats. The principal oats grown for forage, i.e., 
oat hay, before the Anglo-Boer War, and valued for the 
fineness of its straw. Almost ousted by the Algerian 
oat, and now very rare. Boer oats always contain some 
black oats among the brown. The glumes have a char- 
acteristic rougbness which readily distinguishes this 
variety from Algerian oats. Grown under irrigation."

Avena sativa (Poaceae), 48109. Oat». From Mel- 
bourne, Victoria. Presented by Prof. A. E. V. Richard- 
son, agricultural superintendent. "Ruakura. A rust- 
resistant oat developed from a single plant of Argen- 
tine oats selected by Primrose McConnell, of the Rua- 
kura Experiment Farm, New Zealand, in 1908. This va- 
riety appears to be resistant to both stem and crown 
rust in the United States, but experiments here indi- 
cate that it has little commercial value. It is of 
probable interest to plant breeders." (C. W. Warburton. ) 
"It has never been claimed that the new oat is 
rustproof. What can be claimed is that it is the most 
resistant to disease of all the varieties tested at 
Ruakura." (Journal of Agriculture, New Zealand, vol. 
6, p. 133. ) 
"This oat was imported from New Zealand, it hav- 
ing originated as a variation in a crop of Argentine 
oats at the Ruakura Experiment Farm, in the Dominion. 
It is claimed that It is rust resistant and a wonder- 
ful yielder. It has not been tried sufficiently long
