an inch and a half in thickness. The flesh is bright 
orange color; I do not believe it is edible,- at any 
rate, it is not eaten by the natives of this region."

Triticum aestivum (Poaceae), 46815. Wheat. From 
Johannesburg, South Africa. Seed presented by Mr. J. 
Burtt-Davy, Agricultural Supply Association. "Rietti. 
Bearded; ear long and open, shedding rather too easily. 
It stools well and is a heavy yielder, especially in 
wet, late seasons; wonderfully rust-resistant. The 
grain is dark but the flour is very white and the va- 
riety is greatly valued as a milling wheat. This is the 
most extensively grown wheat in the Western Province 
(Uganda), though 'Glujas Early' threatens to oust it 
from this position. It has not given very good results 
in the region of summer rainfall." (Burtt-Davy.) 
Tritieum aestivum (Poaceae), 46817. Wheat. Prom 
Johannesburg, South Africa. Seed presented by Mr. J. 
Burtt-Davy, Agricultural Supply Association. "Glujas Early. 
Beardless or semibearded; white; excellent quality; 
good yielder; does not shell out too easily. This is 
probably the most rust-resistant of all the white va- 
rieties of wheat yet introduced into the Western Province 
(Uganda), and stands second only to 'Rietti' in the 
acreage under cultivation in the principal wheat areas. 
It is annually gaining in popularity with every pros- 
pect of ousting 'Rietti' from the premier position. 
Now largely grown in the Transvaal also . " (Burtt-Davy.) 
Vitis sp. (Vitaceae), 46787. Grape. Prom Mexico. 
Seeds collected by Mr. Wilson Popenoe and presented 
through Dr. H. J. Webber, Director, Citrus Experiment 
Station, University of California. "Totoloche. Collected 
at Mogone, Oaxaca, October 1, 1918. A wild grape ap- 
parently belonging to the Muscadine group or closely 
related to it. The plant is said to be abundant in 
this region, but I have not seen it. The fruit is 
brought into town by the Indian women from San Juan 
Guichicovi. This impresses me as the best grape I have 
ever seen in the tropical lowlands, and I believe it 
has value. At least it should be of importance in con- 
nection with the development of a grape for cultiva- 
tion in the tropics. It is vastly superior to V. earibaea, 
the berries being of much larger size and better fla- 
vor. The bunches are usually small and rather loose, 
but sometimes contain as many as fifty berries and
