Berberissp. (Berberidaceae) , 54269 , Barberry. Prom 
Ecuador. Collected by Mr. Wilson Popenoe, agri- 
cultural explorer. "(No. 622. Hacienda La Esperanza , 
near El Angel, Province of Carchi . ) 'Espino. ' Plants 
collected at an altitude of about 11,500 feet. This 
is one of the handsomest of the wild barberries 
which I have seen in Ecuador. It makes an arbo- 
rescent shrub up to 10 or 12 feet high, and has 
large , glossy , stiff, dark green leaves. The orange- 
yellow flowers, are produced in clusters about 3 
inches long, and half an inch broad. They are fol- 
lowed by oval, blue-black fruits. The species is 
worthy of a trial as an ornamental." (Popenoe.)' 
Dioscorea latifolia (Dioscoreaceae) , 53925. Acoro 
yam. Prom Buenos Aires , Argentina'. Tubers presented 
by Mr, D. S. Bullock, agricultural trade commis- 
sioner, U. S. Department of Agriculture, American 
Embassy. "'Papa de Aire en Parral ' (climbing air- 
potato." (Bullock.) 
"A yam which produces its crop of edible tu- 
bers along the vine, in the axils of the leaves, 
instead of underground . According to Mr. I. H. Bur- 
kill, it is of African origin and is called Acorn. 
Mr. Burkill states that it is very closely allied 
to Dioscorea bulbifera. The vine is round stemmed and 
the leaves heart shaped. The variety is not a very 
strong grower. The tubers are angular, brownish 
gray, thin but tough skinned, and in form resemble 
the liver of fowl -whence arises the name 'turkey- 
liver yam' by which the variety is known' in 
some parts of Brazil. The tubers weigh from a 
fraction of an ounce to as much as a pound each, 
depending upon age and the condition of growth; 
they keep exceedingly well. The quality of the 
tubers is fair when they are properly prepared for 
the table. The cooked tubers are rather firm, but 
toealy. Boiled in the skin, the yellowish flesh is 
of unpleasantly strong flavor,. but when the tubers 
are pared, cut into pieces, and boiled, the objec- 
tionable quality is removed. The boiled yam is 
also very good when slightly fried." (R. A.Young.)
