CARYOCAR VILLOSA. (Caryocaraceae . ) 3X204. Seeds from 
Para, 'Brazil. Presented "by Mr. Walter Fischer, acting direct- 
or, Campo de -Cultura Experimental Paraense. "The piquia is 
one of the forest trees of this vicinity that is prized for 
its lumber. The wood is extremely hard and strong, so strong 
in fact that the word piquia is almost symbolic for strength} 
it is white and close grained. I have seen hut one tree that 
stood in the open. In fruit with nearly all of its leaves 
shed, it resembled one of our black walnuts in the fall of 
the year. The fruit is boiled before eating. After peeling 
off the thick rind there remains a fatty layer of one half 
inch thickness enclosing a rather spiny seed as large as a 
walnut in the hull. It is this fatty layer which is eaten 
boiled, while the kernel of the seed is eaten raw." (Fisch-
