Castanea crenata (Fagaceae), 45337. Chestnut. From 
Bell, Maryland. Presented by Dr. W. Van Fleet, of this 
Bureau. Bell No. 4. Fourth generation, by selection. 
The trees have very much the same habit as S. P. I. 
No. 45334, 45335 and 45336, and the nuts are about 
the same size-very large. The nuts have good eating 
qualities, and are better than those of the numbers 
referred to above. This number is eminently worthy of 
propagation and dissemination. 
Chayota edulis (Cucurbitaceae) , 45540. Chayote. From 
Guatemala. Collected by Mr. Wilson Popenoe, Agricul- 
tural Explorer for this Department. "(No. 197a. Gua- 
temala, Guatemala, November 7, 1917.) Guisquil de Santa 
Maria. Locally considered one of the very best vari- 
eties. It is a short, broad fruit., compressed on the 
sides, and weighing . from 12 ounces to a pound. The 
surface is smooth, free from corrugations, pale to 
bright green in color. Green-fruited guisquiles are 
considered by the Guatemalans, to have more flavor than 
the white-fruited varieties. All smooth, small to 
medium- sized guisquiles are called peraleros; the spiny 
or rough fruits are termed simply gulsquil, in most 
instances . Occasionally they have distinguishing names , 
such as guisquil de Santa Maria. " (Popenoe. )
