VARIETIES. 
Pica-uncucha, S. P. I. No. 41120.—This yautia, received from 
Santa Ana, Peru, produces red-skinned tubers (fig. 14) of good shape 
which weigh from 4 to 8 ounces each. They are very acrid when raw 
and require thorough cooking, but the quality is very good. The 
Fic. 18.—A hamper of yautia tubers grown on rich hammock land in southern Florida. 
Potatoes planted on the same kind of land adjoining were more seriously injured 
than the yautias by frost. Flooding which killed potatoes did not appear to injure 
the yautias. (P26067EFS.) 
corms are not edible but are used for propagation. At Brooksville, 
Fla., where the variety has been tested in the field, the plants grow 
only 3 to 34 feet high, but several good tubers are borne in each hill. 
The Pica-uncucha deserves to be grown at least for home use wher- 
ever it will thrive. 
Malanga coloré, S. P. I. No, 34854.—This variety, received from 
Guadeloupe, West Indies, represents a dwarf type of rather long 
season yautias, of which the corms are eaten. As grown experiment- 
ally in Florida, the lateral tubers are too small for table use. The 
corms never grow to large size, and hence the yautias of this group 
are light producers. The flesh is yellowish or orange and usually of 
excellent quality, and varieties of this type are highly esteemed wher- 
ever grown in the West Indies. On account of their slow and rather 
weak growth it is not likely that they will prove adapted for com- 
mercial cultivation in this country, except possibly in southern
