Corchorus hirsutus. Matva Th DE LA PLAYA. 
Family Tiliaceae; a shrub 2 to 6 feet (0.6 to 2 meters) high, found along the sea- 
coast. A specimen collected at Santurce (no. 293), and there called ‘‘ cadillo,’’ 
agrees fairly well with a sheet from St. Croix in the National Herbarium, but is 
much less hirsute than material from other parts of the West Indies and South 
America. A variety, tortipes, was obtained by Sintenis at Aguadilla, who also 
secured the typical form at Guanica. (Stahl, 2: 117.) 
Corchorus hirtus. MAtva TR. 
A woody herb. (Stahl, 2: 115.)

used for tea. (Stahl, 2: 116.) 
Cordia. 
A large genus of boraginaceous trees yielding medicinal drugs, edible fruits, 
and yaluable timber. In the characters of habit, leaves, and inflorescence the 
species of Cordia are extremely diverse, and there also appears to be considerable 
confusion as to the identity of closely allied species.
