128 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Cosmos caudatus. MARGARITA. 
Family Compositae; a common weed in open places. Near Toa Baja this was 
called ‘‘ claveles,’’ and at Coamo “‘ piquete.’’ (Stahl, 5: 130.) 
Cotona. 
A tree from all parts of the island: height. 25 to 30 feet (7 to 9 meters); diam-— 
eter, 8 to 10 inches (20 to 25 centimeters). Wood hard, yellow; specific gravity, 
1.194; used in building country houses. (Exp. 1857.) 
Captain Hansard gives a specific gravity of 0.90 for this tree. 
Cotorra. 
A wild tree, produced in abundance over the entire island, 30 to 35 feet (9 to 11 
meters) high, with a trunk 8 to 10 inches (20 to 25 centimeters) in diameter. It 
furnishes a moderately hard wood, canary-yellow in color, breaking with a verti- 
cal fracture. Used in the framework of country houses, for fences and other uses 
of this class. (Grosourdy, 2: 378.)

In his account of this palm Mr. Hill has probably confused the royal palm with 
the llume. There is nothing to indicate reference to the small, spiny palm to 
which the name is in reality applied, at least in the vicinity of Vega Baja. 
Cracca aniloides. ANIL FALSO. 
Family Viciaceae; an herbaceous annual, 40 centimeters high; flowers in 
November; reported from the beach of the east coast. (Stahl, 3: 28, as Tephrosia 
aniloides. ) 
Cracca cinerea. ANIL CENIZO. 
A woody herb, 40 centimeters high, found along the beach; flowers all the year. 
Common throughout tropical America. Specimens collected along the seashore 
at Catano, where the plant is called simply anil, and is used as a blue dye for 
cloth. (Stahl, 3: 26, as Tephrosia cinerea.) 
Cracca leptostachya. ANIL RACIMILLO. 
An herbaceous annual, 50 centimeters high, growing along the sandy shore, 
between Arecibo and Aguadilla. Common to the tropics of America and Africa. 
(Stahl, 3: 27, as Tephrosia leptostachya.) 
Craceca purpurea. ANIL RACIMILLO. 
Craniolaria annua. ESCORZONERA. 
Family Martyniaceae; an herb a meter high. The large fleshy roots are used 
as a substitute for the European ‘‘escorzonera.’’ (Stahl, 6: 264.) 
Crape myrtle. See Lagerstroemia indica. 
Cremanium amygdalinum. See Tamoneu integrifolia.
