72 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Algodon de yuca. See Gossypium janiphaefolium. 
Algodon rojo. See Gossypium barbadense. 
Said to be the variety which has been described botanically as Gossypium — 
purpurascens. 
Algodon yuca. See Gossypium barbadense. 
Said by Maza to be the variety described by Bello as Gossypiiwn janiphaefolium. 
Algodonecillo. See Anguria plumieriana and Asclepias curassavicd. 
Alilaila. 
A tree from all parts of the island: height, 35 to 40 feet (11 or 12 meters); 
diameter, 5 to 6 inches (12 to 15 centimeters). Wood pinkish, rather hard; spe- 
cific gravity, 0.803; used’in making agricultural implements. (Exp. 1857.) 
This is probably the same as “‘ llaila.’’ a name applied to Melia azedarach. 
Aljonjoli. See Sesamum orientale. 
Allamanda cathartica. Canario. 
Family Apocynaceae; an ornamental shrub or small tree introduced from 
South America. (Stahl, 6: 67.) 
Alligator apple. See Anona palustris. 
Alligator pear. See Persea gratissima., 
Allium cepa. ONION. CEBOLLA. _ 
Onions are occasionally cultivated in gardens, but the market supply is 
imported. An American correspondent states that only the Bermuda variety 
does well. The growing of Bermuda onions is one of the openings suggested for 
export gardening in Porto Rico and commercial experiments will probably be 
tried. The seed from Bermuda onions is all grown in Teneriffe. 
Allium sativum. Garuic. <AJOo. 
Allophylus occidentalis. QUIEBRA HACHAS. 
An indigenous tree of the family Sapindaceae. (Stahl, 2: 159, as Schmidelia 
occidentalis. ) 
Alloplectus ambiguus. : 
Family Gesneriaceae; a new species to replace the Alloplectus cristatus, which 
does not represent the genuine species of that name. Two varieties, chlorose- 
palus and erythrosepalus, are also named and reported from numerous localities. 
(Urban, Symb. 1: 408.) 
Alloplectus cristatus. TIBEY DE CRESTA. 
Family Gesneriaceae; a rather fleshy herb covered with a reddish pubescence; 
grows adhering to rocks in the higher mountains, flowering in summer. Urban 
includes this under his A. ambiguus. (Stahl. 6: 261.) 
Allspice. 
The occurrence of the true allspice, Pimenta officinalis, in Porto Rico has not 
been established, and the reports of Hill and others are probably to be taken as 
applying to Amomis caryophyllata, the tree yielding the oil of bay used in com- 
pounding bay rum. 


Almacigo. See Bursera simaruba. 
In Spain this name is applied to the true mastic tree, Pistacia lentiseus. 
Almacigo blanco. 
A tree from all parts of the island; height, 45 to 50 feet (14 to 15 meters); 
diameter, 12 to 15 inches (30 to 37 centimeters). Wood light-colored, soft; specific 
gravity, 0.271; not used. (Exp. 1857.)
