Gossypium barbadense. CoTron, ALGODON, 
Cotton is not raised in Porto Rico as a commercial crop, and indeed none is to 
be seen about the country except now and then a shrub in a dooryard, 
The cotton plant is also one of many, of tropical origin, which have been 
selected and improved in subtropical or temperate regions and which tend to 
return to their original habits when taken back to the more humid tropics. The 
cottons of tropical countries, of which there are several species, are perennials, 
and scarcely begin to bear during a period sufficient for ripening a crop in the 
Southern States. There is, accordingly, little fear that any tropical country will 
successfully compete with warm temperate regions like Egypt and our Southern 
States, where the crop can be brought to early and even maturity so that the 
the necessary labor can be applied with advantage and economy. 
The name *‘algodon rojo”’ (red cotton) is said to be the variety described 
botanically as Gossypium purpurascens. 
Gossypium janiphaefolium. ALGODON DE YUCA. 
A species of cotton described by Bello from the vicinity of Cabo Rojo, called
