118 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
A specimen of citron was secured from a street vender in San Juan. He stated 
that considerable quantities are grown in the vicinity of Trujillo Alto, but there 
was no opportunity of investigating that locality. Large amounts of citron peel 
are imported into the United States from Mediterranean countries, notably from 
Corsica, and experiments in the culture of the trees are being made in Florida and 
California. The possibility of success in Porto Rico is worthy of investigation. 
Although none of the citrons now in commerce are grown in tropical countries, 
there are said to be varieties of excellent quality in Hindostan and the Malay 
Peninsula. The Porto Rican specimen observed was of medium size, but the skin 
was too thin and too loose in texture and apparently deficient in flavor. Some or 
all of these defects may, of course, be due to the absence of proper culture.
