160 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
this purpose the crop is cut while in flower, dried, made into bundles, and soaked 
in water for fifteen to twenty days. It is then possible to wash out a strong, 
silky fiber known in commerce as Rozelle hemp, considered by some to be the 
equal of jute, although little or none is exported to Europe. The natives use it 
mostly for cordage and coarser textile purposes. The seeds are employed in vari- 
ous medicinal decoctions and compounds on account of supposed demulecent, diu- 
retic, and tonic properties, and the calices are also made into a refreshing acid 
drink for fever patients and convalescents. 
The calices and young capsules nay be preserved by drying, and in this condi- 
tion are sometimes met with in tropical markets. The leaves are also an ingredient 
in certain dishes and the seeds are fed to cattle. Analyses show considerable 
quantities of tartaric and malic acid, but no citric, and the Jamaica sorrel thus 
supplements the lime in the direction of the qualities of our temperate fruits. 
It is becoming increasingly popular with the people of Florida, and is now com- 
monly cultivated in the southern part of that State. Americans in Porto Rico 
would do well to become acquainted with it. The species has been reported by 
Bello with the above native name as growing in country districts in the western 
part of the island, but is probably to be found occasion: lly elsewhere. Also called 
*aleluya roja de Guinea” and “ agrio de Guinea.’
