Vahl describes, under the name Mimosa salinarum, a specimen collected 

 by von liohr in the Salt Ponds district of Jamaica, which, from the 

 description, is evidently Prosqpis jwZi^ora DC. 



"The pods are richly impregnated with a sticky astringent gum, which 

 may be easily extracted ; and would prove an excellent medicine, where 

 rough astringents are requisite " (Browne).

 Pinnse 2-4 cm. 1. ; leaflets oblong-linear, blunt ; veins slightly prominent.

The distilled flowers yield a delicious perfume. A tree gives 2 lbs. of 

 flowers, valued at 3d. to 4d. per lb. ; an acre in south Europe brings iu 

 £30 to £40. The gum is looked upon as good as, or better than, gum 

 arable (Watt). See also " Perfumery and Essential Oil Record," March, 

 1916. The wood is hard, heavy, and close-grained; used in India for 

 agricultural implements.]
