 from Rumphius' figure and description {Herh. Amb. iii.

 pear, X.O Prosopis ; probably it may be referrible to some one 

 of those above described, but as I have not seen the speci- 

 mens, and the fruit is entirely unknown, I cannot venture to 

 place it anywhere.

extratropical S. Africa — This plant was placed by De 

 Candolle in Acacia, with a query whether it was not rather 

 a species of Prosopis. E. Meyer, who describes the pod 

 from Drege's specimens, says, " Legumen singulum vidi, 

 vetustate corruptum, de genere tamen omne dubium remo- 

 vens," and consequently retains it without doubt in Prosopis. 

 With this I cannot agree; as not only do the more pedicel- 

 late flowers, habit and foliage, remove it in appearance from 

 Prosopis, but the pod above described does not at all agree 

 with that of Prosojns, which is multilocular, indehiscent, and 

 does not separate from the sutures. The Elephantorrhiza
