spines being somewliat recurved. In a variety from Natal, wliicli I had named Kraussiana, the short 

 ^pines are still more recurved, the pod sometimes like th^t of A. Adansonii, but in other specimens more 

 deeply indented, and sometimes nearly glabrous, or narrower. The Indian form is in most respects like 

 the typical A. arabica, but more glabrous, the pod always hoary or white. The A. nilotica or A. vera, 



w 



from Egypt and Nubia^ is quite glabrous^ the pod green and usually very deeply indented, the one-seeded 

 orbicular articles resembling flat beads, connected by narrow isthmuses; but the indentations of the pod 

 are as inconstant as in A, macracantha ; and I have seen, in two or three other cases, one portion of tlic 

 pod as little indented as in A. Adansonii, and another portion of the same pod as deeply so as in 

 A. nilotica.

A, pseudo-arabica, Blume, of uncertain origin, is very imperfectly described by Miqucl, Fl. Ind. Bat. i. 

 part i. 8, from a very bad specimen, which he thinks may prove to be a variety of A. arabica, or of 



it

The great tubercular thickening of the pod over 6ach seed may not prove to be more constant than 

 the other variations in the pod of A. arabica, to which in that case this plant TVuuld be referred a« a 



variety.
