270 FLORA: NIGRITIANA. 
I have separated this from K. maxima, on the grounds of its 
constantly smaller size, and the few leaflets. 
1. Tribulus cistoides, Linn,— Sierra Leone? Don. 
This is one of the very few plants common to the West 
Indies and Pacific Islands, being found in Oahu. It varies 
much in the size of the fruit, which in these W. African speci- 
mens is particularly large. 
The Tribulus terrestris is a native both of Senegal and 
Guinea. 
1. Zygophyllum simplex, Linn.—Benguela, Dr. Curror. 
A plant common to the shores of the Red Sea, the banks of 
the Nile, and the Cape de Verd Islands, but not that I am 
aware of to any other part of the W. coast of Africa, except 
Benguela. 
Fagonia Arabica, a native of Arabia, as well as of N. Eastern 
Africa, is also a Senegal plant. 
1. Balanites Ayyptiaca,* Del. Fl. Æg. p. 77, t. 28, f. l.— 
Senegal, Sierra Leone, Whitfield. 
Also a native of Abyssinia, and a variety of it, by €— 
considered as a distinct species, extends to the dry plains of 
Bengal. 
XXXVII. ZANTHOXYLEX. 
l. Zanthoxylum rubescens; Planch. in. Herb. Hook.; rams 
aculeatis, foliolis circa 11 suboppositis ovali-oblongis longe 
acuminatis basi acutis. érebre. pellucido-punctatis petiolo acu- 
leato supra canaliculato, floribus diclinis, masculis paniculatis 
parvis tetrameris.— Cape Coast, Vogel. 
Frutex orgyalis, ramulis rubentibus, aculeis validis conicis recte 
reflexis v. recurvis. Foliorum petiolus 8-9-pollicaris. Foliola 
2-8 poll. longa, pollicem lata, glabra, membranacea. Pani- 
cula ampla, bis terve racemoso-ramosa, ebracteata. Flores m 
* Brown removes Balanites from Zygophyllem, but as I am not aware 
that he has published his views of its real affinities, and as, at any rate; 
it is in some measure related to Zygophyllee, I have left it here at the end 
of the Order.—(G. B.)
