FLORULA ADENENS1S. 5 



In the Hookerian Herbarium there is a glabrous specimen of Cadaba 

 Indica, Lam., which, except by its having the pale-yellow flowers of that 

 species, I cannot distinguish from some broad-leaved herbaceous specimens 

 of C. longifolia from Aden. The normal states of C. longifolia and C. 

 Indica are, however, markedly different. 



3. Cap paris, Linn. 

 1. C. galeata (Fresen. in Mus. Senck. ii. p. 111). Fruticosa, glauca, 

 ramis diffusis, foliosis ; foliis petiolatis, ovatis, crassis, mucrone recurvo 

 uncinatis ; stipulis duabus, spinosis ; floribus solitariis, axillaribus ; 

 pedunculo foliis longiore, erecto, in fructu deflexo; sepalis 4, sepalo 

 maximo galeato ; petalis subrotundis, glabris ; staminibus numerosis ; 

 fructu baccato, pyriformi, angulato ; thecaphoro longo, pedunculum 

 aequante; seminibus reniformibus, testa Crustacea. — C. Murrayana, 

 Grah. Cat., et Wight, Icones, t. 379. C. cartilaginea, Dene, in Ann. 

 Sc. Nat. ser. 2. vol. iii. p. 273. C. uncinata, Edgew. in Journ. Soc. 

 Asiat. Bengal, xvi. p. 1213. 

 Hab. Aden, in rupibus (Edgew., Hook.fil. et T. ! T. Anders.). 

 Distr. In Arabia Petrsea! ^Egypto! Scinde! in ora occidentali pen- 



insulae Indise orientalis. 

 Frutex glaucus, ramis junioribus pulverulentis, stipulis aurantiacis unci- 

 natis. Folia cartilaginea, l£-2 unc. longa, 1-2 unc. lata; petiolus 

 foliis brevior. Petala et stamina alba, denique pallide purpurea aut 

 purpureo-rubra. Fructus maturus ruber, 8-10-costatus, 4 unc. longus, 

 H unc. latus. Stipes 2 unc. longus. 

 It is impossible to distinguish this plant by any essential characters from 

 states of that protean species Capparis spinosa, L. 



To Capparis spinosa I unite C. jEgyptiaca, Lam., C. herbacea, Willd., 

 C. ovata, Bieber, C. rupestris, Linn., C. obovata, Royle, C. ovata, Desf., 

 C. mucronifolia and C. parvifiora, Boiss., C. Sicula, Guss. In all of these 

 so-called species, and especially in C. herbacea and C. rupestris, spe- 

 cimens are constantly occurring in which the slightly recurved mucro of 

 the leaf, the large flowers with a more or less galeate sepal, large-angled 

 fruit, and the glaucous state of the wliole plant indicate an affinity to 

 C. galeata. As, however, some of the steps are wanting, I have for the 

 present kept C. galeata distinct from C. spinosa. 



4. Mjsbua, Forsk. 

 1. M. Thomsoni (T.Anders.). Virgata, glaberrima; foliis linearibus, 



oblongis, coriaceis, mucronatis, brevi-petiolatis ; floribus solitariis, 



pedunculatis ; calyce tubuloso, brevissime 4-partito ; fructu carnoso, 



stipitato, glabro, toruloso. 

 Hab. Aden (Hook.fil. et T. !). 

 Frutex glaberrimus, virgatus, foliosus, ramis paucissimis, cortice punctato. 



Folia in ramis floriferis fasciculata oblonga, in aliis alterna linearia. 



Theeaphorus pedunculo longior.
