Socotra. On the plains. B.C.S. n. 358. 



Distrib. Endemic. 



Another characteristic, hoary and woody, intricately-branched plant of the 

 plains, and belonging in this genus to the section Gendarussa, which includes 

 shrubby plants with small spicate subsessile flowers and minute bracts and 

 bracteoles. With species in this section its alliances are south African. J. 

 incana, T. Anders, (in Journ. Linn. Soc. vii. (1864) 42), which is Adhatoda incana, 

 Nees ab. Esenb. (in DC. Prod. xi. 393), is its nearest affinity. But though in 

 habit and foliage almost identical, the plants are easily distinguished, as the 

 south African one has large solitary flowers and large capsules.

A genus of Justiciew with two-celled anthers, the lobes of which are slightly 

 unequal and discrete, the upper one being sometimes almost muticous, but is 

 commonly mucronate, whilst the lower, which is always spurred, has at times 

 the spur much reduced. Its other prominent features are the thread-like 

 bracts, bracteole, and calyx-segments, which both in flower and fruit radiate 

 from the clustered inflorescence, and the form of the corolla. 



The genus has some resemblances with members of the group to which 

 Ballochia belongs, but the antherine characters exclude it, and relegate it to the 

 vicinity of Justicia itself. With some shrubby members of this genus it agrees 

 in habit, but the mucronate upper anther-lobe, and the absence of all palate on 

 the corolla, as well as the general form of this latter, are diagnostic. From 

 Adhatoda, so nearly allied to Justicia, similar characters separate it, and whilst 

 its habit is that of Anisotes, presently to be referred to, it wants the long anterior 

 corolline lip of that genus, and has quite a different inflorescence. Isoglosm is
