The colour of the corolla is known to be yellow in J. plicata (the Upper Guinea 

 plant), in the more ovate-leaved Angola plant, in the Abyssinia (Eritrea) plant, and 

 in the Mozambique examples (including the Natal J. fasciata). The colour of the 

 corolla is not known to me in J. major and J. minor (Abyssinia) ; but the type 

 examples appear to me identical with the J. fiava from Arabia and Eritrea (Schwein- 

 furth). Species have been founded on the degree of denseness of the inflorescence, and 

 the distance (|— 2 in.) by which the lowest whorl of 6 (or fewer) flowers stands apart 

 from the next upper whorl. S. Moore says that "in this species there is considerable 

 diversity in the size and number of seeds on the same specimen " ; and Lindau 

 refers J. major to sect. Monechma, J. plicata to sect. Rostellaria. I remark on 

 these views that J. major and J. plicata look to me identical, and that the seeds are 

 most uniform in all the examples cited here. The most striking aberrations from the 

 typical J. fiava among the material above brought together are : 



(1) Hildebrandt, 1940, from Mombasa (and several similar examples from the same 

 neighbourhood) , published by Lindau as J. palustris, var. dispersa : this has ovate 

 leaves, 1 by § in. The indumentum of the calyx is that of J, fiava (not of 

 J. palustris). 



(2) Welwitsch, 5035, 5097, from Angola (and other examples from the same 

 locality), published by S. Moore as J. plicata^ var. ; this has ovate leaves, but is rather 

 larger than Hildebrandt, 1940. 



(3) Rowland\s Lagos plant, which has floral leaves up to f in. long, spikes dense 

 (in one case going ofi" into a close compound panicle). 



(4) Schweinfurth, 256, from Mount Erkowit, near Suakin, a small plant with 

 small leaves, and the spike much interrupted below (with, in fact, axillary clusters of 

 flowers). This may be a separable species ; but the fruit and seeds, the flower and 

 calyx-indumentum, are as in J. fiava. 



19. J. palustris, T. Anders. inJoum. Linn. Soc. vii. 38. Leaves up 

 to 6 J by 1 J in., oblong, tapering at either end ; petiole very short. Sepals 

 hispid, without minute moniliform hairs ; otherwise as J. fiava. — Zarb,
