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. flava from Arabia and Eritrea (Schwein- 
Jurth), Species have been founded on the degree of denseness of the inflorescence, and 
the distance (4-2 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. J 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, flava 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 2 in. The indumentum of the calyx is that of J. flava (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 ¢ in. long, spikes dense 
(in one case going off into a close compound panicle). ; 
(4) Schweinfurth, 256, from Monnt 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. flava,
