as to Bolus 11011 only. 
Var. B, komghensis (N. E. Br.); lateral and lower calyx-teeth deltoid- 
attenuate, not bristle-like, otherwise in appearance, structure and dimensions like 
the type.

The variety komghensis may prove to be distinct, as the locality is so widely 
different from that of the type, but the single dried specimen I have seen is 
so similar in all characters except the calyx-teeth, that I am inclined to think 
that the plant may have been an accidental introduction from the Transvaal, and 
the moister maritime climate may have influenced the development of the calyx- 
teeth. O. Wilmsii is quite distinct from the Indian 0. glabratus, Benth., of 
which Bentham considered it to be a variety. 
22. 0. inconcinnus (Briq. in Bull. Herb. Boiss. 2™ sér. iii, 991) ; 
branches with internodes }~1} in. long, minutely puberulous or 
glabrous ; leaves spreading ; petiole up to 5 lin. long; blade up to 
1} in. long and 2 in. broad, ovate, obtuse to acute, roundedly 
tapering at the base, crenately toothed, nearly or quite glabrous 
above, pubescent on the veins beneath; inflorescence up to 4 in. 
long; whorls at length distant, 6-flowered ; bracts very minute, 
ovate, apiculate, deciduous, purplish; pedicels 14-2 lin. long, 
shortly pubescent; calyx-tube nearly 1} lin. long, campanulate- 
tubular, minutely and thinly pilose or nearly glabrous, without 
evident nerves, purplish-violet; upper lobe or tooth rounded, 
3—{ lin. long; lateral and lower teeth 1—} lin. long, lanceolate- 
subulate ; corolla exserted about 24 lin. beyond the mouth of the 
calyx ; tube cylindric ; lips about 1} lin. long ; stamens reaching 
to the mouth of the corolla, but shorter than the lips. 
Eastern REGION: Natal ; hills near Camperdown, Wood, 4963. 
I doubt if this is distinct from 0. Wilmsii, Guerke. I have not seen it, and 
Mr. Wood informs me that no specimen of 4963 has been retained in the Natal 
_ Herbarium. 
23. 0. varians (N. E. Br.); stems probably several from the 
same rootstock, about 1 ft. high or less and } lin. thick, 4-angled, 
pilose-pubescent between the angles, with 3-4 pairs of short flower- 
less ascending branchlets shorter than to twice as long as the 
leaves from whose axils they arise ; leaves spreading ; petiole 4—} in. 
long, slender ; blade $—1 in. long, }-} in. broad, lanceolate or ovate- 
lanceolate, acute, cuneately acute at the base, rather finely serrate,
