The genus Dissotis, chiefly differing from Osbeckia by the very 
long connectivum and dissimilar anthers, was established by. 
Mr. Bentham on a Sierra Leone plant, the Osbeckia grandifiora, 
Sm., and the Osbeckia Senegambiensis ? of Guill. and Perott., of 
which a specimen in my herbarium from Heudelot, Mr. Bentham 
observes, is apparently the same. Our present species is very 
different from that in the form of the leaves and of the scales, or 
tubercles (as they may rather be called in this instance), of the 
tube of the calyx; the whole plant, too, is much more villous, 
and the root is in no way tuberous. 
Descr. Root subrepent, perennial ?, sending out copious black 
fibres. Stem one to two feet and more high, herbaceous, clothed 
as is the foliage, with long, villous, spreading hairs, in the native 
dried specimens having a purplish cast upon them, obtusely four- 
angular: dranches copious, more acutely four-angled. Leaves 
two and a half to three and a half inches long, shortly petiolate, 
lanceolate, three- to five-nerved, somewhat rigid, quite entire. 
Flowers solitary, terminal, smaller than in Dissotis grandiftora. 
Petals purple-rose. Oalye short, urceolate, clothed with tuber- 
culiform, clavate, spreading scales, each terminated with a pencil 
of long purplish hairs or sete; dimé of five, spreading segments, 
each with a gland at the point. Disc of the ovary conical, five- 
angled, with a few hairs on the angles, and a long tuft of hairs 
surrounding the style. Stamens ten, alternately small, the lesser 
ones with a very short connectivum, the larger ones with a very 
long curved one, bearing the large, purple, falcate anther, which 
opens with one pore at its summit.

to be appointed, and Mr. Gustave Mann, one of the very intelligent Hanoverian 
gardeners of the Royal Gardens of Kew, will sail on the 24th of this month 
for Lagos, where preparations are making for his ascent of the Quorra to Rabba, 
where Dr. Baikie awaits his arrival.
