in a remarkable degree the bitter and aromatic principles of the genus ; 
an infusion of it may be employed with benefit as a tonic and stomachic 
treatment during convalescence after marsh fevers ; also the powder as 
an anthelmintic remedy, especially for children, as observed by Welwitsch 
with good results during his stay in Huilla.

MossAMEDES.—A remarkably ornamental herb, apparently annual, 
with the habit of a Cineraria though with different style-branches ; 
stems much branched from the base, decumbent, at length as well as 
the branchlets ascending ; leaves opposite or rarely the upper ones 
alternate, glossy-green in the living state; ray-florets uniseriate, 
ligulate, tridentate at the apex, female, fertile, as well as the disk- 
florets very bright yellow shining subscarious and persistent ; corolla 
of the disk-florets pilosulous, with reflected lobes ; anthers ecaudate ; 
filaments enlarged a little below the apex with a waxy orange-coloured 
gland ; style-branches elongated, subclavate-thickened, densely puberu- 
lous ; achene elongate-obovoid, somewhat compressed, more or less 
covered with rather rigid hairs, with the marginal ribs rather acute 
and those on the faces obtuse, and with oily glands within the margin 
of the lateral ribs ; pappus biseriate, the outer row short and often 
but little developed, the setz of the inner row scabrid, unequal in 
length, rather rigid, straight, and persistent. 
MossaMEDES.—At the gneiss rocks by the upper banks of the river 
Bero, not plentiful ; fl. and fr. July 1859. No. 3999. 
I follow Oliver in referring this plant to Engleria, and the generic 
character must be modified accordingly ; but I cannot regard it as the 
same species as the Hereroland EL. africana, or even a variety of it. 
It differs from the latter in the following characters: the capitula 
are heterogamous and radiate, the achenes are not narrowly winged, 
the leaves are ovate-cordiform not attenuate at the base into the 
petiole, and the plant does not appear to be perennial.

A shrub, in habit almost lke the shrubby Conyzee ; stems 
crowded, slender, straight, reddish, beset with abundant lenticels ; 
branches patent, tomentose ; felt pallid; leaves alternate, ovate or 
elliptical, pointed and often acuminate at the apex, contracted 
often abruptly so at the base, membranous-herbaceous, yellowish- 
green above, rather paler beneath, clothed with short curly pale 
hairs on both faces denser and felted beneath, toothed or repand 
or nearly entire, triplinerved and penniveined, 11 to 4 in. long
