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 jiowder 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 Cineniria 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 setEe of the inner ix)w 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 Engler/((, and the generic 

 character must be modified accordingly ; but I cannot regard it as the 

 same species as the Hereroland E. </fricun<(, 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.

 crowded, slender, straight, reddish, beset with abundant lenticels ; 

 branches patent, tomentose ; felt pallid ; leaves alternate, ovate oi' 

 elliptical, pointed and often acuminate at the apex, contracted 

 often abruptly so at the base, membranous-herbaceous, yellow-ish-

 haii-s on both faces denser and felted beneath, toothed or repand 

 or nearly entii'e, triplinerved and penniveined, 1^ to 4 in. long
