120 MR. N. E. BROWN: A REVISION OF 
A Revision of the Genus Hypericophyllum, with Notes on 
certain allied Genera of Composite. By N. E. Browy, 
A.LS, 
[Read 20th June, 1901.] 
(PuateE 6.) 
Tue genus Hypericophyllum was founded by Steetz upon a 
remarkable plant (H. compositarum, Steetz) collected by Peters 
in Portuguese East Africa, which, owing to the want of sufficient 
material, has been the subject of considerable confusion, three 
other species having been mistaken for it, and a specimen of the 
true H. compositarum redescribed as a new species. Further, 
Bentham (Journ. Linn. Soc., Bot. xiii. (1873) p. 450, and in 
Bentham & Hooker, Genera Plantarum, ii. p. 397) united 
Hypericophyllum (together with Chetymenia, Hook. & Arn., 
and Espejoa, DC.) with the genus Jawmea, Pers., and thus the 
marked peculiarities of the genus have been lost sight of. For 
an examination of the Kew material demonstrates that the view 
taken by Bentham of the identity of these four genera is quite 
untenable, since they all possess characters that entitle them to 
rank as distinct from each other. The genus Hypericophyllum 
is certainly very distinct from Jawmea, not only in distribution, 
habit, and appearance, but by the presence of glands in its 
leaves and tissues, its flat receptacle, 4-5-angled achenes, and 
remarkable pappus, the hooked bristles of which appear to be 
unique in the Order. It is therefore proposed to restore this 
and the other three genera to their former generic rank, the 
following being a key to their distinctive characters :— 
Heads discoid or radiate, many-flowered ; 
receptacle conical; achenes linear- 
oblong, 10-ribbed, glabrous; pappus 
of straight, slightly flattened ciliate 
bristles, or of 1-38 minute sete or 
none ; corolla very much longer than 
the pappus; leaves fleshy, linear-sub- 
terete, without glands. — Shores of
