Mr Greville on the Genus Erineum, 
Erineum iliclnum^ De Cand. 
Plate II. Fig. 5. 
E. hypophyllum tomentosum confluens rufo-aurantiacum, tubis 
longis linearibus flexuosis attenuatis. — Gr. 
Erineum ificinum, De Cand. Syn. FI. Gall. p. 15. 
Hab. In foliis Quercus ilicis, rarius 
Changing from a yellowish to a rich orange-brown ; tomert- 
tose, tufted, generally confluent, and preferring the margin of 
the leaf, which is frequently rolled in so as partly to conceal the 
plant. Tubes, long, flexuose, linear, atenuated and acute. 
They have sometimes the appearance of being irregularly di- 
vided by oblique lines, the nature of which I have not been able 
to ascertain. This is a very handsome and rare species, and 
only described, I believe, in the Syn, FI, Gall. It grows only 
on the lower surface of the leaf, and is in perfection in summer. 
Erineum clandestinum^ mihi. 
Plate 11. Fig. 8. 
E. hypophyllum albo-roseum confluens margine folii involuta 
obtectum, rare maculaeforme, tubis brevibus ovatis sub-capita- 
tis vel clavatis. 
Hab. In foliis Cratsegi oxyacanthse ; aestate. 
Changing from white or pale pink to an unequal ferruginous 
colour, which is darkest when the plant happens to occur in the 
form of spots, in the centre of the leaf ; it is in general confined 
Xo the margin, which is so completely rolled in, as to entirely 
conceal the plant. This is probably the reason why it has been 
so long overlooked ; to the eye even of a nice observer, it 
might pass as a receptacle of insects. The tubes are short, very 
simple, and often tinged with yellow. In spring and summer 
it is not unfrequent, particularly at Roslin, by the river side be- 
neath the Castle, and in similar situations. 
* The possession of this very rare species, with two others not hitherto de- 
scribed, I owe to the kindness of my acute botanical friend G. A. Walker Arnott, 
Esq. who received them in Paris from the Herbarium of the Baron Delessert, and 
divided them with me.
