Mr Greville on the Genus Ermeum. 75 
slightly immersed, and rather tufted. Spots or tufts roundish, 
sometimes confluent. Tubes linear, slender, somewhat rigid, sub- 
cylindrical, bent, with the apex incurved, and rarely sub-incras- 
sated : in some of the tubes are occasionally appearances of septa, 
but their existence is very doubtful. There can be no doubt of 
this being a true Erineum^ although, as De Candolle observes, 
it may be less understood than its congeners. In the summer 
months, this species is not uncommon on the Continent, but in 
this country it has not yet been discovered.

At first whitish, afterwards pink, lastly reddish and sub-fer- 
ruginous. Spots, numerous, tufted, roundish, or sub-angular, 
sometimes confluent. Tubes, very long, linear, flexuose, having 
often a genxculated appearance, flaccid, weak, apex rounded. 
A fine species, confined to the inferior surface of the leaf, and 
tolerably abundant on the Continent during the summer months.

A white plush-like down is the first appearance of this plant, 
which, as it advances to maturity, becomes sub-tomentose, and 
of a pinkish or dirty- white hue. Tubes, long, cylindrical, dia- 
phanous, sub-erect, and gradually attenuated. The veins of the 
leaf, at that part where the plant is situated, are considerably 
thickened, which gives it a solid and dense aspect, and, from 
being confined betwixt the parallel lateral veins, it has in gene- 
ral the figure of an oblong square. This species is rather un^ 
frequent : it has been found in France, but not published ; and 
last summer I met with it on a walnut-tree, close to the house, 
at Braid Hermitage, near Edinburgh.
