Colour white or pinkish in young plants, and changing in ma- 
turity and age to yellow-ferruginous or deep fulvous *. Spots 
or tufts very irregular, often so confluent as to nearly cover the 
inferior surface of the leaf, robust, grumous, sub-immersed, 
which is ascertained by examining the upper surface of the leaf, 
rather than by the aspect of the plant. Tubes very beautiful, 
and unlike those of any other known species, dividing towards 
the summit into two, three, or four sub-patent, short branches, 
as thick as the rest of the tube, and each clustered with several 
globular, sessile heads, or perhaps more properly lobes. This 
species, which is far from being of frequent occurrence, is at ma- 
turity in the summer months. The only spot in which I have 
found it in this country, is by the river side half way between 
Lasswade and Roslin. 
Erineum hetulcB, De Cand,

E. epi- rare hypophyllum late inaequaliter effusum sanguineum, 
tubis multiformibus turbinatis, clavatis vel capitatis, apicibus 
saepe truncatis. — Gr. 
Erineum betulae, De Cand. Syn. FI, Gall. p. 15.

E. betulinum pertinet.) 
Hab. In foliis Betulae albae ; vere et aestate. 
This elegant species is so remarkable on account of its splen- 
did sanguineous or purple colour, that it must attract the atten- 
tion of the most careless observer. Another species, however, 
seems to have been confounded with it by Albertini and 
* Dr Hooker has mistaken the colour of this plant in calling it nearly scarlet.
