PULMONARIA ANGUSTIFOLIA. 381 
erect form of Lastrea, furnished with a few broad pallid scales 
on its stipes, and a prostrate, slowly creeping caudex, which ought 
not to be confounded with any form of L. dilatata.—T. M. 
Pulmonaria angustifolia. 
An Honourable Correspondent (the Hon. Fox Strangways) has 
very recently been so obliging and courteous as to point out to 
us the distinction between P. officinalis and P. angustifolia. To 
the same source we are indebted for a specimen of the latter. 
Mr. F. Strangways’s-object is to state that it is clearly “ distin- 
guishable as a species” from the former, and as a proof sub- 
mits both a drawing of the two plants and a living example of 
the latter-mentioned. Continental botanists appear to have no 
doubt about their specific difference. The officinal plant, which 
is common in gardens, is described as having cordate-ovate radi- 
cal leaves, with ovate stem-leaves. The narrow-leaved and rarer 
species, P. angustifolia, has ovate-lanceolate, elongate, rough- 
haired radical leaves, and lanceolate and pointed stem-leaves. 
The stem in the latter is almost simple, and nearly twice the 
length of that of the former. These distinctive characters are 
from a German flora. Sir James E. Smith appears to have un- 
derstood these plants as specifically distinct. He says (KE. Flora, 
p- 262) P. angustifolia is about twice as tall as the former (P. 
officinalis), from which it differs in the lanceolate shape of its 
leaves, especially the radical ones, which are a span in length, 
tapering and not spotted. He previously describes the root- 
leaves of the former as ovate, hairy, mostly speckled with white 
on the upper side, whence they have been thought to resemble 
the human lungs, etc. 
In Cosson and Germain’s ‘ Flore des Environs de Paris’ there 
are three varieties of P. angustifolia, described as below :— 
Var. a, vulgaris ; root-leaves lanceolate, very narrow, usually 
not spotted. 
Var. 8, longifolia; root-leaves broadly lanceolate, gradually 
attenuated (tapering) below, spotted with white, often longer 
than the stem. 
Var. y, latifolia ; root-leaves broad, ovate, abruptly tapering 
at the base, spotted with white, often shorter than the stem.
