of BuiBEL, Meth. p. 76, which was found, in 1806, near 
Eome, and has since been detected in Switzerland. 
Upon an accurate examination, essential differences are 
perceived ; the leaves of G. campestris are much broader 
than those of our plant, and the piliferous terminations 
much shorter; the teeth of the former are rather long, 
and are " pretty regularly cleft for nearly half the way 
down from the apex in the latter they are short, never 
cleft, but perforated, or entire. In Mr Burchell's plant, 
the seta is so much exserted, as to convey the base of the 
capsule considerably above the diaphanous points of the 
leaves ; in ours, the seta is so short, that the capsule rarely 
rises above them, but more commonly the diaphanous 
points are on a level with the mouth of the capsule. 
With regard to Campylopus lamgaius^ it would not be 
easy to determine, from Brtdel's character, its precise re- 
lation to our plant, or whether indeed it be the same ; in 
many points they appear to agree ; but " pedunculis suh- 
arcuatis^'' and '^Jhlia erecta^'' render the identity very sus- 
picious, andj if his character be correct, must keep it dis- 
tinct. 
I liave received from Mr Aenott a plant, which he ob- 
tained from the Herbarium of Palisot de Be.iuvois, 
marked Grhmma obtusa ? or G, Don'iana .^^ It is certainly 
neither species, but accords more nearly with G. leucoplKzu ^ 
except in the teeth, which bear a greater resemblance to 
those of G. campestris^ and are like them frequently divid- 
ed almost half way down from the apex; in being rather 
more branched, and having the seta somewhat longer than 
in our plant ; so that, after all, it may be said to be inter- 
mediate between G. campestris and leucopha^a. 
Before the capsules arrive at maturity, the leaves of 
G. leucopluea gradually assume a blackish hue; wliich, 
contrasted with the hoariness arising from the long silvery
