dent then that the only specimens in Sullivant’s Herbarium from 
which he could have drawn the figures which were used in the 
Icones were those collected by Ravenel which Lesquereux and 
James say are the ones on which they founded Bruchia brevicollis. 
In order to determime if Ravenel’s specimens were sufficiently 
distinct from the type of Phascum flexuosum to maintain B. brev1- 
collis as a species, they were placed together and carefully com- 
pared. 
The best developed specimen of the type is almost an exact 
counterpart of one of Ravenel’s specimens. In both an occa- 
sional trace of roughness may be seen on the leaves, although 
Most of them are smooth, slender and subulate; the pedicels are 
the same in length and position, the capsules smaller, but the pro- 
portions of the neck, beak and sporange are the same.

On Page 279 of Linnzea, Hampe says, “‘ Die Capseln sind frei- 
lich nicht ausgebildet, aber doch die Form schon zu erkennen.” 
He describes the specimens as follows: 
“ Muscus flavescens, Phasco subulato simillimis, foliis inferioribus ex basi latiore 
Subulatis nervosis, perichztialibus latioribus et longioribus, complicatis integerrimis 
secundis vel flexuosis, Capsula oblonga erecta-pedunculata, calyptra campanulata 
eadem includente.” 
I have not seen Hampe’s own specimen of this species, but the 
On€ sent to Sullivant by him is too immature to show even the 
form of the capsule, for that had not begun to be formed, the 
calyptra and pedicel being still immersed in the leaves. In fact, 
the plants had only perfected the calyptras, and are still too young 
to say whether the pedicels would be erect or curved, though 
there is a slight twist in the seta just below the calyptra. The 
other characters have been described in the comparison with &. 
Seyrichiana Sull. given above. The following measurements are 
Placed on record as the earlier descriptions are all too indefinite.
