Through the courtesy of the authorities at the Berlin 
Museum I have been able to see the type specimen of this 
moss from Muller’s herbarium. This is labelled 4 Prov. 
Cochabamba, prope Choquecamata (Germain, Junio 1899).’ 
An examination of the moss showed that undoubtedly the 
stem-leaves have been wrongly described. The margin in 
the upper part of the leaf is not entire, but distinctly denticu- 
late as in typical vS. erythrodontus . Sometimes, through 
erosion, the teeth tend to become obsolete, but all the younger 
leaves, and most of the old ones, show the characteristic 
denticulate limb of S', erythrodontus. In all other characters, 
too, as might be expected from Muller’s diagnosis, the 
Bolivian plant agrees perfectly with S', erythrodontus , so that 
the name S', holivianus may be safely referred as a synonym 
to the present species. 
Through the kindness of Mrs. Britton I have received 
a specimen (now in the Kew Herbarium) of a moss labelled 
‘S', bolivianos , C. Mull. Yungas(coll. Pierre Jay, July 1893).’ 
This also shows all the characters of S. erythrodontus , the 
stem-leaves being distinctly denticulate. The specimens 
have, however, rather an abnormal appearance ; the leaves 
are very much twisted, and remain so in the wet state ; in 
fact, the leaves show scarcely any signs of reviving after 
prolonged soaking in water. The leaves are also very cadu- 
cous, separating from the stem and falling off entire on the 
plants being handled. All the specimens in fact have the 
look of plants which have grown under unfavourable con- 
ditions, and their appearance suggests the idea that they have 
been scorched by excessive heat. 
From the two examples quoted above we can now extend
