Jeger, in his Musci Cleistocarpi (1869), recognized two genera. 
I. Sporledera Hpe. (S. palustris, S. Beyrichiana, S. Ravenelit, 
and S. setifolia from North America, and three exotic species). 
II. Bruchia Schwegr. (B. brevipes, B. brevifolia, B. microcarpa, 
B. flexuosa and B. Bolanderi with four exotic species). 
He divided the genus Bruchia into two sections : 
A. Garckidium (B. brevifolia, B. brevipes and two exotic species). 
B. Eubruchia (B. flexuosa, B. microcarpa and B. Bolanderi with 
one of the European species). 
When Sullivant’s Mosses of the United States was published 
in 1856, he recognized five species in this genus: B. flexuosa, B. 
Beyrichiana, B. brevipes, B. brevifolia, and B. Ravenelii, with B. 
palustris under Pleuridinm. : 
In the Icones Muscorum (1864) he figured four of these: 2B. 
flexuosa, B. brevipes, B. brevifolia, and B. Ravenelit. Of B. Bey- 
richiana he secured an original specimen from Hampe, and states 
that this species is ‘‘an immature state of B. brevipes.” 
In the Supplement to the Icones (1874) he changed his mind 
about B. Beyrichiana, and figured it, not from the original spect” 
mens, however, but from those collected by Ravenel on the Santee 
Canal. He also added B. Bolanderi, making six species in all. 
Ten years later, in the Manual, Lesquereux and James recog 
nized fourteen species, including B. palustris, adding four of 
Austin’s species, B. Sudlivanti, B. Hallii, B. Donnellii, B. Texanas 
two of their own, B. drevicollis and B. curviseta, and a Chilian sp& 
cies which never should have been included, B. Hampean@ 
Miiller. 
Since then Prof. Eaton has described one new species, B. /omg* 
collis. Illustrations of most of these have been published. Plates 
of Austin’s four species have been drawn for this contribution 
from the original specimens in his herbarium. 2. curvisela L.& 
J. has not been figured, but it is very close to B. Zexana, and the 
type specimens in James’ Herbarium are not accessible. 
In this contribution we have limited the name B. flexuosa to the 
type species, reduced B. drevicollis to it, rejected B. Beyrichiana a 
a mixed and uncertain species, limited the name B. brevipes to the 
African species and replaced it for American specimens by ae 
Drummondii, discarded B. Hampeana,a Chilian species, maintane”
