“Bruchia Drummondi, Hpe. in Sched,” is one of the synonyms 
cited by Jeger for “ B. drevipes Hook.” (Musci Cleist. 36, 1869). 
He limited this name entirely to the American species, and recog- 
nized the African as B. elegans (Hsch.) citing “ B. brevipes Hook. 
€ parte” as one of its synonyms. The American specimens should 
never be cited as B. érevipes Hook., but as B. brevipes Hooker 
and Wilson. Miiller in his Synopsis Musc. 1: 18, 1849, cites B. , 
brevipes Hook. (B. elegans Hsch.) correctly, and limits it exclu- — 
sively to the African species, as we maintain it should be. 
10. BRUCHIA RAVENELIU Wils. 
Bruchia Ravenelii Wilson in Sull. Mosses U. S. 17 (1 856). 
Icones Musc. 26, ¢. 76 ( 1864). Austin Bull. Torr. Club, 6: 144 
(1877). 
In Sullivant’s Herbarium are preserved the specimens from 
which the original description by Sullivant was drawn and the 
drawings from which the plate in the Icones (Icon. Musc. 26% 16 
1864) was engraved. They are labelled in the handwriting of 
Lesquereux “ Bruchia Ravenelii Wils. mss. from Ravenel to Les- 
quereux,” and all the characters but one agree with the drawings 
and require no explanations. The spores are figured and described | 
as “ papillose,’ but they are more properly reticulate, with con- 
fluent ridges, forming a honey-combed surface, which is distinctly ; 
hexagonally indented, the ridges appearing on the edges as Sulli- 
vant has figured them, but not so on the surface. They are small 
.027—.032 mm. and it is only with a magnification of 400 diame- 
ters that this can be distinctly seen. The stomata too are worthy 
of description, being slightly immersed, not very distinct, with the : 
surrounding cells radiating and covering the outlines of the guard 
cells. 
Specimens in Austin’s Herbarium, sent to him by T. P. James <3 
collected on the Santee Canal by Ravenel, from the same locality 
as the type, show also the same characters. He also had spect 
_ mens from Aiken and the seaboard in South Carolina, from Rave" mS 
nel, and some from Mobile, Alabama, collected by Charles Mohr. — ay
