and wrote on the packet ‘good species,” but the description and 
plate in the Supplement to the Icones were drawn from Ravenel’s 
specimens, as his herbarium shows. He cites the following 
synonyms and localities: 
Sporledera Beyrichiana Hampe, Linn. 20: 279 (1837). 
Phascum Beyrichianum Schwegr. Suppl. 4: ¢. 307 (1842). 
Bruchia Beyrichiana Miill. Bot. Zeit. 5: 99 (1847). 
Hab. first found near Baltimore, by Beyrich; Santee Canal, 
Ravenel ; Burlington, New Jersey, James; North Illinois, Dr. G. 
Vasey, 
All of the specimens above cited, except those collected by 
Ravenel, are immature, but a careful comparison one with another 
has enabled me, from leaf characters and imperfect fruiting char- 
acters, to say that Sullivant was nearer right in his first opinion 
than in his last, and that most of the description and all of table 
fifteen in the Icones Supplement were drawn from the only perfect 
specimens he had, those collected by Ravenel; hence these must 
be considered the types of Bruchia Beyrichiana Sull. They prove 
also that 2B. Beyrichiana Sull., is quite distinct from Sporledera 
Beyrichiana Hampe. When compared with Hampe’s original, 
Sullivant’s specimens are taller and more densely leafy, the stems 
quite developed, 2 mm. long, several with the leaves and capsules 
included reaching 4-5 mm. Hampe’s are almost acaulescent, 
With the leaves crowded at the base, the whole plant not attaining 
2mm. in height. The leaves also show a marked difference ; 
Sullivant’s are falcate-secund when dry, erect when moist, with a 
long slender tip entire below, but distinctly serrate at apex, often 
6-8 of €qual length, crowded at the apex of the stem; Hampe’s 
are flexuous, recurved and twisted, with a longer, broader base 
and a stouter point, which when highly magnified shows the short 
transverse walls to be thickened, giving the back of the leaf the 
appearance of being papillose, whereas Sullivant’s are often per- 
fectly Smooth, with the same magnification. 
Both have erect pedicels, but Sullivant’s are exserted, whereas 
Hampe’s are immersed, and the calyptra in the latter is larger and 
More lobed. Certainly these two are not the same species.
