924 CHAETOPHORACEAE 
DeToni ; it is inconceivable that this slender, erect-branched form 
should have been so identified by any one familiar with Lyngbye’s 
work. 
Agardh quotes in the synonymy of this species, Batrachosper- 
mum Americanum Schweinitz. This was in all probability merely 
a manuscript name, but a specimen bearing this name in Schwein- 
itz’s hand in the Torrey herbarium is not Draparnaldia but Chaeto- 
phora incrassata ; it was so recognized by Bailey, who called it 
Chaetophora Schweinitsti (cf. Kitz. Tab. Phyc. 3: 6. 1853). 
DRAPARNALDIA SPINOSA Kitz. Phyc. Germ. 230. 1845; Spec. 
Ale 356. 1849; Tab. Phyc. 3: ۸ 73. f. z. 1853. Wolle, Bull. 
Torrey Club, 8: 40. 1881; F. W. Alg. 109. pl. 93. f. 1-8. 
1887. 
Wolle’s figures appear to represent a plant different from any 
known to us. Whether his specimens were correctly determined 
can probably be decided only by a visit to his station, Glen 
Onoko, Pa. No specimens bearing this name were seen in the 
Wolle herbarium. 
DRAPARNALDIA RAVENELII Wolle, F. W. Alg. 110. ۸ 95. 
1887. DeToni, Syll. Ale 1: 193. 1889. 
Batrachospermum vagum Ravenelii Wolle, Bull. Torrey Club, 
O: 29. 1882. 
This species seems to possess strongly marked characters in 
the large diameter (150-170) of the filaments and the crowded 
sessile fascicles of branchlets. We have found no report to show 
that it has been collected since the type specimens were obtained 
by H. W. Ravenel in South Carolina. It is strange, but rather in 
keeping with Mr. Wolle’s methods, that in describing this species 
as Draparnaldia, no reference was made to the earlier disposition 
of it as Batrachospermum.
