204 CHAETOPHORACEAE 
Draparnaldia uniformis Ag. Flora, 10: 635. 1827 ; Icon. Alg. 
Eur, M. 37. 1835; (7?) 
Bright green, somewhat creeping at the base, branches numer- 
ous, branchlets rather remote, alternate or opposite, erect or some- 
what divergent, attenuated upward to an acute apex ; cells 7.5— 
12 in diameter, 1-2 times as long, in the branchlets 3-5 times as 
long. 
In warm springs and hot water waste from mills, etc. 
Wolle's figure seems so well in accord with the species, that 
there is no good reason for question in regard to it. Draparnaldia 
uniformis has usually been considered a variety 0۶ 1 
tenue, but both in respect of general character and habitat, it 
appears to be more closely allied to this species.

tapering somewhat, obtuse or short-pointed ; cells 6-8 مر‎ in diame- 
ter, and 1-2 times as long.

tember, 1897 (De Alton Saunders). 
The figures given by Wolle and Saunders are sufficiently like 
those of Dillwyn and Cooke, so that the identification of their 
plants can hardly be questioned. At the same time, it appears 
very probable that this species is only a young state of some 
other. The specimen from South Dakota particularly has this 
appearance and the lack of strongly marked characters in the diag- 
nosis points to the same conclusion.
