We know nothing of this plant, which is said closely to resemble Crowania attenuata, Can it be a Crouania, 
and not a Dasya? Perhaps Crowania insignis, Harv. ?

ramis erecto-patentibus, primariis longissime virgatis, secundariis tertiariisgue minoribus, omnibus distiche 
ciliatis, ciliis filiformi-subulatis distantibus alternis vel secundis, seepe uno latere pectinatis, ceramidiis infra 
apices ramulorum in rachide sessilibus lateralibus ovatis, ore laterali.—Harv. Alg. Austr. Exsic. n. 248. 
Haz. Georgetown, very rare, Rev. I. Fereday. 
Distri. Found at Western Port, Victoria, W. H. H. 
Frond 2 feet long or more, very soft and flaccid, twice as thick as hog's-bristle, excessively branched in an 
alternate manner, the main branches long and virgate, the rest successively shorter. All parts are more or less 
flexuous, or gracefully bending. The cilia are longer, more filiform, more distant, and less regularly placed than in 
D. elegans, and in the lesser division a cilium is frequently lengthened to twice or thrice the ordinary length, and 
then pectinated on its inner face. The whole plant has more the aspect of a Hypnea than of a Delisea, but the 
fructification is exactly that of D. elegans.
