232 BOTAKY OF THE A'OYAGE OF H.M.S. HEUALD. 
This species is only known to mc in the present collectiou. It is allied to C. Phyllitidis and C. repens, 
and approaches to a slender species from Xcw Granada; but it differs from the whole of the genus in its 
venation being entirely immersed, not showing elevated lines as in the other species.

I agree with M. Puc in the propriety of separating this species from Pferopsis anfjustifoUa ; it differs 
both in habit and venation. In Pteropsis angustifolia the venation is uniform reticulated, forming trans- 
verse elongated areoles ; whereas in Dicranoglossum the veins are simple, or forked and free, or their apices 
transversely combined by a marginal vein, which in the fertile fronds becomes the sporaugiferous recep- 
tacle. Pee enumerates three species belonging to the genus, but they differ so little, that I am inclined to 
consider them as merely climatal modifications of one normal species ; in some of these species the sterile 
veins are free, while in others they are combined ; and in specimens from Quito, instead of the sorus being 
continuous, as characteristic of the genus, the sporangia are produced in definite ovate-oblong nearly con- 
fluent sori, a structure which may be viewed as the simple or normal state. The linear or continuous sorus 
generally seen in specimens from the "West Indies, is the consequence of an elongation and lineal conflu- 
ence of the sporaugiferous points, being analogous to what is observed in the allied genus Pleopeltis. 
Pee has characterized this genus imder tlie name of Cuspidaria, but that name has already been applied 
by De CandoUe to a genus of Bignoniacece, which, to prevent confusion, should certainly not be disturbed ; 
I have therefore, and in accordance with the law of priority, in the present case substituted my manuscript 
name of DieranogJossum.
