DESCRIPTIONS OF THE SPECIES 
227 
Another specimen (named C. hirta , var. parviloba , smaller 
specimen only), which I cannot distinguish from this, has alter- 
nate pinnae one inch apart, one inch long, quarter inch broad, 
and with six to nine pairs of linear-lobed pinnules, half line 
or less broad, one to two lines long, all coated underneath 
with rusty scales and tomentum. 
C. hirta , var. cornuta of the Herb. Gub., which seems to 
be Pappe and Rawson’s C. cornuta Kze, must also be referred 
here, though approaching more nearly the ordinary compact 
form of C. hirta , to which this species as a whole stands in 
much the same relation as does C. parviloba ; only that this 
is densely tomentose below. Baker includes C. cornuta Kze 
in Pellaea involuta Bkr, except Ecklon’s plant described by 
Mettenius ( Cheil ., No. 33), the identity of which he doubts. 
Pappe and Rawson’s description would not exclude the 
present species, but Kunze remarks : “ Species not to be 
compared with any, unless with the small contracted form 
of Pellaea hastata , but the rigidity of the fronds, sub-linear 
form, and spreading sori, easily distinguish it.” 
This refers rather to C. involuta , and I have therefore 
taken Baker’s name for the present species. Baker describes 
the frond as four to six inches long, quarter to one-third of 
an inch broad with stipe three to four inches long, and omits 
mention of the tomentum, but, as shown above, more speci- 
mens are yet required to show the limits of the species. 
Christensen maintains C. cornuta Kze, C. depauperata Bkr 
and Pellaea involuta. I think C. cornuta might be dropped.

Crown procumbent, with abundant rusty brown lanceolate 
scales. Frond three-pinnatifid, lanceolate, six to eighteen 
inches long, one to four inches broad, on a dark brown stipe 
three to six inches long, more or less scaly at the base, and 
like the rachis and veins, thickly set with soft spreading, 
jointed, glandular white hairs, which in old fronds become 
rusty. Pinnae opposite below, alternate above, plain (i.e. not
