species is variable, like all Hawaiian ferns. Its only constant character consists 
= the straight and dark hair which rises from sharp tubercles often in the entire length of 
er ay , barely the tubercles, not the hair, extending to the lower portion of the main 
ed chis of the lower surface (C. pruinatum) is often very conspicuous, 
t some n a - it wo seem 
ore: 
to fade away in “herbariam specimens. As a rule the lower surface is quite glabrous, 
ovate or deltoid on a long stipes, simply pinnate mly 3 : 4 pairs of free pinnae, 
which are cut to the middle into broad and sorta gion pital lobes. 
.C. Chamissoi, Kaulf. Enum. Fil. p. 230, tab. 1, fig. 14. — Trunk less high 
than in the preceding species. Stipes 4—8 ft. long, brownish, smooth, 
clothed at the base with a pale fawn-colored lustreless matted or cobwebby 
pulu, furfuraceous or naked above. Frond 4—8 ft. long, chartaceous, the 
under face green or dull glaucous and generally covered with a pale cob- 
webby pubescence. Lowest pinnae 11/2—2'/2 ft. long, with 24—28 pairs of 
pinnules; these shortly pian a linear-lanceolate, 5—6‘ X 8—10", acute, 
the lower ones cut to n the rhachis into oblong, straightish, rather 
obtuse segments with narrow sinuses, the basal segments entire and not 
deflected, boon little prominent. Sori 8—14 to a segment, the involucre 
small, about 12“ wide, chartaceous. — Hook. Sp. Fil. I, 83. — Synops.

All islands! In Hawaii trunks hay n seen of 16 or more feet in height. The 
young stems of this, and probably also of the other Fegan: are farinaceous and used to 
be eaten by the natives in times of scarcity. Baked in ashes they are by no means un- 
palatable. Nat. name of nos. 2 and 3: «Hapu» 
The uubescence of the frond is cadninmate saat 2 in the upper Pose pice and pinnul 
to be glabrous. His figure otherwise agrees well with our specimens. A y yeni plant, 
about 1 ft. high, is bipinnate, with the pinnotes — serrate. One of my young plants 
has quite pale flaxen hair, not as curly as 
— var. — Pulu as me «. Frond smaller, thin chartaceous, dull glaucous 
underneath, the primary and secondary rhachides covered with short 
kes of ‘rook seaheg — 15‘ long; the pinnules 3—5‘ K 5—8”, sessile, 
the lowest segments free, entire, that of the under half overlapping the 
rhachis, as in C. glaucum. Veinlets mostly simple. Invol. very small 
and thin. 
On high lands of Kauai! (Kn.) and doubtfully also of Hawaii! (Lydg.). 
3. C. glaucum, Hook. ¢& Arn. in Bot. Beech. p. 108. — Sp. Fil. I, 82, 
tab. 29, A. — Trunk and stipites as in no. 2, but the pulu at the baie 
of the latter’ glossy, sige yellow, moderately curled, the upper portion 
of the stipes naked or slightly furfuraceous. Frond 6—8 ft. long, sub- 
coriaceous to Saciasioa bright-glaucous underneath and naked, as are
