DESCRIPTIONS OF THE SPECIES

Sori not seen by us, but Col. Brause states that they are 
quite distinct from those of H. obtusum . Some of the Table 
Mountain specimens are four to six inches long (including 
stipe), two inches broad, and with lower pinnae two-pinnatifid, 
and as large as the whole frond usual size. A barren 
specimen from Knysna collected by Miss Rex, and marked 
in Herb. Gub.. H. lineare , is evidently this species, but is hairy 
on one side only, while the Table Mountain plant is hairy on 
both sides. A further specimen from Knysna (T. H. Rex, 
834, Sept. 1909) is hairy on both sides. 
The Table Mountain locality is mentioned in first edition 
of Syn. Fil. under the name of H. obtusum Hk. and Arn., 
but omitted in the second edition, where Sandwich Islands 
is the only locality given. It is also omitted by Kuhn, but 
he credits to the Cape the very closely allied H. aeruginosum 
Carm. 
Lady Barkly distributed many specimens from Table 
Mountain, and the exact localities in Skeleton Ravine and 
Disa Gorge are well known to several Cape Town botanists. 
Marloth also records it from Jonkershoek. 
In Mr Marquardt’s fern grotto, plants of this species 
originally from Table Mountain grew well. From Mrs Young 
I received a few fronds of this, mixed among H. tunbridgense, 
but without locality. Her specimens are mostly from Kaffraria 
and Natal. 
Christensen maintains H. obtusum from Hawaii and New 
Guinea, but includes the Cape plant in H. ciliatum Sw. 
H. Marlothii Brause, Fedde Repert. 11. 112 (1912).

Baker’s description in Syn . Fil. is: “Stem 1 — 2 in. long, 
ciliated and decurrently winged above ; frond oblong acu- 
minate, tripinnatifid, 2 — 6 in. long, 1 — 2 in. broad at the 
centre; main rachis broadly winged throughout and ciliated; 
lower pinnae oblong or rhomboidal, with a broad central un- 
divided portion, and numerous erecto-patent simple or forked
