DESCRIPTIONS OF THE SPECIES 
7 1 
long, one inch broad, on a wiry stipe one inch long or less ; 
very irregular as to cutting, but generally flabellate or sub- 
pinnate in general outline ; cut throughout into simple or 
forked linear pinnules, a half to one inch long, one line broad, 
and with one central vein in each; the main rachis when 
present winged like the other segments. Margin slightly 
toothed, with a hair point on each tooth. Involucre terminal 
on the upper pinnules, and quite sunk into the lamina, with 
short round spreading lobes. 
This species is a native of the Mascarene and Polynesian 
islands, and is given in Synopsis Filicum as a Cape plant on 
Dr Brown’s authority; but it has not been found by any 
collector since, and no Cape specimen exists in the Colonial 
Herbaria, nor is it in Kew Herbarium from the Cape, and 
Christensen excludes it. 
Can it have originated from small barren plants of Hyme - 
nophyllnm Marlothii Brause ? 
My description and figure are from Samoan specimens 
kindly forwarded to me from Kew.

Rhizomes long, slender, and coated with short black shag. 
Fronds sessile or almost so, glaucous green, membranaceous, 
very irregular in outline, sometimes linear-oblong and sinuate, 
more frequently obovate from a cuneate base, deeply pinna- 
tifid into rounded, irregular pinnules, more or less wavy at the 
margin, and with frequent blunt lobes or teeth, crowned by 
two or more sessile hairs arranged stellate fashion. Fronds 
a half to one and a half inches long, a quarter to three-quarter 
inch broad, and bearing the sori terminal on the veins in the 
upper part. Involucre quite exserted, tubular from a con- 
tracted base, and having two large semi-circular lobes at the 
mouth. Receptacle twice as long as the tube, but bearing 
capsules only on its lower half. The veins are pinnately 
arranged, but numerous ; spurious venules exist, generally 
leading up to the tufts of hairs.
