Tjy its medial sori and more pubescent surfaces. It is smaller and often, 

 relatively broader than gracilis, of a duller colour, and with longer sori. 

 The margins are not, as a rule, reflexed, and the lowest pair of opposite 

 veins enter them above the sinus. 



5. G. diplazioides, Desv. — Rootstock erect, scaly ; s'ipites caespitose, 

 erect, 6-12 in. L, brown, dark-coloured at the base with a few 

 deciduous scales : fronds bipinnatifid, charcaceous, pellucid, nearly 

 glabrous, clear green, paler beneath, erect, lanceolate, 2-3 ft. 1. 6-9 in. 

 w. acuminate, reduced at the base ; rachis brown, channelled, puberulous 

 on the face ; pinnae spreading, distant or subdistant, 3-4^ in. 1. f in. w. 

 sessile and usually broadest at the base, the apex entire and more acute 

 than acuminate, cut down about f ths to the costae into flat broadish 

 blunt or rounded segments which are widest at the base, and 2 li. b., 

 the lowest pair usually enlarged , vein6 6-9 to a side, the lower ones 

 often forked, the opposite basal pair entering the sinus ; sori nearer the 

 the margin than midrib, linear on the lower veins and double when they 

 are forked. — Phegopteris Duchassagniana, Fee. Fil. Ant. t. 14 fig. 3. 



Frequent by the open way side ia the in the neighbourhood of 

 second-breakfast spring, near Mount Moses, St. Andrew at 2,000-3,000 

 ft. altitude. This differs from the other two species by its erect habit ; 

 longer stipites, few reduced pinnae at the base, which, too, are not so 

 small, clear coloured and nearly naked surfaces, less deeply pinnatifid 

 and acuminate pinnae, broader segments, the lowest pair usually enlarg- 

 ed, fewer and more open veins, the lowest pair of which meet at the 

 sinus and are often forked, with invariably longer sori than those above. 

 The sori show prominently on the clear pale under surface. 



6. G. cheer ophylla, Desv. — Rootstock short, fibrous, upright ; stipites 

 tufted, few or marry, erect, 4-6 in. 1., slender, the base chestnut-brown, 

 above thi* green, naked ; fronds subdeltoid, membrano-herbaceous, 

 naked, dark-green above, 3-4 in. each way, tri-quadri-pianate ; lowest 

 pair pinnae largest, and rather distant fro.n the next above, all, e recto- 

 spreading and freely petiolate ; pinnulae also stipitate ; tertiary seg- 

 ments flabellate-cuneate, li. b., once or twice cut to the base into 

 similar segments, the outer margin freely toothed ; rachis and costae flat 

 and margined, slender, green; veins dichotomously forked, flabellate, 

 terminating in the final teeth, which are a \ li. w.; sori copious, linear, 

 occupying all the veins their entire length, and confluent or nearly so 

 laterally, pale or brown coloured. PI. Fil. t. 50, C. Hooker and Grev.

Frequent at 4,000-5,000 ft. alt. on damp banks, rocks and waysides 

 and generally plentiful where found. This is a tender herbaceous plant, 

 of great fecundity, but short individual duration, and hence regarded as 

 an annual. It is most abundantly soriferous, the underside being covered 

 with the contiguous almost confluent lines of pale brown sporangia. 

 The lowest pair of pinnae are often so much larger and distant from the 

 others that the fronds in these instances appear trifoliate. 



7. G. schizophylla, Baker. — Rootstock fibrous, erect or oblique ; sti- 

 pites tufted, slender, erect, early farinose, dark chestnut -brown, polished, 

 1-3 in. 1 ; fronds membrano-herbaceous, naked, bright green, lanceolate 

 or oblong-lanceolate, \-\ or 1 \ ft. 1. 2-3 or 5 in. w. tri-quadri-pinnate ; 

 rachis slender, channelled, castaneous, polished, generally producing a 

 farinose but, and often forked near the apex ; pinnae numerous, conti-
