pyramidal, pinn£E sessile adnate oval-oblong lobato-piiinatifid 

 and subdeiitate, veins forked, sori oblong and forked. (Tab. 

 CCXC.) 



Hab. Peru, Mathews, n. 1814. — As I have already observed, this appears to 

 me very distinct from G. mohriaformis, of which my authentic specimens arc 

 very perfect. This is a mucli larger and sto\iter and truly bipinnate species, with 

 very distant primary pinna?, eacli one of which well represents an entire frond of 

 G. mohricpformis in size and form. Here the frond itself is attenuated from below 

 the middle. 



8. G. (Eugymnograinme)m?'c7'o/>//y//«, Hook.; caudicesvery 

 slender filiform sul)repent and intertwined so as to form a 

 collection of tufted wiry fibres, stipites copious slender fili- 

 form very fragile dark-purple ebeneous glossy 2-4 inches 

 long, fronds membranaceous subdiaphanous \\-2h inches 

 long glabrous triangulari-ovate 3-pinnate (or piimate and 2-3- 

 pinnatifid), lowest primary pinnee half-ovate the rest oblong, 

 ultimate pinnules (or segments) oval-lanceolate entire acute 

 decurrentupon the rachises which thus become winged, veins 

 dichotomous one in each pinnule or segment oblong not 

 forked, veinlets terminating below the apex. — Hook. Ic. PL 

 t. 1916 [or Cent, of Ferns, t. 16). 



Hab. On trees, Surureen and Sanahola, Khasya, Griffith. — A graceful little 

 Fern, of which the delicate wiry caudicesonly seem to be perennial, for they form 

 very dense tufts full of the bases of former years' stipites. In other respects 

 somewhat allied to G. leptophijlla. 



9. G. (Eugymnogramme)^e.r?^o.s«, Desv. ; caudex creeping 

 firmly rooting with coarse wiry fil)res, stipites a span to 1 h 

 foot long purplish-black glossy flexuose, fronds tirm-mem- 

 branaceous 3-4 feet long having all the rachises singularly 

 geniculato-flexuose or zigzag with a somewhat oblong but 

 not easily-defined outline 3-4-pinnate sparingly pilose, pri- 

 mary pinnse 4-5 inches long more or less refracted, pinnules 

 dichotomo-flabelliform, segments more or less elongated li- 

 near or oblong obtuse entire or forked or emarginate, their 

 base decurrent forming a wing to the ultimate rachises, veins 

 forked following the course of the divisions of the segments, 

 sori elongato-oblong often forked as the veins. — Desv. in 

 Journ. Linn. Soc. vi. j). 215. Grammitis flexuosa, H. B. K.

* It is remarkable that Desvaux and Humboldt and Kuntb refer to a descrip- 

 tion of this plant in the PI. Equinox, ii. p. 167. t. 158, where it is certain no 

 such thing is to be found.
