described to be, an ai'boresccnt Fern, and that it has been confounded with that 

 species. There are a very few black spinescent tubercles on the glossy stramineous 

 upper extremity of the stipes, as if the lower ])ortion might like that be much 

 aculeated. In the general form of the pinujc it certainly very much resembles 

 our Pt. Kunzeana, but these are of a much more pellucid and somewhat succu- 

 lent character, of a pale green colour, as if grown under the shade of trees : yet 

 I cannot agree with the excellent Agardh in its being " distinctissima species." 

 The venation, which he dwells upon, does not appear to me to differ in any 

 essential respect from that of its allies. 



112. Pt. (Litobrochia) microdictt/on, Fee; "fronds pin- 

 nato-pinnatifid, racliis subtrigonous channelled on the supe- 

 rior side, pinnfe pinnatifid acuminate shortly petiolate alter- 

 nate, segments lanceolate falcate slightly dilated at the base 

 obtuse crenated spreading at the sinus, basal areole narrow 

 the rest of the areoles minute, sporothecia thick not extend- 

 ing to the margin, indusium very narrow spurious receptacu- 

 liform the margin thick and black, sporangia elliptical, annu- 

 lus 18-20-articulated, spores trigonous blackish, sporangiastra 

 intestiniform." — Litobrochia microdictyon, Fee, Gen. Fil. p. 

 138. 



Ilab. Philippine Islands, Cuming. — A tall Fern, ovoid in circumscription ; 

 stipes reddish. — This is placed next to Litobrochia setifera by M. Fee ; of its exact 

 affinities I am ignorant, as I am also of the following species of M. Fee. 



113. Pt. (Litobrochia) Borbonica, Fee; " fronds pinnato- 

 pinnatifid, stipes yellowish, above broadly canaliculate, pinuce 

 pinnatifid sessile terminal ones wider on long pedicels acumi- 

 nated serrated at the apex, segments deeply divided lanceo- 

 late rather obtuse crenulate at the apex, sinus narrow, nervils 

 slender not reaching the margin thickened at their apices, 

 areoles of the pinnae arcuate extended [extensis) those of the 

 segments subhexagonoid, rhizome creeping an inch long fibril- 

 lose, sporothecia short, indusia broad membranaceous, recep- 

 tacle none, sporangia elliptical large, annulus 18-20-articu- 

 lated {articulis discretis spissis) intensely red, spores large 

 trigonous opaque, sporangiastra none." — Litobrochia Bor- 

 bonica, Fee, Gen. Fil. p. 136. 



Ilab. Bourbon, Fee. — " Filix insignis, siccitate flavidula, nervillis tenuibus 

 rufescentibus, delicatula, translucida, glaberrima, segmentis eleganter crenulatis." 



114. Pt. (Litobrochia) Montbrisonis, Fee; "fronds very 

 ample, pinnules ovato-lanceolate sessile, segments lanceolate 

 obtuse entire sinuated unequal slightly curved {curvulis) 

 glabrous and pellucid, stipes and mesoneure reddish, sporo- 

 thecia not extending to the margin {murginem non att'inr/en- 

 iibus), indusium broad, receptacle none, sporangia elliptico-
