STENOSEMIA Presl. 



Stenosemia pinnata Copeland n. sp. 



Caudice erecta, valida; atipitibua caespitosis, atro-fiiscia vel uursum 

 llavescentibus, paleas paucaa distantes deciduas I'ereutibus, I'mndium 

 sterilium 25 cm. fertilium 40 cm. altis; fronde sterile deltoideo-ovata, 

 30 cm. alta, 20 cm. lata, pinnata; pinnis infimis atipitatis, subfalcatis, 



acuminatis, ovatis, 8/3 ad costam pinnatifidis, segmentis basiscopieis 

 majoribus serratis, stipitem versos diminutis, sinubus setis miimtis ob- 

 structs; pinnis sequentibus aessiiibus, dein adnatis, decurrentibus, demum 

 in apicem compositam coadunatis, membranaceis, fere glabris; rhachi 

 dense brcvi-pubcscentc ; fronde fertile forma eadem, 10 cm. alta, bipin- 

 nata. 



Mindanao, Zamboanga, San Ramon, Copcland 1601. Ad terrain in silvis, 

 alt. 100 m. 



This species grows associated with 8. aurita Fresl. Tlie basal pinnae are but 

 little larger than the succeeding and the longest basiscopic lobes are one-third of 

 the way to the tip. Three or four pairs of pinnae are free. 8. aunt a in this 

 locality has its upper surface sparsely but uniformly hirsute. 



LEPTOCHILUS Kaulf. 



Leptochilus hydrophyllus Copeland n. sp. 



TJbizomate brcvi-rcpente, 1-1.5 mm. crasso, apicem versus paleis fuscis, 

 angustis, 1 mm. longis vestito ; .stipite frondis sterilis circa 1 cm. alto, 

 subsquamoso, frondis fertilis 4-7 cm. alto; fronde sterile plcrumque 

 10 cm. alta, 10 mm. lata, intcgra, rarius 20 cm. alta et undulata, acuta, 

 basi subacnta, viva carnosula, sicca papyracea, glaberrima; Tenia immersis, 

 inconspicuis, marginem vix attingentibus, venulis more L. cuspidati anas- 

 tomosantibus, liberis inclusis pancis; fronde fertile lineare, ca. 7 cm. 

 lata, 3 mm. lata, obtusa, in stipitem sensim angustata. 



Mindanao, Zamboanga, San Ramon, Copcland 1665. Ad saxa huinida. 



Well distinguished by the combination of the venation of Heteroncuron (as L. 

 cuspidatus) and the narrow fertile frond of typical Leptochilus (as L. decurrens 

 Bl.) ; the texture and the rather abruptly contracted sterile fronds are also 

 peculiar. 



NEPHROLEPIS Schott. 



Nephrolepis glabra Copeland n. sp. 



Species Nepbrolepide cordifolia, qua stipite rbachique alata glabrius- 

 culis vel glabris, pinnis fertilibus crenato-serratis, venulis manifestis, 

 textura herbacea staturaque minore differt, segreganda. Fronde 7-15 

 cm. vel rarius ultra, alta, lanceolata, more Muscorum Hymenopbylla- 

 cearumque desiccante, pinnis vix deciduis. 



LUZON, Benguet, Baguio, Copeland 1810. Plerumque ad saxa, sub Pinis. 



Judged by the formation of tubers, and by the shape of the indusium and posi- 

 tion of the sorus, this would be N. cordifolia (L.) Presl, a species common 

 throughout the Philippines. In a genus of xerophytes, epiphytic or inhabiting 

 dry copses, this species is notable for its exposure to extremes of moisture.
