Ferns. 187 



Blechnum L. 

 1. Bleclmum cgTCgium Cupelaiul n. sj). Stipitibus nidiformi-cou- 

 fertis, 10 — 20 cm altis, validis, hrimueis, pedibus nigris, paleis 

 atris 20 — 25 mm longis, 0,5 mm latis dense praecipue deorsum 

 vestitis; fronde ca. Im alta, 30 cm lata, pinnata, subbiforme, 

 glabra; pimiis acuminatis, serratis, sursum coiifliientibus, medio 

 I'hachi late aduatis sed vero distiuctis, deorsum ad auriculas 

 siibremotas sensim diminiitis, fertilibus coriaceis, 15 cm longis, 

 ad rachin 15 — 20 mm latis, linear! - vel caudiformi-contractis, 

 patentibus vel recurvatis, sterilibus tenuioribus, 15 mm latis; 

 venida unaquaqiie in denteni acutum percurrente ; soris con- 

 tinnis costalibus, apices angustatas pinnarum versus paginas 

 totas fere complentibus; indusiis coriaceis persistentibus.

 ground near brooks, 500 m s. m. (Copeland no. 1314). 



Sterile fronds of this elegant fern are common along 

 creeks near Todaya, but fruiting fronds were encountered 

 but once. It is quite intermediate between the old genera 

 Bleclimim and Lomaria [Stegam'a R. Br.), and amply sup- 

 ports DiELs' judgment in combining them. The young fronds 

 remain a long time red. 



Drymoglossum Presl. 



1. Dryinog-lossum confertiim Copeland n. sp. Rhizomate tenui, 

 repente, intricato, squamulis parvis, tenuissimis, brunneis, 

 lanceolatis, acuminatis vestito; frondibus brevi-stipitatis, con- 

 fertis; fronde sterili elliptica, crassa, glabra, Integra, cordata, 

 apice rotundata, venis anastomosantibus areolas parcas confi- 

 cientibus, venulis liberis inclusis nullis; fronde fertili lineari- 

 oblanceolata, in stipitem attenuata, apice rotundata, soris in 

 medio disco lateris inter costani et marginem, superficialibus, 

 sursum postremi^ totam paginam complentibus, paraphysibus 

 invisis. 



Mindanao Isl., Prov. Davao, Catalona, on the trunks of 

 trees, in moist forests (Copeland no. 942). 



Stipe 1 — 7 mm long; sterile fronds at most 18x13 mm, 

 fertile 25 x 3,5 mm. The dense layer of small leaves entirely 

 covers the trunk and the network of rhizomes. This seems 

 very distinct from any Drymoglossu?)i hitherto known.
