Ferns. ^^^ 



hint of a disposition to become larger or less amorphous in 

 the considerable amount of fertile material collected by 

 Mr. Elmer speaks for its specific distinctness. It suggests 

 P. nummularium in its shape and size, but even Avhen the 

 veins are free their mode of branching marks it unmistakably 

 as a Phymatodes. 

 Polypodium (Phymatodes) validum Copeland n. sp. Rhizomate 

 brevi, crasso, paleis ovatis, adpressis, fuscis, obtusis, cordatis 

 vel peltatis vestito; frondibus caespitosis, fere sessilibus, in- 

 tegris, carnoso-coriaceis, fragilibus, lanceolatis, subacutis, de- 

 orsuni in stipitem alatum attenuatis; venis lateralibus primariis 

 fere ad marginem manifestis, itemfjue venulis majoribus, ar- 

 cuatis, costae parallelis; areolis primariis ca. 7- seriatis, venulas 

 liberas utrinque includentibus, divisis; soris copiosis irregula- 

 riter dispersis. 



Mindanao Isl , Prov. Davao, Sibulan River, on the stones 

 of river banks, 500 m. s. m. (Copeland no. 973). 



Large fronds are 7 dm long and more than 1dm wide; 

 about 1/3 of the length is usually the winged stipe. The Ba- 

 gobo name is "Z^orawe", applied to all ferns of similar shape 

 and texture, terrestrial and epiphytic. The nearest species to 

 this is probably P. piinctatiim L., which jis smaller, thinner and 

 linear, and usually epiphytic. Broad ferns from Prov. Bataan, 

 somewhat intermediate, are doubtfully referred to P. pimdatim. 

 . Polypodium (SelUg-uea) Elmeri Copeland n. sp. Rhizomate 

 repente, valido, 5mm crasso; paleis 6mm longis, ovatis, acu- 

 minatis, marginibus scariosis, basibus peltatis nigro-maculatis; 

 stipitibus validis, glabris, fuscis vel ati'escentibus, frondis ste- 

 rilis 3 — 6 cm alto, fertilis 15 — 20 cm alto; fronde sterili ovato- 

 triangulari, ca. 10 cm alta, 6-8 cm lata, obtusa, Integra vel 

 subsinuata, ad basin truncata, glabra, rigidissime coriacea; venis 

 parallelis conspicuis, marginem attingentibus , venulis occultis; 

 fronde fertili 10 cm alta, 4 cm lata, acuta, subintegra, deorsum 

 cuneata, coriacea; soris continuis, costam marginemque attin- 

 gentibus , angustis. 



Luzon Isl., Prov. Benguet, Mt. Sancto Tomas, epiphyte 

 on pine trees (Elmer no. 6547). 



This species is nearer P. vulcaiiimm Bl. than it is to 

 P. caudiforme Bl., agreeing with the former in the dimorphous,
