sim in dentes latos diminutis; costa simplici siibs(|Uaniuli)sa, 

 inc(»ns|)icua; soro ad apiceiii ])innao solitario. 



Mindanao Isl., Mt. Apo, 1600 m. s. ni. on the mossy 

 trunks of trees (Copeland no. 1013). 



This var. is more slender and the pinnae are decidedly 

 finer and closer together than in the type. A pinna is very 

 rarely found bearing two sori, l)iit the var. and the type 

 (/>. contlgua) seem to maintain their distinctness when growing 

 in the forest side by side. 



2. Diivallia (Prosaptia) cxaltata Copeland n. sj). ]\hizoniate brevi, 



ascendente, paleis brunneis, linearibus, 6 mm longis dense 

 vestito; frondibus confertissimis, pendentibus, deorsuni atte- 

 nuatis, sessilibus, majoribus 500 x9 mm, j)arte tertia inferiore 

 sterili, vix ad rhachin pinnatifidis; rhachi 0,8 mm lata, viridi, 

 squamulis parvis, parcis, plerumque distantibus vestita; seg- 

 raentis inaequilateraliter triangularibus, ooriaceis, obtusis, planis, 

 glabris, infra punctulatis; venis invisibilibus; soris ad apices 

 segmentorum solitariis. 



]\Iindanao Isl., Mt. Apo, 1800 m. s. m., on the mossy 

 trunks of trees, in a moist forest (Copeland no. 1006). 



Young fronds are remarkably similar to Foliipodiuin cu- 

 cullatum, whicii often grows in the same clusters, with the 

 fronds mixed. The nearest relative is doubtless D. Freikrici et 

 Pauli Christ of the same formation on the mountains of 

 Celebes, a much smaller fern, with rhachis beset with broad, 

 appressed scales. 



3. Davallia Wairiicriana Co])eland n. sp. Rhizomate late scandente, 



valido, paleis brunneis, lanceolatis, acuminatis, ad|)ressis dense

 ginem rarius attingentibus. 



Mindanao Isl., Prov. Davao, Todaya, 1100 m. s.m., nn 

 high trees in the forest (Copeland no. 1300). 



This fern is nearest D. L(>hbi(nia ^looro, (it Hdiiioo. i)ur 

 is not at all deltoid, and the sori are usually dcej)er than wide.
