This species, which has all the appearances of a Lastrea, sometimes has the 
basal nerves joined. 
Endemic to the Philippines. 
43. Dryopteris stenobasis C. Chr. Ind. Fil. (1905) 294. Lastrea attenuate 
J. Sm. in Hook. Journ. Bot. 3 (1841) 412. 
Samar (327 Cuming). 
This species presents in the greatest degree the reduction of the lower pinnae, 
a character common to so many of the Philippine species. The position of the 
species, with its numerous nerves in the very narrow lobes, is uncertain and 
seems to approach Nephrodium. 
Endemic. 
44. Dryopteris orientalis (Gmel.) C. Chr. Ind. Fil. (1905) 281. Polypodium 
orientate Gmel. Syst. 2: 1312. 
Var. Webbiana (Hook.) Nephrodium Webbianum Hook. Sp. Fil. 4: 85. 
Differs from D. orientalis (Polypodium pectinatum Forsk. and Aspidium 
albopunctatum Bory) in lacking the calcareous coating on the upper surface 
and the lobes more horizontal and more angular, but it is not more than a 
variety of the African species. It is found also in Amboina and the Viti Islands, 
and appears- unexpectedly in the Philippines. The Island of Reunion is the 
intermediate place in its distribution. 
Mindanao, Province of Zamboanga, San Ramon (1712 Copeland) April, 1905, 
alt. 850 m. 
Eastern Malayan region, rare and widely distributed.
