 Dryopteris achiatn (Bl.) v. A. v. R., Ml. Pangeranggo, agrees with 

 Blumes original description, but not with that of v. A. v. R.; D. 

 sarawokensis (Baker) Copel.; Tectaria gigantea (Bl.) Copel.; Athyrmni 

 peter&e)in (Kze) Copel. comb. nov. {Asplenhim petersenii Kze), near 

 A. japoniciim (Thunb.) Copel.; A. pulcherriniiiui nov. spec., PI. III, 

 Mt. Pangeranggo, the v^xy uniform dissection of the ample frond 

 gives this fern a strikingly attractive appearance; A. subscabnim 

 nov. spec, PI. IV, Poentjak Pass, Megamendoeng Mountains, a 

 species of uncertain position, it seems most likely to be a relative 

 of Diplasiitm aspenim Bl.; A. pariens Copel., M t. Salak, this is 

 very possibh^ identical with A. ForhesH (Baker) Copel. {Asplenmm 

 Forbesii Baker); A. siibserratum (Bl.) Milde; Pieris vemilosa BL, the 

 most remarkable Charakters of this species are given; Polypodium 

 javanicmn Copel. nov. sp., near Tjibodas, a relative oi P. khasyamim 

 Baker, P. barathrophylhim Baker and P. negrosense Copel., but 

 easily distinguished from all by the close, usually imbricate segments.

Copeland, E. B., On PhvUitis in Malaya and the supposed 

 genera Diplom and Tviphlebia. (Philipp. Journ. Sc. C Botany. 

 VIII. p. 147—153. PI. 5 7. 1913.) 



The genus Diplora {D. integrifolia from the Soloman-Islands) 

 is invalid, because founded on a misconception of the structure. 

 The actual structure is that of Phyllitis. This could be proved by a 

 comparison of fragments of the type with other specimens, which 

 had been named Phyllitis manibare (Bailey). 



The genus Triphlebia is invalid , because founded on inconstant 

 „characters" and again in part on illusory ones. 



Phyllitis, including the above, has only three well-defined 

 species in ihe Malay-Polynesian region: 



P. schisocarpa (Copel.) v. A. v R. 



P. longifolia (Presl) O. Ktze, with which Scolopendrium pinnatum 

 must be united. Presl's name is the older one and therefore has 

 the priority. 



P. durvillei (Bory) O. Ktze. With this species must be united : 

 Diplora integrifolia Baker, Asplenimn Linsa Cesati, Triphlebia 

 dimorphophylla Baker, Scolopendrium Mambare Bailey, Phyllitis 

 intermedia v. A. v. R., the New Guinea ferns called Scolopendrium 

 longifolium Presl, and probably Asplenium scolopendropsis F. Mueller. 

 All are more or less perfect specimens, more or less adult in 

 characters — the more juvenile being more likely to reveal di or 

 polymorphism — grown under conditions more or less favorable 

 to iuxuriant Vegetation. 



The second supposed species of Diplora, D. Cadieri Christ, was 

 promptly declared by its author to be nothing more than a form 

 of Stenochlaena. 



The most primitive species of Phyllitis is P. Durvillei. It in 

 turn is descended from Asplenium, from A. epiphyticum or some 

 similar form. 



Aspleinuni epiphyticum is an extant fern which very nearly 

 represents stages in the ancestr}'- of the genus Phyllitis, the genus 

 Stenochlae}ia, and the Nidus group in Asplenium.
