UNDERW00D, L. M., A Summary of our Present Know- 

 ledge of the Ferns of the Philippines. (Bulletin of 

 the Torrey Botanical Club. Vol. XXX. 1903. p. 665—684.) 



A preliminary synoptic view of the genera of Pteridophyta known 

 to occur in the Philippine Islands, introduced by a brief historical 

 account of the more important collections, their disposition and syste- 

 matic treatment. The generic grouping adopted differs widely from that 

 of Hooker and Baker 's Synopsis Filicum and accords more 

 nearly with that of Die natürlichen Pflanzenfamilien; in the 

 Hymenophyllaceae, however, the treatment of Presl is followed. With 

 the exception of the Isoetales all the orders of Pteridophyta are repre- 

 sented in the Philipp in es flora ; and of the Filicales all the families 

 excepting the Matoniaceae. More than 600 species are known at present. 

 For the benefit of prospective field-workers directions are given for 

 the collection of adequate herbarium material and for recording neces- 

 sary data. 



The treatment is, briefly, as follows : 

 I. The order Ophioglossales comprises the Single family Ophio- 

 glo s sace ae containing the four genera Ophioderma, Ophio- 

 glossum, Botrychium and Helminthostachys. 

 II. The order Marattiales, comprising the single family Marattia- 

 ceae, is represented by three genera: Kciulfussia, Marattia and 

 Angiopteris. 

 III. The order Filicales is represented by the families Osmunda- 

 ce ae , Ceratopteridaceae, Schizaeaceae, Gleich enia- 

 ceae, Cyatheaceae, P oly p o d i a c e a e and Hymeno- 

 phyllaceae. 



1. Osmundaceae. A single species of Osmunda. 



2. Ceratopteridaceae. The cosmopolitan Ceratopteris. 



3. Schizaeaceae. Four genera are known: Lygodium, Lophi- 

 dium, Actinostachys and Schizaea. The last 3 have often been 

 united under the name Schizaea.
