MARATTIA Sinitli. 



All the Pliilippine fornis of tliis genus tbat 1 bave examined liave been identified 

 after tlie classification in tlie nionograph of DeVricse and Hfirtinrf, in whicli work 

 the diagnoses are by no nieans comparative and in wliicli the differences between 

 related species are not noted. Tlie number of species is so large and tlieir 

 characters so uniform that tlie distinctive characters of each species should have 

 been emphasized. At any rate the group nierits more attention tlian the succes- 

 sors to the two Dutch botanists have given it, for certainly the forms are very 

 numerous and can not all be reduced to a single species. The morphological 

 diflTerences between young and adult fronds are very great, and the latter, even 

 the fertile ones, frequently present characters that are ordinarily found only 

 in young fronds. In diagnoses tlie adult parts only liave been considered. 



I have been able to elucidate here, witb a fair degree of certainty, the 

 following forms: 



90. Marattla sambucina Blume. Enum. (1828) 256; DeVriese et Harting 

 Monog. 6. 



Textura firmiter chartacea, rhaclii laevissima flava, pinuiilis sessilibus 

 basi acute cuneatis, acutis, adultis 7.5 raro 11 cm. longis, 1 ad 1.4 cm. 

 latis, margine omnino dentatis, dentibus obliquis raro patentibus, synangiis 

 1.5 mm. a margine remotis 1.5 mm. longis non contiguis late ovatis, 

 6 ad 8-loculatis. Colore pallide viridi.

 (Loher) January, 1893: Province of Union, Castilla (Loher) March, 1900. 



This is the most widely distributed form, identical with specimens from Java 

 leg. Raciborski and from Celebes leg. t^arasin. It is the form previously con- 

 sidered by me as M. fraxinea.'^ 



97. Marattia silvatica Blume Eniun. (1828) 256; DeVriese et Harting Monog. 

 0. III. 25. 



Firmiter chartacea, rhachi laevissima fiava, pinnulis petiolulatis, basi 

 acute cuneatis acutis, adultis 9 cm. longis 13 mm. latis, margine omnino 

 dentatis, dentibus brevibus patentibus, synangiis fere marginalibus, fere 

 contiguis, 2 mm. et ultra longis, oblongis, 13 ad 15-locularibus. Colore 

 pallido.
