A species closely related to D. straminea Labill., but strongly pilose, larger, 
quadripinnatifid, the pinnae and pinnules l)roader and more stronjrly serrate, 
broadly deltoid, the pinnules of the third order broader tlu- lobes shorter and 
broader. Resembling the South American D. coniifolia S\v. 
MARATTIA Smith. 
All the riiilippine forms of this genus that 1 have examined liave been identified 
after the classification in the monograph of neVncse and TTarfing, in whicli work 
the diagnoses are by no means comparative and in >vhich the difTerenees between 
related species are not noted. The number of species is so large and their 
characters so xmiform that the distinctive characters of each species should have 
been emphasized. At any rate the group merits more attention than 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 
difTerenees between young and adult fronds are very great, and the latter, even 
the fertile ones, frequently present characters that are ordinarily found only 
r 
in young fronds. Tn diagnoses the adult parts only have been considered. 
I have been able to elucidate here, with a fair degree of certainty, the 
following forms: 
96. Marattia sambucina Blume. Enum. (1828) 256; DeVriese et Harting 
Slonog. 6. 
Toxtura firiniter chartacca, rhachi laevissinia flava, pinnulis sessilibus 
basi acute cuneatis, acutis, adultis 7.5 raro 11 cm. loiigis, 1 ad 1.4 cm. 
latis, margiiie omnino dentatis, dciitibiis obliquis raro patentibus, synangiis 
1.5 mm. a margine rcmotis 1.5 mm. longis non contigiiis late ovatis, 
6 ad S-loculatis. Colore pallide viridi.

r 
[Loher) January, 1893: Province of X'nion, Castilla [Loher) March, 1906. 
This is the most widely distributed form, identical with specimens from Java 
1^. Radhorski and from Celebes leg. Sarasin. It is the form previously con- 
sidered by me as M. fraxinea.^ 
97. Marattia silvatica Blume Enum. (1828) 256 ;_ DeVriese et Harting Monog.

Firmitcr cbartacea, rliacbi laevissima flava, piiinulis petiolulatis, basi 
acute cuneatis acutis, adultis. 9 cm. longis 13 mm, latis, margine omnino 
dentatis, dcntibus brevibus patentibus, synangiis fere marginalibus, fere 
contiguis, 2 mm. ct ultra longis, oblongis, 12 ad 15-locularibus. Colore
