174 DAVALLIA. 



veins sunk obsolete (inconspicuous) generally forked, the 

 upper veinlet bearing the sorus, involucres small half-cup- 

 shapecl, stipes and subtrigonal rachis glossy. (Tab. LX. B.

Hah. Philippine Islands, (Crtm?w7/cs). Luzon, Cwwi)?^, n. 139. Pe- 

 nang, Wallich, Ladij Dalhousie. Java, Blume. — Evidently allied in habit 

 and fructification to the orinjinal Saccoloma, and Presl has done right in 

 placing it there, if that genus were worthy of being retained; it differs how- 

 ever from every known species of Davallla, except the following, with which 

 it came mixed in Cuming's plants from the Philippine Islands, and from 

 which it may not be specifically distinct. 



56. D. Liizojiica, Hook. ; caudex short entangled some- 

 what creeping paleaceo-crinite, fronds ovato-lanceolate pin- 

 nate, pinnae lanceolate deeply pinnatifid sessile subcoriaceous 

 lobate on the long narrow acumen, segments linear crenato- 

 serrate, veins pinnated obsolete, sori at the base or in the 

 axils of the teeth, involucres small half-cup-shaped, rachis 

 and stipes subtrigonal. (Tab. LX. B. f. 2, 3, 5). 



Hab. Luzon, Cuming, (with the preceding, 7i. 139). — Had I received 

 this separately from the preceding, I should have felt satisfied of its being 

 a distinct species : but coming in company with that, and finding it to 

 have the same harsh almost coriaceous texture, and other points in com- 

 mon with it, I was led, at first, to look upon it as a variety : still, having 

 no intermediate states, I think it safest to give it as distinct : and the 

 characters are very apparent on the slightest glance at the figures. 



57. D.serrata, Bl.; "frond pinnate glabrous, pinna? alter- 

 nate subsessile linear-lanceolate falcato-acuminate duplicato- 

 serrate cimeate at the base, sori submarginal, stipes glabrous 

 subtetraquetrous." Bl. En. Fil. Jav. p. 232. 



Hab. Mountains of Java, Blume. — Blume places this next to D. pin- 

 nata, and observes of it, " serraturis obtusis emarginato-bidentatis priori 

 diflFert." 



Subgen. VI. Odontoloma, J. Sm. Sori intra marginal, generally at 

 the base of a large tooth or lobule. Involucres small, membra- 

 naceous, fixed by their more or less broad base, the sides free, 

 often reniform, rarely a little confluent, 1. e. two from the api- 

 ces of the adjoining veins (ivhere they are always situated), 

 running into one : or in other ivords, the sorus, in such cases, 

 appears to originate from the apices of two veins. — Tropical 

 Ferns of the Old and the New World. Caudex, I believe, 

 creeping in all the species. Fronds small {rarely or never ex- 

 ceeding afoot in length), membranaceous. Pinnse or pinnules 

 more or less dimidiate : the loiver margin straight or incurved
