POLYPODIUM, § RUPOI-YPODIUM. 223 



large pinnrc (sometimes more than ^ an inch long), and the contraction where they 

 join on to the rachis, so that the point of attachment is comparatively small ; 

 and the margin is by no means decurrent ; yet the pinnae are in no way petiolate. 

 It is allied, however, to some forms of P. cuUratuni. 



133. P. (Eupolypodium) venulosum, Bl. ; caudex short ob- 

 lique or suljrepcnt ferrugineo-squamose stipites approximate 

 somewhat tufted 1-3 inches long and as well as tlie purplish- 

 black rachis and costa patently villose with long purplish hairs, 

 fronds a span to li foot long 1-1 ^ inch broad firm-membra- 

 naceous (young undeveloped ones clothed with dense pur- 

 plish deciduous hairs) elongato-lanceolate acuminate much 

 attenuated below (by the gradual dwarfing of the pinnaj) 

 pinnate, pinnse numerous approximate from a rather broad 

 base linear-oblong entire obtuse, costule slender flexuose and 

 as well as the rather distant obliquely erect simple veins very 

 conspicuous, sori oval sunk in an oval cavity with a distinct 

 raised margin in two rows parallel with the costa occupying 

 the whole space between the costa and the margin. — Bl. Fil.

Hab. Java, Blume, Thos. Lobb, Zollinger. — "Well distinguished by its pinnated 

 and not pinnatifid frond, and very patenti-villous stipites, from P. obliqualum, 

 Bl. ; and by the submembranaceous fronds and conspicuous venation from P. Ce- 

 lebicum. In this, and all the Cri/plosonis-group, probably, the receptacles of 

 the sori, in age, fall away and leave oval apertures in the segments.

 both extremities white-pulverulent subfarinose on both sides 

 pinnate below, the rest deeply almost to the rachis pinnatifid, 

 pinnae approximate subhorizontally patent 1-H inch long 

 nearly j of an inch Ijroad linear-oblong obtuse subexcised at 

 the base below but a little decurrent auricled at the truncated 

 base above, subsinuated otherwise entire, veins once forked 

 clavate at the apex, upper branch soriferous, sori subrotund 

 rather large golden-yellow forming a series halfway between 

 the costa and the margin. — Hook. Ic. Plant, t. 947 {or Cent,

Hab. Rare ; trunk of an old tree on the eastern descent of the Cordillera of 

 Quito, where the forests commence, Jameson. — A very remarkable species.
