2. Gleichenia vulcanica HI. 



Like the preceding, but more alpine in habit, more densely pubescent, 



the larger scales 1..") to 2 mm long, ciliate rather than deeply lacerate. 

 and usually reddish- or greyish-brown. Stunted specimens are not at 

 ;dl forked, bearing the "pinnules" directly <>n the unbranched main axis 

 of the frond. 



•Java. Celebes, Philippines. 



3. Gleichenia amboinensis v.A.v.H. Hull. Dep, Agr. End. Neerl. 18 (1908) 3. 



Fronds 50 to 100 cm high, dichotomous ;it the apex, otherwise pinnate; 

 rachis clothed with deciduous, tomentose or furfuraceous pubescence; 

 pinnae 2 or 3 pairs, erecto-patent, the upper ones dichotomous, the lowest 

 pinnate, dichotomous at the apex : pinnules dichotomous, all their branches 

 foliaceous, deeply pinnatifid; segments linear-oblong, obtuse, crenate, 

 Mibcoriacous, usually glacous beneath. 1 to 2 cm long, about 2 mm wide, 

 the lowest ones usually reduced and suborbicular ; the ultimate branches 

 acuminate, with coarsely toothed apex ; eosta> with a deciduous pubescence. 



Ambovna. Buru. 



4. Gleichenia hirta Bl. {(I. dolosa C'opel.) 



Frond, including stipe, often 1.5 m or more high; stipe very stout. 

 brown-scaly at the base, younger axes bearing a pale scurf and ciliate, 

 lanceolate, brownish scales 1.5 mm long: rachis forked at the top but 

 with a terminal bud of apparently indeterminate growth, and below this 

 usually 2 to -4 pairs of pinna 1 , which are 3 or 4 times forked and foliaceous 

 above the second fork from the bottom; ultimate branches up to 25 cm 

 long; segments up to 13 mm long and 2.5 wide, not quite horizontal, 

 just in contact at the base, serrulate at the apex and rather obtuse, 

 herbaceous, glabrous above but not beneath, usually very glaucous beneath ; 

 sori of 3 or t sporangia. A beautiful plant. 



Philippines, Moluccas: Java? 



5. Gleichenia hispida Mett. 



Fronds 50 to 100 cm high, stipe very stout and brittle, younger axes 

 densely i'erruginous-t'elty, and the growing tips buried in felt, the paless 

 sparsely long-ciliate; rachis forked at apex, and below this bearing 1 to 

 3 pairs of pinna 1 which are usually 3 times forked and foliaceous through- 

 out ; segments not quite horizontal, mostly straight, up to 22 mm long, 

 about 1.5 mm wide, acute, moderately revolute, distinct and separated by 

 their own width, coriaceous, glabrous above; sori mostly of 4 sporangia. 

 G. koordersi Christ seems to be a rather depauperate form of this species. 



Java, Celebes. Termite and Luzon, on mountain tops. 



It. Gleichenia vestita HI. 



Fronds 50 to 100 cm high, the axes clothed with brown scales 3 to 5 

 mm long, 1 mm wide; rachis light brown, forked at the apex, and below 

 this bearing one or more pairs of pinnae which are 1 to 3 times forked
