 free veinlets ; sori scattered, very copious. P. irregulare, Presl. Hk. Sp. 5.

Hab. Malay Peninsula and Isles. P. petropkyum, Blume, is said to differ by its longer 

 ultimate lobes and copious free veinlets.

 towards the base ; fr. 2-3 ft. 1., 1 ft. or more br. ; pinnae distant, 7-8 in. 1., 

 1^-2 in. br., the apex acuminate, the edge slightly repand, the base narrowed, 

 the lower ones stalked ; texture herbaceous ; both sides naked ; no distinct main 

 veins ; areolce rather large, without free veinlets ; sori small, scattered irre- 

 gularly. Hk. Sp. 5. p. 92. 



Hab. Sierra de Crystal and Old Calabar, West Tropical Africa, Mann. 



90. P. (Dicty.) draconopterum, Hk. ; rhizome woody, the scales lanceolate, 

 dull-brown ; st. 2-3 ft. 1., firm, erect, scaly below ; fr. 3-4 ft. 1., 2 ft. or more br., 

 with a large oblong-acuminate terminal lobe, and several lateral ones on each 

 side, which do not reach down to the rachis, the lowest sometimes \\ ft. 1., 4 in. 

 br., and forked ; texture papyraceous ; both sides naked ; main veins distinct to 

 the edge, connected by distinct transverse veinlets with copious areolse with free 

 veinlets between ; sori minute, copious, scattered, often confluent. Hk. Sp. 5.

Hab. New Granada to Ecuador. 



*** Eremobryoid series. Stems articulated at the point of junction with the 

 rhizome, and sori generally, but not always, terminal on the veins. Polypodium.

fr. 1 in. 1., 1-1| lin. br., blunt, nan-owed gradually downwards, the edge entire ; 

 texture subcoriaceous ; both sides rather densely clothed with long soft hairs ; 

 veins simple ; sori few, round. Hk. Sp. 4. p. 172. 2nd Cent. t. 10. 



Hab. E. Peru, Spmce, 4746.

 narrowed very gradually below, the point bluntish, the edge entire or slightly 

 undulated ; texture coriaceous ; both sides when young rather thickly clothed 

 with long soft hairs ; veins immersed, forked ; sori roundish, in two rows, 

 ultimately confluent. Hk. Sp. 4. p. 167. 



Hab. Neilgherries and Ceylon. Probably this is the Javan P. pilosiusculum, Hk. 

 (Grammitis, Blume) ; and Q. adspersa, Blume, which we have not seen, is apparently very 

 near it. 



93. P. Hookeri, Brack. ; st. tufted, 1 in. or less 1., clothed with soft spreading 

 hairs ; fr. 3-5 in. 1., -f in. br., the point acute or bluntish, the edge entire, the 

 lower part narrowed gradually ; texture subcoriaceous ; both sides thinly clothed 

 with soft hairs ; veins simple or forked ; sori round, in long rows close to the 

 midrib. Hk. Sp. 4. p. 171. P. setigerum, Hk. fy Arn. (non Blume}. 



Hab. Sandwich Isles, Fiji, Queensland, Philippines. The Bourbon P. Beaumontii,
