POLYPODIUM, § EUPOLYPODIUM. 229 



mary segments patent 1 h-2 inches long more than \ of an 

 inch hroad lanceolate gradually but obtusely acuminated 

 deeply pinnatifid, the segments lanceolate acute erecto-pa- 

 tent entire or subpiunatitidly and acutely serrate, lowest su- 

 perior segment the largest and often again pinnatitid, costa 

 black, veins one to each segment very distinct reaching nearly 

 to the apex and bearing the sorusl)elovv the extremity (hence 

 a Fhecjopteris), sorus small in proportion to the breadth of 

 the segment. (Tau. CCLXXIX. A.) 



Ilah. Honolulu, Sandwich Islands, Dr. Hillehrand. — Extremely different from 

 P. tamariscinum in texture, and in the pellucid nature of the frond, and the 

 shape of the segments. The specimens are very uniform. 



147. P. (Eupolypodium) heteromorphum, Hook, et Grev. ; 

 caudex small short erect very villous, stipites tufted slender 

 filiform very variable in length villous as is the whole plant 

 with copious long ferruginous simj)le or stellated hairs some- 

 times quite shaggy, fronds mendsranaceous simple or several 

 times dichotomously forked from 4-6 inches to a foot and 

 more in length sometimes regularly bipinnate and then they 

 are 4-5 inches in diameter, brandies whether forked or bi- 

 pinnate are j-f inch in diameter pinnated with rather dis- 

 tant pinnae from 2-3 lines to t, an inch long distant sessile 

 and decurrent or subpetiolate generally obovato-spathulate 

 and entire or oblong obtuse and more or less pinnatifid, 

 costule and rather distant simple veins manifest, sori 1-6 on 

 a pinnule subglobose terminal on the veins and nearer the 

 margin than to the costule. Hook, et Grev. Ic. Fil. t. 108. 

 Metten. Polyp, p. 48. 



Hab. Andes of Ecuador, alt. 12,000-15,000 feet, growing in large patclies 

 over the face of the dripping rocks, Jameson. New Granada, Linden, n. 75, 

 Purdie, Uartweg, n. 1517. Mexico, Schiede, Andrieux, n. 46, Liebmann, Linden, 

 n. 51, Galeotti,n. G, 2()1.— I must refer to Dr. Greville's admirable figine of this 

 Fern, in Ic. Fil., for some of the variations of this most singular and hetcromor- 

 phous species. 



148. P. (Eupolypodium) eriopliorum, Hook. ; caudex as 

 thick as a crow's quill repent densely clothed with setaceous 

 castaneous scales, stipites numerous approximate 4-5 inches 

 long black patently villous, fronds 2-2 1 inches long cordately 

 five-angled deeply three-lobed obtuse bi-tripinnatifid densely 

 villoso-tomentosc tawny beneath, middle lobe triangular pin- 

 natifid, the segments oblong obtuse entire or lobulate, lateral 

 lobes semiovate lower half pinnatifid, veinlets forked, sori 

 marginal on the apex of the veinlets. Hook. Ic. Fl. t. 991.
