PTERIS. 179 



nor could justice be done to such figures except they were executed on a large 

 scale. — If the Author of the present work has few or no authentic sjjeciniens or 

 figures to refer to for the original species, he is fortunate in having the advan- 

 tage of possessing in his herbarium authentic specimens of the majority of those 

 described by Agardh iu his well-known ' llecensio Spccicruni Generis Pteridis,' 

 and which are of no small value on the present occasion.) 



37. Pt. (Eupteris) longipinnula, Wall. ; tall, frond ample 

 oblong-ovate coriaceo-submembranaceous shining, pinnae 

 large (often a span long) broad lanceolate pectinato-pinnati- 

 fid rarely bipartite, segments spreading nearly horizontally 

 linear-oblong subacute entire, terminal one more or less 

 elongated, lowest pair unequal short decurrent into a short 

 petiole, involucres very narrow extending from the sinus 

 nearly to the apex, veins prominent forked from their base, 

 stipes elongated (2-3 feet long) and as well as the rachis and 

 costa usually of the same colour as the frond (rarely brown) 

 glossy. (Tab. CXXXIV. A.)— Wall. Cat. n. 108. Ag. Sp.

Hab. Mountains of Penang, Wallich ; Labuan (with only five pinnae), Thos. 

 Lobb; Bhotan, Griffith; Nepal, Sikkim, 2-4000 feet, Dr. Hooket^; k%%dm, Simons; 

 Khasia, 2-3000 feet, and Sylhet, Drs. Hooker and Thomson; Cotalam, Madras, 

 G. Thomson, n. 139, in part. — A large species, several feet high, including the 

 stipes, the pinnse having very much the general appearance of those of the next 

 group, but here the pinnae are generally all uniform, that is, the lowest pair not 

 again divided, and this is the case with all our numerous specimens save one, 

 where a forking takes place. The species too is remarkable for the short, lower, 

 unequal and decurrent segments of the pinnae, and the generally green colour of 

 the stipes, rachises, and costaj, and for the conspicuous venation, the veins rather 

 distant and forked to the base. Agardh, under Pt. longipinnula, in a note, makes 

 allusion to the Pt. attenuafa, Sw. (not Blurae), and of which a segment of a 

 pinna is figured by Presl in his Tent. Pteridograph. t. 5. f. 18. The latter author 

 says of it, " Pt. arrjuta atfinis, sed pinna; infimae non partita; sed indivisaR." But 

 all is doubtful about that plant, and the two authors had probably different 

 species in view. 



38. Pt. (Eupteris) quadriaurita, Retz; caudex short erect, 

 fronds often large ovato- or cordato-ovate acuminate coria- 

 ceo-membranaceous pinnate, pinnee 5-21 or more mostly- 

 opposite sessile lanceolate deeply pinnatifid (so as to leave a 

 narrow wing to the rachis), segments oblong obtuse mostly 

 entire, terminal ones caudate, lowest pair of pinna3 (some- 

 times more) bipartite or rarely bearing 2 or 3 pinnje on the 

 lower side, lowest segments subdecurrent on a short petiole, 

 veins forked basal ones terminating at or above the sinus, 

 involucres occupying nearly the whole length of the margin 

 of the segments, stipes elongated stramineous or brown 

 smooth and glossy or scabrous. (Tab. CXXXIV. B.) — Betz,
