Stipes provided above with 2 rows of glands (linear aerophores). 



(3d) D. Icptolcpia, r. A. ». K., in Bull. Btz., 1916, XXIII, 12. 



Stipes + 90—100 cm. long, slender, blackish, scaly, deciduously 

 ferrugineo-furfuraceous and acutely muricate near the base, otherwise 

 red-brown, naked (glabrescent ?), minutely verruculoso-asperulous and 

 provided above with two rows of pale-yellow-brown longitudinal streaks 

 (long-linear aerophores); scales erected, red-brown, linear-subulate, entire. 

 Fronds 3-pinnatifid, the rachis similar to the upper part of the stipe at 

 least in the lower part. Pinnae sessile or nearly so, horizontal or spj'ead- 

 ing, lanceolate-ovate or elongate-oblong, + 27 V-, — 30 cm. long, 10—12 

 cm. broad at the middle, more or less abruptly acuminate, the rachis 

 rather loosely tomentose above, deciduously chaffy beneath, narrowly 

 winged in the upper part, the hairs long, rufous, the squamules brown, 

 flattish, sublanceolate. Pinmilae to 4: 20 on a side below the terminal 

 one; terminal pinnulae long- triangular, deeply pinnatifid at the base with 

 entire to toothed lobes, the apex bluntly serrate-dentate; lateral pinnulae 

 spreading; largest pinnulae sessile or subsessile, linear-sublanceolate, to 6 

 cm. long, + l'/2 cm. broad at the truncate base, deeply pinnatifid (pinnati- 

 partite), narx-owed gradually towards the subabruptly acuminate apex, the 

 acumen blunt, entire or subentire, sparingly bluntly serrate-dentate at 

 the base; lower pinnulae more or less reduced. Segments subcontiguous, 

 spreading, linear-oblong, straight or subfalcate, the largest to l^j,^ mm. 

 long by 3 mm. broad, blunt or rounded at the apex, entire or indistinctly 

 subrepando-crenulate. Texture rather coriaceous; surfaces naked; costae 

 brown-hairy above, deciduously squamulose below, the lower squamules 

 flattish, sublanceolate, the higher more or less bnllate ; costulae naked
