upper ones simple, the lower forked. Sori in long rows close to the 

 midrib. Involucre large, fragile, breaking up irregularly. Receptacle 

 pilose. 



This, again, is closely allied to C. canaliculata, but differs by its 

 quadrately-crenate free pinnules and pilose under surface. 



33*. Cyathea discolor, Baker, n. sp. Fronds ample, tripinnate. 

 Pinnae oblong-lanceolate, 1-1 £ foot long, 7-8 inches broad. Pinnules 

 lanceolate, sessile, the fully-developed ones 3^-4 inches long, §-f in. 

 broad, cut down to the rachis into close, adnate, ligulate, obtuse lobes 

 l\ in. broad, subentire, or the lowest crenated. Texture membranous. 

 Upper surface green, naked ; lower white, with a few scattered scales 

 on the ribs. Rachises pale brown, tomentose above, naked below 

 with a few scattered linear paleae. Veins of developed tertiary seg- 

 ments 9-10-jugate, fine, not raised, the lower ones deeply forked or 

 even trifid, the upper ones simple. Sori small, costular, confined to 

 the lower half or third of the segments. Involucre membranous, per- 

 sistent, breaking up irregularly. Receptacle naked. 



Reminds one strongly of the well-known New-Zealand C. deal- 

 lata ; but the white is much deader, the texture less coriaceous, 

 and the involucre larger and deeper. 



Hemitelia Melleri, Baker? 



Only doubtful on account of the absence of fruit. 



64*. Alsophila bullata, Baker, n. sp. Frond ample, tripinnate. 

 Pinnae oblong-lanceolate, 15-18 in. long, 6-7 inches broad. Pinnules 

 lanceolate, subsessile, 3-4 in. long, f-g in. broad, cut down to the 

 rachis into crenate, patent, ligulate, obtuse tertiary segments i in. 

 broad, the lower ones free, with a space equal to their breadth be- 

 tween them, the upper ones adnate and closer. Texture membranous. 

 Both surfaces green. Rachis of the pinnae dull bfown, scabrous with 

 minute furfuraceous brown scales ; of the pinnules tomentose above, 

 of the pinnules and tertiary segments below densely clothed with mi- 

 nute bullate scales. Veins 6-8-jugate in the tertiary segments, one to 

 each lobe, erecto-patent, deeply forked. Sori about 15 to a segment, 

 minute, placed at the forking of the veins rather nearer the midrib 

 than the edge. Receptacle densely pilose. 



A well-marked species, recognizable amidst the crowd of tripin- 

 nate Alsophilas by its deeply crenated tertiary segments and 

 copious minute bullate scales of the ultimate rachises. 



64*. Alsophila vestita, Baker, n. sp. Frond ample, tripinnate. 

 Pinnae oblong-lanceolate, 12-15 in. long, 4-5 in. broad. Pinnules 

 lanceolate, j~f in. broad, cut down to the rachis into close ligulate 

 obtuse, distinctly crenated tertiary segments i in. broad, the lower
