 inargiued." Desv. I. c. p. 318. — Hab. E. Indies. 



8. CiBOTiUM, Kaulf. 

 Pinonia, GaiuUch. 



Sort at the very margin and projecting from it, pointing 

 downwards, always from tlic apex of a vein. Involucre sub- 

 globose or reniform, coriaceous or horny, 2-valved, generally 

 unequally so, outer valve not formed of the substance of the 

 frond, inner one smaller and operculiform. Receptacle a lit- 

 tle elevated. Capsules stipitate, with a nearly complete ring. 

 — Tropical or subtropical Ferns of the northern hemisphere, 

 inhahitincj the Sandwich Islands, the Philippines, Assam 

 and Mexico, arborescent in C. Chamissoi and C. Schiedei, 

 ( perhaps in others) ; fronds hipinnate. Veins simple or once 

 or twice forked. Hook. Gen. Fil. tab. 25. 



1. C ghmcum, H. et A. ; fronds bipinnate glabrous very 

 glaucous beneath, pinna> linear-oblong acuminated into a 

 long narrow seirated point deeply pinnatifid to the rachis 

 often pinnate at their base, segments oblong falcate ra- 

 ther acute crenato-serrate especially at the apex, involucres 

 coriaceous numerous 6 — 12 on each segment or on each 

 ultimate pinnule rather small tawny, the valves unequal, in- 

 nermost one narrow and elongated, veins once or twice forked, 

 rachis and costa quite glabrous. (Tab. XXIX. A.) — Hook,

Hab. Sandwich Islands, Mr. Menzies. Lay ^ Collie in Beechey's Voy. 

 — Discovered so long ago as 1807 by the venerable Menzies, and described 

 by Sir J . E. Smith in Rees' Cyclopaedia. Other species have doubtless 

 been confounded with it. Pinnae a span long, narrow, much attenuated, 

 subcoriaceous, very glaucous beneath, at the base often again pinnated, 

 veins once or twice forked, rarely if ever simple. I have only seen speci- 

 mens from Menzies and Beechey's voyage. Mr. Menzies had distinguish- 

 ed this and an allied species in his herbarium under the name of Hiatea, 

 and remarked that though now arranged (by Smith) under Dicksonia, yet 

 they did not agree with that genus. 



2. C. yhiucescens,Kzo.; fronds bipinnate, pinna? naiTow 

 or linear-oblong much acuminate caudate glaucous beneath 

 pinnatifid nearly to the rachis, segments oblong acute ser- 

 rated subfalcate lower ones sometimes distinct glabrous or 

 slightly arachnoid, involucres solitary one on each side the 

 base of the segments small subcoriaceous glaucous reniform, 

 the valves nearly equal and both transversely oblong convex.
