Hab. Philippine Ishinds, Cuminff, n. 123. — This is, in many respects, 

 allied to C. glaucum, but distinj^uished by its simpler veins and by the 

 involucres, which besides being of a different form and texture, stand sin- 

 gly, one (very rarely two) on each side at the base of each segment, thus, 

 as i>lv. J. Smith remarks, forming a long parallel line on each side the costa 

 and a little remote from it. They are by no means corncjous and tawny, 

 but rather coriaceous, approaching to membranaceous and glaucous, broad- 

 er than long, reniform, the two valves nearly alike in size and form ; and 

 the same characters exist on various specimens. Our cultivated ones from 

 the Birmingham Botanic Garden, which are, I believe, identical with the 

 C. glauccscens, Kze., are similar to Mr. Cuming's from Luzon, proba- 

 bly the native country of the garden ])laut, which has by some, but with- 

 out sufficient authority, been supposed to be the " Tartarian Lamb '' of 

 Loureiro. 



3. C. Assamicum, Hook.; fronds bipinnate, pinnae oblong- 

 lanceolate very mnch attenuated caudate glaucous beneath 

 deejily pinnatifid almost to the rachis the lower segments re- 

 mote (but united) all of them linear-oblong very acute sub- 

 falcate serrated, involucres subcoriaceous several (4 — 6) on 

 each segment pale brown the valves unequal inner one nar- 

 rower, rachis glabrous, costa with arachnoid appressed hairs, 

 veins simple or rarely forked. (Tab. XXIX. B.) 



Hab. Assam, Mrs. Mack. — Allied to C. glaucum and glaucescem, differing 

 from the former in the more simple veins and less coriaceous involucres, 

 and from the latter in the different form and texture and unequal valves 

 of the involucres. 



4. C. Chainissoi, Kaulf. ; arborescent, fronds bipinnate, 

 pinnae lanceolate acuminate subcoriaceous not anywhere glau- 

 cous glabrous or beneath (especially on the rachis and costa) 

 clothed with more or less copious arachnoid hairs pinna- 

 tifid f or f down to the rachis, the segments ovate obtuse 

 bluntly serrate, involucres generally copious (G — 12) rather 

 small very horny glossy tawny the valves unequal, inner one 

 narrower, veins sunk (not prominent) dark-coloured simple or 

 forked. — A'a;/7/: Fnitm. Fil. p. 230, /. l,/'. 14, {April 1824). 

 Pinonia splendens, Gaud, in Ann. Sc. Ndt. Dec. 1824, and 

 in Freycin. Voy. p. 370, /. 21. 



Hab. Oahu, Chamisso, Gaudichaud, Barclay, Macrae. — Truly distinct 

 from all the preceding and from the following species. It is the species on 

 which the genus Cibotium was founded by Kaulfuss, and Pinonia by Gau- 

 dichaud : with the figures and descriptions of both of which it entirely
