CIBOT1UOT, Haulfm*. 



< i hot i 11 in barometz (Baranetz), ./. Sm„ Journ. of 

 Bot,, I, 437; Christ, Philipp. Journ. Sci., II, C, 117. 



Christ recognizes four distinct forms of Cibotium, which 

 probably may be regarded as varieties, and from an examination 

 of the material of the Buitenzorg Herbarium I distinguish still 

 two forms more : 



Var. setosum: Like var. sumatranum (C. sumatranum, 

 Christ, l.c, 118), but the rachis, costae and costulao densely clothed 

 with pale-brown or yellowish bristles spreading in various 

 directions and leaving the rachis subasperous when they fall. 

 Sori 1 or rarely 2 on each side, occupying the base of the seg- 

 ments, remote from the cost»; indusium fulvous. — Locality not 

 mentioned, but very probably malayan. 



Var. lampongrense : Like var. Cumingii (C. Cumingii, 

 Kse, Christ, l.c, 118), but the ultimate segments falcate, bluntly 

 crenato-serrate. Costae and costulse copiously (not densely), but 

 deciduously furfuraceous, the tomentum loose, pale-brown, inter- 

 mixed with long, firm, straight or crisped, bristle-like, dark-brown 

 hairs. Sori rather close to the costse, less oblique; indusium 

 brown, not pruinose. — Sumatra (Teysmann).

Frondes + 50—100 cm. longaa, apice dichotoma?, caeterum 

 pinnataa, rachide indumento deciduo, tomentoso vel furfuraceo ves- 

 tita, pinnis 2 — 3-jugis, erecto-patentibus, supenoribus dichotomis, 

 infimis pinnatis, apice dichotomis, pinnulis dichotomis, furcis 

 omnibus foliaceis, profunde pinnatifidis, laciniis lineari-oblongis, 

 apice obtusis, crenatis, subcoriaceis, subtus plerumque glaucis, costa 

 tomento deciduo tecta, 1 — 2 cm. longis, db 2 m.m. latis, laciniis 

 infimis plerumque reductis, suborbicularibus, ramulis ultimis acu- 

 minatis, apice grosse dentatis.
