4. C. InsIGNIS (sp. nov.): caudice arboreo; stipite badio inermi minute ruguloso 
paleis cinnamomeis anguste linearibus spinuloso-ciliatis (poll. ad semilineam gradatis) 
dense vestito; fronde ampla bipinnata basi subtripinnata supra viridi ad costas pubes- 
cente subtus pallescente paleis cinnamomeis minutis laciniatis adspersa; pinnis oblongo- 
lanceolatis brevi-stipitatis; pinnulis utrinque 40 —50 lanceolatis acuminatis fere ad 
costam pinnatifidis, vel basalibus iterum pinnatis; segmentis oblongis falcatis obtusis 
integris vel inferioribus crenato-incisis; soris 8—14 in quodam segmento, involucris 
ochroleucis ovato-spheroideis apice mamillatis demum in laciniis irregularibus dirum- 
pentibus. — Frondes pluripedales. Pinne sesquipedales. Pinnule crebre, 3-4-poll. 
longe. Rachis cum ramificationibus minute rugulosa, paleolis ciliato-laceris conspersa. 
Involucra sordide alba, subpergamentacea, primum ovoidea, apice macula discolori 
elevata notata, state in laciniis persistentibus divisa. ( Wright, 1064.) 
5. C. minor (sp. nov.): caudice erecto brevi; stipite brevissimo inermi; rachi 
costisque tenuiter pubescentibus; fronde lanceolata a medio inferne attenuata apice 
breviter acuminata pinnata; pinnis utrinque 30-35 alternis oblongo-lanceolatis ad 
costam pinnatifidis; segmentis oblongis obtusis, supra glabris, subtus pubescentibus, 
basali inferiore majore rachi incumbente ; soris in quodam segmento 8 — 14; involucris 
cate depresso-cyathiformibus margine integris. — Frondes tri — quadripedales, supra 
medium 8-16 poll late, dehinc ad basin attenuate. Pinne subremote patentes, e 
basi latiore late lanceolate, apice crenate. Segmenta pinnarum majorum 50-70, 
obliqua, integra, infra ad costulam paleolas paucas bullatas ferentia. Venvle furcate. 
Sori costule approximati. Ab omnibus Cyatheis veris mihi cognitis frondibus minori- 
bus simplicioribusque distincta. (Wright, 949.) 
6. C. BALANOCARPA (Sp. nov.): caudice arboreo ; stipite sparse aculeato basi paleis 
angustis fuscis obsesso; fronde ampla lanceolata bipinnata utrinque ad costas venulasque, 
paleis minutis ferrugineis ciliato-laceris pilisque articulatis pulverulenta ; pinnis brevi- 
petiolatis e basi lata lanceolatis acuminatis ; majoribus iterum pinnatis, pinnulis utrinque 
40 —50 lineari-oblongis basi inferiore auriculatis dentato-serratis obtusis, dentibus venu- 
lam pinnatam excipientibus in axilla ramuli primi soriferis; pinnis minoribus pinnati- 
fidis, laciniis falcatis oblongis obtusis integris vel subdentatis, venulis furcatis in furca 
soriferis; involucro cyathiformi margine integro, sporangiis ad receptaculum cylindricum
