2. Aspidifm.] 2. POLTPODIACHJS. [4. Humata. 



late with generally free included veinlets in the areoles. 

 Indusium peltate or somewhat reniform. 



1. A. cicutarium, Sw. 



A tufted fern with the fronds often 2|-3 ft. by 1 ft. 8" 

 deltoid, pinnatifid, or pinnate below with the pinnae deeply 

 pinnatifid, rarely 2-pinnate. Sori at the ends of the free 

 included veinlets. Indusium attached by the center, usually 

 with a sinus. 



Shady banks, common. Fr. Nov.-Jany. 



Stipes deep chestnut brown flattened, with few oblong scales. Pinna 

 pubescent above and on th9 nerves beneath, often much produced below 

 pinnatifid with the lobes crenate. 



3. OdontOSOria, Presl. (Stenoloma, Fee.) 



Sori quite terminal on the lobes of the frond, the indnsium 

 fused at the base and sides to the lobe, and, with it forming 

 a terminal cup containing the sporangia . L. several times 

 pinnate with veins forked free. Stipes not articulate to the 

 rhizome. 



1, 0. chinensis, £• Syn. Davallia chinensis, Sw. ; Steno- 

 loma chinensis, Sw. 



A very beautiful fern with 3-pinnate fronds 2-3J ft. long, 

 the pinnules cut into linear-obcuneate forked lobes bearing 

 the sori on their expanded tips. 



Along streamB in Saranda. Fr. April, 



Rootstoch tufted with shining-brown scales, stipes glabrous polished 

 8-18" ; pinna 2^-4" distant alt. with the rachis flattened and grooved 

 above. Apex of lobe minutely toothed. The cups often geminate. 



To the closely allied genus Humata belong two ferns, vis, H. 

 immersa, Wall, and H. pulchra. Don. with widely creeping rhizomes 

 and thin 3-pinnate frords. The indusium is of similar shape to the last, 

 but is not fused at the sides, and the sori are intra-marginal. The 

 segments of the frond in H. immersa are roundly lobed with the lobes 

 •renate above in H. pulchra, the lobes are narrow lanceolate.
