(ST) HYPOLEPIS H.-inhanli. 



Rhizome creeping, stipes imt articulate to it; fronds at least bipinnate, 

 tliiii, imhesccnt; veins free, soii iinrdly terminal, single in the sinuses, 

 piolecti'd by reflexed marginal lobes too small to rover them ["lermanently. 

 Our species is a large terri'strial fern. 



(li H. tenuifolia Uernh. Rhizome wide-creeping, densely glandular- 

 puberulent; stipe about '.iO cm. high, maroon, shining, jjuberulous like the 

 rhizome but less so; frond 50 to 250 cm. high, (piadripinnatifid ; lower 

 pinna- ovate-lanceolate, 20 to 50 cm. long; |)innuies about 10 cm. long, 

 lanceolate; pinnules of second ordei- 2 to '^ cm. long, lanceolate, c\it 

 down about to the rachis into linear-oldong. tootiied ultimate divisions, 

 lierbaceous, sparingly glandular-pubescent beneath, the rachises more so; 

 sori placed in the sinuses of the teeth or ultimate division.s. The 

 resemblance of this species to yephrodiiiDi nuinlosu))\ is most striking, 

 extending to every detail except the position and protection of the sorus; 

 and in that matter I have specimens of the later species with the sorus 

 nearer the margin iliaii usual, witli the tip of the tooth somewhat curled 

 upward, strongly suggesting that these two ferns, apparently representing 

 widelv separated groups, may really be the same.

(38) CHEILANTHES Swartz. 



Rhizome short, scaly; fronds at least bipinnatifid; veins free; sori ter- 

 minal on tlieir thickened ends, usually confluent at maturity, protected at 

 first or permanently by the infolded and modified (membranous) margin of 

 the frond. Terrestrial ferns, chiefly of warm and dry countries.

 firm when dry; indiisjum interrupted.
