PTERIS. 169 



21. Pt. (Eupteris) distans, J. Sni. ; H-2 feet high, caudex 

 none, roots tufted fibrous, frond a foot or more long submem- 

 branaceous lanceolate pinnate, superior pinnoe numerous 

 linear-oblong subfalcate approximate and most of them con- 

 fluent at the base spinuloso-serrated at the apex, the rest of 

 the pinnae again pinnated very distant, pinnules linear-oblong 

 approximate and often confluent at the base, terminal pin- 

 nule very long linear caudate spinuloso-serrate, veinlets 

 forked, involucres slightly intramarginal membranaceous not 

 reaching to the apex of the pinnules close-pressed, stipes 

 short and rachis tawny or brown scabrous. (Tab. CXXIV.

Hal). Luzon, Cuming, n. 410. — A very remarkable, and assuredly quite distinct, 

 species ; nor have we seen any specimens which show much affinity to any known 

 species : the several samples we have seen of Mr. Cuming are uniformly the 

 same. Perhaps instead of considering the frond as bipinnate, it would be more 

 correct to describe it as pinnate, with the pinnre deeply piiinatifid (pectinatedly 

 so) ; thus, what we have called the numerous, closely-placed, and at the base con- 

 fluent, pinnules, would be the lobes or segments of long piunatifid pinna, with its 

 terminal lobe narrow-caudate, and the inferior pinnated pinme would in like man- 

 ner be pinnatifid pinnae, with few segments, and with the terminal lobe elongated, 

 but in some of our specimens these segments are quite free and independent of 

 the rest, and in themselves true pinnules. 



22. Pt. (Eupteris) semipinnata, L. ; 1-3 feet high, caudex 

 stout creeping villoso-squamose fibrous-rooted, fronds broad- 

 lanceolate acuminate submembranaceous pellucid pinnate, 

 superior pinnae approximate linear-oblong sessile at the base 

 adnate and decurrenti-confluent, lateral ones distant subpe- 

 tiolate semi-ovate, superior margin entire, inferior subpecti- 

 nato-pinnatitid (lowest pair sometimes bipartite) the extremity 

 long-caudate, the segments oblong all spinuloso-serrated in 

 the sterile fronds, linear and entire except at the apex in the 

 fertile ones, veins simple and forked, involucres subintramar- 

 ginal membranaceous often continued round the apex, stipes 

 rather stout castaneous or purple-ebeneous very glossy. —

 superior lateral pinnae pectinato-pinnatifid on both sides, 

 segments of the upper side abbreviated and gradually reduced 

 to the lowest pinnae where they are only auricled at the base 

 above.
