 Japan, Mr. Babington. — An extremely distinct and well-marked species, of which 

 however our var. ;8 is a very remarkable variety. 



23. Pt. (Eupteris) Dalhousice, Hook.; tall 2-3 feet and 

 more high, frond ample 1-2 feet subcoriaceo-membranaceous 

 glossy bi- tri- below subquadripinnate, pinnce and pinnules 

 all remote, superior pinnee simple (undivided) and pinnules 

 all linear-sublanceolate very much elongated acuminated and 

 serrated remarkably alato-decurrent on the rachis, lower pri- 

 mary pinnsB not decurrent petiolate falcate (lowest pair some- 

 times bipartite) the upper margin entire (rarely with one seg- 

 ment) the lower pinnate (or pinnatifid) with 5 or 6 (more or 

 less) long pinnae decurrent so as to form a very broad winged 

 rachis, veinlets simple or forked, involucres subintramarginal 

 narrow membranaceous continuous along the rachis rarely 

 reaching the acuminated apices, stipes very glossy and as 

 well as the firm prominent costa bright glossy tawny or pur- 

 ple-brown. (Tab. CXXI. A.) 



Hab. Penang, Lady Dalhousie. Java, Thomas Lobb, n. 206. — It is im))0ssible 

 to do justice to this large and beautiful species in the small space allotted to our 

 figures. It is evidently allied to Pt. semipinnata, L., having the majority of 

 the pinnae again pinnated, or, if the term is preferred, pinnatitid only on the lower 

 side ; but is at once distinguished from that by its great size, by the very remote 

 superior pinnje, and by the great length of all the segments. In one of our spe- 

 cimens the lowest pinnse are bipartite, and each segment represents as it were a 

 frond in its structure, the ajjcx having the simple pinnae on both sides, and the 

 lower pinna; being unilaterally divided. Mr. J. Smith has marked the specimen 

 in bis herbarium, from Java, as Pt. venulosa, Bl. ; but whatever uncertainty there 

 may be about that species, it cannot be our present one, for Blume and Agardh 

 could not have overlooked the peculiar division of the pinnae, so much like that 

 of Pt. semipinnata. 



24. Pt- (Eupteris) Griffithii, Hook. ; a foot and more high 

 and slender graceful, caudex none, roots of tufted fibres, 

 frond ovato-lanceolate submembranaceous pinnate, upper 

 pinnae simple 2 or 3 of the lower pairs again pinnated simple, 

 pinnae and pinnules exactly linear \ an inch to an inch and 

 a half long obtuse mostly opposite everywhere entire sessile 

 with the base adnate and decurrent so as to form a narrow 

 wing to the rachis, lowest pinnules of the inferior pinnae 

 sometimes again divided, terminal pinnule always elongated, 

 veins distant once forked, veinlets divaricating, sori conti- 

 nuous, involucres subintramarginal membranaceous not reach- 

 ing to the apex, stipites slender longer than the fronds stra-
