<);iliu, quite accord with those from N. Holland and other islands of the South 

 Seas. 



5. D. connexa, Kze. ; "frond linear-lanccoIate acuminate 

 subcoriaceous glaljrous pinnated pinnatifid towards the apex, 

 pinnae sessile remote alternate patulous linear-oblong obtuse 

 serrulate decurrent" (more or less), " the sinuses broad sub- 

 angulate, inferior ones auriculate, stipes and rachis purple- 

 black glabrous." Kze. in Schk. FiL Suppl. i. jj, l\. f. 6. —

Ilab. Pitcairn's Island, Cuming, n. 1371 (the authority for the species); frond 

 larger than Dr. Kunze's figure, 2 feet long independent of stipes, and G iiiclics 

 wide; Mathews, and Otaheite, Cuming, n. 1413 (these quite correspond witli 

 Kunze's figure). Coral Isles, Beechcy, the same form as Cuming's 1374. Uaoul, 

 or Sunday Island, Milne and M'Gillivray : the same state as that last mentione<I ; 

 but some of Milne's specimens are very luxuriant, and have segments and piniuc 

 6 inches long, sometimes, hut rarely, partially pinnatifid. In this the sori are in 

 two rows. — The majority of my specimens are larger than the specimen which is 

 figured l}y Kunze, which last is, I fear, not ditferent from our I), media ; and I 

 fear, too, our largest specimens should be referred to that species. All our spe- 

 cies of the genus are singularly variable. 



6. D. caudata, Br. ; roots wiry black villous with black 

 hairs, no distinct caudex, stipes slender 1-4 inches long 

 smooth or nearly so stramineous-black at the base, fronds 

 tufted subdimorphous 5-10 inches long flexuose generally 

 thin membranaceous pale-green oblong- or linear-lanceolate 

 pinnate nearly to the summit, sterile generally the shortest, 

 pinna3 elliptical membranaceous obtuse more or less acutely 

 and subpungently serrate approximate uppermost ones only 

 confluent into an oblong-lanceolate apex,yer/i/e ones longer 

 narrower more harsh and rigid, pinnae remote linear or linear- 

 attenuate truncate and subauricled at the base sometimes the 

 margin acutely and pungently dentate, inferior ones more 

 distant and sterile, uppermost ones only confluent and termi- 

 nating in a very long caudate segment, sori in a single series, 

 involucres membranaceous, rachis stramineous slender quite 

 smooth. — ^r. Prodr. p. 151. Hook. Ex. Fl. t. 25 {small, bat
