divided, they are more acute and acuminate. Kunze and Moritz and 

 Poeppig describe the plant as attaining a length of 20 feet ! The fine 

 specimen for which I am indebted to Mr. Sonder is 8 feet long. 



13. H. nigrescenn, Hook. ; fronds ample straggling sub- 

 niembranaceous 3-4-pinuate glabrous brownish black when 

 dry opaque, primar}- pinna3 distant often opposite very patent 

 ovate acuminate, secondary and tertiary pinnae rather short 

 oblong moderately acuminated, ultimate pinnules or segments 

 oblong obtuse pinnatiiid, lobes oval obtuse entire bearing a 

 small single sorus on the anterior margin, involucres very 

 small squamiform, stipes and principal rachis flexuose gla- 

 brous polished dark brown aculeated. (Tab. XC. C.) H. re-

Hab. Jamaica, Wilson, Wiles, Purdic, {Herh. Hook, et J. Sm.) Cara- 

 cas, Linden, n. 5 and 6. Luzon, Cuming, n. 271. — In words or even in a 

 small figure it is scarcely possible to define the characteristic distinctions 

 of this plant, which in many respects resembles //. repens. Mr. J. Smith in- 

 deed published the Philippine Island plant as such, and stated that it exactly 

 accorded with the ])lant of that name from Jamaica. This is so far true that 

 he rightly considered the plant of Cuming identical with what he and I 

 independently of each other had considered the //. repens ; that is, a Ja- 

 maica Hijpolepis which accorded with the ordinary description of the H. 

 repens. As already stated, however, I have adopted another form of Hy- 

 polepis, viz., that of Sieber and Kaulfuss, as the true H. repens ; and the 

 present species is at once, by the eye, distinguishable from that, by its more 

 lax habit, more membranaceous texture, shorter pinnae, and much shorter 

 ultimate pinnules, with fewer and smaller fructifications. The aculeated 

 stipes and rachis are the same in both. 



14. H. anthriscifolia, Pr. ; fronds ample tripinnate hairy 

 on the midrib and veins beneath tender green membranace- 

 ous, primary pinnae oblong ovate acuminate, secondary ones 

 broad oblong acuminate, pinnules linear-oblong subfalcate 

 deeply pinnatifid, lobes small uniform entire or one- or two- 

 toothed bearing a solitary sorus in the inner margin, involu- 

 cres small squamiform, stipes and rachis rich yellow-brown 

 glabrous asperulous. (Tab. XCV. A.) Presl, Tent. Pterid.

 S. Africa, Villette, Miller, Dr. Alexander, DrSge, Zeyher, n. 4633. — A very 

 elegant and delicate species, the pinnae and pinnules divided and cut with 

 great regularity. I have the good fortune to possess specimens from Bour- 

 bon, gathered there by Capt. Carmichacl. The Mauritius specimens are
