68 HYPOLEPIS. 



tertiary ones or pinnules and primary lobes subovate rather 

 oblique entire or pinnatifid, involucres (young) very small si- 

 tuated at the inner margin of a lobe or lobule membranace- 

 ous, stipes and primary rachises deep purple-black and as 

 well as the secondary rachises and costa clothed with rusty 

 hairs. — Cheilanthes Bergiana, "■ Schlecht. Adumbr. Fit. p. 51,

Hab. South Africa, Eckloji, Drige (in Herb, nostr.), Krehs. — I regret 

 that, as before observed, my copy of Sclilechtcndars ' Adumbratio Filicum ' 

 does not extend to p. 51 ; and I have no access to a description or authen- 

 tic specimen or figure, unless Drege's specimen marked " Cheilanthes Ber- 

 giana, Sclilecht.'' may be considered so. This too I am sorry to say is but 

 the lower portion of a young frond, with a stipes scarcely more than a span 

 long. Judging from this it is distinct from any Hi/polepis I am acquainted 

 with: in the form of its ultimate lobes and pinnules showing some affinity 

 with H.repem; but in little else. Kunze observes, "E distinctis.simis 

 generis ! Specimina nostra triplicato- tri- s. quadripinnata inter longitudi- 

 nem 4 et 16 pollicum variant. Caudex repens, radicibus elongatis ramulo- 

 sis. Quoad reliqua v. descriptionem Schlechtendalianam." 



18, H. rugulosa ; fronds rather large tripinnate rigid co- 

 riaceus opaque dark brown when dry slightly hairy beneath, 

 ramification much divaricated, primary pinnae ovate acumi- 

 nated, secondary broad-lanceolate moderately acuminated, 

 pinnules oblong rather obtuse deeply pinnatifid the segments 

 entire or more or less incised, sori transversely oblong one on 

 each lobe, the lobe obliquely reflexed forming the involucre 

 becoming thick and hard at the base the apex scariose, stipes 

 and very flexuose primary rachis red-brown glossy slightly 

 viscido-hirsute and rough scarcely aculeolate. — Pteris rugu-

Hab. Otaheite, Nelson, Banks (in Herb. Banks.), D'Urville (in Herb, 

 nostr.) ; in mountain woods, rare, Bidivill. New Caledonia, Labillardi- 

 ere. — A most distinct and well marked specie-s with a very zigzag main 

 rachis to the frond and the latter beautifully cut into small lobes and teeth. 

 Labillardiere's figure of the entire plant is excellent, not so the magnified 

 figure and the fructification, which latter is represented too much like that 

 of a Pteris. Guillemin judged, but from the figure alone, for he does not 

 appear to have seen the plant, that it was not a good Pteris, but rather an 

 Allosorus or a new genus. It enters nevertheless well into Hi/polepis, hav- 

 ing quite the habit, although the involucre is of a harder and thicker texture 

 at the base than in any other species : its margin however is thin and mem- 

 branaceous, and is curved down upon a comparatively small number of 

 capsules that form the sorus.
