HYPOLRPIS. 61 



lenso, J. D. Hooker, and others. Luzon, Cuming, n. 118 and 233 (stipes 

 and lachis bruwner). — /3. New Zealand; Wahaki, Dr. Sinclair. Bay of 

 Islands, J. D. Hooker. — y. Between Cape Brett and VVangarei Bay, East 

 Coast, N. Zealand, near the coast ; scarce, and found nowhere else. (Tab. 

 XC. A.) Rev. W. Colenso, n. 420. — Our specimens most in accordance with 

 Forster's plant are those from the Coral Islands (some without any habitat 

 jriven) in the late Capt. Carmichael's collection, and some of Dr. Hooker's 

 from New Zealand. Forster's original plant is, however, rather more slen- 

 der and the pinnae and pinnules more erect and attenuated than any we 

 possess : and it must be confessed that the difllerence between that and our 

 var. y. strike the eye, at first sight, as being very considerable. Certainly 

 no ligure of any small portion of a plant will give an accurate idea of the 

 species itself, still less of the varieties. Yet from New Zealand alone, I 

 possess specimens which almost satisfy me that I am correct in making va- 

 rieties rather than in forming species. Even of the most remarkable vari- 

 ety, that of our valued friend Mr. Colenso, I find a specimen marked " N. 

 Zealand, " from Capt. Carmichael's herbarium, which seems to unite 0. with 

 y. — We have received this and other species from N. Zealand as " Chei- 

 lanl/ies amhigua, A. Rich." : and we are not sure but this is the C. amhigua 

 of Allan Cunningham, jndging from a specimen we have received from Mr. 

 Heward. Richard expressly says of his C. amhigua, " Au premier abord, 

 et quand les fronds sont bien developpees, on pourrait la prendre pour une 

 espece de Polypodium. En effet les sores sont arrondis, distincts et nus, 

 correspondant a chacune des dents ou divisions des lanieres. Mais si Ton 

 examine ces frondes avaut leur epanouissement, on voit alors que les divi- 

 sions sont recourbees en dessous, et qu'elles recouvrent completement chac- 

 un des sores, en lui formant une sorte d'involucre, sans neanmoins changer 

 de nature.'' (Voy. de 1' Astrolabe, Bot. i. p. 84). — All this seems to point to 

 a Polypodium common in New Zealand, frequently confounded with our 

 H. temdfolia, for its general aspect is very similar, probably identical with 

 the New Holland Polypodium rugulosum. La Bill., and also with Cheilan- 

 thes viscosa, Carm., of Tristan d'Acunha, (Polypodium, Spreng.) Li an old 

 state of these, the teeth or lobules of the pinnules may be seen to form an 

 arch over the sori without altering in texture : this however is very diffe- 

 rent from the involucre of Hypolepis : as may be seen in a portion we have 

 represented of the var. y. of the present species. (Tab. XC. A.) — There is 

 probably some error in this species being called by Forster, and others after 

 him, an "arborescent" fem. 



2. H. Guianensis, K\. ; " rhizoraa .? frond tvipinnatifid 

 ovato-acuminate, rachises and stipes yellowish unarmed 

 subviscoso-pubescent, pinnae broadly lanceolate acute, secon- 

 dary pinnae lanceolate falcate obtuse sparingly puberulous on 

 both sides, beneath bright above brownish green, pinnules 

 lanceolato-oblong subfalcate rounded at the apex obsoletely 

 pinnalifido-lobale sessile." Klofzsch, in Linnaa, 1847, j?. 3:39. 



Hab. British Guiana, R. Schomburgk, n. 1 166. — " Frond 2 feet long. 

 Superior pinnae 3 lower ones 6 inches long attenuate confluent towards the 

 apices." — Of this species I know nothing, and nothing is said of the sori 

 and involucres.
