ONYCHIUM. 123 



Capemtc of Kaiilfuss was not of African orifj^in. Kunzc, in ' Linnaja,' x. 

 /. c. observed tliat " he had seen a specimen of Kaulfuss' O. Capeiue in 

 Roenier's Herbarium, found by Thunberpf," and, afterwards, havinff ascer- 

 tained that it was from Japan, and in reality Thunberg's Trichomanes Ja- 

 ponicitm, he very properly restored that specific appellation. It is now a 

 question whether our O. lucidum, like many other n(trthern Indian forms, 

 may not extend its range as far as Japan. Thunberg's description, brief as 

 it is, would seem to confirm such an opinion. " Frons supra decomposita 

 glabra, stipite torto sulcato. Pinnulae ultimae acuta; subtrifidae. Fructifica- 

 tiones solitaris in ultimis laciniis ; membrana tegens tenuissiraa alba." 

 Thunb. l. c. 



4. O. angustifoUum, Kunze ; " fronds bipinnate, pinnules 

 linear acuminate sessile entire and as well the rachis gla- 

 brous." H. B. K. Kunze, in Schkuhr, Fit. Sitppl. ii. p. II. 

 Cheilanthes anguslifolia, //. B. K. Gen. et Sp. Am. i. p. 17.

 Willd. Suppl. (according to Sprengel). 



Hab. Mexico, on the Mountain Jorullo, at between 3000 and 4000 feet 

 of elevation. — " Fronds 4 inches and more long, bipinnate ; pinnas alter- 

 nate, 2 inches long. Pinnules linear, acuminate, sessile, entire, glabrous, 

 an inch and a half lo two inches long, scarcely a line wide, lower ones 

 sometimes bipartite, middle nerve prominent beneath, naked. Universal 

 and partial rachises glabrous, naked, somewhat winged, greenish. Stipes 

 8 inches long, naked, nearly terete, castaneous, .shining. Sori marginal, at 

 length confluent. Sporangia cinnamon-brown. Indusium continuous, 

 arising from the margin of the frond, fimbriato crenate, diaphanous, gla- 

 brous. Perhaps a species of Pteris." — I am not acquainted with this plant, 

 which Kunze refers to Onycliium ; but I am not aware that any further 

 information is given respecting it, beyond what I have here copied from 

 Humboldt. 



5. O. strictum, Kunze ; caudex 2 — 3 inches long oblique 

 rather stout nodose throwing out wiry roots more copiously 

 from the upper extremity, stipites numerous partially scaly a" 

 span to a foot long crowded from the apex of the caudex and 

 as well as the slender rachises pale straw-colour glossy, fronds 

 a span long submembranaceoiis green glabrous opaque ovate 

 decompoinidly pinnatisected, the segments all very narrow 

 and acute opposite entire or bi-trifid subcuneate, tertiary 

 rachises winged : the fertile laciniaj are a little larger and 

 wider sharjaly acute bi- or trifid beyond the fructification, 

 bearing the sori on the disk short linear- oblong nearly while.

Hab. St. Jago de Cuba, on Mount Leban, Linden, n. 1870. — This is a 

 very distinct and well marked species, and with all the characters of Ony- 

 chium, which is thus found in the New as well as the Old World. The cau- 

 dex or rhizoma of my specimen is singularly nodose or tuberculated, and 

 one that apparently elongates upwards and bears the fronds altogether 

 from the extremity. It is remarkable for the great length of the stipites in
