pinnas more narrowly pointed. This and the two next are distinguished from the rest 

 of the group by their very close and regular sori. 



62. A. Uneatum, Swartz ; st. tufted, G-9 in. 1,, firm, erect, more or less icaXj ; 

 fr. 1-2 ft. 1., 4-6 in. br., oblong-lanceolate, with 20-.30 ^^e?ma? on each side, which 

 are 3-4 in. 1., about \ in. br., acuminate at the point, dentate throughout, all 

 sessile or nearly so, the base cuneate, but the lower side narrower and 

 more cut away than the upper ; Uxture herbaceous ; colour dark-green ; 

 rachis brownish-grey, and slightly paleaceous ; veins close, often forked ; sori 

 very regular, reaching from the midrib nearly to the edge.— /ZX-. Sp. 3. p. 104. 



Hab. Mauritius and Bourbon. — A very puzzling plant, from the fact that it runs gra- 

 dually into forms with the pinnse again pinnate, which have either small narrow linear- 

 cuneate pinnules (Darea incequalis, Willd., and D. UMa, Kaulf.), or evea these latter 

 again deeply bifid or pinnatifid (Z>. hifida and violascens, Bory). 



63. A. prionurus, J. Sm. ; st. tufted, 6-9 in. 1., firm, erect, slightly scaly below ; 

 fr. 12-18 in. 1., 6-9 in. br., oblong, with 9-18 pinnce on each side, which are 4-6 

 in. 1., rather ovei' \ in. br., very much acuminated at the point, deejjly and 

 regularly toothed throughout, the base rather unequal, more truncato-cuneate 

 on the lower side, with a short distinct petiole on the lower ones ; texture her- 

 baceous ; veins usually simple, with sori on each reaching nearly to the edge.

Hab. Philippines, Cuming, 197. — Probably this should be united with A. Uneatum. 



64. A. lumdatum, Sw. ; st. tufted, 2-4 in. 1., firm, nearly naked, grey or 

 ebeneous ; /r. 6-18 in. 1., 1^-2 in. br., narrowly lanceolate-oblong, with 12-20 

 hoi-izontal pinnce on each side, which are 1-1 1 in. 1., \-^ in. br., bluntish or 

 acute at the point, more or less deeply inciso-crenate throughout, the two sides 

 unequal, the upper one at the base narrowed suddenly at about a right angle, 

 the lower one obliquely truncate ; lower pinna? often deflexed ; texture herbaceous ; 

 rachis firm, greyish ; veins simple or once forked ; sori falling short of both edge 

 and midrib. — A. erectum, Boiy. Hk. Sp. 3. p. 127. 



Hab. Universally distributed throughout the Tropica ; America, from Cuba to Rio 

 Janeiro and Juan Fernandez ; Sandwich Islands, Indian and Malayan Peninsula, Ceylon, 

 Cape Colony, Tristan d'Acunha northward to Bourbon, St. Helena, Ascension, and tlie 

 Guinea coast. — A. harpeodes, Kunze, Hk. Sp. Fil. t. 178, is a large form with acuminate 

 pinnse; A. Fernandeslmmm, Kunze, a form from Juan Fernandez, with a more rigid 

 rachis and subcoriaceous pinnse; A. tendlum, Eoxb. {A. reclinatum, Houlst., Hk. Fil. 

 Exot. t. 72), a form with wide-spreading, dark-green fronds copiously proliferous at the 

 apex ; A. Barteri, Hk. 2nd Cent. t. 75, a slender flaccid plant, also proliferous ; A. ptcr- 

 opus, Kaulf., and A. camptorachis, Kze., forms with the rachis compressed and slightly 

 winged ; and the pinna; are sometimes more or less distinctly pinnatifid, as in the 

 S. African A. lohatum and A. grac'de of Pappe and Rawson, and the Polynesian A. Ma- 

 crcei, Hk. & Gr. t. 217. Kunze and Mettenius consider this to be the A, lunulatum of 

 Swartz, which is an older name than erectum. 



65. A. persicifolinm, J. Sm. ; st. and rachis grey, with a few scattered minute 

 grey scales ; /r. ol)loiig-lanceolate, 2-3 ft. 1., olten gemmiparous at apex ; pinnce 

 distant, ascending, ].5-30-jugate, sul)j)etiolate, 4-5 in. 1., lineai'-ligulate-acuminate, 

 ^-| in. br., distinctly inciso-crenate throughout, more cuneate on the lower than 

 the u])per side at the base, the lowest not reduced ; texture thin but firm ; surfaces 

 dark-green, naked ; veins erecto-])atent, line, forked, not close ; so7-i regular, 

 jjarallel, 3-4 lin. 1., reaching nearly to midrib and edge. — Ilk. Sp. 8, p, 109,
