Hab. Islaud of St. Thomas, W. Africa, G. Mann. — Very near N. SpeJcei, but smaller 

 in size, the veinlets fewer, and the rachises densely fibriUose and glandular, and sori 

 Bubmarginal. 



26. N. (Last.) ligulatum, Hk. ; 5^. gre}^, glossy, naked ; fr. 3-4 ft. 1., 12-18 in. 

 br. ; /%>(M« 6-9 in. 1., 1 in. br., cut down very nearly to the racliis into linear, 

 blunt, entire, erecto-patent lobes 1 lin. br., with more than their own space 

 between them, lower ones slightly reduced ; texture subcoriaceous ; rachis and 

 under side finely pubescent ; veinlets 10-12 on a side; sori quite marginal. — 

 Hk. Sp. 4. jo. 112. 



Hab. Philippines, Cuming, 94, 343. — Allied to the three preceding. 



27. N. (Last.) olliquatum. Baker ; rhizome creeping ; st. 8 in. 1., reddishj 

 densely pubescent ; fr. 1 ft. 1., 6-8 in. br., ovate-acuminate ; pinnce lanceolate, 

 cut down to a narrowly-winged rachis into close linear-oblong entire lobes ; 

 textivre pa])yraceo-herbaceous ; under surface and rachis densely villose ; veinlets 

 6-8 on a side, bearing the sori near the apex. — Aspid. Mett. Fil. Nov. Cal. p. 76. 



Hab. New Caledonia, Vieillard, 1628. — Allied to species 23-27, but recognizable by 

 its villose stems and frond. 



28. N. (Last.) albo-punctattcm, Desv. ; rhizome wide-creeping, scandent, scaly 

 or naked; st. naked, greyish or ebeneous, jointed ; fr. 9-12 in. 1., 4-6 in. br. ; 

 pinnce spreading, 2-3 in. 1., \ in. br., cut half down to the rachis or more into 

 oblong, blunt, entire lobes ; texture herbaceous ; rachis pubescent and under side 

 slightly so ; veins pinnate in the lobes, with 8-4 veinlets on each side ; sori 

 terminal on the veinlets near the edge. — Hk. Sp. 4. p. 85. Fil. Ex. t. 89. 

 Arthropteris, J. Sm. 



Hab. Guinea, Natal, Angola, Mascaren Isles, Fiji. — The pinnse have white cretaceous 

 dots on the upper surface, as in Nephrolepis. N. Webbianum, Hk., from Amboyna, 

 appears to be a form of this, with n, glabrous rachis and pinnae less deeply lobed than tlie 

 type.

 above; st. 1 ft. 1., 8-6 in. \>^.\ ^;i2J?»?«? spreading, 2-4 in. 1., |-| in. br., cut

 p. 108. 



Hab. N. India to Ceylon, Hong-Kong, Philippines, Malaccas. — A well-marked plant, 

 with a considerable range of variation in cutting and texture. The lower pinnae are 

 sometimes but not usually reduced. N. falcilobum is a form with broader pinnae and 

 deeper and more spreading lobes than usual.

 slightly scaly, finely villose ; //'. 9-12 in. 1., 4-5 in. br., oblong-lanceolate ;
