264: 44. NEPHRODIUM, LASTREA. 



It) 



Hab. Island of St. Thomas, W. Africa, Q. Mann. Very near N. Spekei, but smaller 

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

 subraarginal. 



26. N. (Last.) ligulatum, Hk. ; st. grey, glossy, naked ; fr. 3-4 ft. 1., 12-18 in. 

 br. ; pinnce 6-9 in. 1., 1 in. br., cut down very nearly to the rachis 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. p. 112. 



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



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

 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 ; 

 texture papyraceo-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, Vidllard, 1628. Allied to species 23-27, but recognizable by 

 its villose stems and frond. 



28. N. (Last.) albo-punctatum, 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 3-4 veinlets on each side ; sori 

 terminal on the veinlets near the edge. Hk. Sp. 4. p. 85. Fil. Ex. t. 8i). 

 Arthropteris, J. Stn. 



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

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

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

 type. 



29. N. (Last.) calcaratum, Hk. ; st. densely tufted, stramineous, villose 

 above; st. 1 ft. 1., 3-6 in. bi.; pinnce spreading, 2-4 in. 1., -| in. br., cut 

 down two-thirds or more to the rachis into oblique, subfalcate, linear-oblong, 

 acute or blunt lobes ; colour dark-green ; rachis villose ; texture herbaceous or 

 subcoriaceous ; under side more or less villose ; veinlets 3-6 on t each side ; sori 

 medial ; invol. glabrous, persistent. Hk. Sp. 4. p. 93. N. falcilobum, Hk. Sp. 4. 

 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. 



30. N. (Last.) viscosum, Baker ; st. 6 in. or more 1., firm, erect, reddish- brown, 

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

 pinnce close, 2-3 in. 1., - in. br., cut nearly to the rachis into close, spreading 

 linear-oblong lobes under 1 lin. br. ; texture herbaceous ; colour dark-green ; 

 rachises villose ; under surface densely glandular ; veinlets 5-6 on a side ; sori 

 medial. Lastrea, J. Sm. 



Hab. Malacca, Cuming, 401 ; Philippines and Borneo, T. Lobb. 



31. N. (Last.) falciculatum, Desv. ; st. tufted, 6-12 in. 1., clothed below with 

 dark-brown linear scales; fr. 12-18 in. 1., 8-10 in. br., oblong-deltoid ; pinnce 

 4-5 in. 1., 1 in. br., cut down very nearly to the rachis into linear-oblong entire 

 falcate lobes 1^-2 lin. br., the lower ones not reduced ; texture herbaceous ;
