serrato-acuminate point, 1-3 lowest pair more or less (often little) re- 

 duced and deflexed, pinnatifid f ths. or 4-5ths. to the costae ; seg- 

 ments close, oblong, often subfalcate, flat and bluntish, J in. 1. from 

 the acute sinus, li. b., basal pair largest ; margins even or subcrenu- 

 late ; rachis stramineous, grayish-pubescent ; v eins simple, 7-9 to a side, 

 the lowest pairs forming narrow arched areolae and sending a distinct 

 branch to the sinus, above which the next pair terminate ; sori medial ; 

 involucres as large, pale, pubescent SI. t. 50, fig. 2. Herb. Aspi- 

 dium, Swartz. 



Common in open and half over- grown places up to 3,000 ft. altitude, 

 or higher, and generally diffused throughout the island. As in stipu- 

 lare the basal pinnules of the lower pinnae are often enlarged and pinna- 

 tifid. I have under those species pointed out that from stipulare this is 

 distinguished by the lowest veins sending a simple branch to the sinus 

 from their anastomosis, (not running together thereto), and from pa- 

 tens its other ally, by the same character, and the erect rootstock. The 

 texture of this is perhaps softest of the group. 



45. N. guadalupense, Fee. — Stipites numerous, caespitose from a 

 stout, upright rootstock 15-21 in. 1 , not, or faintly, channelled, gray- 

 ish- puberulous, and sparsely deciduously scaly at the base ; fronds 

 spreading, ovate-lanceolate, the acuminate apex pinnatifid, 2-3 ft. 1. 

 10-15 in. w., thinly chartaceous, pellucid, grayish-green, especially be- 

 neath, and clothed with minute scattered stellate puberulae, as are 'the 

 rachis and ribs also ; pinnae numerous, spreading, 1-1^ in. apart, 6-8 

 in. 1„ f -1 in. b., upper ones truncate and broadest at the base, lower 

 shortly narrowed there and more distinctly stipitate, lowest pair not, or 

 little, reduced, and deflexed or horizontal ; cut J-f rds. to the costae in- 

 to flat obliquely rounded subfalcate entire segments, 2 li. b. and 3 li. d. 

 to the narrow sinus, passing gradually outwards into the finely acumi- 

 nate subentire point ; veins simple, 10-12 to a side, 1-3 lowest pairs 

 uniting at, or the inferior pair running together to the sinus ; sori me- 

 dial ; involucres small, pale, puberulous. — Fee. Fil. Ant. t. 24. fig. 3. 



Common in forests and shady waysides from 1,500-4,000 ft. altitude. 

 The terminal pinna is hardly distinct, though in cutting it more or 

 less resembles the lateral but is generally broader, the upper pinnae 

 being gradually reduced till they pass into it. Marked by its gray 

 stellate puberulous vestiture, which is very dense on the rachis, costae 

 and ribs, broad lobed pinnae, the lower ones of which are narrowed cu- 

 neate-form at the base. The fronds are broadest in the lowest third or 

 half, from whence they narrow gradually to the apex. The rachis 

 relatively, slender.
