radicles the summit moderately clothed with lanceolate 

 sphagnoid scales, stipites tufted 6-12 inches long often com- 

 pressed pale, fronds 1-2 feet long ovate or oblong-lanceo- 

 late impari-pinnate submenibranaceous often thicker and sub- 

 carnoso-coriaccous, at the apex generally having a prolife- 

 rous gemma, pinna? 4-6 inches lojig oblong-lanceolate gene- 

 rally much acuminate the margin subincrassate usually entire 

 sometimes more or less serrated pctiolate the base unequally 

 cuneate the upper base rounded, terminal one generally large 

 long-petioled, veins conspicuous distant, sori copious but 

 distant oblique sometimes slightly falcated linear-oblong 

 commencing close to the costa never approaching the mar- 

 gin, involucres pale firni-membranaceous, rachis more or less 

 compressed and subulate above. — Schrad. GUtt. Gel. Anz.

 segments oblong or generally cuneate emarginate or bifid, 

 sori never at the margin but on the disc next the racliis : — a 

 subvariety of this is sent by Messrs. Pappe and Rawson, 

 with the base of the lower pinnce pinnate, superior ones 

 slightly lobed, the lobes emarginate, terminal pinnatifid, 

 pinnate in its lower half. — A. lucidum pinnatifidum, /SW//ecA/.

 Dalgains. Bourbon, Carmichael, in Herb. Nostr. ; this, hke Pappe and Ilawson's 

 specimen above noticed, exhibits two forms — one the ordinary state of this va- 

 riety; the other is copiously bipinnate, the pinna) less obtuse or retiise. Oahu, 

 in tbe Sandwich Islands, Beechey : the segments longer and deeper, sori very 

 frequently marginal (dareoid). — I had been formerly disposed to unite this, as 

 Schlechtendal had done, with A. lucidum, to which indcctl it is very closely allied ; 

 and it is subject to tbe same variations. But tbe caudox, wbcrever that is pre- 

 sent, never forms so thick and erect a rhizome, its scales are much less copious, 

 less mcml)ranaceous and glossy, the pinnae arc generally more membranaceous, 

 and tbe veins and sori more distant but more ap|)roximate to the margin. The 

 two states are well represented by Schlechtendal. In this and its allies the 

 stipes and rachis are more or less deciduously cbaffy. Schlechtendal refers tbe 

 A-ipl. virens of Presl, from Guayaquil, here, which we preserve as distinct.
