90 POLYPODIUM, § PHYMATODE8. 



pinnated state of P. palmatum, and certainly that of Mettenius, who gives " Sin- 

 gapore, Walker" for the authority, whence I received my pinnated specimens, 

 but which were accompanied by fronds of the ordinary form. P. Lindleyanum, 

 Wall., is identical with this. 



**** Fronds pinnated. Sp. 384-390. 



384. P. (Phymatodes) capitellatum, Wall. ; caudex very- 

 stout creeping clothed with ovate or lanceolate rather large 

 ferruginous acuminated appressed scales, stipites 1 foot and 

 more long brown glossy as well as the rachis, fronds H-2 

 feet and more long coriaceo-submembranaceous, pinnae 15-21 

 in remote pairs sessile except the terminal one (which is long 

 petiolate) 5-6 inches long 1-2 inches broad from a rounded 

 base oblong-lanceolate finely acuminated entire or slightly 

 sinuato-lobate at the incrassated margin, venation in general 

 manifest, costules very evident straight extending to the 

 margin, these are connected by transverse veins with 3-4 

 series of areoles again divided into lesser areoles including 

 free divaricating veinlets, sori large compital superficial (not 

 sunk) arranged in a single series nearer the costa than the 

 margin.— fr«//. Cut. n. 306. Metten. Pohjp. p. 109. Phy-

Hab. Himalaya, Kepal, Kumaon (7000 feet), and Srinuggur, JJ'allich ; Simla, 

 Ladi/ DalhousJp, Col. Bates; Khasya, Griffith, Simons, Hooker fit. and Thomson 

 (alt." 4000 feet) ; Sikkim, Hooker fil. and Thomson (7000-10,000 feet) ; Boutan, 

 Griffith. — In the venation, in the opposite pinme articulated upon the rachis, this 

 has consideral)le affinity with P. Bimalayense, but the single series of large sori, 

 the slender thickened opaque margin (not broad and diaphanous) and broad 

 scales of the caudex would seem to keep it abundantly distinct. Nevertheless I 

 fear we have much to learn on the subject of variation in every part of Fern 

 structure. Among my numerous specimens of these two I find a state with al- 

 ternate pinnae. P. Himalayense has not always broad diaphanous margins; P. 

 capitellatum varies with two series of sori between the costa and the margin, 

 and the scales of the rachis vary much in width even on the same caudex. 

 It is more than likely that the two will constitute one species. One form of 

 this in my herbarium has the pinnae all very deeply laciniated ; but this is evi- 

 dently a lusus nature. 



385. P. (Phymatodes) tenuicauda, Hook.; caudex stout 

 creeping clothed with rather large lanceolate acuminate fer- 

 ruginous scales, stipites a span to a foot long, fronds 1-1 1 foot 

 long coriaceo-membranaceous ovato-oblong pinnated, pinnae 

 subopposite and alternate distant articulated upon the rachis 

 all more or less petiolate 6-8 inches long ^-1 inch wide 

 elongato-lanceolate obliquely cuneate at the base tapering 

 above into a long and very finely almost setaceously acumi- 

 nated apex entire and very slightly thickened at the margin.
