38 POLYPODIUM, § CAMPYLONEURON. 



§ 8. Campyloneuron. — Primary veins or costules pinnate, parallel, connected 

 by curvpd or angled transverse veins, forming areoles that include 2 or tnore 



free soriferous veinlets ,■ sometimes a central veinlet is prolonged and unites 

 with the transverse vein above. Fronds simple, often large, in one instance 



pinnate. — Gen. Campy loneurum, Pr. and others. Cyrtophlebium, Br. J. Sm. 

 Sp. 291-297. 



291. P. (Campyloneuron) Phyllitldis, Linn.; caudex short 

 stout creeping very much underground partially paleaceous 

 at length glabrous, stipites aggregated short, generally in ma- 

 ture specimens stout but variable often none, fronds 1-2-3 

 feet long 1-3 inches and more wide coriaceous rigid glabrous 

 generally glossy on both sides often with cretaceous dots 

 above opaque or submembranaceous elongato-lanceolate or 

 lato- or subobovato-lanceolate gradually or suddenly acumi- 

 nated rarely obtuse much attenuated and decurrent at the 

 base often down to the caudex, the margin entire or subsinu- 

 ose slightly thickened at the very edge, areoles 6-12-14 (va- 

 rying with the breadth of the frond) divided transversely into 

 two by a veinlet each one bearing a sorus. — Var. a, Linnce- 

 ana ; fronds elongato-lanceolate 1-3 inches wide. Plum.FU.

Hab. Tropical America, chiefly, I believe, confined to the Atlantic side and 

 the Caribl)ean seas ; from Porto AleE;re, in South Brazil, to Jamaica, in the north, 

 particularly abundant in the West Indian islands. — Var. ,3 inhabits the same re-

 some Fern, but which has given rise to great confusion in consequence of the exag- 

 gerated figures of Plumier. His representations of P. Phyllitidis (t. 130 and 131), 

 the original authority for that species, are tolerably satisfactory ; but his figure 

 of P. repens, for which species he is also authority, is so exaggerated and so 

 clumsy that not a few botanists have confounded the tAvo, and Mettenius, as may
