 also ap|)ears to be to Mettenius. 



375. P. (Phymatodes) dilatatuin,\Na\\.', caudex creeping 

 (short?) paleaceous with ovate reticulated scales, stipites \h 

 foot and more loni^ but strongly winged for its whole length 

 by the decurrent base of the frond (not articulated on the 

 caudex), fronds ample 1^-2 and 3 feet long a foot and more 

 wide membranaceous light-green glalirous oblongo-ovate pin- 

 natifid to within ^-1 inch of the racliis (less towards the base), 

 segments 5-6 or 8 inches long (shorter towards the apex) jf-l 

 rarely 2 inches wide oblongo-lanceolatc acuminate entire sud- 

 denly decurrent, costules veniform forming large primary 

 areoles which extend two-thirds of the way to the margin and 

 include the sori, these and the rest of the segments are occu- 

 pied by lesser irregular areoles including many free veinlets 

 their branches moderately divaricating, sori numerous very 

 small often oval or more or less elongated compital on the 

 secondary veins and veinlets. — IVull. Cat. n. 295. Drynaria

 has heeu largely distributed by Dr. Wallich forty years ago ; but has not, as far 

 as I can discover, been noticed by any one, unless it be the Drynaria acuminata, 

 L5rack., who does not, however, notice the most remarkal)ly winged stipes. There 

 is no joint at the junction of the latter with the caudex, and the breadth of the 

 united wings on the stipes is very considerable, and, no doubt, suggested the Wal- 

 lichian name of dilatatum. 



376. P. (Phymatodes) alaiuin, Hook.; caudex elongated 

 creeping rather stout and woody destitute of scales in my 

 specimen, stipites 2-3 feet long pale stramineous as well as 

 the rachis, fronds I5-2 feet long 10-12 inches wide broad- 

 oblong membranaceous glabrous deeply pinnatifid with ob- 

 tuse sinuses sul^piimate below, segments patent 6-8 inches 

 l-ong 1-1} inch wide (in my specimen opposite or very nearly 

 so) from a somewhat contracted but decurrent base lanceo- 

 late obtuse or acuminate sinuato-dentate, venation manifest, 

 costides slightly prominent slender extending to the margin 

 united by rather irregular flexuose transverse veins (all pel- 

 lucid in my specimens) into 3-4 series of soriferous areoles, 

 these are again occu])ied by irregular smaller areoles inclu- 

 ding free veinlets, sori small appearing at first sight irregularly
