 pinnatifid, stipes scaleless). — It is very doubtful whether this should be consi- 

 dered a Diplazium or an A thyrium. 



236. A. (Atliyrium) thehjpteroides, Mich.; caudex stout 

 creeping, stipites rather distant on the caudex a foot or 

 more long stramineous glossy brown below, fronds 1-3 feet 

 long submembranaceous dark green lanceolate-acuminate 

 firm pinnate, pinna) subremote horizontal 3-4 inches long 

 sessile from a broad base linear-oblong acuminated deeply 

 almost to the rachis pinnatifid, segments oblong-elliptical ^ of 

 an inch long horizontal entire or obscurely serrated very ob- 

 tuse, veins mostly simple-pinnated, sori linear-oblong in two 

 series approximate upon the segments soon confluent, invo- 

 lucres convex pale firm-membranaceous entire convex at the 

 margin straight, rachis stramineous. — Mich. Fl. Bar. Am. ii.

 Sikkiin-Himalaya, elev. 9-10,000 feet, Jlook. fil. et Thomson. River Amur, 

 Chinese Tartary, Maximou-icz. — A very distinct and handsome species. North 

 Indian specimens are clearly identical with the North American form.

 line wide glossy, frond H-2 feet long ovato-lanceolate mem- 

 branaceous bi-tripinnate, primary pinnce long-petiolate re- 

 mote erecto-patent a foot and more long broad-lanceolate acu- 

 minate, secondary pinnrc 5-6 inches long lanceolate nearly 

 sessile pinnated, pinnules numerous approximate oblong- 

 lanceolate much acuminate horizontally patent 1-1 4 inch 

 long coarsely serrated rarely sul^pinnatifid the serratures very 

 acute almost mucronate lowest pinnules more distant on 

 short pctiolules intermediate ones more approximate the 

 lower base decurrent, upper ones confluent, veins pinnated, 

 veinlets forked once or more, sori generally in two rows 

 oblique near the costule in the pinnules that are pinnatifid
