3. A. ascendens, n. s. 



A. ascendens, frondibus sterilibus glabris deltoideis bipinnatis longe sti- 

 pitatis, pinnis lanceolatis basi truncatis, pinnulis et laciniis lanceolatis ar- 

 gute serratis, laciniis inferioribus minoribus ; fertilibus bipinnatis, pinnis 

 superioribus pinnatifidis, inferioribus pinnatis, pinnulis rotundatis sinuatis, 

 soris solitariis, caudice scandente dense paleaceo. 



Caudex scandens digitalis crassitudine. Paleae acerosae fuscse. Stipes 

 pedales scabriusculi. Frons sterilis 8-10 pollicaris glabra. Pinnae 3 pol- 

 licares suboppositae. Pinnulae pollicares. Laciniae lanceolatae argute ser- 

 ratae inferioribus minutis. Frons fertilis 5 pollicaris. Pinnae pollicares al- 

 ternae. Indusium peltatum glabrum. 



This is a very remarkable species of Aspidium, and totally distinct 

 from any that I have ever seen : it is very common in the mountain fo- 

 rests round Old England plantation, Manchester, climbing 20 or 30 

 feet up the trunks of trees. I found the fertile fronds but twice ; they 

 are very remarkable, being so different in form to the sterile ones. — 

 There is a figure in Raddi of a sterile frond, (A. scandens, t. 49), that 

 appears to be nearly allied to this species, hut the form of the pinnulae 

 is different, and they are on longer footstalks. Raddi had not seen a 

 fertile frond. 



** Indusium reniforme, (Nephrodium, Mich.)

Very frequent in the woods in the Mayday Mountains, almost in- 

 variably growing on prostrate decaying trees, for their whole length.
