Stipatum, Wollaston. — A dense-pinuuled form of Detiswn, 

 (Moore.) Found by Mr. A. Tait. Quite lanceolate, tapering 

 both below and above, pinnjB brief and overlapping each other, 

 pinnules ovate, acute, auricled and serrate on their margins, 

 decurrent except the basal one, which is briefly stalked. The 

 pinnules are crowded together so as to overlap each other. Mr. 

 G. B. AVoUaston informs me that the plant is nearly dead.

Gractle, Wollaston. (Fig. 71.) — Found in Devonshire by 

 Mr. Wollaston. A most graceful, much cut, distinct variety, 

 more nearly resembling Lineare than any other form, yet 

 being sufficiently distinct from that variety. The fronds are 

 bipinnate, the form being ovate, attenuate at the apex. The 

 habit lax. Pinnules small, narrow, oblong-acute, and distinct, 

 scarcely auricled, the margin inciso-serrate, irregular in form, 

 many linear with a cuneate base. Those on the upper pinnae 

 are very acute, and bear on each three or four distinct sori. 

 The entire upper pinnae and the apices of the basal ones are 

 confluent and lobate-serrate. The apex of the frond is lengthened 

 and slender, becoming caudate. Base of frond very scaly. My 

 thanks are due to Mr. G. B. Wollaston, of Chiselhurst, for fronds. 



A variety of this form under the name of Gracile, (Xo. 2.) 

 has been sent to me by Messrs. Stansfield, of Todmorden. 



Athtrioides, Wollaston.— Found, at Barnstaple by Mr. C.
