above, with a little obtuse elbow, termi- 

 nating in a minute spine outside at their 

 base, running level with the stem of the 

 pinna; sloping down into a stalk-like 

 junction with that stem, apex directed 

 upwards ; the largest and nearest the main 

 stem parallel with it, and leaving an inter- 

 mediate line of light ; much and very deli- 

 cately toothed throughout, with thin, short 

 hair-like, bristles ; rounded altogether to 

 the eye, and without sharpness or angu- 

 larity. Sometimes, however, more acute, 

 coarser in form, and approaching to Loba- 

 tum. Sori very small, and chiefly on the 

 higher pinnae. Under surface woolly. May. 

 Indeciduous. Not common. Lancashire. 

 Devonshire. Easy of cultivation. Very 

 elegant and graceful.

 Fern.} Fig. 14. From 2 to 3 feet. Growing

 and often falling back at their ends. Pin- 

 nules finely and slenderly stalked, flat, 

 oblong, broadish, rather thin and soft, or 

 entirely so, repeatedly, deeply, and obtusely 

 toothed, or even divided, throughout, and 

 rounded upwards to a bluntish point.
