1862.] AND ITS VARIETIES. 241 



parts small and finely toothed^ and the whole so remarkably con- 

 vex that the fronds cannot be flattened. A form very like this 

 has been found near Aberdeen. 



Finally, in this series comes a Lowland Scotch plant which Ave 

 call LATA, a broad form with large pinnules, not like the large 

 broad ordinary plants common in England, but having a pecu- 

 liar leafy character from the coarse lobes of the pinnules being 

 broadly confluent. 



Then of the oblong-fronded series we have stricta, a Somer- 

 set plant, with a narrow lamina of eight or nine inches to the 

 upright-growing fronds, and the pinnae all directed upwards at 

 an angle of about forty-five degrees ; it is a very unusual-looking 

 dilatata. 



Another is RTicuRViFOLiA, from Aberdeen and Moffat, the 

 latter rather the broader of the two, both comparatively dwarf 

 plants, and remarkable for having rather crowded sessile pinnules, 

 very decidedly convex on their upper surface, the fronds having 

 at the same time a tendency to concavity along the centre of the 

 pinnae. 



A third neat and very elegant form, received from the West 

 of Scotland, which we call adnata, though small, the lamina 

 being less than a foot long, is to the eye a much divided variety, 

 from its evenly and deeply-cut character. It is rather slender ; 

 and the pinnules are sessile, and of a nearly regular oblong-ovate 

 acute form, cut nearly to the midrib, and to about the same ex- 

 tent all the way up, into small even-sized acutely-toothed lobes, 

 so that the midril) of the pinnules appears to have a narrowish 

 equal wing throughout its length, with which the lobes are adnate. 



Larger forms of the oblong-fronded series occur in the variety 

 ALTA, au Aberdeen plant of erect robust habit, four or five feet 

 high. This is distinctly tripinnate, with the pinnules averaging 

 an inch, the larger ones two inches long, the lobes rather distant, 

 oblong, a quarter of an inch long and strongly toothed at the 

 tips, almost entire towards the base where they are more or less 

 confluent. The prominent apical toothing somewhat resembles 

 that of grandidens. It is, we understand, a well-marked and 

 abundant wild plant. 



Another very beautiful Scottish plant, but from the west coast, 

 we propose to call ORDEAXiE, though of its position in this group 

 we are not quite certain, having only seen portions of its fronds.
