This plant has very patent leaves, as its name implies ; more- 

 over, these are strongly serrated, and their nerve disappears 

 before reaching the point, circumstances which will alone suffice 

 to keep it distinct from P. cuspidatum. A slight variety, the 

 leaves being somewhat narrower, is the P. recurvifolium of 

 Dicks, and Nees et Hornsch. ; the P. pachycarpon, Schwaegr. 



7. P. muticum ; leaves broadly ovate concave acuminate more 



or less serrated connivent, the nerve reaching to the point. 

 . Leaves sharply serrated at their points.

This is a species admirably distinguished by its concave and 

 closely connivent leaves, which give the whole plant the appear- 

 ance of a little bulb. We have found an extremely small 

 variety of it at Torquay in Devonshire, which we have distin- 

 guished as above, as our var. j8. and which approaches so nearly 

 to the P. Florkeanum of Schwaegrichen, and the P. badium of 

 Nees et Hornsclmch, that we can really find no other difference, 

 except that the leaves of these latter are somewhat patent, so 

 as to allow the fruit to be visible in a state of growth, whilst in 

 our plant they are as connivent as in a. In the more common 

 state of the species the serratures at the extremities of the 

 leaves are subject to considerable variation; and even when 

 quite entire, the plant may be known from P. cuspidatum by 

 its much more convex leaves, and by their more rigid texture 

 as well as more glossy surface. 



8. P. cuspidatum ; leaves ovate-acuminate erect entire, the nerve 



reaching to or beyond the point. (TAB. V.)
