P. erosa belongs to a common type of Himalayan 

 Primulas, that of which P. denticulata is the prevalent 

 form, and P. capitata the rarer. In their usual states they 

 are distinguished as follows : P. denticulata by haying 

 sparingly mealy or glabrous finely toothed leaves, that are 

 not fully developed till after flowering, and which are 

 surrounded at their bases by fleshy, scales, formed by the 

 arrested outer leaves on the crown of the rootstock ; it 

 bears a large or small depressed globose head, the flowers 

 of which are lilac or purple, and all open together. Plate 

 395-9 of this work is an excellent representation of it, 

 showing well the fleshy arrested leaves on the crown of the 

 rootstock. The figure in the Botanical Register (1842, 

 t. 47) is also characteristic, though the arrested leaves are 

 concealed. 



P. erosa differs from denticulata in its much slenderer 

 habit, in always (except on young parts) wanting the meal 

 on the leaves, which are developed at flowering time, are 

 translucent with strongly erose and denticulate margins,
