Rootstock none. Stem paniculately branched or simple. 

 Radical leaves in a rosette, oval-obovate ; stem-leaves oval, usu- 

 ally very shortly connate at the base ; all sub-acute, 3-ncrvcd or 

 indistinctly 5-nerved, flat. Flowers solitary, terminal and axil- 

 lary, stalked, with 2 elliptical bracts a little way below the base 

 of the calyx, arranged in a raceme or racemose panicle which is 

 sometimes reduced to a single terminal flower. Calyx-tube cylin- 

 drical, indistinctly 5-angled ; segments 5, triangular-strapshapcd, 

 rather shorter than the tube. Corolla-tube about one-third longer 

 than the calyx, cylindrical, without hairs in the throat ; limb of 

 5 roundish-oval obtuse lobes, about one-fifth the length of the 

 tube, not ciliated. Capsule sessile or sub-sessile. 



On grassy places in mountainous districts. Rare. Between 

 Craig Chailleach and Ben Lawers, Breadalbane, Perthshire ; and in
