E/Ootstock 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-nerved or 

 indistinctly 5-nerved, flat. Plowers 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-strapshaped, 

 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 

 Canlochan Glen, Eorfarshire. I have gathered it only on the east 

 slope of Catjaghiamen, a little to the east of Craig Chailleach.

 leaves lanceolate or triangular-lanceolate, not connate, acute ; all 

 3- to 7-nerved, flat. Plowers terminal and axillary, stalked, with- 

 out bracts near the base of the calyx-tube, arranged in a slender 

 panicle, which is reduced in small specimens to a raceme. Calyx- 

 tube obconical ; segments 5, slightly unequal, triangular or lan- 

 ceolate-triangular, acute, rather longer than the tube. Corolla- 

 tube longer than the calyx, fringed with hairs at the throat ; limb
