100 TKANSACTIONS AND l'ROCKP:iJ[N(;S OF THK [Sess. Lxvi. 



Leaves stiitish, shining, without cartih^ginous border, 

 cuneate or obtriangular, apex truncate, more rarely arcuate, 

 funiished with three to nine acuminate-mucronate teetli, 

 glabrous, the margin of the leaves and the superior green 

 parts of the plant sprinkled with minute glandular hairs. 

 Flower-stalk short, rarely as long as the leaves, one to two 

 flowered. Peduncles almost none, or as long as 3 mm. 

 Involucral bracts lanceolate, generally a little shorter than 

 the calyx, the apex acuminate or somewhat mucronate. 

 Calyx green, 6 to 9 mm. long, with mucronate teeth. 

 Flowers rosy; throat and interior of corolla-tube glandular- 

 villous, white. Limb of the corolla broad, plane behind, 

 clearly distinct from the tube: its radius 7-16 mm. long. 

 Lobes of the corolla obcordate, bifid, cut from two-fifths to 

 half its length. Anthers of the short-styled flowers 

 generally set on the middle of the tube. Capsule hardly 

 reaching half way up the calyx. 



Widmer's description is here given in full, as this 

 Primula is often difficult to distinguish from some of its 

 hybrids. With regard to the teeth at the apex of the 

 leaves, he remarks that, after a careful examination of a 

 great number of plants from diffierent districts, the follow- 

 ing four groups can be made out : — 



In No. 1 all the teeth are of the same size and height. 

 In No. 2 the two, three, or four middle teeth are equal 

 in size and height, while those at the sides are not so high, 

 and §ire often also smaller. 



In No. 3 all the teeth are pretty much of one size, but 

 are set on an arched line, so that the middle one is some- 

 what higher than the others. 



In No. 4 all the teeth form. an arched line, the middle 

 one is the largest and highest, while the rest decrease in 

 size on both sides of it, so that the outermost ones may be 

 much smaller than the central one. 



22. P. DEOiiUM, Vel. — On Mount Kilo, in Bulgaria, in 

 moist, grassy spots beneath .the snowfields, at an elevation 

 of 8000 feet. On syenite. 



Leaves slightly fieshy, rather coriaceous, stiff", with a 

 distinct cartilaginous border, punctate on the upper side 

 (the points, not translucent, dark in reflected light, being 

 little shallow pits) ; oblong or lanceolate, with acute apex ;
