94 THANSACTIONS AND PROCEEDINGS OF THE [Skss. lxvi. 



short glandular hairs ; involucral bracts about reaching 

 base of calyx : capsule halt' the length of calyx ; flowers 

 rosy, with whitish throat which is covered with longish 

 glandular hairs. 



These two last Primulas do not properly belong to the 

 group Arthritica, being destitute of cartilaginous border. 



C. The next group comprises six Primulas, and is named 

 by Schott Eky'J'hrodkosum. Its characters are — leaves 

 fatty, dentate-serrate or serrulate, without cartilaginous 

 border, densely covered with hairs, which exude a red gum, 

 veins immersed. Involucral bracts short, flowers peduncled, 

 red or white, not yellow, calyx longish. 



11. P. HiRSUTA, All., = p. viscosA, Vill. — Pyrenees and 

 Alps ; very widely distributed. Leaves obovate or rounded- 

 obovate, more or less toothed along the whole margin ; 

 capsule shorter than the calyx. 



Of this Primula there are four varieties — (1) P. ciliata, 

 Schrank, in which the teeth of the leaves are equal, and 

 the margin is white and densely glandulose ; (-) ^. imllida, 

 Schott, with unequal teeth, pale lilac blooms and cuneate, 

 obovate flower-tips ; (3) P. co7ifinis, Schott, with very fleshy, 

 extended leaves, thickly covered with brown glandular 

 hairs, broad corolla-tips, and very short calyx teeth ; (4) 

 P. excapo, Heg., with sessile leaves, whose teeth are 

 cut in the form of an arch, and with almost stemless 

 flowers, which sit on the rosette of leaves, and are together 

 almost larger than the whole plant. This Variety occurs 

 at very high altitudes. There is also a variety with white 

 flowers, which is the so-called P. nivalis of gardens. 



12. P. CENENSis, Thorn. — Found on the Alps of the 

 southern and western Tyrol, and of eastern Switzerland ; 

 Ortler, Val Muranza, Val Daone, Val Venosta, etc. This 

 is the smallest of the group, though other species may be 

 found as small, when they grow in poor, dry situations, or 

 at high altitudes. Its small, cuneate, and truncate leaves 

 are found among none of the allied Primulas ; but to make 

 sure of correct identification, it is well to note the character 

 of the hairs on the very viscid leaf, which are thick and 

 short and bear large reddish yellow or dark red glands, the 

 calyx pressed close to the corolla tube, the short peduncles,
