out outside, tube cylindric expanded above stamens, in long- 

 styled flower about 1 cm. long, in short-styled about 1'4 cm. 

 long, about twice the length of calyx, white tinted yellow 

 at top, glabrous inside, exannulate with a circular mouth ; 

 disk of the flat spreading limb about 1'5 mm. broad yellow- 

 green glandular-puberulous somewhat strumous at base; 

 lobes 5 obcordate 1 cm. long and broad or more, deeply 

 emarginate minutely papillose above. Stamens in long- 

 styled flower inserted near base of corolla-tube about 

 equalling calyx in short-styled above middle of corolla- 

 tube with anther-apices about 35 mm. from its mouth, 

 anthers almost sessile narrow about 2 mm. long. Ovary 

 green nearly globose ; style white, long style included in 

 corolla-tube a little longer than calyx, short style scarcely 

 as long as calyx, twice length of ovary ; stigma pale 

 green capitate. 



Szechwan. " Primula rupestris occurs on hard dry 

 reddish limestone clifl's in the Da Ba San (Ta Pa Shan), 

 seen flrst between Ming Chiang Chow and Tai-an-i, down 

 over the Sliensi-Szechwan border, and last seen on a lime- 

 stone blufl" above the Kia Ling Kiang where it debouches 

 into the Red Basin of Szechwan. The journey between 

 Lo-yang and Kwang-Ylien goes each day over a low little 

 wooded range running up to some 8000 ft. The Primula 

 haunts clifl- faces in tlie gorges, exactly as P. Allionii grows 

 in the dry luud clifl-faces of the Roja. Only withered 

 relics were to be seen when I passed through in early 

 November 1915; in fact it was only with much difliculty 

 and after long search that I succeeded in finding a few 

 seeds still lingering. In such conditions it is hardly to be 

 wondered at if I failed to ditturentiate it from P. sinensis, 

 remote though such an extension of distribution would 

 have been. I have no doubt that P. rupestris pervades 

 all those small low ranges of the Da Ba San on its lime- 

 stone outcrops, on the gorge-clifls, etc., at an elevation of 

 some 6000-7000 ft. Its habits and habitat suggest a great 

 dislike for winter damp, but from its geographical station 

 I hoped it might prove as much hardier than P. sinensis 

 as has since been proved to be the case." — R. Farrer. 



From seed collected by Mr. Farrer, P. rupestris is now in 

 '•ultivation and flowered in 1016 in the Royal Botanie
