Garden, Edinburgh. It is a near ally of the well-known 

 P. sinensis, Lindl. of Western Hupeh and Eastern Yunnan, 

 the only species hitherto described of the Auganthus series 

 of Primula. Hardier than its ally, it may prove a valuable 

 addition to the plants of the outdoor garden, especially if 

 it varies as much as P. sinensis under cultivation. It 

 differs from the wild plants of P. sinensis in its larger 

 leaves with longer and stouter petioles, its longer and 

 stouter pedicels, the calyx abruptly tapering from the 

 .swollen base into the elongated triangular adpressed lobes 

 more than half the length of the calyx, the smaller corolla 

 limb. As in P. sinensis the corolla is glandular on the 

 outside. I mention this because Pax says the corolla in 

 P. sinensis is eglandular. 



At the Primula Conference in 1913 I referred to the 

 geographical distribution and the variability of the Chinese 

 species P. sinensis and P. obconica, Hance, pointing out that 

 whilst the latter is widely spread in Western China and 

 shows many form-modifications in relation to habitat in 

 cultivation, it has not varied or developed to the extent 

 exhibited by P. sinensis, which is only known from the one 

 area about Ichang. Here we have now in this Szechwan 

 plant a form-modification of the tj^pe of P. sinensis, and 

 it may be taken as indicating that there are probably others 

 to be discovered in the wide region that intervenes between 

 W. Hupeh and Kansu. There is another form in cultiva- 

 tion, found by Wilson in W. Szechwan (I believe), but no 

 description of it has yet appeared — a fate that has attended 

 so far many interesting new forms of Primula collected by 

 Wilson, dried specimens of which have been distributed by 

 the Arnold Arboretum.
