Most of the specimens collected are distinguished by having the under sides of the 

 leaves considerably more densely tomentose than the upper sides, which, accordingly, 

 are of a more greenish colour. The spike is solitary, rather loosely flowered below, 

 with comparatively long bracts; the flowers are closer above, and with shorter bracts, 

 equalling or shorter than the calyx. 



Besides this one, I have collected, near Tagarsld osero, some specimens of a form 

 distinguished by being densely tomentose all over the plant, so that it has the appearance 

 of being nearly snow-white. The upper sides of the leaves are as densely hairj- as the 

 under sides. These specimens are also distinguished by ha\ing the bracts comparatively 

 longer, always exceeding tlie calyx, the lower ones sometimes rather much so. The struc- 

 ture of the flowers, for the rest, agrees perfectly in both forms. The corolla is in both 

 of them of one blue colour when dried; it appears, however, from the boiling out of the 

 flowers — which I have undertaken for the pui-pose of examining their structure — that 

 the corolla assumes a light blue ground colour, with small, regular, roundish-ovate spots 

 of a deeper blue. 



This species is scattered over the territory traversed, on dry liills and in dry mea- 

 dows, frequently in sandy places, on rocks, etc. Near Ust .\bakansk, at Askys, and also 

 at Tagarski osero I have collected it with young. paiUy opened flowers at the end of 

 June and the beginning of July. In the Urjankai country I have met with the species 

 rather frequently in the steppe and wooded steppe regions, viz. in drj% sandy woods of 

 larch and pine at Ust Sisti-kem, at Ust Kamsara, and near Bjelosarsk, past flowering at 

 the end of August. 



Distribution: South-eastern Europe, Caucasia, and adjacent portions of Asia, south- 

 ern Siberia, except the more eastern parts.
