When we had crossed this plateau, and came to grass, we found a gorgeous carpet of the huge couched blue gentian (_G. _Gentiane sans tige_), with smaller patterns put in by the dazzling blue of the delicate little flower of the same species (_G. verna_ ); while the white blossoms of the grass of Parnassus, and the frailer white of the _dryade a huit petales_, and the modest waxen flowers of the _Azalea procumbens_ and the _airelle ponctuee_ (_Vaccineum vitis idaea_), tempered and set off the prevailing blue. |
