the presence of lime, does wonderfully well at the Linnaea, while the 

 lime-loving species planted there are not so brilliant. That is why we 



established in 1895 at the summit of the Eochers de Naye (6000 feet 

 high) another rock-garden of pure limestone only, on which we culti- 

 vate with success the plants of the highest points, and more especially 

 of the limestone mountains. There we own sixteen acres, which extend 

 over the two slopes of the mountain, nortih and south, from the top of 

 the Eochers de Naye to scarcely ten minutes from the station of the 

 railway leading from Territet-Montreux and the Hotel de Naye. This 

 explains the great popularity of the Eambertia and why we have from 

 1100 to 1200 visitors every summer, although up there the summer 

 lasts scarcely more than two and a-half months. 



At the Eambertia the slope is much steeper than at the Linnaea; the 

 view is more extensive, comprising a part of the alpine chain from 

 Mont Blanc to the Jungfrau. The Alpine and Iceland Poppies are 

 there mixed, and have given birth to a crowd of divers forms and tints. 

 Geranium argenteum and G. cinereum reproduce themselves sponta- 

 neously on every rock, and the flower of the Edelweiss there attains 

 considerable size and purity of down. But what prospers above every- 

 thing are Campanula pulla and Linaria pallida, w^hich form veritable 

 carpets invading all our rocks. 



The University of Lausanne has established at Les Plans, above 

 Bex (3600 feet), a little alpine garden which serves for the study of 

 alpine flora by the students at Lausanne. This garden is named La 

 Thomasia.

But it is in wall-culture that we Swiss have perhaps the superiority 

 over other peoples. In 1860 Boissiee made his famous wall at Val- 

 leyres, in which he cultivated Saxifraga longifolia, S. florulenta, S. 

 media, S. tomheanensis, S. Vendelli, S. caesia, S. retusa, &c., side by 

 side with Haherlea rkodopensis, Alyssum pyrenaicum, Valeriana longi- 

 flora and the rock Primulas. 



We established in 1884 in our garden at Plainpalais a wall of tufa 

 stones which we garnished with saxatile plants of all kinds and which 

 was soon well covered. There flourished Phyteuma comosum and P. 

 humile, Campanula Rai?ieri, C. excisa, C. petraea, C. velutina, C. 

 Wanneri, C. macrorhiza, the Primulas pedemontana and Portae, An- 

 drosace helvetica, A. tom&ntosa, A. ciliata, A. vitalia7ia, A. pub^scens 

 and A. glacialis, every variety of Saxifrage, the Hedraeanthuses, 

 Omphalodes Luciliae, &c. 



When I transported my plants to Floraire I built there a wall with 

 two sides, one looking to the south, the other to the north, and intro- 

 duced into all the crevices betw^een the stones all the saxatile flowers 

 capable of succeeding in our climate, and I had very satisfactory results 

 with all the Saxifrages of the groups Kabschia, Euaizoonia and Dacty- 

 loides, with the Hedraeanthuses, Androsaces, Dianthus, Silenes, 

 Lrabas, Petrocallis, Campanulas, Antirrhinum Asarina, A. glutinosum, 

 and A. sempervirens, Valeriana saxatilis and longiflora. Aethionemas
