always some auidunt o£ moisture, but often in the summer 

 lieing saturated with water, (jwing to the melting- of iee 

 and snow on the peaks above them. Those I;eauties that 

 are so mueh prized in our gardens will generally thrive un 

 the roekery where the soil consists of sandy loam, with some 

 proportion of ealearcous matter, and the drainage is suffi- 

 ciently perfect to insure that there shall be no lodgment 

 of water in the winter season. As for the Eri/niiiiii in-i, a 

 poor soil and full exposure are tlie chief requisites. 



The Ijilliputian wallllower (A', jjii iiiiln iii) is a pretty 

 little Alpine with gie\'ish leaves, the whole plant rarelv 

 exceednig one inch in height, )jut Ijearing yellow llowers 

 of the same general chai'aeter as the plant before \ls. 

 This requires the best of care in its cultivation, and 

 should be seated amidst stones, both to insure continuous 

 moisture for its roots and to protect it from harm. 



The Rhcetian wallflower [E. rlnrHcinii) is a beautiful 

 little thing, worth a place on the choicest rocker}-. The 

 rock wallflower {E. ntpe-sl re) and the flne-leavcd wall- 

 flower {('Jie'iriiiitJniH tt'nirij-'uliii.s) maybe added to the Ijudget 

 as a couple of very choice subjects. The last named has 

 long narrow leaves and a short floAver-stem, bearing rather 

 large pale yellow flowers. 



The lance-leaved treacle mustard {J'L laiiccdhiluiii) 

 claims notice as a somewhat important plant, the names 

 it bears in the books being at least twelve in number. 

 It comes near to our Alpine wallflower, but, dilfcis in 

 growth and leafage. AVhatever its exact ])lace, it may 

 be made note of as a good rockery plant; it has two forms, 

 the mnjar and the iiiiaor, the last named being the best. 

 The flowers are of a lemon-yellow colour, very agreeably 

 scented.
