FLORA AND SYLVA. 



the fine A. glutinosum from the moun- 

 tains of Spain, flowering with a long 

 season and very freely. Then follows the 

 whole group of Arabis and nearly all 

 the Arenarias, with Aster alpinus, the 

 complete list of Aubretias, and all the 

 rock-loving Campanulas, of which ma- 

 crorrhiza, elatines, elati?ioides, Raineri, 

 excisa, garganica, muralis, ccespitosa, 

 pusilla, petrtea^nd Cenisia are the best. 

 All the Cerastiums are useful, and the 

 free -growing Corydalis lutea with its 

 paler relative ochroleuca. Most of the 

 Dianthus and all the Drabas,the Edrai- 

 anthus, and the Erinus may also be in- 

 cluded in the list, with the pretty little 

 Fairy Forget-me-not (Eritrichium na- 

 num),which cannot be kept alive in any 

 other way. Several of the Erodiumswill 

 serve, and amongst the Erysimums such 

 kinds as pumilum, pulchellum, purpu- 

 reum , Kotschyanum&nd IV itt?nci7ini. The 

 Edelweiss [Leontopodium alpinum) does 

 well in such crevices, as do also Gypso- 

 philarepensaxid most of the Rock-roses 

 (Helianthemums), for which, however, 

 a certain depth of soil is necessary. Add 

 also Hypericum coris and reptans, and 

 all the Iberis and Linarias, with Litho- 

 spermumpetrceum and olcefo Hum ^Lych- 

 nis Lagascce among the Campions, and 

 Micromeria rupestris, the Moehringias, 

 and Omphalodes Lucilice and lusitanica. 

 The Alpine Poppy (Papaver alpinum) 

 will flower in its season, with Phy teumas 

 comosu7n andhumile, and of the Cinque- 

 foils, Potentillas alpestris, caulescens, ru- 

 pestris, and tridentata. All the Primu- 

 las of the groups auricula and viscosa 

 maybe relied upon for colour in spring, 

 and of the Soap worts, Saponaria cccspi-

tosa, lutea, pulvinaris ,2cs\d that brilliant 

 little trailer ocymoides. The Saxifragas of 

 the Aizoon and Kabschya groups, such 

 as longifolia, cotyledon, aretioides,ccesia, 

 and media, yield a rich variety of form. 

 Sedums and Sempervivumswill grow in 

 the driest nooks, and most of theSilenes 

 and Teucriums, the shrubby Vella 

 pseudo-citisusand spinosa,a.nd Veronicas 

 Allien ii, ccespitosa, canescens, fruticu- 

 losa, orientalis, saxatillis, and spicata, 

 with Viola cenisia, completes a list which 

 only serves to give an idea of the wealth 

 of material to hand. 



For the north or shaded side of 

 our wall should be used ferns, but not 

 Ceterach, Nothochlce?ia, 

 W( oodsia,ox Cheilanthes, 

 which do best upon the 

 sunny side. Of flowering plants there are 

 Ramondia, Haberlea, C/i?ysosplenium, 

 Saxifraga Huetti and cymbalaria, W ul- 

 fenia, and Primula capitata. I mention 

 in this list only those kinds that have 

 done well on our own wall, and for 

 English gardens especially it might be 

 lengthened by including many plants of 

 difficult culture in a moist climate, un- 

 less kept from excessive wet by a place in 



such a wall-garden as I have described.

Floraine, Geneva. 

 Wild Flowers. — " He who has taken lessons 

 from Nature, who has observed how the flowers 

 flush forth from the brightness of the earth's 

 being, as the melody rises up from the moved 

 strings of an instrument ; how the quick fire 

 of their life and their delight glows along the 

 green banks, where the dew falls the thickest 

 and the low mists of incense pass slowly through 

 thetwilightof the leaves ; hewho haswatched 

 this will never take away the beauty of their 

 being to mix into meretricious glare or to feed 

 into an existence of disease." — J. Ruskin.
