Nertera depressa, from Southern America, is a dwarf 

 creeping herbaceous gem when profusely covered 

 with its bright little orange berry. I have seen it 

 at Bitton, amongst Mr. Ellacomb's hardy ferns, 

 whose fronds shelter and partially shade it, and else- 

 where flourishing out of doors ; and now plants can 

 be purchased for a few pence. 



Eritrichiim w0m*w, which inhabits many European 

 mountains, is amongst the brightest of Alpine gems. 

 It is said that its intense blue is approached only by 

 that of dwarf Gentians, whilst its azure hue is like 

 to that of a deep-blue sky, seen from its native hills. 

 It is found from the south of France to Carniola, in 

 stony places, fed by snow rills, at elevations of from 

 twelve thousand feet downwards. 



Just now Begonias named from the botanist 

 Begon, and of which several species have for a 

 considerable time been favourites attract particular 

 attention, and are very valuable in different kinds of 

 town-gardening. Already many brilliant varieties 

 from Peruvian Andes, of the group to which the 

 It. Veitchii, B. rosteflor. B. Clarkei, &c., belong, 

 though not know r n more than a few years in Eng- 

 land, are amongst the brightest ornaments in sum- 

 mer of many rock-gardens, and at other seasons also 

 of the conservatory. The first of those above-named 

 withstood in Mr. Veitche's garden a temperature 

 of 25 Fahrenheit, which, considering the elevated 

 region where it is native, led Sir Joseph D. Hooker 

 to expect, or at least hope, that it would stand outside
