of Chile, where it appears to be exceedingly common, and is called Semperviva, on 
account of the permanence of its deep azure flowers. It has long been known to 
botanists conversant with the Chilian Flora as a most desirable species to 
introduce, and repeated attempts have been made to secure it, but in vain, until 
seeds came into the hands of Mr. Frost, gardener to the Countess of Grenville, at 
Dropmore." Mr. Frost has been very successful in rearing it ; but the specimens 
exhibited by him at the Chiswick Gardens have not been free from that brownness 
in the lower leaves, and that partially unhealthy aspect, which are too common to

We owe our drawing to Mr. Glendinning, of the Turnham Green Nursery, in 
whose collection it flowered well last autumn, and where our artist obtained 
specimens. Mr. Glendinning writes us respecting it as follows " Its scarcity in 
collections is attributable to three causes ; viz., the sparing way in which it has 
hitherto been increased, the want of the true desideratum of culture, and the great 
difficulty attending its preservation during winter, I perpetuate it by division of
