Of this pretty Indian genus, of which ten species are re- 
corded in Mr. Thwaites’s ‘ Enumeratio,’ the present is, we be- 
- lieve, the first that has ever been -introduced alive to Europe. 
It was sent to us by our valued friend just. mentioned, in 1861, 
and was in great beauty in the month of June of the present 
year. It inhabits mountains in the central province of Ceylon, 
at altitudes of from 2000 to 4000 feet, and may be found to 
succeed even better in a temperate greenhouse than in a hot 
stove, where we have hitherto kept it. Its deeply-plaited leaves 
and humble growth remind one of those of our Primrose and 
Cowslip, but the young foliage is pale-coloured and deeply 
tinged with rose, while the flowers more resemble those of a 
Ranunculus, and the Natural Family to which it belongs (Dz/le- 
niacee) is next neighbour to that of the Crowfoots. A nearly- 
allied species to the 4. Walkeri is our A. wniflorum, figured in 
‘Icones Plantarum,’ vol. ii. p. 157; but the stem is there elon- 
gated, and the flower-stalks are appresso-pilose. A still more
