38 . Alpine Piants. 
Coronilla minima (5.W. Europe). 
This plant requires a sunny place, more than 
the above, in a warm sandy soil. 
Coronilla vaginalis (Europe, etc.). 
This species will do in a similar position and 
soil to Coronilla minima, but a little grit should be 
added when planting. 
Cortusa Matthioli and C. M. grandiflora (N. Europe and Asia). 
Plant on the edge of the bog-garden, or in any 
fairly damp place where a little shade can be ob- 
tained, in peat, loam, and leaf-mould. 
Cortusa pubens (Transylvania). 
This species requires a little more care; it is 
well suited for a small rock-garden close to the edge 
of a path, where it will be dry during winter. In 
early spring it will be found that the crowns have 
risen out of the ground in the course of the preceding 
winter ; they must, therefore, be pressed firmly back 
into their places, and a little top-dressing of peaty 
loam added. 
Cortusa villosa (Hab. ?). 
Treat like Cortusa pubens. 
Corydalis tuberosa (syn. cava) albiflora (Europe). 
This comparatively little-grown plant is very 
useful on account of its early flowering, delicately 
graceful habit, and refined colour. It is of the easiest 
culture, thriving in almost any soil or position. The 
plant dies down after flowering, and is easily in- 
creased by breaking the hollow tubers into small 
pieces in the months of June or November.
