 Haidy herbaceous perennials, with corymbose, apetalous 

 flowers ; calyx tubular, with the tube rather contracted at 

 the apex. Leaves palmate or lobed. Of very easy culture, 

 in common, but well drained soD. They are well adapted 

 for rockwork and planting near the front of borders. Easily 

 increased by divisions of the roots, and seeds. All here 

 described are hardy, except A. sibbaldiwfolia.

 simple leaves, and minute stipulas. Flowers few, in clusters. 

 They thrive in pots filled with a mixture of sand, loam, and 

 peat. Young cuttings will root in sand, with a bell glass 

 placed over them, in heat ; but by seeds, if they can be 

 procured, sown in a hotbed, is a preferable mode of in- 

 creasing the plants. They may be placed out of doors 

 during the summer months.
