places where they will have a good depth of soil in the fissures 

 to grow in, and abundant moisture in the growing season. Both 

 the shrubby and herbaceous species may be propagated by divi- 

 sion, and are most accommodating as to soil and situation. 



P. fruticosa {Jerusalem Sage). — This is a noble and striking 

 plant in any position. It reaches the height of 3 or 4 feet, the 

 stems stout and woody below, the branches downy. The leaves 

 are large, egg-shaped, woolly on the under side, >vrinkled and 

 hairy above. The flowers are in large, dense, whorl-like heads 

 at the extremities of the stems and branches, yellow, appearing 

 in June, July, and August. Native of Sicily and Calabria. 

 Very suitable for naturalising, and for associating with shrubs. 



P. herba-venti. — This is an erect, handsome, herbaceous 

 species, growing about 2^ or 3 feet high. The stems are 

 stout and much branched. The leaves are oblong, egg-shaped, 

 boldly toothed, and hairy below, smooth and shining above. 

 The flowers in the same style of inflorescence as the last are 

 red, and appear in July, and last for a month or two. Native 

 of southern Europe. 



P. purpurea {Piu-ple-flowei-ed P.) — Another suffruticose species 

 growing 2 or 3 feet high. The leaves are broadly egg-shaped, 

 densely woolly on the under side. The flowers are purple, in 

 the characteristic style of inflorescence, and appear in June, 

 July, and August. Native of southern Europe. 



P. Russelliana {RusselVs P.) — This species is herbaceous, 

 forming bold masses of strong stems about 3 feet high. The 

 leaves are broadly egg-shaped, deeply heart-shaped at the base, 

 wrinkled on the upper side, and hoary on both sides. The 

 flowers are dusky purple, appearing in July and August. Native 

 of the Levant. 



P. tuberosa {Tiibej-ous-rooted P.) — An herbaceous plant grow- 

 ing 3 or more feet high, with strong, erect, slightly-branched 

 or simple stems. The leaves are broadly heart-shaped, slightly 

 toothed, roughly \mnkled, and clothed with stifiish down below, 

 and above with rough, short, thickly- set hairs. The flowers are 

 reddish purple, appearing in July, lasting till late autumn. 

 Native of Siberia and the south of Europe. 



There are several other species, both herbaceous and shrubby, 

 worthy of a place wherever naturalising may be engaged in, or 

 where extensive shrubberies exist, and with the exception of 

 P. Lychiiitis and JVissolii, all are capable of existing in any part 

 of the British Islands. 



Physostegia. — A genus closely related to Dracocephahwi, and 

 comprising species which nearly all were formerly included in 

 that family. They are handsome showy plants, adapted for
