8. POGOGYNE MULTIFLORA. Benth. Luh., p. 414. 



Raised from seed collected by Mr. Hartweg, in " fields 

 about Sonoma," in California. 



A dwarf labiate annual, emitting a strong smell of horsemint, 

 when bruised, owing to the leaves, which are perfecly smooth, 

 except near the base and when they are young, being copiously 

 marked with small pits connected with cystsof volatile oil. Tlie 

 stems are from 4 to 5 inches high, four-cornered, brittle and 

 smooth, branching from the base. The leaves are IJ inch 

 long, including tlie stalk, which in tlie lowest forms one half, 

 oblong, and very blunt ; occasionally they have a minute tooth 

 upon the edge. Tlie flowers are of a jiale lilac colour, and are 

 arranged in spiked verticillasters at the end of the shoots. Each 

 is rather more than \ an inch long, with a 4-lobed bilabiate limb, 

 whose segments are blunt and of nearly equal size. The anthers 

 project a little beyond the orifice ; the hairy style is longer than 

 the upper lip. The bracts are linear-lanceolate, about as long as 

 the corolla, and fringed with long hairs. 



It is a hardy annual, growing freely in any rich soil, and like 

 most Californian plants of the kind may be sown at different sea- 

 sons. It flowers in Auguj-t and September if sown in May. 



A rather pretty dwarf spreading species, requiring plenty of 

 moisture in summer to keep it in bloom, which is produced for 

 a long time.

9. Clematis tubulosa. Turczaninow, Bulletin des Nat. de 

 Mosc. xi. 148. 



Received from Dr. Fischer in 1846. 



This is the most remarkable Clematis in our gardens. It 

 forms a branching upright herbaceous plant, with stiff angular 

 purple downy stems, and great, smooth, shining, ternate leaves, 

 of a pale bright green, the larger leaflets of which are 3 inches 

 long and 2^ broad, bordered by coarse mucronate serratures. 

 The flowers appear in sessile corymbs in the axils of the leaves, 

 on stalks about H i'lch long ; they are about an inch long when 

 full blown, of an intense blue, and extremely handsome.
