lar and smooth, but not branching : the leaves are sharply serrate, 

 on short petioles, and hirsute : the flowers are axillary, one or two 

 together, on peduncles shorter than the leaf: calyx smooth, with 

 broad triangular segments: corolla very large, blue; the segments 

 triangular, divided by a line : the fruit obliges the peduncle to bend 

 down with its weight. It is a native of the northern parts of the 

 island, flowering in Julyv 



There are varieties with single and double purple, and with single 

 and double white flowers; with single and double pale-red flowers; 

 and with striped flowers. 



The fifth species has a perennial root: the stems are from two to 

 three feet in height, upright, stiff, hairy, angular, the angles membra- 

 naceous, putting out a few short side-branches: the leaves resem- 

 bling those of the great nettle, but rather shorter and broader, alter- 

 nate, ovate,- cordate, pointed, hairy, deeply toothed, sometimes 

 having two or three lobes; petioled, except the upper ones, which 

 are sessile : the peduncles are alternate, axillary, trifid, and three- 

 flowered. The number of flowers, however, varies from one or two 

 to three, four, and even five; they are large and nodding. It is a 

 native of most parts of Europe, &c. flowering in July and August. 



There are varieties, with single and double blue flowers, with 

 single and double white flowers, and with single and double pale 

 purple flowers. 



The sixth species has the whole plant very smooth; the root pe- 

 rennial, white, fusiform, the thickness of a finger, and branched: the 

 stems are few, erect or ascending, simple, round, a foot high, leafy 

 all over, annual, terminated with one handsome flower, but without 

 scent, nodding a little, with sometimes one or two flowers more 

 from the upper axillas: the leaves are irregularly scattered, sessile or 

 on very short petioles, ovate or sublanceolate, short and sharply 

 serrate: sometimes a few of the leaves, and at others all of them, are 

 in threes : the corolla is two inches in diameter or more, very deep 

 blue, with numerous blue veins; elegantly pear-shaped before ex- 

 panding, and at first green. It flowers in June and beginning of- 

 July, and is a native of Siberia.
