There are many other species equally desening 

 of cultivation. 



The first has shrubby stems, from nine to 

 twelve inches high, branched, brown, somewhat 

 rugged from the remains of the leaves which 

 have fallen ofl": branches a little woolly : the 

 leaves are commonly in fours, but sometimes in 

 fives, ovate-linear, spreading, near the flowers 

 pressed close to the stem, the edges turned in and 

 ciliated, each hair terminating in a small round 

 gland ; the upper surface is fiat, the lower con- 

 cave and white: flowers hanging down one over 

 another all one way. It is a native of the 

 northern parts of Europe, flowering in July and 

 Aucustj but according to Linnneus, twice in the 

 year. 



It is not inferior to many of the foreign heaths 

 in the beauty and delicacy of its flowers. This 

 is distinguished from the other British heaths, 

 not only by the flowers growing in a Kind of 

 pendulous cluster on the tops of The stalks, but 

 by the leaves grow ing in fours, and forming a 

 sort of cross. 



The second species has a perennial woody root : 

 the stems shrubby, about a foot high, with op- 

 posite branches: the bark ash-coloured: the 

 leaves are linear, fleshy, spreading; abovesmooth 

 and shining, transversely wrinkled; towards the 

 end beset with a few scattered hair-like points; 

 beneath having a longitudinal furrow, which is 

 white from a woolliness apparent to the magni- 

 fier; the edge somewhat membranaceous, and 

 when viewed with the microscope appearing ser- 

 rulate : the leaves, when young, have three flat 

 sides, but when full grown are nearly flat: the 

 flowers arc in long clustered whorls terminating 



in spikes, ofa deep purple colour, sonorous when 

 struck; they come out from the sides of the 

 young shoots; those from the cud-shoots being 

 near each other, but scattered and bare; those 

 from the small lateral branches generally in pairs. 

 It is a native of the middle parts of Europe, 

 flowerino from June to August. 



The third has twisted, trailing .stems : the 

 branches between scoreil and angular, light 

 reddish brown ; the more slender shoots ash- 

 coloured, all lateral, to seven or more rising from 

 the same point in the manner of an umbel ; 

 when beginning to flower, gradually tapering 

 towards the end : the leaves are linear, soniew hat 

 like those of (ir, bowed sideways, smooth, but 

 not glossy, somewhat pointed, when magnified 

 appearing to have distant serratures on the edge, 

 which is bent in ; u|)per surface sxrcen, slightly 

 elevated in the middle; under whitish, convex, 

 with a smooth furrow running along it, longer, 

 and sometimes thrice as long as the corolla, and 

 crowded so close as to conceal the younger shoots : 

 the flowers roundish, on long slender pedvuieles, 

 from the sides of the branches, beginning Ironi 

 below the middle, and extcnduig to the ends, 

 continuing on, in the cultivated plants, till the 

 next season. It is a native of Britain. 



The fourth species is an upright shrub, grow- 

 ing tothe heightof six feet, with upright branches 

 covered with a white nap : the leaves are very 

 abundant, upright, smooth, almost awl-shaped, 

 covering the branches, wrinkled when dry : the 

 flowers very numerous, on the middle of the 

 branches, so that the later leaves are above them ; 

 they are on branching peduncles, forming a 

 panicle. It is a native of the South of Europe, 

 flowering from Februarv to May. 



The fifth is an upright rigid shrub, with 

 an ash -coloured bark : the leaves are in threes 

 or fours, linear, obtuse, somewhat rugged on the 

 edge: the flowers terminating, two or three, 

 subsessile. It is a native of Spain, flowering iu 

 April and May. 



The sixth species has the stem the height of a 

 man : the leaves are in fours or fives, spreading, 

 obtuse, sribbous at the base: the flowers purplish. 

 It is a native of the South of Europe, ilowering 

 from June to November. 



The seventh has the branches whitish, and 

 anirular: the leaves are in fours, seldom in fives, 

 an3 even : the flowers lateral, and of a purple 

 colour, simple, coloured, lanceolate, acute, 

 shorter by half than the corolla: style twice as 

 long as the corolla: stigma entirely simple: 

 it resembles the mult'iflora, but the corolla is 

 absolutely ovate ; the branches angularand white. 

 It is a native of the South of Europe, flowering 

 from March to May.
