In this numerous genus there are other spe- 

 cies that may equally deserve cultivation. 



The first has a stiff, slender, woody stem, six 

 or seven feet high, sending out many branches 

 the whole length : these and the leaves are 

 hairy ; the calyxes also very hairy : hut the 

 branches and leaves, when further advanced, 

 become naked : the leaves are large, of a light 

 green colour, sessile, with many nerves : the 

 flowers are produced at the ends of the branches, 

 on naked peduncles : the corolla is white, and 

 soon drops off; and the petals, according to 

 Linneeus, are tinged with purple on their edges ; 

 the stamens yellow ; and the calyxes, before they 

 unfold, three-cornered in their appearance. It is 

 a native of Portugal, flowering in June and July. 



The second species rises with a strong woody 

 stem, to the height of five or six feet, sending out 

 many erect hairy branches : the leaves are lan- 

 ceolate, acute, thick, dark green above, and 

 white beneath, very glutinous in warm weather; 

 but, according to LinnEeus, wrinkled, green on 

 both sides, and scarce visibly hairy ; the petioles 

 becoming purple at the base : the flowers are 

 produced at the ends of the branches upon long 

 naked peduncles, branching on their sides into 

 smaller ones, each sustaining one large white 

 flower with a hairy calyx. It flowers in June 

 and July, and is a native of Spain. 



The third grows to the height of five or six 

 feet, with a strong woody stem, sending out 

 many hairy branches : the leaves are smooth on 

 their upper side, but veined on their under, on 

 short foot-stalks which join at their base, where 

 they form a sort of sheath to the branch : the 

 corolla is white, the size of the officinal Poppy : 

 the germ has ten swellings: stigma sessile, with- 

 out any style. It is a native of Spain, &c. It 

 flowers from June till August. 



Mr. Curtis objects to the propriety of the name 

 /ada/i/J'erus, as it is not the plant from which 

 ludanum is produced, though in a warmer cli- 

 mate it affords a gum of a similar kind. 



There are varieties with large white flowers, 

 and a purple spot in the middle of the petal, and 

 with entire white flowers. 



The fourth species has a shrubby stem, 

 branching to a large bushy head, three or four 

 feet high : the branches villose : the leaves are 

 not at all nerved, ending in a point, a little 

 flexuose in the disk, ending at the base in coa- 

 lescent sheathing petioles, or rather obovate- 

 spatulate; the lower more connate, and in a 

 manner sheathing : the calyxes hairy, with sub- 

 cordate leaflets: the petals purple, eniarginate or 

 obcordate, quite entire and concave. It is a 

 native of Spain. 



The fifth species is an upright shrub, three or 



four feet high: the branches are round, ash 

 coloured, angular at top, the younger ones dotted 

 with yellow: the leaves are petioled, opposite, 

 lanceolate, very white, scarcely soft, without 

 veins, obtuse, flat, abont an inch in length: the 

 peduncle terminating, compound, white; sup- 

 porting three or four bright yellow flowers, which 

 appearin June and July. It is a native of Por- 

 tugal. 



There are varieties with numerous leaves and 

 sulphur-coloured flowers, and with yellow flow- 

 ers with purple spots in their bases. 



The sixth rises with a slender stem, from three 

 to four feet high, sending out many hairy 

 branches from the bottom upwards : the leaves 

 are very dark green, in warm weather covered 

 with a glutinous sweet-scented substance: the. 

 peduncles, which come out at the ends of the 

 branches, are long, naked, and sustain many 

 white flowers, rising above each other; their 

 calyxes are bsrdered, and end in sharp points. 

 It flowers from June to August, and is a native 

 of Narbonne. 



There is a variety with olive-shaped leaves 

 and sulphur-coloured flowers. 



The seventh species is branching, diffused, a 

 foot and half high and more: the stem and 

 branches round, and somewhat villose: the 

 leaves from broad stem-clasping, petioled, first 

 spatulate, then ovate or lanceolate, somewhat 

 acute, wrinkled, sometimes waved, roughish, 

 thickish, quite entire, viscid, closely set on both 

 sides and round the edge with white hairs of 

 different lengths, some simple, others branched 

 or headed, scarcely visible to the naked eye : 

 peduncles one-flowered, terminating the last 

 leafy twigs, erect and villose : the flow ers of a 

 rose purple-colour : these appear in June and 

 July, and the seeds ripen in September. It is a 

 native of the Levant. 



This is the species from which the drug called 

 ladanitm is procured. 



The eighth has a shrubby stem, branchino- 

 from bottom five or six feet in height : much re- 

 sembling the fourth, but differing in the branches 

 being tomentose, not hairy : thcleaves pa!er,soft, 

 horizontal, sessile, by no means eitherpetioled or 

 sheathing, broad-lanceolate, mostly three-nerved : 

 the flowers long from the branches, of a bright 

 purple colour: it is a native of Narbonne, &c? 



In the ninth, the branches are weak, slender, 

 woody, spreading horizontally : it is seldom more 

 than two or three feet in height: the peduncles 

 and calyxes are covered with a thin wool : the 

 flowers are of a purple or white colour, appear- 

 ing in June and the following month. It is a 

 native of Portugal. 



The tenth has a slender, smooth stem, c<s-
