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: but 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 pro- 

 duced at the ends of the branches, on naked peduncles: the corolla 

 is while, and soon drops off; and the petals, according to Linnaeus, 

 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 lanceolate, acute, thick, dark green above, and white beneath, 

 very glutinous in warm weather; but, according to Linnaeus, wrink- 

 led, green on both sides, and scarce visibly hairy; the petioles be- 

 coming 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, without any style. It is a 

 native of Spain, &c. It flowers from June till August. 



Mr. Curtis objects to the propriety of the name ladaniferiis, as it 

 is not the plant from which ladanum is produced, though in a warmer 

 climate 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 coalescent sheathing petioles, or rather obovate-
