rounded or cordate at the base, more or less glabrous on the 

 surface, woolly and white on the subface. The leaves are, it 

 seems, disposed, mostly, in tufts at the tips of the shoots. From 

 among these arise, in May and June, an abundance of woolly 

 scapes, which attain more than 1 ft. in height, and bear com- 

 pound umbels of yellowish white flowers. The flowers indivi- 

 dually are small, but their number is very great. " It thrives 

 equally in peat earth, or common soil, best in a damp situation, 

 and may be increased by cuttings of its well-ripened shoots, 

 struck in peat and sand in an almost exhausted hot-bed." E. 

 compositum " was found by Douglas on the rocky gravelly banks 

 of rivers in New Albion." [Bot. Reg., July.)

An extremely beautiful variety, cultivated as the R. caucasi- 

 cum in the Gla.sgow Botanic Garden, and in some other collec- 

 tions in Scotland. " At this season (April, 1835), notwithstanding 

 a most unpropitious spring, our bushes [in the Glasgow Botanic 

 Garden], one of which is 2 ft. high, and 3 ft. in diameter, have 

 the extremities of their fine leafy branches terminated with a 

 cluster of large, beautiful, straw-coloured flowers." Leaves 

 elliptical-lanceolate ; above, dark green and glabrous ; beneath, 

 rust-coloured, from the presence of a reddish yellow, very short, 

 abundant down. [Bot. Mag., July.)

 24. The Theophrasteac£'<2', consisting of Theophrasta, Clavij«, 

 Jacquin/a, and Leon/a, constitute a small group, intermediate 

 between ik/yrsineae and Sapotece, being distinguished from the 

 former by their many-seeded fruit, leafy cotyledons, anthers 

 bursting on the side that is outward in relation to the flower, 

 and by the presence of appendages to the corolla, which are 

 alternate with the stamens, and which are to be regarded as the 

 rudiments of a second series of stamens, Theophrast« agrees 

 with Clavij« in having its anthers bursting outwardly ; but it 

 differs in its bell- shaped corolla, in the ring-like crown enclosed 

 in this, and in the stamens being separate, not united into a tube, 

 as they are in Clavija. — D. Don.

Its leaves are oblong-spathulate or lanceolate, from 12 in. to 

 18. in. long, and 9 in. broad, borne crowdedly, or somewhat in 

 a whorled mode; they are green, smooth, toothed, the teeth 

 pointed, so as to resemble spines. Its flowers are produced in many- 

 flowered (about twenty-flowered rapemejs in the picture) racemes,
