1 . Crassula Coccinea ; Scarlet-flowered Crassula. Leaves 

 ovate, plane, cartilaginous-ciliate, connate-sheathing at the 

 base. Stem reddish, jointed, about three feet high, dividing 

 at top into many irregular branches ; flowers at the ends of 

 the branches in close umbels ; corolla funnel-shaped, ere,ct, 

 with a pretty long tube cut at the top into five parts, of a fine 

 scarlet colour ; leaves so closely opposite as to appear to be 

 in two rows. It flowers in July or August. Native country 

 unknown. All the hardy species of this genus, are propa- 

 gated by cuttings, during any of the summer months. These 

 cuttings should be taken off about a fortnight before planting, 

 and laid in a dry place, that the wounded part may heal over ; 

 they should then be each planted in a small pot of light sandy 

 earth, and plunged in a moderate hot-bed, allowing them but 

 little water. In aboutsix weeks they will put out roots.and 

 begin to grow, and should have a large share of air admitted 

 to them, that they may be gradually inured to bear the open 

 air, into which they should be taken, and placed in a shel- 

 tered situation until autumn, when they must be removed into 

 a dry airy glass case, where they may enjoy as much sun as 

 possible, and be defended from the wet and cold. While they 

 are abroad in dry warm weather, during the summer months, 

 they should be gently watered twice or thrice a week, but 

 should have very little water in winter, lest it rot their stems. 

 They require no artificial heat, but merely to be secured 

 from the frost and wet. 



2. Crassula Cymosa ; Cyme-bearing Crassula. Leaves 

 linear, cartilaginous-ciliate, connate-sheathing ; stem shrub- 

 by, cyme terminating. Stems a span high, erect, smooth, 

 annual ; roots perennial ; leaves opposite, smooth, cartila- 

 ginous-scaly about the edge. 



8. Crassula Flava ; Yellow -flowered Crassttla. Leaves 

 plane, connate-perfoliate, even ; flower corymb-panicled, 

 fascicled, but each pedicelled ; petals yellow, erect. 



4. Crassula Pruinosa ; Frosted-leaved Crassula. leaves 

 subulate, frosted scabrous ; flowers corymbed ; stem shrub- 

 by, a foot high, dichomotous ; the small branches round, 

 blood-red, covered, as is the whole plant, with the resem- 

 blance of a crystalline hoar-frost. 



5 Crassula Scabra ; Rugged Crassula. Leaves opposite, 

 spreading, connate, scabious, ciliate ; stem scabrous back- 

 ward. Stem weak, succulent, about a foot and a half high, 

 divided at top into small branches ; flowers in small clusters 

 at the end of the branches, small and herbaceous : the corolla 

 is so deeply divided, as to make it doubtful whether it be 

 monopetalous or pentapetalous ; leaves green, thick, succu- 

 lent. It flowers in June and July. The stem and leaves 

 are every where rough with whitish bubbles. 



6. Crassula Perfoliata ; Perfollate Crassula. Leaves lan- 

 ceolate, sessile, connate, channelled. The stem is upright, 

 rising ten or twelve feet high, if not broken or injured ; but 

 it requires support, being slender, and the leaves very weighty: 

 the flowers terminate in large clusters, of a white herbaceous 

 colour, with short tubes, and the brim is cut into five parts ; 

 they appear in July. The flower-stalk is thick and succulent, 

 generally turning lirst downwards, then upwards again, 

 almost in form of a syphon. 



7. Crassula Fruticulosa. Leaves opposite, subulate, acute, 

 spreading, somewhat recurved ; stem shrubby. 



8. Crassula Tetragona ; Sc/uure-leaved Crasmla. Leaves 

 subulate, somewhat incurved, obscurely four-cornered,spread- 

 ing; stem erect, arborescent, rooting. Stem arborescent, two 

 or three feet high, erect, even-surfaced, reddish, branched; 

 leaves longer than the internodes, about the thickness of a 

 goose-quill, acute, green, smooth, opposite in cross pairs so

as to form two regular rows ; flowers very small, white ; in a 

 terminal trifid much-branched cyme ; antherae purplish. 



9. Crassula Ramosa ; Branching Crassula. Leaves subu- 

 late, plane above, connate-perfoliate, even-surfaced, spread- 

 ing very much; peduncles elongated ; flowers cymbed. Stem 

 a foot high, filiform, smooth, leafy, branched at bottom ; 

 branches alternate, smooth, rufescent ; leaves longer than the 

 internodes, entire. 



10. Crassula Obvalla. Leaves opposite, sublanceolate, 

 sharp-edged, approximating. Stem three or four inches high, 

 closely branched from the base. 



11. Crassula Cultrata ; Sharp-leaved Crassula. Leaves 

 opposite, obovate, subcultrate, oblique, connate, quite entire. 

 It rises about two feet high, with a weak succulent stalk, 

 which sends out many irregular branches. The stalk which 

 supports the flowers rises from the top of the branches, and 

 is from four to six inches long, putting out several side- 

 branches, which grow erect, and are terminated by large 

 clusters of small greenish flowers, which never expand, but 

 appear in June and July. If the cuttings of this species be 

 planted in a border of light earth, they will put out roots, 

 and may afterwards be taken up and potted, to be sheltered 

 in the winter. 



12. Crassula Cotyledon ; Tree Crassula. Leaves roundish, 

 fleshy, dotted on the upper surface ; stem arboreous. The 

 whole plant is smooth. Stem two feet high, very thick, erect, 

 branched near the top ; branches grayish or reddish, cylin- 

 drical, fleshy, leafy ; flowers numerous, inodorous, at first 

 white, but afterwards rose-coloured. 



13. Crassula Pinnata ; Wing-leaved Crassula. Leaves pin- 

 nate ; stem arboreous ; panicle axillary, shorter than the 

 leaves ; flowers red. Native of China.

 three or four inches high ; flowers yellowish-red. It flowers 

 in May and June. 



15. Crassula Dichotoma ; Forked Crassula. Stem dicho-

 side, golden-coloured within, with a blood-red heart-shaped

 green, dichotomous at top, scarcely a palm in height, flower- 

 ing in June and July.
