Cymose-flowered Dodder. Pl. parasitical. 
Culi. The species are all parasitical, or rather epiphytical 
plants; the hardy species grow very well on ivy, or any small 
shrub. All the species may be grown by sowing the seeds in 
at the side of any soft wooded plant. 
T It is not known whether the following genus belongs to the 
present order.

ceous, fibrous; cells 1-seeded.? Seeds large.—A climbing 
shrub, with stiff, elliptic, acute, glabrous leaves, and axillary,

Calyx bracteate, imbricate, deeply 5-parted. Corolla tubular,

centiferous on both sides ; cells many-seeded.—Branched, erect, 
shrubs. Leaves alternate, or 4 in a whorl. Flowers lateral,

and in the dissepiment being placentiferous.

p. 34. Branches hairy. Leaves crowded, lanceolate-linear, ses-

neath. Flowers lateral towards the extremities of the branches, 
sessile, crowded, upright, almost concealed among the leaves. 
Bracteas acute, keeled, hairy, longer than the calyx. Corollas 
rufescent. This plant bears a very great affinity with Convél- 
vulus, and especially with Convólvulus emotheroides, which is 
probably also a species of Rétzia.
