Cult. These shrubs are hardly worth cultivating, except in 
general collections. They will thrive well ina mixture of loam 
and peat, and ripened cuttings will strike root in sand under a 
hand-glass, in heat. `

Ovary 3-celled, each cell containing 8-ovulz. Style 3-furrowed, 
and at length dividing into 3 parts. Berry 6-9-seeded, 3- 
pointed from the permanent styles.—A tree with serrulated leaves 
and terminal panicles of white, sweet-scented flowers. It is

Sepals 5 (f. 106.), permanent, concrete at the base. Petal 5, 
hypogynous, broadest at the base, furnished each with a scale 
on the inside, with the margins incumbent before expansion. 
Stamens 10 (f. 106. c.), filaments concrete into an urceolus at 
the base (f. 106. c.). Anthers versatile, erect, 2-celled, 
bursting lengthwise at the sides. Ovary 1-celled, con- 
taining a solitary, pendulous ovula, or 3-celled, the lateral cells 
empty. Styles 3, (f. 106. d.), distinct, crowned each by a capi- 
tate stigma (f. 106. d.) or connected almost tothe apex. Drupe 
1-seeded (f. 106. f.); seeds angular. Albumen fleshy or want- 
ing. Embryo linear, straight, central. Cotyledons linear, flat, 
leafy. Radicle superior, straight, terete, pointing towards the 
hylum, with an inconspicuous plumule.—Trees and shrubs with 
the younger branches compressed, and usually covered with im- 
bricate scales (f. 106.). Stipulas axillary, concave. Leaves 
alternate, rarely opposite, quite entire, smooth in most parts of 
the species and perhaps in all. Pedicels angular, gradually 
thickened. Flowers solitary, twin, or in fascicles, rising from 
axils of stipulaceous scales, small, white, or yellowish-green. 
This order has been separated by Kunth from Malpighiacee, on 
account of the petals being appendiculate, from the seeds being 
albuminous, and in the fruit being 1-celled from abortion, as 
well as from its peculiar habit. It differs from all the neigh- 
bouring orders in the appendiculate petals. From Marcgravia- 
cee, Guttifere, &c. in the leaves being stipulate.

ner of the feathers of a pen). Leaves feather-nerved (f. 106. g) 
with the nerves small, conniving at the apex. | : i
