Appearance and leaves
They are small, evergreen trees or shrubs . The leaves, which are mostly alternate and arranged in two rows on the branches, are divided into a petiole and a leaf blade. The leaf blades are simple with a whole to toothed or serrated leaf margin. There are small, heart-shaped stipules .
Inflorescences and flowers
The small, dense, cylindrical, catkin- like racemose or spike-like inflorescences are axillary. Bracts and bracts are present between the flowers . The small flowers are hermaphroditic and greatly reduced. There are four to six bracts or they are missing, the petals are missing. There is only one stamen . Two or three carpels are a top permanent ovary grown. In each flower there is a style with two to three stigmas. There is a discus .
Fruits and seeds
The three-lobed capsule fruits usually contain one, sometimes three, seeds; however, they look like berries . The oil-containing seeds have an aril or a sarcotesta .
Systematics
The Lacistemataceae family was established by Carl Friedrich Philipp von Martius . These taxa were formerly classified in the Salicaceae or in the earlier family of the Flacourtiaceae as the tribe Lacistemeae.
In the family Lacistemataceae there are only two genera with about 14 (up to 27) species:
