SALICACEAE— was FLACOURTIACEAE—(MALPIGHIALES,
EUROSIDS I)
NUMBERS: 85 Genera, 800 species
GEOGRAPHY: pantropical
ECOLOGY: shrubs and small trees (understory in tropical forests, especially
sterambanks))
ROSID CHARACTERS: petals separate, androecium diplostemonous
CHARACTER COMMON IN MALPIGHIALES: pair of glands at petiole summit
CHARACTERS DIAGNOSTIC OF FAMILY:
Habit trees, spiny or not
Leaves alternate (or opposite), attached to thin twigs, with salicoid teeth (marginal teeth
with acropetal hemispherical glands)
Flowers inconspicuous, usua lly in axillary fascicles, or in panicles
Androecium of many stamens (or sometimes just a few)
Gynoecium superior (usually), compound
Fruit berry (or capsule or drupe); seeds arillate or woolly or not
Well-known in the literature as a trash-heap family. Nevertheless, the family hangs
together in the field and can be identified intuitively based on general appearance
with fair accuracy, especially if you see the parietal placentation. The molecular
phylogeny confirms the family as na tural if you include the willows and poplars. In
the above description I have included in parentheses the frustrating exceptions that
make this family infamous.
Examples - The Flacourtiaceae have no major economically important members, so the
examples are just a few genera you are most likely to see.
Casearia - common tree with axillary fascicles of stinky little flowers and prominent
lenticels
Xylosma - well-known as the armed flacourt - prominent thin spines th roughout the plant
other genera I have encountered: Abatia, Carpotroche, Has seltia. Hasseltiopsis,
Macrohasseltia
Salicaceae (Flacourtiaceae)

Salicaceae (Flacourtiaceae)
Casearia - the most commonly seen
Tetrathylacium
The hagila tree, Oncoba spinosa --- prominent in the
African savannah
Oncoba – also an
ornamental, edible pulp
