, rarely pinnately compound
, petiolate
; stipules entire or sometimes lacerate
, persistent
or caducous
; leaf blade
margin
dentate
, serrate or rarely entire; veins pinnate. Inflorescences terminal
or axillary
, cymose
or racemose, rarely 1-flowered. Flowers generally bisexual
, actinomorphic
or more rarely zygomorphic, bracteate
; pedicels articulated. Sepals (2-4) 5(10-15), free
or more rarely united
, imbricate or valvate
. Petals (3-) 5(-8), mostly free, clawed to sessile, contorted or imbricate. Stamens 5-10 or numerous
; filaments
generally free and persistent, or anthers
sessile; anthers basifixed
, longitudinally dehiscent
or poricidal
; staminodes present or not, sometimes persistent, awl-shaped
, spatulate
, or petaloid
, sometimes connected into a tube
. Gynoecium (2 or) 3-5(-15) -carpellate, gynophore
present or rarely absent; ovary superior, entire or deeply lobed
, generally long styled; placentation basal, axile
or parietal
, rarely laminar
; ovules 1 or 2 or numerous per locule; stigma entire or sometimes shortly divided
at apex. Fruit fleshy
or non-fleshy, generally a septicidal
capsule, rarely a nut with accrescent
sepals or a drupe, or separating into up to 15 blackish drupelets
on a colored
accrescent receptacle. Seeds endospermic
or non-endospermic, winged
or not; germination phanerocotylar
or cryptocotylar
; embryo usually straight, more rarely curved
.
About 27 genera and ca.
500 species: tropical
zones, mainly in the Neotropics; three genera and four species (one endemic) in China.[1]
Genus Ochna
Small trees
or shrubs
. Stipules small, intrapetiolarly united
, deciduous; leaf blade
simple
, margin
generally serrate, rarely entire; secondary veins curved
upward, especially near margin, not joining in a submarginal
vein
. Inflorescences branched, sometimes corymbose
. Sepals (4 or) 5, completely enclosing floral
bud, margins entire, often accrescent
and colored
in fruit, persistent
. Petals 5-12, yellow or rarely orange or white, contorted. Stamens numerous
, 2- or more whorled
; filaments
short or elongate
, persistent; anthers
poricidal
or more rarely longitudinally dehiscent
. Ovary deeply lobed
, 3-15-locular; ovule 1 per locule; style gynobasic
, slender; stigma generally slightly lobed. Drupelets
3-10(or 15), black, inserted
on accrescent receptacle. Seed non-endospermic; embryo straight or curved.
About 85 species: mainly in tropical
Africa, a few species in tropical Asia; one species in China.[2]
