Distribution
Southern Africa; one species.
Morphology General Habit
Dioecious or rarely monoecious pubescent shrubs to small trees
Morphology Leaves
Leaves alternate, petiolate, entire, penninerved, 1.4 – 2.5 times longer than wide, membranaceous to chartaceous
Morphology Leaves Stipules
Stipules persistent, membranaceous, margin entire, ciliate
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 5; filaments free to fused for c. 1/2 of their length; anthers longitudinally dehiscent
Morphology Reproductive morphology Flowers Calyx
Sepals 5, not accrescent
Morphology Reproductive morphology Flowers Corolla
Petals 5, slightly shorter than sepals in staminate flowers, half as long as the sepals in pistillate flowers
Morphology Reproductive morphology Flowers Disc
Disc in staminate flowers annular, irregularly crenate to almost lacerate, membranaceous to chartaceous; disc in pistillate flowers annular, finely crenulate, membranaceous to chartaceous
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 3-locular, glabrous to densely pilose; ovules anatropous
Morphology Reproductive morphology Flowers Gynoecium Pistillodes
Pistillode 3-lobed
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigmas capitate
Morphology Reproductive morphology Flowers Gynoecium Style
Styles free, bifid to base
Morphology Reproductive morphology Flowers Pedicel
Pedicels articulate above base; articulation practically invisible before abscission
Morphology Reproductive morphology Flowers Pollen
Pollen subprolate; exine tectate perforate to microreticulate
Morphology Reproductive morphology Fruits
Columella 2.5 – 5 times longer than its narrowest width Fruit 3-lobed
Morphology Reproductive morphology Inflorescences
Inflorescences axillary, solitary to fasciculate, staminate sometimes on short densely bracteate inflorescences
Morphology Reproductive morphology Seeds
Seeds 2 per locule, ecarunculate, rounded triquetrous, undulate to shallowly rugose
Morphology Reproductive morphology Seeds Cotyledons
Cotyledons equal, broad, thin, longer than radicle, much wider than radicle.
Morphology Reproductive morphology Seeds Embryo
Embryo longitudinally almost straight
Morphology Reproductive morphology Seeds Endosperm
Endosperm copious, deeply invaginate independently of the outer seed coat sculpture
Note
Hoffmann (1994) correctly observed that Andrachne ovalis does not fit well into either Andrachne or Leptopus and is different from Phyllanthopsis (Andrachne phyllanthoides and A. arida). Its position as a lineage separate from Meineckia subgen. Petaliferae (Andrachne cerebroides and A. gracilipes) is an unexpected result of the molecular phylogenetic analyses (Vorontsova et al. 2007).
