Morphology General Habit
Prostrate to ascending ephemeral or short-lived perennial, stems to 0.7 m long
Morphology Leaves
Leaf base attenuate into ill-defined petiole, tip obtuse or subacute
Morphology Reproductive morphology Inflorescences
Flowers always bisexual. Fruiting pedicels up to 3.5–8 mm long, fairly stout, usually curved Inflorescences mostly axillary, with at least some, often most, flowers in umbels of 3 or more
Morphology Reproductive morphology Flowers Calyx
Sepals 1.8–2.6(–3) mm long, whitish, sometimes flushed pink, mauve or yellow
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 5; filaments with wide base
Morphology Reproductive morphology Flowers Gynoecium Carpels
Carpels 5, sculptured forms spiny-papillose or winged.
Distribution
N1; C1; S1 Eritrea, Ethiopia, south to South Africa, west to Nigeria, east to Indo-China.
Ecology
Sea level to 1430 m.
Note
Material from South Africa approaches G. africana in habit and flower size which is larger than in northern material. Only the stamen count gives a reliable separation in that area and perhaps the complex needs more detailed study. The Somali material is var. pharnaceoides. Many collections from eastern Arabia and adjacent areas of Iran and Pakistan have winged mericarps and are placed in var. alata M. Gilbert.

Note
The plant is often subject to a blight (Exobasidium gisekiae Allesch.) which renders it pink or wine-red in colour.
