Flowers 5 mm long, in short axillary racemes of 1–3 (‒5); corolla pink to purple, rarely white; pedicel puberulent, 3‒8 mm long, to 13 mm at fruiting. Pods flat, segmented, 5‒12 (‒18) mm long and 2–3.5 mm wide, comprising 3–5 (‒7) articles, covered with minute hooked hairs; upper suture straight, lower suture constricted between the articles; articles nearly quadrate, reticulately veined, separating when ripe. Seed yellow, reniform to orbicular c. 1.2 × 1.7 mm.
Grona triflora: terminal leaflet obcordate, obtriangular, or obovate, 2.5–10 mm long and 2.5–10 mm wide, base cuneate, apex truncate, slightly emarginate; silver blaze absent.
Grona heterophylla: terminal leaflet broadly elliptic or broadly elliptic-obovate, 10–30 mm long and 8–15 mm wide, base obtuse, apex rounded or nearly truncate, often emarginate; silver blaze on midrib common.

G. triflora is widespread throughout the world tropics and subtropics, extending into continental regions that experience extremes of hot and cold. Attempts have been made to define the limits of indigineity, but these are somewhat blurred by encroachment of areas of naturalization.
A component of short (grazed) native and sown pastures, where it can form up to 50% of the herbage. Creeping mat can provide good ground cover during the wet season, especially in mown or closely cut uses.
Maintains a stable ground cover in association with stoloniferous grasses under constant heavy grazing or regular mowing such as under plantation crops and in lawns.
Considered to have medicinal properties for treating dysentery, rheumatism, fever, jaundice, stomach ache, skin problems, wounds and ulcers (in particular in India and China).
Found on a wide range of soil types, including acid, high Al soils.
G. triflora largely occurs in moist, well-drained soils in the humid and subhumid tropics and subtropics with annual rainfall above 700 mm; it behaves as perennial under well-distributed rainfall and as an annual in the strongly seasonally dry tropics. While it survives mid-season dry periods, leaf drop serves as a survival mechanism in even moderately dry periods.
It is well-adapted to warm environments, being found largely between the Tropics, although it has been found about 28° S in Australia and possibly at similar latitude north of the equator in Iran. Leaves are readily frosted, but plants recover with the onset of warmer conditions.
Very shade-tolerant, being more dominant than grasses under the shade of shrub canopies. Persists under plantation crops in the Pacific.
Flowers and sets seed over a long period making seed production difficult.
Resistant to heavy grazing and frequent mowing or cutting.
Pastures containing G. triflora are rarely burned with a hot fire because of low fuel loads, but the plants can re-establish from rootstocks or seed.
Guidelines for establishment and management of sown forages.
G. triflora is rarely sown commercially. It spreads naturally through seed in dung or by adhering to the coats of grazing animals.
Responds well to P (and S).
Compatable with prostrate grass and legume species.
Grasses: Found in association with many grasses including Axonopus spp., Bothriochloa pertusa, Cynodon spp., Ischaemum timorense, Heteropogon contortus, Paspalum notatum.
Legumes: Alysicarpus vaginalis, Grona heterophylla.
No information available.
Occurs in most land uses in regions to which it is well adapted such as pastures, roadsides, lawns. It is found throughout the tropics.
May be considered a weed in cultivation and in lawns.
14–18% CP.
Very palatable to all classes of livestock, including poultry.
No reports of toxicity.
In most situations G. triflora produces so little dry matter, it is unlikely to be seriously considered in any sown pasture or forage program. Nevertheless yields of up to 4 t/ha DM have been recorded.
Widespread and persistent under heavy grazing and so likely to markedly improve the diet of livestock on heavily grazed native pastures such as those found on communally owned and managed grazing land.
2n = 22.
No commercial seed production due to limited or no demand, low growth habit and the extended period over which flowering and seed set occurs.
