HABIT Perennial; caespitose. Then if the mulch is burnt in late winter while the soil is still moist, then the seeds will germinate as the soil warms up in the spring. Palea absent or minute. T. triandra seedlings develop relatively slowly following germination. Asia-tropical: India, Indo-China, Malesia, and Papuasia. The twisted awns are relatively easily removed from the fertile spikelets and the caryopses are usually retained within the dark, hairy glumes (Glume - the empty bracts at the base of a grass spikelet; usually two glumes are present).

It grows predominantly in grassland and open woodland communities. )Stapf =Anthistiria ciliata var. Lower glume oblong; 1 length of spikelet; coriaceous; dark A well filled caryopsis will be 75% dark brown when ready for harvest and so when all the mature seed and seed heads are dark brown the optimum harvest time has passed. AVH is a collaborative project of the state, Commonwealth and territory herbaria, developed under the auspices of the Council of Heads of Australasian Herbaria (CHAH), representing the major Australian collections. Approaching optimum harvest time is associated with a change in crop colour from greenish to yellowish brown. Fertile lemma linear; hyaline; without keel; 1 It is therefore best to eliminate weed problems before sowing this grass. In southern Australia weed control in late winter/early spring appears to be critical in the survival of newly established plants. - kangaroo grass, red grass, rooigras - Africa (from Morocco to KwaZulu-Natal), Asia (from Yemen to Japan to Maluku), Australia, New Guinea Themeda trichiata S.L.Chen & T.D.Zhuang - Guangxi, Yunnan, Hainan Themeda unica S.L.Chen & T.D.Zhuang - Anhui, Zhejiang In total, there are 27 recognised Themeda species with both annual and … Themeda triandra has a wide distribution. smooth, or tuberculate; glabrous, or pubescent, or pilose. Themeda triandra is a perennial tussock-forming grass widespread in Africa, Australia, Asia and the Pacific. If a forage harvester has been used, then drying a large mass of material sometimes proves difficult. Spikelet callus hairs red. Life form: Grass/ Tussock. The mulch is spread evenly on the ground immediately after harvest, or up to winter and left for about 6 months for the seeds to drop out and presumably penetrate the soil because of the hygroscopic (Hygroscopic - responds (twists or opens) to moisture changes) awns. Older leaves tend to have a red/brown appearance. . non Hack. callus linear; 2–3 mm long; 2-toothed.

Forage harvesters have also been used to successfully harvest kangaroo grass seed when the harvested material containing the seed is to be spread as a mulch rather than for the preparation of pure seed samples.
