Revision as of 16:31, 18 September 2019

Plants perennial; cespitose, sometimes rhizomatous. Culms 40-400 cm, erect. Leaves not aromatic; sheaths open; ligules membranous, truncate, ciliate; blades flat. Inflorescences terminal, ovoid or corymbose panicles, with elongate rachises and numerous ascending, spikelike branches; branches usually more than 10 cm long, with unequally pedicellate spikelet pairs, spikelets homogamous and homomorphic; disarticulation below the glumes. Calluses short, blunt, pilose, with fine hairs, hairs often exceeding the spikelets. Glumes membranous to coriaceous; lower glumes broadly convex to weakly 2-keeled, without raised veins; lower florets sterile; upper florets bisexual; upper lemmas entire and unawned or bidentate and awned from the sinuses; anthers 2 or 3. Pedicels free, x = 19.

Discussion

Miscanthus is a genus of approximately 25 species. Most of the species are native to southeast Asia; a few extend into Africa. Some species hybridize with Saccharum, from which Miscanthus differs in its non-disarticulating branches and unequally pedicellate, rather than sessile-pedicellate, spikelets.

The five species found in the Flora region are all grown as ornamentals because of their large, plumose panicles and striking growth habit. They flower in late summer to fall. The differing chromosome numbers within Miscanthus sinensis and M. sacchariflorus are associated with morphological differences in Japan, but it is not known if this is true for cultivated plants.

Key

1 Callus hairs 2-4 times as long as the spikelets. > 2
2 Spikelets 4-6 mm long; upper lemmas unawned or the awns not exceeding the glumes Miscanthus sacchariflorus
2 Spikelets 2-2.8 mm long; upper lemmas awned, the awns 9-13 mm long, exceeding the glumes Miscanthus nepalensis
1 Callus hairs from shorter than to twice as long as the spikelets. > 2
3 Culms few together or solitary; basal leaves with reduced blades, only the cauline leaves with long blades; panicles loose, with 2-5 branches Miscanthus oligostachyus
3 Culms densely tufted, forming large clumps; many basal leaves with long blades; panicles usually with more than 15 branches. > 4
4 Spikelets 3.5-7 mm long; blades 6-20 mm wide; rachises 1/3 – 2/3 as long as the panicles Miscanthus sinensis
4 Spikelets 3-3.5 mm long; blades 15-40 mm wide; rachises 3/4 – 4/5 as long as the panicles Miscanthus floridulus
