Phenology
Flowering time: Nov. to Feb. Flowering Dec. to April.
Ecology
Anthoxanthum ecklonii subsp. natalense is associated with the Drankensberg Foothill Moist Grassland (Mucina & Rutherford 2006). Plants grow abundantly on mud islands in streams below waterfalls. The area is characterised by mudstones and sandstones of the Tarkastad] Subgroup and the Molteno Formation (Karoo Supergroup) as well as intrusive dolerites of the Jurassic age. Usually in moist places such as stream sides and on grassy mountain slopes, extending to forest margins.
Note
Anthoxanthum derived from the Greek word ‘anthos’ meaning flower; ‘xanthos’ means yellow, referring to the yellow-green mature spikelets. The species epithet ‘ecklonii’ is in honour of Christian Frederick Ecklon (1795 – 1868) German-born South African apothecary and plant collector. The word ‘natalense‘ denotes the origin of the subspecies, collected from Kwazulu-Natal, South Africa. Anthoxanthum ecklonii subsp. natalense is similar to A. ecklonii subsp. ecklonii. Both subspecies have glumes with keels scaberulous and lower lemma sparsely hairy, but they differ in a number of characters as summarised in Table 1. Resembles Anthoxanthum odoratum, which has the lower lemma shorter (3.0 – 3.5 mm long), dark brown and densely hairy.

Native to:

Cape Provinces, Free State, KwaZulu-Natal, Lesotho, Malawi, Northern Provinces
