Themeda triandra spikelets16 (9604098200)

Description:

Summary[edit] Description: Flowerheads are spatheate panicles, containing clusters of 7 spikelets enclosed by a spathe. Clusters consist of a central fertile spikelet with a long thick (0.4-0.5 mm wide) black awn, surrounded by 6 male or barren, awnless spikelets; 4 are unstalked (6-12 mm long) and 2 stalked. The upper half of the glumes of the unstalked spikelets vary from hairless (mostly northern and western NSW) to densely covered with glandular hairs (most common in south east NSW). These very hairy samples were photographed at Mt Annan in Sydney. Date: 12 July 2011, 12:10. Source: Themeda triandra spikelets16. Author: Harry Rose from South West Rocks, Australia.
