1. New Albums and some changes
The latest genera Albums added to the Operation Wildflower Site are the ones on Tritoniopsis, Melianthus and Metalasia. This means that photos and stories of plants belonging to these genera already on the Site have been moved from the more general Albums called Bulbs and Shrubs into their own new Albums under Genera.
There is a genus Album in every case where enough material has been accumulated to warrant a stand-alone grouping of photos and stories. There are now more than 160 such Albums on genera of South African plants. The biggest ones (most photos) belong to the genera Crassula, Euphorbia, Pelargonium and Aloe. Keep watching, more will be added! If there is no genus Album yet on the plant you are looking for, check under Types or the Search Box.
In order to access all items on a plant of interest, the Search Box should be used, entering the botanical name of the plant. Most photos and stories on a particular plant are likely to be posted under Genera, (or if there are only few of them, in the conglomerate categories under Types). Habitat, Regions or Parks and Gardens may also contain some material on a species searched for, showing in the list generated when using the Search Box. The latest Regions Album is the one on the Langkloof. A new Parks and Gardens Album for the Caledon Wildflower Garden has also been created from existing material.

This grassland species is regarded as the most valuable grass in sourveld. Themeda triandra grows abundantly when the veld is in good condition.
The grass is green to blue-green, tufted, and is often flushed with pink. As it ages, the colour deepens to red. The spikelets (grass flowers) form wedge-shaped clusters, sometimes hairy, which tend to hang down.
The species name tri (three) and andr (man) is Greek, referring to the three male spikelets surrounding the bisexual spikelet in each cluster.
Themeda is fire resistant, increasing with frequent burning provided it is not overgrazed. The grass is palatable, and an important and well-known grazing grass.
The grass grows in regions with average to high rainfall, and is common in altitudes between 1300 and 3000 meters above sea level.
Themeda triandra occurs only in southern Africa, though it is one of 18 Themeda species occurring across the world.
Interesting fact: The long awns (long bristle-like projections) of the spikelet twirl when wet, and drive the seed into the ground.
Flowers: between October and July.
Height: between 300mm and 1500 mm
Uses: grazing; indicator of good veld conditions
