Low shrubs, sprawling to erect, often with coppice shoots sprouting from lignotubers after fires
Leaves ovate to narrowly lanceolate, longer in coppice shoots, sessile; leaf margins ciliate to lanate; minute stipules seldom visible; bud leaf colleter soon shrivelling to a black cone or lost
Flowers each in a spikelet, solitary and terminal in an involucre of 5-12 bracts at end of a short stipe, spikelets on an elongate peduncle, old stipes persistent; ciliate bracts with a prominent midrib and often several parallel veins, bases of two lowest bracts forming an inverted shallow bowl around narrowed tip of stipe; floral receptacle often with fleshy warts or transverse wrinkles and a rib below each sepal
Calyx: sepals free, narrowly ovate to triangular, whitish to bright red; sepal midrib prominent, often with parallel lateral veins
Corolla white to bright red; petals free, clawed, glabrous, often with small crests next to ovary
Stamens free; anther thecae either united or partly free; pollen grains tricolporate
Nectary and scent either 0 or not recorded
Ovary inferior to half-inferior; locules 2 (also 3 and very rarely 4 or 5), wall between locules sometimes incomplete; ovules 1 or 2 per locule, or 0, pendulous, or ovules sterile as dark flakes in spongy tissue filling locule; styles terete or distally furrowed, rarely partly to fully free, erect or apically diverging
Fruit little known, at least sometimes indehiscent

Welcome to Biodiversity Advisor 2.0!
Biodiversity Advisor, developed by the South African National Biodiversity Institute (SANBI) and its Data Partners, is a system that will provide integrated biodiversity information to a wide range of users who will have access to geospatial data, plant and animal species distribution data, ecosystem-level data, literature, images and metadata.
The integrated information comes from our much-loved Botanical Database of Southern Africa (BODATSA) also known as Plants of Southern Africa (POSA), Zoological Database of Southern Africa (ZODATSA), Biodiversity Geographic Information System (BGIS), SANBI's institutional repository (Opus) and others.
The system is still under development, so you may find a few bugs/issues. If you do, please report it via the error reporting button available in various sections of the website or provide us with any useful feedback you may have via the ‘Give us feedback’ option available in the sidebar menu. You can create a free account for yourself by clicking on the user profile icon which will take you through to the login page. Here you can choose the ‘Create an account’ option or simply fill in your details if you have an account already. Having an account on Biodiversity Advisor will provide users with free access to biodiversity resources.
In future, Team SANBI will be able to log in using their day-to-day login details, BGIS users will be able to use their existing accounts and details, and general users will be able to log in using their LinkedIn profile, but for now you will need to create an account.
