Dwarf, branched, rosette-forming perennials; short stems are often found with age but are generally obscured by clump-forming habit; roots slightly fleshy
Leaves opposite, 2-4 pairs per abbreviated branch, slightly connate at base, broadly triangular, varying from triangular in cross section to almost terete, up to 45 mm long, 20 mm broad, with distinct margins which are either smooth, white and cartilaginous or distinctly toothed, in some species teeth elongated and ending in a thin thread, surfaces smooth to variously tubercled or marbled and ribbed; dark green, reddish purple or rarely bluish
Flowers solitary, terminal, shortly pedicelled, sessile or subsessile, ebracteate, 30(50 mm in diameter; opening in afternoon, closing in evening
Sepals 5, unequal, often keeled and with membranous margins
Petals 2- or 3-seriate, free, linear, acuminate, obtuse or emarginate, often recurved, yellow to orange within, reddish copper outside and when withering, or rarely white
Stamens epapillate; staminodes 0
Nectary of 5 separate, crenate, yellow or greenish to dark brown glands
Ovary raised into a cone or subglobose on top; placentas axile to parietal; stigmas 5 or 6, filiform, erect
Fruit a 5- or 6-locular capsule, similar to Leipoldtia type but without closing bodies; appearing 10-locular and seedless: 5 empty hollows alternate with locules and seeds obscured by bent lamellae; valve wings firm, stout, connate with valves in their basal part only and standing rigidly above locules after opening of capsule; expanding keels ending in an awn, eventually capsules squeezed out by growth of new leaves
Seeds ± 1.5 mm long, reddish brown with minute, stalked protuberances
x = 9 (polyploidy)
Flowering late summer to autumn

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.
