Fynbos structural triad
Also known as: fynbos triad, Cape structural plants
The three plant families whose adaptive radiations together define the structure of fynbos vegetation in the Cape Floristic Region of South Africa: ericas (small evergreen heath shrubs), proteas (large shrubs with iconic flowerheads), and restios (rush-like graminoid plants in the grass layer). Each of the three has radiated into hundreds of mostly-endemic species in the Cape — together producing one of the most biodiverse Mediterranean-climate floras on the planet.
What this is
Three plant families whose simultaneous radiations defined the structure of fynbos:
- Ericas ([[erica]]) — ~660 species in [[cape-cod|the Cape]]; small evergreen heath shrubs in the mid-layer
- Proteas ([[protea]]) — ~330 Cape species; the large-headed iconic shrubs of the canopy layer
- Restios ([[restio]]) — ~330 Cape species; rush-like graminoids in the grass-and-sedge layer
Each layer is filled by a different family that radiated into hundreds of mostly-endemic Cape species — together producing a fire-adapted Mediterranean-climate shrubland with a per-area plant diversity that exceeds tropical rainforest.
Why this cluster
Fynbos cannot be understood without all three families; missing any layer changes the vegetation’s structure and function. The triad is one of the textbook examples of plant adaptive radiation in a Mediterranean-climate biome — and it produced a flora dense and distinct enough that [[cape-cod|the Cape]] was named one of only six floral kingdoms on the planet (alongside Boreal, Paleotropical, Neotropical, Australian, and Antarctic).
