Do we owe our existence to the Protea Atlas Project?

Almost twenty years ago, Esme Morris noticed a healthy Cape Flats Silkypuff (Diastella proteoides) shrub growing on the edge of Meadowridge Common. Recognizing it as a rare and threatened species*, she did a bit of research on the plant and alerted Tony Rebelo who was co-ordinating the impressive Protea Atlas Project that ran from 1991-2006 under the auspices of the South African National Biodiversity Institute (SANBI).
This is the entry that appeared on the Protea Atlas website:
"Mrs Esme Morris discovered some plants of Diastella proteoides while on a walk in the Meadowridge Common. Not only did she correctly identify the plant, but she also dug out an article from the Constantiaberg Bulletin of October 1988, written by Grahame Wilson of the Constantia Captrust. It appears that in 1988 some plants of the Flats Silkypuff were protected by a few strands of barbed wire on the common off Faraday Drive and Schoolside. Today only three plants survive on the common, one of which has had a load of tar dumped on it.
"It is not easy to preserve our flora, especially when the plants are sprawling mats with flowers no bigger than a fingernail. It is only through getting the local people interested that we can conserve the indigenous flora on our commons. Perhaps we need a 'Friends of the Meadowridge Common!'"

Winter flowers on Meadowridge Common


Probably the Common's most important species, this rare and endangered member of the Protea family is the Flat's Silkypuff, Diastella proteoides.
It was once abundant on the Cape Flats, but most of its southern populations have been destroyed and small remnant populations remain - one on our Common! (Click here for the some history of its discovery.) The plant carries a status of 'Vulnerable' in the Red Data book and is likely to be upgraded to Endangered as its northern habitats (it occurs on sandy flats as far north as Mamre) are developed.
The Flats Silkypuff flowers erratically throughout the year, but mainly from July to February and our bush is starting to flower now. Find it near the storyboards on the Common.
The plants do not produce nectar - pollination is by beetles and flies that visit the flowers to feed on pollen. The round white seed is produced two months after flowering. Each flowerhead may produce a single seed, which is bigger than the entire flowerhead. These seeds are collected by ants, which bury them in their nests. Here they are safe from fire and rodents. Germination only occurs after fire. (Info from the Protea Atlas Webpage)


Tortoise Berry, Nylandtia spinosa, belongs to the milkwort family (Polygalaceae) and starts flowering in June. By the end of the month it will be covered in purple flowers. A good plant to grow in your sandy garden! It is named after Pierre Nylandt, a Seventeenth Century Dutch botanist. The species name is derived from the Latin, spinosa, meaning spiny.
