South African Plants!

[Joshua Pollins]

Desperate for help identifying a couple of plant species from our project in South Africa recently (North-west province). We looked at the antimicrobial properties of some species and found exciting results. Would be very grateful fro some help!

2nd one could be a periwinkle! I could be wrong though!

The 1st and 3rd photos are both Pellaea calomelanos, a native fern in the Brake family (Pteridaceae).
The 2nd photo is Madagascar Periwinkle (Catharanthus roseus). Clearly, a cultivated plant.
The 4th photo remains unidentified, though the leaves do remind me of certain plants in the Mallow Family (Malvaceae).
