Cotyledon undulata

Fresh seed of Cotyledon undulata (Oudtshoorn) available here:

Synonym: Cotyledon orbiculata var. oblonga. The description of "Rolling Edge" , a variant of  Cotyledon orbiculata var. orbiculata also seems to fit the plants here discussed however.

I prefer to use the name Cotyledon undulata, even if it is just for the sake of communication. It makes it easier to distinguish between different forms as long as they are somewhat geographically separated

Close to our farm south of Oudtshoorn both a flat leaved fairly tall form of Cotyledon orbiculata var. spuria  and Cotyledon undulata grow in close proximity (500 meters or so) to each other and in similar habitat. There are no hybrids detected although they seem to keep some distance from each other. I hope to take some  pictures under a microscope of  the flowers of both kinds for comparison.

Cotyledon undulata seed

Seed of Cotyledon undulata under a microscope compared to millimeters on a  ruler.  Because of their small size the seeds should rather be planted on top of the (sandy) soil. I do cover them however with a  +- single layer of coarse sand.
