This an old blog that I am reviving at the moment. My home made websites work well and I would like to continue with them. Blogger however is so easy to deal with now and saves a lot of time. I shall therefore place posts here and may transfer some to my other websites later that are better indexed for specific searches. The indexing/content of the old posts need to be improved - Will work on it bit by bit. You are welcome to leave comments - unfortunately I cannot reply to them as it causes Firefox errors.


Cotyledon undulata

Fresh seed of Cotyledon undulata (Oudtshoorn) available here:

Cotyledon undulata flowering in front of Echinocactus grusonii

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.
