On the cover Some plants have it all—great form, interesting flowers, ease of culture, splashy color, and seasonal variation. Such are the few cultivated succulent dorstenias, which are perenially popular and fascinating pachycaul succulents with a bizzare flowering structure, which normally bears both male and female flowers. Often self fertile, a few are eager to volunteer as seedlings without any provocation. Not so with our cover feature, a Somalian plant long circulating under only it’s locality as Dorstenia sp 'Taba’a Gap'. It turns out to be unique in the genus for having male and female flowers on separate plants, a feature that delayed its introduction for many years after its discovery and now distinguishes it as a valid new species. It’s easy to see why, even un-named, this plant attracts attention. Our cover, a photo by Out of Africa’s Mike Massara, reveals this “new” dorstenia in fall color, just before the leaves drop for a winter rest. And in this issue it finally receives a name: Dorstenia lavrani.
