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, normally bearing both male and female flowers. Often self fertile, a few are eager to volunteer as seedlings without any help at all. Not so with our cover feature, a Somalian plant long circulating under only its locality as Dorstenia sp Taba'a Gorge. 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 unnamed, this plant attracts attention. Our cover, a photo by Out of Africa's Mike Massara, reveals leaves of this "new" dorstenia in fall color, just before they drop for a winter rest. And in this issue it finally receives a name: Dorstenia lavrani.
