D. lavrani is apparently unique in the genus as each plant produces only male or female flowers (so it is dioecious), so to produce seed, plants of both sex are needed. This contrasts with other dorstenias that have flowers of both sexes on the same plant, so that seeds are freely produced from just a single plant. It’s quite a recent addition to the genus since it was only discovered by John Lavranos in 1973. In habitat it grows in shady moss filled cracks in a limestone gorge - this gives a clue to the growing conditions needed in cultivation.
In addition to its ‘proper name’, it is also listed under various names such as DorsteniaTaba’a Gorge, Dorstenia species Mait Plateau and Dorstenia L&H 10341; these all relate to its habitat localities and collections from the Republic of Somaliland. You do need to ‘see before you buy’ or check on the origin of the plants if you can, as there seem to be some hybrids being miss-sold as D. lavrani.
These plants are from Mike Massara who named this plant in honor to the discoverer in 2008. |
