Chorisochora (Acanthaceae) in Somalia: the new species C. chascanoides
Tóm tắt
The new species Chorisochora chascanoides is described from limestone cliffs in north-eastern Somalia. Three species were previously known in Chorisochora, two in Yemen (Socotra) and one in NE South Africa and Botswana. On morphological grounds the Somali species is believed to be most closely related to the two species on Socotra. The pollen of the new species is of the Ecbolium-type, in agreement with the other species of Chorisochora.
