Cycas clivicola

Also known as "The Cliff Cycad" this plant derives its name from the Latin clivis, a cliff, and the Latin suffix, -cola, a dweller, in reference to the fact that this plant grows in limestone cliffs.

Although widespread and abundant, this species remained unnamed until the late 90's. It was previously thought to be a form of C. pectinata or C siamensis.

It grows in limestone outcrops, throughout southern Thailand. Plants are most often rooted in clefts and crevices in near-vertical cliffs, in full sun and often with no soil at the roots.
