Oriental arborvitae

Although generally accepted as only member of its genus, it has been suggested that the closely related species Microbiota decussata could be included in Platycladus, but this is not widely followed. Other fairly close relatives are the genera Juniperus and Cupressus, both of these genera being graft-compatible with Platycladus. In older texts, Platycladus was often included in Thuja, but it is only distantly related to that genus. Differences from Thuja include its distinct cones, wingless seeds, and its almost scentless foliage.
