Phyllostegia glabra
Phyllostegia glabra, known as smooth phyllostegia, is a Hawaiian endemic shrub or perennial herb in the mint family, rarely grown outside conservation settings. Its variety lanaiensis is endangered and may be extinct, so it is not a practical garden plant.
Phyllostegia glabra is a species of flowering plant in the mint family known by the common name smooth phyllostegia. It is endemic to Hawaii.
Known varieties include Phyllostegia glabra var. glabra and P. g. var. lanaiensis, the latter being a perennial herb with dentate leaves, often reddish or red-veined, and white flowers, occasionally tinged with purple, distinguished from P. g. var. glabra by its shorter calyx and narrower leaves.
