A New Species of Scutellaria (Lamiaceae) from Kyushu, Southern Japan

Abstract

A new species of Scutellaria (Lamiaceae), S. kujuensis Kadota & Mas. Saito, is described and illustrated. Scutellaria kujuensis is similar to S. shikokiana Makino but the former differs from the latter by having: triangular-ovate cauline leaves with dark reddish purple bottom surfaces and with dark green upper surfaces variegated along midribs and lateral veins; the absence of bracteoles near basal parts of pedicels; the presence of glandular hairs on corollae, calyces and pedicels; convex lower lips of the corollae with purple spots only on the middle lobes and the early blooming (June). Scutellaria kujuensis is endemic to the Kujū Mountains, Kyushu, southern Japan.
