Novelties in Hyptidendron (Hyptidinae – Lamiaceae) from Brazil: A new species and a rediscovery

A new species, Hyptidendron roseum , from the Chapada dos Veadeiros region, Goiás state, is described and illustrated. It can be distinguished from its congeners by the combination of inflorescences composed of a unilateral cymose structures, sessile to subsessile leaves, a ring of trichomes in the throat of the calyx tube, and a dense indumentum of white uniseriate trichomes covering much of the plant. The new species is compared with similar species such as H. unilaterale and H. albidum . New specimens of another species, H. unilaterale , formerly known only from the type, were identified in herbaria and collected in the field. Photos in vivo of this species are provided for the first time, accompanying a full description and an illustration. We assess its conservation status and comment on its distribution, ecological aspects, and identification.
