Abstract

A remarkable new Premna species from Myanmar, P. grandipaniculata Y.H.Tan & Bo Li (Lamiaceae), is here described and illustrated. It differs from all known congeneric taxa by having huge complicated panicles which have tertiary branches formed by spike-like thyrses. In Premna, such a spike-like thyrse is found in P. bracteata and P. interrupta, but those species can be easily distinguished from P. grandipaniculata by their habit, indumentum, leaf size and inflorescence structure.
