Abstract:A new combination，Peristrophe brevispicata (I． Darbysh．)Y． F． Deng et Z． P． Hao，is proposed．
Key words:Acanthaceae;Africa;Dicliptera;Peristrophe
Peristrophe Nees is a genus of Acanthaceae
consisting of 25 －40 species and distributed in tropical
and subtropical regions of the Old World． It differs
from the closely related genus Dicliptera Juss． by the
mechanism of capsule dehiscence，which are non-
elastic in Peristrophe but elastic in Dicliptera［1－3］．
Darbyshire ＆ Vollesen［4］ merged Peristrophe with
Dicliptera and transferred eastern African Peristrophe
species to Dicliptera． But recent molecular analysis
does not support this view and indicated that
Peristrophe is more closely related to Hypoesthes than
Dicliptera［5］． The recently described African species
Dicliptera brevispicata I． Darbysh． possesses the non-
elastic capsules and should be transferred to
Peristrophe［4］． Therefore， a new combination，
Peristrophe brevispicata (I． Darbysh．)Y． F． Deng et
Z． P． Hao，is proposed herein．
