FOUR NEW SUBTRIBES: ALLOLEPIINAE, JOUVEINAE, KALINIINAE, AND SOHNSIINAE IN THE CYNODONTEAE (POACEAE: CHLORIDOIDEAE)

Allolepis, Jouvea, Kalina, and Sohnsia are small (only Jouvea contains two species), often overlooked genera that are morphologically and genetically isolated within the tribe Cynodonteae. We present a molecular phylogeny using sequence data from seven plastid markers (ccsA, ndhA intron, ndhF, rpl32-trnL, rpoC2, rps16-trnK, and rps16 intron) and the nuclear ribosomal internal transcribed spacer regions (ITS 1 & 2). Since Allolepis, Jouvea, Kalinia, and Sohnsia do not align within any of the 21 existing Cynodonteae subtribes, we describe Allolepiinae, Jouveinae, Kaliniinae, and Sohnsiinae as new. In addition, we provide descriptions, habitat, distribution, and comments for each subtribe.
