Tliis species has been treated variously as a member of Chloris or of Tetrapogon. As brought out in i-arlier discussion, the two genera are very closely related and must be somewhat arbitrari- ly separated. Essentially, Tetrapogon regularly has more than one basal fertile floret, vyhile Chloris has just one. A sampling of nineteen specimens, from different locations in southern Africa, showed seventeen with a single fertile floret and two \\ath two fertile florets. Because.
