|discussion=<p>Most plants of <i>Polystachya concreta</i> flower from August to December; some flower at other times of the year. In Florida, <i>Polystachya concreta</i> [<i>P. flavescens</i> (Blume) J. J. Smith] is pollinated by the halictid bee, Dialictus aff. creberrimus (G. J. Goss 1977b). The bee collects the detachable, starchy lip hairs (pseudopollen).</p><!--
--><p>An extensive list of synonomy is available (G. C. K. Dunsterville and L. A. Garay [1959]–1976, vol. 3), but after discussions with Phillip Cribb (pers. comm.), we suspect that the African and Asian synonyms represent different species (see also P. J. Cribb 1984). For this reason, we have excluded them from the list, even though some of them are often used for neotropical plants. Furthermore, <i>Polystachya concreta</i> is not as widespread in the Neotropics as formerly believed; it is absent from Mexico and Central America (J. T. Atwood, G. Carnevali F.-C., R. L. Dressler, pers. comm.).</p><!--
--><p><i>Cranichis</i> luteola Swartz and <i>Polystachya</i> luteola (Swartz) Hooker are not legitimate names.</p>
