Discussion
Lasiacis divaricata is a Caribbean species. Its range extends from Florida through the West Indies to Mexico, Panama, and northern Venezuela. In Florida, it usually grows in hammocks, but occasionally in pinelands. The whitish to brown upper florets are unusual in the genus.
Plants in the Flora region belong to Lasiacis divaricata var. divaricata, which differs from the other two varieties in having panicles with fewer spikelets and panicle branches that are usually reflexed.
Selected References
