Magnoliopsida
Pectis prostrata Cav.
EOL Text
The development of roads and highways has created ideal habitats for Pectis prostrata. Its range appears to be expanding along the coasts of Florida; it was discovered in Louisiana relatively recently. It can be expected to spread along the Gulf Coast and perhaps northward along the Atlantic Coast as well. Autogamy has apparently assisted P. prostrata to spread rapidly as suitable new habitats have become available.

Pectis prostrata (Spreading cinchweed) is a summer blooming annual plant of the genus pectis. The development of roads and highways has created ideal habitats for pectis prostrata. Its range is expanding along the coasts of Florida, it was recently discovered in Louisiana. It is expected to spread along the Gulf Coast and also northward along the Atlantic Coast. Autogamy has assisted pectis prostrata to spread rapidly as suitable new habitats have become available.[1]
