Nicotiana glauca
Nicotiana repanda
Nicotiana glauca is registered as an invasive plant in the United States (www.invasives.org). It can form monodominant stands due to high seed set and germination success. It was originally introduced from Argentina to Mexico, thence to the United States and worldwide (T. H. Goodspeed 1954). Siphaulax glabra Rafinesque is an illegitimate, superfluous name for this species.

Nicotiana repanda occurs along the Gulf Coast and in Texas in southern, central, and the eastern edge of west Texas, in adjacent Mexico, and on the island of Cuba. It overlaps in distribution with N. plumbaginifolia but is easy to distinguish from that species by its pandurate (fiddle-shaped) cauline leaves and longer, thinner flowers.
