Has. A very common weed, especially near the sea, in the 
greater part of tropical America, from Mexico to Guayaquil 
on one coast, and to South Brazil on the other. 
This species varies much in aspect, but the different forms 
can hardly be considered as distinct species. It constitutes 
alone a genus, with the habit and general character of the 
capitate Hyptides, but differing from them in the broadly cam- 
panulate calyx, and especially in the very singular form of the 
carpels, the margins of which are expanded into a membranous 
Wing, with the edges toothed and bent inwards, so as to give to 
the whole carpel a kind of boat shape. The flower is precisely 
that of a Hyptis. Bentham.
