Mexico and the West Indies, and even into Mada

therefore, assuming a definite opinion that JParnassiaj Sauvagesia, 



and Za vr a dia should be united into the same order, I would 



venture to suggest whether our pretty little English Grass of Par- 



nassus, so foreign in many respects in its appearance, may not 



he looked on in some sort as a European and temperate repre- 



sentative of the tropical Sauvagesice and Lavradice.
