Of this genus it is impossible to give any account: Most <lb xmlns="http://www.tei-c.org/ns/1.0" />authors at present are in the habit of making <del xmlns="http://www.tei-c.org/ns/1.0" rendition="#s">the</del> plants from <lb xmlns="http://www.tei-c.org/ns/1.0" />remote localities distinct if they have a slight difference in <lb xmlns="http://www.tei-c.org/ns/1.0" />appearance: it is my opinion however in this genus in particular <lb xmlns="http://www.tei-c.org/ns/1.0" />that soil & climate will make the same species vary so <lb xmlns="http://www.tei-c.org/ns/1.0" />much that it can scarcely be recognized.
