 so diversified between the tropics, presents but a

 the garden after the gerania, malvacece, and

 we have six hundred species, and among them 

 several mimosas unknown till the last voyage of 

 captain Baudin ; and the terebinthacecz, a remark-

 trailing sumach, rhus toxicodendron, and the 

 upright poisonous ash, rhus radicans, whose
