 The flora is rich, as varied and peculiar as the insect world, 

 which in great part it supplies. Here we find endless variety

 some specialties in the entomological line. Sand clearings with 

 a few scattered plants, here and there a short pine tree, form 

 the asylums of Fossorial Hymenoptera and yield Fine thing
