Several of these absentees grow in calcareous soil, or in open 

 (i. e., not shaded) muddy places, or in permanent ponds, which 

 have no counterpart in the region under consideration, and their 

 absence is thus easily explained; but in other cases the reasons 

 for this peculiar distribution are as yet obscure. 



Structure and adaptations. All but a few of the flowering 

 plants will fall into the classes of trees,. shrubs, woody and her- 

 baceous vines, and ordinary herbs. Among the trees the fol- 

 lowing are first-class forest trees, with trunks one to three feet 

 in diameter and fifty to a hundred feet tall. (Evergreens are 

 indicated by heavy type, as in the habitat lists.)
