Uinhellifera> : have for the most part white tlowers, next 

 those of a yellow or green color. 



Ler/uininosce : the tlowers are recognized at once as highly 

 modified and specialized, with buttertly shaped cor- 

 ollas mainly, yet upon an enumeration of the species 

 in London's Encyclopedia there were found to be 

 548 yellow s})ecies to 372 of all other hues put to- 

 gether ! 



Lentibulariaceoe : Utricularia, largely yellow. 



Violariaceoi : violets, about as many yellows as white or 

 violet, there being two yellow flowered s[)ecies in 

 Massachusetts. 



Liliacem: Aloe, all colors, yet forty-three out of ninety-

Alistnacece: has Butonius and Alisnia lose colored, Sagit-

Naiadacece: ranking lowest of all, Apo)ioyeto)i^ no petals,

We are ()l)liged to omit many other Orders for want of
