sixth line), indicates a feeble representation ; the blank means that the 

 order is not indigenous to that flora. Thus, the second, third, and fourth 

 orders are not represented, so far as we know, in the Eocky Mountain and 

 the Pacific floras, *. e., they do not extend westward beyond the Atlantic 

 forest region. The next line declares that the order Berberidacece is, 

 considering the size of the order (in this instance small), richly repre- 

 sented in the Atlantic flora, sparingly in that of the Eocky Mountains 

 (inclusive of the plains on the east and the desert basin on the west), 

 more numerously in that of the Pacific district. Nymphccacecc are in the 

 same case, having very full generic representation in the Atlantic flora 

 but hardly any in that of the Eocky Mountains, and a little more on the 

 Pacific side of the continent. Sarraceniacece take full capitals in the first 

 column, not that the species or types are numerous, but because the 

 few and remarkable Sarracenias represent the whole order, excepting 

 two species 5 one of them is in California, and the Pacific column is en- 

 tered accordingly. Such a presentation is only approximate, but in a 

 general way it tells the story.
