a much lower altitude, and the Taconic range of moun- 

 tains bringing in southern and western forms, has the 

 larger flora ; here belong Asplenium ebenoides, Pteris 

 aquilina pseudocaudata, W Oodwardia Virginica, Pelloca 

 atro purpurea, and Asplenium Ruta-muraria, with the 

 exception of the Willoughby station of the latter two. 

 Eastern Vermont has Botrychium Lunaria and Nephro- 

 d iu m simulatum, but such forms as Botrychium lanceo- 

 latum, Camptosorus, Phegopteris hexagonoptera, and 

 Woodsia obtusa are very uncommon, and found only at 

 low altitudes in the lower Connecticut valley. 



The State presents four sharp areas, (i) Western 

 Vermont, a lowland region, including the Champlain 

 valley and its lower tributaries and those of the Hudson 

 River, in southern Vermont. The finest fern localities 

 of this region are the limestone cliffs and river gorges. 

 Here grow Pellcca atro purpurea, Asplenium ebeneum, 

 A. ebenoides, A. trichomanes, A. Ruta-muraria, Camp- 

 tosorus, Woodsia obtusa, Pelloca gracilis, Cystopteris 

 bulbifera, etc. 



(2) The lowlands of the lower Connecticut valley, 

 with traces of limestone in places, producing a fine flora. 



(3) The Green Mountain region. In this I include 

 the country above one thousand feet, or at least two- 

 thirds of the State. This region has only about one-half 

 of the species, but here belong Polystichum Braunii, 

 Nephrodium spinulosum dilatatum, and Phegopteris 

 polypodioides. 



(4) The alpine and sub-alpine cliffs, and with them 

 the deep river gorge, Quechee Gulf. These produce 

 Asplenium viride, Woodsia glabella, Woodsia alpina, and 

 Nephrodium fragrans. 



Within a few years our State has been very closely 

 searched for ferns. This movement was begun by C. G. 

 Pringle, his work being particularly strong on the alpine 

 forms, and to Pres. Ezra Brainerd we owe much of our 

 knowledge of Botrychium. 



There has been much rivalry in several localities,
