THE CAYUGA FLORA. xvii 



character from the Ithaca region. They are in reality very large 

 springs from which are always pouring large brooks of cold water. 

 Their united waters flow north to the Clyde River. Beyond a sandy 

 ridge and a few rods south of the ponds, is a Tamarack swamp extend- 

 ing to the Pout Pond, the outlet of which is Black Brook flowing south 

 into the Seneca River, west of Waterloo. These are, therefore, water- 

 shed marshes and ponds half-way between the Ca)-uga and the Clyde 

 River water-systems. The following plants are found in the marshes 

 about these several ponds, — excepting the last eight, which occur in 

 damp sandy soil not far away, — and have not been observed in the 

 Cayuga Flora proper : 

 Drosera intermedia, var. Ameri- Scleria verticillata. 



cana. Carex Buxbaumii. 



Valeriana sylvatica. ' " chorhdorhiza. 



Solidago Ohioensis. " decomposita. 



" neglecta, var. linoides. " disticha. 



Utricularia cornuta. Tephrosia Virginiana. 



Gentiana linearis. Baptisia tinctoria. 



Bartonia tenella. Kalmia angustifolia. 



Habeuaria blephariglottis. Pj-cnanthemum lanceolatum. 



' ' ciliaris. Cyperus filiculmis. 



Triglochin palustre. Carex monile. 



Scheuchzeria palustris. Panicum microcarpum. 



Rhynchospora capillacea. Dicentra eximia? 



Gerardia purpurea, Gentiana crinita, Thuja, Habenaria tridenta- 

 ta, Arethusa, Eleocharis rostellata, Cladium, Carex alata, Corydalis 

 glauca, Galium pilosuni, Andromeda ligustrina, Myrica cerifera, 

 although elsewhere in our limits, are rare, and are inhabitants of West 

 Junius. The ponds and their marshes where occur this odd combina- 

 tion of Atlantic coast and northern species, are like a little section 

 from Bergen Swamp, Genesee Co. Considering their very limited 

 area they contain as interesting a flora as any other region in our state. 



The Affinities of the Cayuga Flora. 



Without doubt it is closely allied to the plants of that vast area in- 

 cluding the Ohio valley, the Great Lakes and a part of Canada. Our 

 territory of course, skirts the southern or southeastern side of this, 

 just where it sweeps round toward its northern terminus. The num- 

 ber of species which find their eastern or southeastern or southern 

 limit with us will furnish something of a test of our relation to that 

 region. After a careful review it is found that at least fifteen species 

 having a western and southwestern distribution find their limit with- 

 in our territorj-. Among these are Jeffersonia, Gymnocladus, Solida- 

 go Ohioensis, Carya sulcata. That some of these are found farther 

 east, as 'near Oneida L., does not interfere with the general truth 

 stated, viz., that they do not pass beyond usmto Susquehanna basin so 

 far as known. There are thirteen species having a decidedly north- 

 western, northern or northeastern range which have their southern 

 terminus here.
