South Hill. — Besides the number of interesting though scattered species in the 

 general region of South Hill, there is a particularly interesting colony of rare plants 

 in or near South Hill Marsh. Some of these plants suggest the light-acid-soil floras 

 of the Coastal Plain and the Southern States, and the woodland about the marsh has 

 much the appearance of the scrub-oak barrens of eastern Massachusetts. The reason 

 for this affinity is not clear. The soil is chestnut and noncalcareous. The following 

 unusual plants are found on South Hill : 



Car ex hirta (north slope) 



Carex incomperta 



Carex glaucodea 



Carex folliculata 



Juncus marginatum 



Habenaria flava, var. virescens 



Rosa setigera (north slope) 



Aronia arbutifolia, var. atropurpurea 



Amelanchier intermedia 



Prunus susquehanae 



Linum virginianum 



Viola sagittata, var. ovata 



Lyonia ligustrina 



Onosmodium hispidissimum (north 

 slope) 



Veronica Anagallis-aquatica. var. lati- 

 folia (north slope) 



Houstonia caerulea 



Antennaria occidentalis 



Antennaria Parlinii 



Ravines.- — The most characteristic topographical peculiarity of the Cayuga Lake 

 Basin is the extensive ravine formation. Botanically the ravines are very interesting, 

 and they furnish a large number of plants not generally found elsewhere. Of these. 

 Draba arabisans, Saxifraga aizoides, Primula mistassinica, and Pinguicula vulgaris, 

 are noted as relics of the postglacial migration and are now known elsewhere in New 

 York State only in very isolated localities, though they are frequent In high northern! 

 latitudes. The more important unusual plants are as follows :
