xxx THE CAYUGA FLORA. 



cular species was given in Dr. Alex. Thompson's " List of Plants found 

 in vicinity of Aurora" published in the Regents' Report for 1841. A cer- 

 tain number are rejected from that list as they were known not to 

 have become really established. Another set inadvertently omitted 

 in printing are given below, and should have the star in the text. 

 These are : 



Caltha palustris, Asclepias tuberosa. 



Rubus strigosus, Gerardia flava, 



" occidentalis, " quercifolia, 



" villosus, Phryma Leptostachya, 



" Canadensis, Solanum Dulcamara, 



Pirus Americana (introd.) Rumex acetosella, 



Anthemis Cotula. Phytolacca decandra. 



Tanacetum vulgare, 



13. In the expressions indicating rarity or abundance of a species, 

 the word "rare" signifies that there are from one to four stations, 

 and the specimens few in each. The other terms are applied with 

 as much care as conld be exercised, in the following order referring to 

 their comparative abundance : scarce ; infrequent or uncommon ; not 

 uncommon ; frequent ; abundant ; common. 



14. Certain names of localities will strike many as unfamiliar. Old 

 names have in several instances been revived, as in the case of the 

 traditional Indian name — Neguaena — for that portion of the so-called 

 Inlet above its junction with Six Mile Cr. Eagle Hill was the old 

 name for what is often called "Bald Hill, Ithaca." But as there is 

 another Bald Hill in Caroline, a revival of the old name seemed de- 

 sirable. Since the opening of the University other names have been 

 invented and adopted to meet the needs of collectors, and these are, 

 of course, retained on the map and elsewhere. 



The Disappearance of Species. 



Certain species once known to exist within our limits have appa- 

 rently disappeared. We do not find Rhe.via, Hippuris, Castilleia or 

 Pogonia pendula ; some of them may yet reappear, but probably not 

 in the stations first reported. This catalogue reveals to all botanical 

 students the stations of many rare plants, not before generally known. 

 It is true that no student of our department, after he has come to have 

 a real appreciation of his work, has ever needed the caution, to treat 

 every plant as rare until it is known to be abundant, therefore, even 

 this gentle reminder of a very good rule may not, perhaps, be strictly 

 necessary. It may not, however, be out of place to point out the de- 

 sirability of applying this rule to the plants of Cascadilla Woods, in 

 particular. On account of its convenience to our laboratories, as 

 well as its remarkable variety of forms, it is of almost priceless value, 

 not only for its flowers, but the mosses and fungi it shelters. It is 

 hoped, therefore, that not only will students be reasonably careful in 

 collecting in it, but that all interested in the future of our campus 

 will use every means to preserve the woods and its many interesting 

 plants from any injury whatever.
