mere leaf variations in Habenaria orbiculata, H. obtusata, Orchis 

 spec tab His, etc., etc. 



There is a single specimen of Corallorhiza striata, Lindl., in the 

 herbarium of the University of Vermont, collected many years ago 

 by Joseph Torrey — date and locality not given, according to ancient 

 usage. The plant, however, is believed to have been collected near 

 Burlington. Prof. L. R. Jones writes me : "We shall have to await 

 its rediscovery before so crediting it in printed lists." I can but 

 acquiesce in this wise suggestion. 



Epipactis IFcllcboriiic, Crantz, was introduced in 1898, with some 

 garden plants from New York State, at Stockbridge, Mass. It was 

 hardly likely to persist, however, as it selected a hedge along the 

 main street for a habitat. 



Spiratithcs Romanzoffiana, Cham, is reported to me on good 

 authority as growing on Mt. Greylock, Massachusetts. As there is 

 no published record of the fact, and I am unable to obtain speci- 

 mens at present, I am obliged to omit it from my list until I can 

 record it without the possibility of a doubt. 



Orchis rotundifolia, Pursh, is accredited to Connecticut on the 

 authority of Robbins, who collected it at Norfolk (Bishop's List). 

 This report is very old and it may well be that the plant is now 

 extinct in this town, where it has not been seen for many years. 



I have been particularly impressed in the study of this interesting 

 order of plants by the fact that the tenure of life of many of our 

 rarer species of orchids is very insecure. It is evident that many of 

 them such as Pogonia affinis and pcndu/a, Tipularia discolor, Aplcc- 

 trum hicwa/c, Calypso borca/is, several Cypripediums, etc., survive in 

 some of the New England States only in the most secluded localities. 

 Even there they are doomed to early extinction in many instances, by 

 the growing demands for timber, by forest fires and by the clearing of 

 the land. 



Such plants as Hitchcock, Robbins, Tuckerman, and others 

 reported are seldom or never seen now in their former homes, but 

 must be sought for in the few localities, if there are any, which have 

 not yet been called upon to satisfy the insatiate maw of the pulp mill 

 or to suffer the withering influence of an increasing population.
