SHORTER NOTES 

 Gymnadeniopsis nivea in Southern New Jersey. — While 

 botanizing near Bennett, Cape May Co., N. J., July 24, 1907, 

 in company with Mr. S. S. Van Pelt, I found a number of orchids 

 growing in a very wet bog. While these were as yet only in 

 early bud, I took them to be Gymnadeniopsis nivea on account of 

 the slenderness of the leaves and the appearance of the old flower 

 stalks, a few of which were still standing. Later trips to the spot 

 by Mr. Van Pelt and others proved the correctness of my identi- 

 fication, so that I am now able to add this interesting species to 

 the flora of New Jersey. On August 1 3 and September 4, it was 

 in full bloom and was found also in several adjoining bogs. 

 Another plant that occurred with it, unquestionably native, is 

 Boltonia asteroides, heretofore known only as an introduced 

 species in New Jersey.
