the development of the leaf and flower buds, more especially 

 the latter. This experience seems to be in accord with that of 

 Prof. Oakes Ames, jii(l}j;inj; from his paper, "The Mycorrhiza of 

 Goodyera Pubescens," Rhodora, Vol. 24, March 1922, pp. 37-46, 

 in which he refers to his studies of colonies of Goodyera (now 

 Epipactis) pubescens, which colonies he says are the result of 

 seeds falling near mature plants, where mycorrhizal fungi are 

 generally most in evidence, and where they germinate readily. 

 Seeds which drift away on air currents or are blown abroad by 

 the wind and fall where there is no nidus of the necessary fungus, 

 fail to germinate. Otherwise, how account for the colony form- 

 ing tendency of the species and the peculiarities of distribution. 



Before closing, it may not perhaps be out of place to mention, 

 that in the latest book on Orchids, "Enumeration of the Orchids 

 of United States and Canada," by Prof. Oakes Ames, April 23, 

 1924, it will be noticed that in the Key to the genera. Calypso 

 is placed among the species that have a simple rhizome. Writing 

 to me on the subject July 2, 1924, Prof. Oakes Ames says, "I 

 think this is right for the ordinary run of specimens one finds. 

 The coralloid character to which you have drawn attention 

 seems to be rare. Your notes had not come to my attention in 

 time to make a straddle." Whilst agreeing to this in the main, 

 I might say, that my further studies of Calypso incline me to 

 the belief that this coralloid character is not so rare as at first 

 surmised, especially where the plants are found growing on 

 dead logs, stumps, or small branches of trees which are in a 

 state of decay, as I have previously pointed out in the "Journal 

 of the New York Botanical Garden," vol. 25, 1924, p. 28. The 

 photographs from which the plate has been made were taken by 

 the Geological Survey at Ottawa, and I am again indebted to 

 Dr. M. O. Make for them.

An Additional Anychia from Pennsylvania. — In the early 

 part of the past century Rafinesque described a half-dozen 

 species of Anychia. Specimens of these species, distributed by 

 Rafinesque himself, and now extant, show that they represent 

 either Anychia canadensis or A. dichotoma. Recently specimens 

 of a plant novelty have come to hand. They represent a species
