easily bring one face to face with important and unsuspected discoveries. 
The time was not ripe for the full appreciation of what those acute 
inquirers had under their eyes. That required a grasp of the theory 
of symbiosis which had not arrived. 
It is a curious circumstance that on the Continent the battle of 
priority has already been fought over Monotropci Hypopitys. Woronin 
in 1885 (Bericht. d. D. Bot. Gesellsch. iii. 206) says : ‘ Alle Prioritats- 
rechte in der Frage “ uber die auf Wurzelsymbiose beruhende 
Ernahrung gewisser Baume durcfi unterirdische Pilze ” miissen 
demnach nicht Herrn B. Frank, sondern Herrn Fr. Kamienski 
zugeschrieben werden/ 
Kamienski in fact describes the mycelial investment of the roots of 
Monotropa in the Botanische Zeitung for 1881 (p. 459). But his 
fullest account was given in the following year in a paper, Les organes 
vegetatifs du Monotropa Hypopitys , &c., published in the M^moires de 
la Soci&e Nationale des Sciences Naturelles et Mathem. de Cherbourg, 
t. xxiv. He says : — ‘ Toutes les parties les plus actives de la racine . . . 
sont recouvertes d’une couche epaisse et dense d’un mycelium qui ne 
permet pas aux racines d’avoir un contact direct avec le sol/ 
After minutely describing the mycelium, he proceeds: — ‘ Cette 
relation Strange entre le champignon et le Monotropa n’est pas un fait 
unique et isol£ dans la nature. Nous pouvons le ranger avec d’autres 
faits semblables auxquels M. de Bary a donne la denomination de 
symbiose/ 
Drude in 1873 appears also to have observed mycelium in the 
roots of Monotropa , and to have thought it identical with that first 
observed long ago by Schleiden in Neottia. But I have not had the 
opportunity of consulting his paper.

Postscript. — Since the above was in type, I have found that the 
English authors whom 1 cite are mentioned in the very complete 
bibliography of Mycorhiza given by Sarauw in the Botanisk Tidsskrift, 
Vol. xviii, p. 247, 1892-3: I am indebted to Mr. Percy Groom for 
the reference to this paper.
