On the relations of certain fall to spring blossoming plants. 
AUG. F. FOERSTE. 
(WITH PLATES I AND It.) 
Most spring flowering plants in the more northern latitudes 
begin the development of their floral organs already during 
the previous year. The following table will give a very good 
idea of the extent to which this development has taken place 
in a series of plants collected near Clarendon, Vermont, du- 
ring the week from the twenty-second to the twenty-eighth 
of August. In this list are inserted two ett Cypripedium 
parvi forum Salisb. collected near Ludlow, Vermont, on the 
twenty-seventh of September, and Chimaphila maculata 
Pursh, found near Andover, New Jersey, on the ninth of Oc- 
tober. The first column indicates whether the scaly winter- 
buds are subterranean (S), subaerial, or chiefly covered with 
fallen forest leaves or surrounded by moss (SA), or aerial 
(A). The second column gives the regular flowering season. 
The third records the length (in millimeters) attained by the 
flower cluster at the dates when examined. In the case of 
Arisaema triphyllum Torr. the length of the spathes was given 
instead (S). The fourth column records the size of the largest 
flower bud in, these clusters. In two cases measurements 
were not recorded (d) ?
