Since the last of these papers was published a great many species have been added to the list of those known to occur in Canada ; the distribution of others has been greatly extended and a large number of notes worthy of publication have accumulated in our herbarium. Much of this material will be utilized in publi< cations which will be issued from this Department at an early date but it is hoped to print from time to time in The Ottawa Naturalist records that might not find a place elsewhere. Some of these records have appeared in other publications, but as these notes are intended primarily for Canadian workersnot allof whom have access to curretJt botanical literature, and in nearly every case new information as to distribution has been added, it has seemed best to make the record as complete as possible by includ- ing some matter that his been published elsewhere.

In A. cemuum the leaves are almost tlat and more or less keeled. \n A. recurvntum there is no keel and the channel is rounded as welt as the back.

A. recurvaium is common in the Rocky Mountains and British Columbia. Habbnaria macrophvlla, Goldie. This species is much rarer than //. orhiculata with which in recent years it has been contounded. //. orbiculala ranges from the Atlantic to the Pacific and north to Alaska.
