Botanical Notes. 



Sisynibriaiii Alliaria. — Among some plants sent by Miss 

 Alice Bovven from the vicinity of the Gomin Swamp, Quebec, 

 was a specimen of this European weed. Some years ago a large 

 patch of this plant was observed in the grounds of the Hon. G. 

 W. Allan, at Moss Park, Toronto. It is not a very valuable 

 acquisition to our Flora. The white flowers are small, and the 

 whole plant has a rather disagreeable alliaceous odour, from 

 which it takes its English name. Garlic White Cress. 



Cypripedium aristinum. — A splendid clump of this rare 

 Lady's slipper has been presented to the Botanic Garden of the 

 Central Experimental Farm by Mr. R. J. Drummond, of Perth. 

 This beautiful little Orchid is very rare. It has been found in 

 this vicinity in Dow's Swamp, at Alymer and at Buckingham. 



AretJiusa bulhosa. — A few specimens of this lovely Orchid 

 were found in full flower in the Mer Bleue by Mr. W. T. Macoun 

 on May the 28th. This is rather earlier than usual for the 

 flowers to be found. 



Listera australis. — The bed of this rare but not very showy 

 Orchid was visited on the above named date, and about a dozen 

 specimens were observed in full flower. • This locality is the only 

 one so far discovered for L. australis in Canada. There is no 

 doubt it is a very rare plant but it is probable that, on account 

 of its dull purplish brown colour, it has been overlooked by 

 collectors. 



Habenaria fivibriata, the Large Fringed Orchis. — From 

 time to time specimens of a Fringed Orchis are sent in for con- 

 firmation named as above, but in almost all instances the 

 specimens prove to be H. psycodes. If full data are kept there 

 is no difficulty in distinguishing between these two species. H- 

 fiinbriata is not only a larger and handsomer plant in all its
