were in fruit, but flowering examples were obtained Tune 19, 

 1910. 



Genm vir ginianum L. Rough, or Virginian Avens. 



This is a coarse bristly plant with whitish flowers, a clump 

 of which was found in the upper part of the Beaver Meadow 

 July 9, 1908. It was also collected in a field below the Golf 

 Club on July 11, 1908. 



Trifolium arvense L. Rabbit-foot, or Stone Clover. 



This dull-foliaged plant, with silky flower heads looking 

 more like pussy-willow catkins than the honey-laden clover 

 blossoms that brighten and perfume our fields, is listed in the 

 Flora Ottawaensis as found in a field at Billings' Bridge, and it 

 is stated to be rare. The only locality which I have found for 

 it is a field of sandy gravelly soil adjoining the C.P.R. track 

 between Aylmer and the Park, where it was abundant August 

 2, 1909. 



Geranium Bicknellii Britton. Bicknell's Crane's-bill. 



Near Skead's Mills, September 2, 1905; Britannia, June 

 1, 1906, flowers; top of King's Mountain, August 1, 1909, fruit. 



Rhus canadensis Marsh. Fragrant Sumach. 



This shrub was originally collected near Tetreaultville, 

 P.Q., where all the individuals forming a considerable patch 

 were thought by Dr. Ami to be parts of the same plant, having 

 only staminate flowers and no seedlings. It also grows on the 

 top of King's Mt., the shrubs being younger than those at 

 Teatreaultville. Collected July 25 and August 1, 1909, and in 

 flower May 8, 1910. 



Elatine americana (Pursh.) Arn. Waterwort. Mud-purslane. 



This is a diminutive plant, almost microscopical in its 

 dimensions, which grows on the muddy margins of pools, etc. I 

 have specimens collected by Fletcher at Brigham's Creek, Hull, 

 in September, 1893. A good series was obtained, July 23, 1908, 

 at Cache Bay, near Hull, on the soft mud flats laid bare by the 

 unusually low water. The plants are firmly rooted and have to 

 be taken up with a knife and then have the adhering mud washed 

 off before they can be pressed. 



Panax quinquefolinm L. Ginseng. 



In the three localities mentioned in the Flora Ottawaensis 

 for this plant, to which the Chinese attach such an excessive 

 medicinal value, it is now extinct. The best locality was in 

 Powell's Grove, south of the railway track, about where Powell 

 Avenue is now, well toward the centre of the city. The plant 

 appears to be very rare and to occur only in the shade of rich 

 woods. A fine specimen with its striking bunch of bright red 

 fruit, was found in the wood north of Chelsea, September 18,
