224 The Ottawa Naturalist. 



Isopyrum is a genus of low perennials which is represented in the 

 province by one species /. biternatum, Torr. and Gray. Our only record 

 of it is from London where it was found by Mr. T. Dearness. In 

 general appearance it resembles Anemonella but the fruit is a two to 

 three seeded follicle, whereas in that genus it it is an achene. 



Gold-thread, (Goptis) is represented by one species C. Irifolia, 

 Salisb. which is found in cedar swamps and on hummocks in wet 

 woods throughout the province. The yellow rootstocks and white star- 

 like flowers amply distinguish it from all other swamp flowers. 



The Columbine [Aquilegia Canadensis, I..) is one of our lovely 

 spring flowers and is found in dry places amongst broken rocks in all 

 parts of the country. It is a curious circumstance that all the native 

 Columbines, and we have six, grow amongst the debris ot broken 

 rocks. 



No native species of Delphinium grows in the province but one. 

 D. Consolida L., the common Larkspur of the gardens is often found 

 by roadsides on waste-heaps or as a weed in gardens, and another 

 species less branching D. Ajacis has been found at Lake Scugog by 

 Mr. VV. Scott of the Normal School, Toronto. The pods are the best 

 character by which to separate them. In the first the follicle is smooth 

 and in the latter, pubescent. 



Black Snake Root or Black Cohosh, {Cimicifuga racemosa, Nutt.) 

 is a rare species and is only found in the southwestern part of the 

 province extending from Gait to the Niagara peninsula. It is a tall 

 plant with straight and stiff racemes of flowers often over a foot long. 

 We have nothing else like it and once seen, its general appearance will 

 not be forgotten. 



The Baneberry (Aclcea) has two representatives in our rich wood- 

 lands which are difficult to separate when in flower. These are A. 

 spicaia, L. var. rubra, Ait. and A. alba Mill. In general terms, one is 

 said to have red berries and the other white but this is not a fact as 

 each species has berries of both kinds. Both grow in damp woods in 

 rich soil and both have white flowers and very little difference in the 

 form of the raceme. In fruit, however, they differ widely no matter 

 what the colour of the berries, the pedicels in A. spicata
