A FORM OF LINARIA VULGARIS. 



In the summer of 1910, in the neighbourhood of Toronto, I 

 discovered a form of Linaria vulgaris that seems to be very 

 unusual, at least I have met with no one who has seen it and so 

 far I have not heard of any one who has found this form. The 

 corolla is perfectly white and completely spurless. So far as I 

 have yet discovered, the plant does not set seed. 



The calyx seems to have undergone no change, but the 

 corolla is regular. Its two-lipped appearance is wanting and 

 the lobes of the gamopetalous corolla are nearly equal in size. 

 The four stamens and the pistil seem to be' perfect, yet so far 

 I have failed to find a perfect capsule with seeds. The plant must 

 spread by its underground runners. 



My attention was first drawn to the plant by its whiteness. 

 At first I supposed I had found a plant unknown to me, but on 

 closer examination I came to the conclusion that it was a form 

 of Linaria vulgaris. I was soon confirmed in this belief by 

 finding another patch of it in which some of the plants had the 

 white spurless corollas and the ordinary form of the corolla on 

 the same stalk, the white regular form being always below the 

 spurred form. It seems to be well established, for in 1911, and 

 this summer, the variety is as abundant as ever. There are 

 a number of patches of this peculiar form extending through 

 fields and along the road for a quarter of a mile. The patch first 

 discovered had only the variety growing in it and was at least 

 20 feet long by 4 feet wide and it had hundreds of plants growing 

 in it.

The above form is of much interest owing to the fact that 

 it represents a spurless type of that monstrosity generally known 

 as Peloria. This variation, which is merely an aberrant form 

 of no systematic value whatever, is characterized, as is well 

 known, by the presence of five spurs in the corolla. These 

 Peloria types are merely accidental. They are to be found 

 especially in autumn on specimens which had been mowed or 

 pastured during the summer and, as a rule, they occur in the 

 same head as tvpical irregular flowers.
