IN the flowering of this plant, there are fome circumftances well deferving of attention. 



Two kinds of bloffoms are obfervable on it ; the one a very fmall fhort one, like the rudiments of a flower, a 

 little longer than the Calyx, with the mouth clofed, very hairy, and of a bright red colour ; the other a flower like 

 that of the Lamium purpureum, but much longer. 



The firft of theie blonoms, which fo far as refpecls the Corolla, are evidently imperfect, appear very early in 

 the Spring, in February and March ; the long and perfecl: blonoms do not make their appearance till May or June, 

 when they are obfervable on the tops of the flalks : and if the progrefs of the flowers be watched, the Corolla will 

 be found to be gradually -enlarged in different blonoms, till the weather being fufficiently warm, they come forth 

 fully formed. 



Thofe who have attended to the changes of Infects, muft have obferved, that if a Caterpillar has, previous to 

 its changing into the chryfalis or pupa ftate, been deprived of its proper quantity of food, the Fly has come forth 

 perfecl in all its parts except the wings, which are crumpled up, and never expand ; fo this plant, for want of 

 a fufncient degree of warmth, is not able to pufh forth an expanded Corolla ; yet being perfecl: in every other part, 

 the fpecies fuffers no diminution. 



I had for feveral years imagined, that the imperfecl: flowers were the rudiments of the long bloffoms ; but on a 

 more minute enquiry, I found that they never grew any longer, but decayed. I was then ready to fuppofe that 

 they were barren flowers ; but on differing them, I found that each had both Stamina and a Piftillum. 



Since the above obfervations were made, I find, on looking into the Flora Suecica, that Linnjeus takes notice of 

 its fcarce ever producing perfecl: bloflbms in Sweden. 



Here then is a procefs fomewhat fimilar to what we obferve in the Violet and fome other plants, where perfecl; 

 feed is produced, although the Corolla be not perfectly formed. 



It grows with us frequently on walls ; and in the greatefl abundance in the fields and gardens about Batierfiea and 

 Lambeth, where the foil is light.
