Aviagallis caridea. 638 



*o 



at Little Calcott, near Shrewsbury, in which I did not per- 

 ceive any plants of G. Tetrahit, some seeds of G. versicolor, 

 which I sowed in four pots in sandy loam procured from a 

 depth of about 16 ft. from the surface. The soil was appa- 

 rently so pure, that no other plants came up besides those of 

 G. versicolor. The result of the experiment was, that in 

 pot No. 1. was one plant; in No. 2. thirteen plants; in No. 3. 

 one plant ; and in No. 4., in which no seeds had been sown, no 

 plant. These were carefully transplanted from the pots, and 

 properly marked, and all proved to be G. versicolor. The 

 transplanted plants were suffered to disperse their seeds, and 

 their progeny have ever since continued without the least 

 change to be G. versicolor. — W, A. Leighton. Shrewsbury,

[Galeopsis versicolor " is doubtless a distinct species, pro- 

 pagating itself by seed unaltered." (Smith, in his English 

 Flora, iii. 95, 96.) 



Benthain, in his Labiatarum Genera et Species, p. 524, 525., 

 deems G. versicolor Curt, a variety of G. Tetrahit L., and G. 

 pubescens Besser, which his synonyme shows is the same as 

 G. Walterzwa Schlect^ a variety too. He has made these re- 

 marks : — " I have much observed this plant [he means G. 

 Tetrahit L. as including all the forms that he deems to belong 

 to it] in Germany, where it is very common, and am fully 

 persuaded, with Fries [He has given in a note this extract 

 from Fries's " Nov. Fl. Suec. ed. 2d, 193." : — Corolla- mag- 

 nitudine inter Labiatas parum fido. Prsecipue Galeopsides hoc 

 respectu variant. Vidi G. Tetrahit floribus G. versicoloris, 

 et versa vice, et plene persuasu meo has plantas mere varietates 

 credas, recedentes circiter ut Viola tricolor et arvensis."], 

 that there is but one species. The size and colour of the 

 flowers are remarkably uncertain, and afford every shade of 

 difference from one extreme to the other ; and the difference in 

 pubescence between the G. pubescens and Tetrahit of German 

 authors, is but one of degree. It is but very seldom that a 

 pubescent specimen is to be found absolutely without the long 

 rigid hairs [His character of G. Tetrahit is " caule pilis rigidis 

 saepius hirto sub axillis tumido, foliis ovatis, calycibus glabris 

 hirsutisve"]; and, on the other hand, when these are most 

 abundant, they are almost always accompanied, especially in the 

 upper part of the plant, and on two opposite sides of the stem, 

 by a small quantity of the pubescence. The large variegated- 

 flowered specimens (G. versicolor of authors) have usually 

 less of this pubescence, and more of the hairs, than the smaller 

 red-flowered ones."]
