108 DIDYNAMIA— GYMNOSPERMIA. Thymus. 



hairs ; the margin in 5 erect, broadish, nearly equal, coloured 

 teeth. 



The calyx differs remarkably in different species of this genus, con- 

 sisting in some of an undivided unilateral leaf, without teeth ; 

 while in others it is, more or less equally, five-toothed, or two- 

 lipped. The involucrum is uniform and constant in all. 



O. Onites of Dillenius in Ray's Synopsis, not that of Linnaeus, ap- 

 pears to have been some variety of the vulgare, which no person 

 has been able to ascertain since the time of Mr. Dale.
