DIDYNAMIA GYMNOSPERMIA. 



A natural order, consisting entirely of the Verticillatce of 

 Ray, and of Linnaeus, 42; theiai/a^i^of Jussieu, 39. See 

 Grammar 99. A few genera, comprised in Jussieu's first 

 section, are excluded from the present class and order of 

 the artificial system, as having only 2 stamens, and are 

 referred therefore to the second class, Diandria. Of 

 these the only British genera are Lycopus and Salvia. 

 See vol. i. 33 — 35. 



The following are the characters of the Verticillatce, a de- 

 nomination needlessly changed for Lahiatce. 



Flo'wers all complete, as well as perfect, having a calyx and 

 corolla, with stamens and pistil, in every individual. 



Calyx inferior, simple, of one leaf, erect, tubular, often tu- 

 mid at the base, on the upper or lower side, permanent ; 

 orifice more or less deeply divided into 5 unequal, often 

 pointed, spreading segments. 



Corolla of 1 petal, erect, tubular, and containing honey, at 

 the base, without any particular apparatus ot a nectary ; 

 limb almost invariably ringent, or lipped ; ujjper lip either 

 upright, or vaulted, rarely very short, or deeply divided ;
