PYCNANTHEMUM. 



P. Californicum, Torr, is Koellia Californica in Bay-Reg. Bot. Whitish with 

 soft hairs: leaves ovate or narrower, sessile: flowers white. 



MICROMERIA. 



M. purpurea, Gr. Greene thinks this is the common garden pennyroyal (Mentha 

 pulegium, L.), but the description of the former in the Synoptical Flora of North 

 America does not fit the latter plant. 



MELISSA, Tourn. 



M. officinalis, L. , Common Balm, may be found outside of gardens occasionally. Its 

 lemon-like odor distinguishes it from other mints. 



AUDIBERTIA and SAL VIA. 



These genera are joined under the latter name in Bay-Reg. Bot., and a species of the 

 former (A. polystachia) is the basis of a new genus Ramona, Greene, to which is 

 also added A. humilis, which is the species described in Bay-Reg. Bot. 



NEPETA, Linn. 



N. cataria, L. (Catnip) and N. Glechoma, Benth, (Ground Ivy) are found occasion- 

 ally. The former is erect, 2 feet high or more, somewhat hoary with minute downy 

 hairs; the leave petiolate, ovate-cordate, coarsely toothed; the small flowers in short. 

 dense spikes: calyx downy, 1-5 ribbed, teeth nearly equal; corolla bluish or nearly white; 

 the upper pair of stamens projecting above the lower pair. The latter is a creeping 

 plant with orbicular-reniform, crenate leaves; the blue flowers 9 lines long, usually six 

 in a whorl in the axils of leaves on short, ascending branches. 



LAMIUM, Tourn. 



L. amplexicaule, L., is another European herb fairly established in San Jose and 

 some other localities. Stems weak, leaves distant, the lower petioled, the upper sessile 

 or clasping, crenately lobed and incised: slender purple corolla with spotted lower lip: 

 anthers hairy. 



STACHYS. 



S. velutina, Greene. Stout, 2-6 feet high, soft-hairy: leaves rugose, short-petioled, 

 cor date -ovate, 3-6 inches long: calyx-teeth spreading, corolla small, white with red 

 dots and lines; upper lip deeply concave concealing the stamens. Too near S. albens. 



S. stricta, Greene. More slender than the last and smaller, less hairy, resinous- 

 glandular: leaves narrower and thinner: corolla white, the upper lip sub-orbicular,
