ENGLISH BOTANY. 



ORDER LIIL— LABIATE. 



Ilei-bs, undershruljs, or, more rarely, shrubs with the stem, or at 

 least the branches, 4-6idecl. Leaves always opposite, generally fragrant, 

 from containing essential oil; without stipules. Flowers perfect, ir- 

 regulai*, generally in small subsossile cymes in the axils of the upper 

 leaves or bracts ; the flowers of these cymes apparently meeting round 

 the stem and forming false whorls or verticillasters ; sometimes forming 

 a raceme or spike-like raceme ; rarely only a single flower is produced 

 in the axils of each bract or leaf, so that they are in pairs at each 

 node. Calyx 5-toothed ; the teeth sometimes so combined that it 

 becomes bilaliiate, and sometimes even with apparently only 2 teeth 

 or lobes. Corolla hypogynous, tubular, with an irregular limb, usually 

 bilabiate and ringent. Stamens 4, didynamous, more rarely 2, mserted 

 in the tube of the corolla. Ovary of 2 carpels, each so deeply divided 

 that the ovary is 4-celled and 4-lobed, with a single style coming from 

 the centre of the 4 lobes, and consequently apparently from the base 

 of the carpels ; stigma more or less 2-lobed ; ovules 4, 1 in each cell or 

 lobe of the ovary. Fruit of 4 separate indehiscent cocca usually called 

 nucules^ each enclosing a single erect seed. Embryo almost always 

 straight ; albumen none, or in very small quantity and fleshy. 



Tribe I.— MENTHOIDE^. 



Coi'olla funnel-shaped, scarcely bilabiate. Stamens 4, rarely 2, 

 divergent, nearly equal ; anthers 2-celled, cells contiguous. 



GENUSJ.—'LYCOWS. Linn. 



[^ Calyx regular, 5-toothed, teeth flat. Corolla funnel-shaped, nearly 



^ regular, 4 -lobed ; upper lobe generally notched. Fertile stamens 2; 



the upper or inner pair sterile, or absent ; anther-cells parallel, or 



\ ultimately divergent. Nucules truncate at the apex, surrounded by 



2 a corky border at the base.
