LABIATE. 345 



28. SALVIA. Corolla with upper lip erect (entire, emarginate, or rarely 2-lobecl above), 

 straight or falcate, usually concave ; the lower spreading, its middle lobe often emar- 

 ginate. Stamens inserted in the throat of the corolla : connective commonly linear or fili- 

 form, transverse on the short (sometimes very short) and mostly horizontal filament, its 

 descending or porrect portion continued beyond the articulation and either more or less 

 dilated and naked, or bearing an abortive rudiment of the second anther-cell, or some- 

 times one which is polliniferous but unlike the upper one. Nutlets commonly developing 

 mucilage and long spiricles when wetted. 



29. AUDIBERTIA. Corolla with upper lip spreading, 2-lobecl or emarginate ; lower 

 spreading and 3-lobed, the middle lobe broad and emarginate. Filaments slender, exserted, 

 seemingly simple and bearing a linear one-celled anther, or with an articulation, showing 

 that the portion above the joint answers to a filiform connective, the lower end of which 

 sometimes obliquely projects into a subulate point, but never bears even a trace of an 

 anther-cell. Otherwise as Sale/a, but the calyx (always naked in the throat) more deeply 

 cleft in front, or oblique, or as it were spathaceous. Nutlets smooth, unchanged when 

 wetted. 



* * Anther with both cells fertile and similar, contiguous and divaricate, more or loss 

 connate or confluent at their junction, so as to become or to imitate a single linear 

 cell, on a very small and inconspicuous dorsal connective : corolla with slender tube, 

 and lips of somewhat equal length ; the upper erect, linear or oblong, entire or barely 

 emarginate ; the lower spreading, 3-lobed, its middle lobe ret use or emarginate : stamens 

 inserted in the throat of the corolla, ascending, usually more or less projecting from 

 the upper lip: calyx tubular, 13-15-nervcd : inflorescence verticillastrate-capitate, 

 dense, many-flowered, multi-bracteate : outer bracts and bractlets broad ; inner from 

 lanceolate to setaceous. 



30. MONARDA. Calyx elongated-tubular, mostly 15-nerved, regular or nearly so, almost 

 equally 5-toothed, more or less villous-bearded or hirsute at the orifice. Corolla narrow 

 or dilated at the throat ; middle lobe of lower lip larger or longer than the lateral. 



31. BLEPHILIA. Calyx shorter, naked in the throat, bilabiate; upper lip 3- and the 

 shorter lower one 2-toothed ; teeth aristiform or subulate. Corolla dilated at the throat; 

 lower lip broader ; its linear-oblong middle narrower than the roundish lateral lobes. 



TRIBE V. NEPETEJE. Stamens 4, both pairs fertile; the posterior (inner or upper) 



pair surpassing the anterior. Corolla distinctly bilabiate. Calyx usually 15-nerved; 

 the upper teeth or lip commonly larger or longer. 



* Anthers separated or distant (not approximate in pairs) ; their cells parallel or nearly so. 



32. LOPHANTHUS. Stamens divergent or distant, exserted; the upper pair usually 

 declined; the lower or shorter pair ascending. Calyx tubular-campanulate, more or less 

 oblique, 5-toothed. Corolla with tube not exceeding the calyx ; upper lip nearly erect, 

 2-lobed at the apex ; lower spreading, its broad middle lobe crenate. 



33. CEDRONELLA. Stamens parallel, ascending. Calyx campanulate or short-tubular, 

 5-toothed, the throat little oblique. Corolla with short 'lips; the flattish erect upper one 

 2-lobed ; middle lobe of lower lip largest, commonly crenulate-erose and more or less 

 2-lobed. 



* * Anthers more or less approximate in pairs ; their cells divaricate or divergent : fila- 

 ments ascending, not exserted. 



34. NEPETA. Calyx more or less oblique at the throat, equally (or somewhat unequally) 

 5-toothed. Corolla with tube narrow at base; throat dilated ; upper lip somewhat con- 

 cave, emarginate or 2-lobecl ; lower spreading, with middle lobe large. 



35. DRACOCEPHALUM. Calyx equal at the throat, 5-toothed ; the upper tooth (at 

 least in ours) very much larger than the others, sometimes the 3 upper partly united. 

 Corolla, &c., of Ncpeta. 



TRIHK VI. SCUTELLARINE/E, Visiani. Stamens 4, ascending and parallel; both 

 pairs fertile; tha anterior (lower or out:-r) pair longer and with anthers mostly one- 

 celled by abortion (the other cell rudimentary or wanting); those of the posterior 

 pair 2-celled. Corolla bilabiate; but with the small lateral lobes more connected 

 with the galeate upper lip; lower lip therefore of a single lobe. Calyx bilabiate, 

 closed in fruit; the lips entire. Upper fork of the style very short or none. Ovule 

 campylotropous or amphitropous. Nutlets depressed or globular, rough-granulate 

 or tuberculate: seed transverse. Embryo curved; the short radicle incumbent on 

 one of the cotyledons! Herbage bitterish, little or not at all aromatic.
