LABIATiE. 345 



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

 straii^ht or falcate, usiiully concave ; tiie lower spreading, its middle lobe often emar- 

 ginate. Stamens inserted in tiic 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 wliicli is polliiiifercnis but unlike the upper one. Nutlets conmionly developing 

 mucilage and long spiricles when wetted. 



29. AUDIBERTIA. Corolla with upi)er lip spreading, 2-lobcd or emarginate; lower 

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

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

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

 sometimes obliquely projects into a subulate i)oint, but never bears even a trace of an 

 anther-cell. Otherwise as Salvia, 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. 



* * vVnther with both cells fertile and similar, contiguous and divaricate, more or less 

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

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

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

 emarginate ; the lower spreading, ^j-lobed, its middle lobe retuse or emarginate : stamens 

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

 the upper lip: calyx tubular, b'iJ-lo-nerved : inflorescence verticillastrate-capitate, 

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

 lanceolate to setaceous. 



30. MONARDA. Calyx elongated-tubular, hiostly 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. Caly.x shorter, naked in the throat, bilabiate; upper lip 3- and the 

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

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



Tribe V. NEPETE/E. Stamens 4, both pairs fertile; the ^w.sYer/o/- (inner or upper) 

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

 the ujiper 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, e.xserted; the upper pair usually 

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

 oblique, 5-tootheil. 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 fiattish erect upper one 

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

 2-lobed. 



* * Antiiers 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-tootlied. ('orolla witli tube narrow at base ; throat dilated ; ujjper lip somewhat con- 

 cave, emarginate or 2-lol)ed ; lower sjjreading, with middle lobe large. 



35. DRACOCEPHALUM. Calyx equal at the throat, S-tootluMr; the upper tooth (at 

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

 Corolla, &c., of Nepelu. 



Tnii5E Vr. SCUTELLARINE.E, Visiani. Stamens 4, ascending and parallel; both 

 pairs fertile; the 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 tin; style very short or none. Ovule 

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

 or tnberculate: seed transverse. Embryo oirved; the .short radicle incumbent on 

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