MINT FAMILY. 245 



20. MELISSA. Calyx with 3-tootlied upper lip flat. Corolla more or less curved 



and ascending. Filaments arching and bringing the anthers together in pairs. 

 Otherwise as in 19. 



§ 5. Stamens only 2, parallel and ascending under the erect or somewhat scythe- 

 shct/jed entire or bartly notched upper lip of the.^ corolla : anthers 1-celled, 

 either strictly so or by confluence of the 2 cells end to end. 



21. SALVIA. Calyx 2-lipped, the upper lip 3-toothed or entire, the lower 2-cleft, 



tliroat not hairy. Corolla deeply 2-lipped ; the lower lip spreading or hanging, 

 3-Iobed, the middle lobe larger and sometimes notched at the end. Filament 

 as it were compound, the proper filament short and bearing on its apex an 

 elongated thread-like or linear body (the connective, in fact) attached by its 

 middle, one end of which ascending under the upper lip bears a linear 

 1-celled anther, the other descending bears the other smaller and imperfect 

 cell, or a mere vestige of it, or is naked. Flowers usually large or showy. 



22. ROSJIARINUS. Calyx and corolla nearly as in Salvia, but the lateral lobes of 



the lower lip of the corolla erect and somewhat contorted (as in some Sages 

 also). Stamens resembling those of Monarda and protruded, but with a short 

 tooth on the filament below the middle. Shrub. 



23. MONARU A. Calyx tubular, elongated, many-nerved, nearly equally 5-toothed, 



mostly hairy in the throat. Corolla deeply 2-lipped, narrow in the throat, 

 the oblong or linear lips about equal in length, the lower 3-lobed at the apex, 

 its narrower middle lobe slightly notched. Stamens with long and simple 

 filament bearing directly on its apex a linear anther. Flowers rather large, 

 numerous hi the whorled or terminal heads. 



24. BLEPHILIA. Calyx short-tubular, naked in the throat, 2-lipped, the upper 



lip with 3 awned, the lower with 2 nearly blunt teeth. Corolla with a more 

 expanded throat, bluish. Otherwise like Monarda, but flowers smaller. 



§ 6. Stamens 4, diverging or ascending : the upper or inner pair longer ! Upper 

 lip of the corolla erect or a little arching, the lower spreading. 



25. LOPHANTHUS. Calyx rather unequally S-toothed. Upper lip of corolla 



slightly 2-lobed, the lower moderately spreading, its middle lobe somewhat 

 crenate. Stamens not parallel, the lower and shorter ones more or less as- 

 cending, the upper and longer ones diverging and declining, so as to seem the 

 lower. Tall erect herbs, with small flowers clustered in panicled spikes. 



26. NEPETA. Calyx obliquely 5-toothed. Stamens parallel and ascending, and 



their anthers approaching in pairs under the upper lip of the corolla, their 

 cells diverging from each other. Middle lobe of lower lip of corolla con- 

 siderablv largest. 



27. CKDRONkLLA. Flowers nearly like those of Nepeta: but the cells of the 



anthers parallel. 

 37. PHLOMIS, of the next section, might from the stamens be sought for here. 



§ 7. Stamens 4, (he lower or outer pair longer, ascending and parallel, their anthers 

 in pairs mostly under the concave or arched upper lip of the corolla. Planti 

 not sweet-scented, some of them bitter-aromatic. 



* Corolla inflated funnel-form and rather slightly 2-lipped: calyx ihinnish, open 

 bell-shaped in fruit, the 5 teeth equal and pointless : flowers simply spiked, 

 oidy one to each brad or floral leaf. 



28. PHYSOSTEGIA. Upper lip of the corolla broad and a little arched, entire; 



lower of 3 broad and somewhat spreading short lobes. Smooth and scentless 

 herbs, with thickish and sessile lanceolate or oblong leaves. 

 * * Corolla decidedly 2-lipped : calyx also 2-lipped, irregular, closed in fruit. • 



29. BRUNELLA. Calyx tubidar bell-shaped, reticulated, flattened on the up- 



per side; the upper lip broad, flat, 3-toothed; the lower 2-cleft. Tube of 

 the corolla dilated on the lower side just below the rather narrowed throat; 

 ujiper lip arched and entire; lower widely spreading, with lateral lobes ob- 

 long, the concave middle one rounded and crennlate. Filaments 2-tootlied at 

 the apex, the lower tooth bearing the anther. Flowers in a terminal close 

 head or short spike. 



30. SCUTELLARIA. Calyx short, with the very short lips truncate and entire, and 



a lar^e hump on tlie upper side, the whole'helmet-shaped; the upper lip usu- 

 ally falling away when the fruit is ripe. Corolla with rather long ascending 

 tube, the later.ai lobes of the lower lip small and somewhat connected with 

 the arched upper lip, tlie middle lobe larger and spreading or the sides reflcxed : 

 anthers of the lower stamens 1-celled. Bitterish herbs, not aromatic, with 

 flowers single in the axil of each bract or leaf.
