346 LABIATE. 



36. SCUTELLARIA. Calyx in antliesis campanulate, gibbous, with a crest-like or 

 casque-siiaped projection (answering to the upper sepal) on the back, closed after the 

 corolla falls, not inflated, at maturity of the fruit splitting to tlie base ; upper part not 

 rarely falling away ; the lower persistent. Corolla with long exserted tube, naked within ; 

 its anterior lobe or lower lip with the sides recurved. Anthers ciliate-pilose. Nutlets very 

 rarely wing-margined. 



37. SALIZARIA. Calyx globular or at first oblong, barely repand-bilabiate, not appen- 

 daged or gibbous on tlie back, much enlarged after antliesis, becoming vesicular-inflated 

 and reticulated. Nutlets depressed, tuberculate-roughened, marginless. Corolla, &.c., of 

 Scuk'/lariu. 



Tribk VII. STACHYDEzE, Benth. (Lab., with part of Scutellar'mece.) Stamens 4; 

 both pairs fertile, i^arallel and ascending under tlie concave and commonly galeate 

 upper lip of tlie bilabiate corolla (or in Murrubium included in the throat) ; the an- 

 terior (lower or outer) pair longer (except in a Phlomis) : anthers 2-celled or con- 

 fluently somewhat 1-celled. Calyx 5-10-iierved, or veiny. Bitter-aromatic or with 

 hardly aromatic herbage. 



* Calyx reticulate-veiny, membranaceous or chartaceous, more or less inflated, deeply 

 bilabiate ; the lips flattened and closed in fruit ; upper lip plane and broad : corolla 

 with inflated throat from a more or less exserted tube. 



38. BRUNELLA. Calyx oblong, somewhat 10 nerved ; upper lip truncate, 3-toothed, its 

 teeth very broad and short ; lower 2-cleft, its teeth lanceolate. Corolla with assurgent 

 tube, ringcnt lips, and slightly contracted orifice ; upper lip galeate, entire ; lower o-lobed ; 

 its middle lobe dependent, rounded, concave, denticulate. Filaments, at least of the upper 

 pair, 2-toothcd at the apex, one tooth naked, the other bearing the 2-celled anther, the 

 cells of which are divaricate. Nutlets smooth and glabrous. Inflorescence verticillas- 

 tratc-capitate or spicate. 



39. BRAZORIA. Calyx short-campanulatc, indistinctly nerved, mostly declined in fruit ; 

 both lips broad ; the upper M-lobed and somewhat recurved; the lower 2-lobcd and sur- 

 rected in fruit. Corolla with inflated throat, broad and barely concave upper lip, and 

 spreading o-lobcd lower one ; its lobes short and roundish. Filaments simple : anthers with 

 somewhat divergent cells. Nutlets smooth, glabrous or pubescent. Inflorescence race- 

 mose-spicate. 



* * Calyx more or less membranaceous and inflated or enlarged after flowering, obscurely 

 nerved, but somewhat veiny, o-5-lobed, not bilabiate, ojjen : corolla showy ; throat in- 

 flated ; upper lip more or less concave, not galeate : filaments more or less villous. 



40. PHYSOSTEGIA. Calyx nearly regular, and equally 5-tootlied ; the tube campanu- 

 late or oblong, hardly nerved or veineil, moderately turgid in fruit. Corolla gradually 

 inflated upward ; lips short ; the upper erect, rounded, entire ; lower somewliat spreading, 

 8-parted, its roundish middle lobe emarginate. Antliers uniform ; the cells nearly parallel, 

 denticulate or slightly spinulose along the edges of the valves. Style almost equally 

 2-cleft at apex. Nutlets triquetrous, smooth and even. Flowers simply opposite in the 

 spikes, one under each bract. 



41. MACBRIDEA. Calyx tubular campanulate or funnelform, O-lobcd ; upper lobe nar- 

 rower, oblong, entire, obtuse; the two others broad (each of two combined sepals) and 

 2-lobed or entire. Corolla mucii inflated above, ratlier deeply bilabiate; upper lip round- 

 ish and fornicate, entire or nearly so; lower spreading, with o roundish lobes, middle one 

 larger. Anthers unconnected, hairy on the face ; cell.s divergent. Style equally 2-toothed 

 at apex. Nutlets oblong, nervose. Inflorescence terminal and capitate, 2 or o flowers 

 under each bract. 



42. SYNANDRA. Calyx campanulate, inflated, membranaceous, deeply 4-cleft ; the lobes 

 lanceolate-subulate, somewliat equal; the 2 lower slightly smaller, the fifth or uppermost 

 wanting. Corolla with narrow tube, inflated above into a very ventricose throat ; upper 

 lip somewhat fornicate, entire ; lower widely spreading, .>lobed, the middle lobe emar- 

 ginate. Filaments very villous above : anthers nearly glabrous ; the cells divergent, the 

 contiguous ones of the \\]')]>vr stamens sterile and connate! Up])er fork of the style very 

 short. Nutlets smooth, ovate-compressed, with lateral angles almost winged. Inflores- 

 cence simply and loosely leafy-spicate. 



* * # Calyx of flrmer texture, distinctly 5-10-nerved or striate, 5-10-toothcd. 

 ••— Stamens included in the short tube of the corolla, the upper lip of which is merely 

 concave. 

 ■43. MARRUBIUM. Calyx tubular-cylindraceous, strongly ribbed, and with 5 or 10 sub- 

 ulate or spinulose teeth. Tube of co'rolla included in the calyx ; lips short ; the upper
