13. PHYSOSTEGIA, Benth. FALSE DRAGON-HEAD. 



Almost glabrous herbs : with lanceolate and cal lose -denticulate or serrate 

 leaves; the upper ones sessile, lowest tapering into a petiole, floral reduced 

 to bracts of the simple or panicled spikes. Flowers cataleptic (remaining in 

 whatever position they may be turned). Corolla showy rose or flesh-color, 

 often variegated. 



1. P. parviflora, Nutt. Stems rather slender, leafy, a foot or two high : 

 leaves lanceolate or ovate-lanceolate, denticulate : spikes short, 1 to 4 inches 

 long : calyx short-cam panulate, inflated-globular in fruit and with short 

 mostly obtuse teeth : corolla inch long. Saskatchewan and Wyoming to 

 Oregon and British Columbia. 



14. STACHYS, Tourn. WOUNDWORT. 



Flowers verticillastrate-capitate or clustered, or sometimes few or solitary 

 in the axils of the floral leaves, forming usually an interrupted spicate inflo- 

 rescence. In ours the corolla is purple or rose-red, not over inch long ; the 

 tube not exceeding the calyx-teeth. 



1. S. palustris, L. From densely soft-pubescent to roughish-hirsute, 

 leafy : stem 1 to 3 feet high, hirsute or hispid : leaves ovate-lanceolate, cre- 

 nate-serrate, Ik to 3 inches long, sessile or nearly so by a broad or subcordate 

 base, sometimes almost velvety-tomentose beneath : clusters of the spike 

 mostly approximate, 6 to 10-flowered. Across the continent. 



ORDER 61. PLANT ACIIVACE^E. (PLANTAIN FAMILY.) 



Chiefly acaulescent herbs with one to several-ribbed or nerved radical 

 leaves, simply spicate inflorescence, and regular 4-merous flowers, and 

 the corolla scarious and veinless. 



1. PLANTAGO, Tourn. PLANTAIN. RIBWORT. 



Flowers perfect or polygamo-dicecious, each subtended by a bract : corolla 

 salverform with a short tube, or nearly rotate : stamens 4 or sometimes 2, on 

 the tube of the corolla : ovary 2-celled, with one or more ovules in each cell : 

 capsule circumscissile toward the base : scape from the axils of the radical 

 leaves, mostly bearing a single simple spike or head of greenish or whitish 

 small flowers. 

 * Stamens 4 : flowers all perfect : corolla remaining expanded, never closed over 



the fruit. 



- Leaves 3 to 8-nerved or ribbed, varying from glabrous to pubescent, from lanceo- 

 late to almost rotund.* 



1. P. major, L. Leaves ovate or oval, rarely subcordate, several-ribbed: 

 spike commonly dense, obtuse at apex : sepals rotund-ovate or obovate ; the 



1 The introduced P. lanceolata, L. , may be known by its oblong-lanceolate 3 to 5-ribbed 

 leaves, tapering into a slender petiole, usually much shorter than the slender and angled
