Galeopsis. LABIATE. 79 



22. GALEOPSIS. Linn. ; Benth. Lab. p. 522. hempnettle. 



[ From the Greek, galeos, a weasel, and opsis, appearance ; the flowers having some resemblance to the head of that 



animal.] 



Calyx tubular-campanulate, about 5-nerved, 5-toothed ; the teeth with spine-like tips, nearly 

 equal, or the upper ones longer. Corolla 2-lipped ; the throat dilated : upper lip ovate, 

 entire, arched ; the lower spreading, 3-lobed : lateral lobes ovate ; lower one obcordate, or 

 somewhat 2-cleft : the palate with two teeth on the upper side. Stamens 4, ascending ; 

 the lower pair longer : anther-cells opposite, transversely 2-valved ; inner valve of each 

 cell hispidly ciliate , the outer valve naked. — Annual herbs, with the whorls several- or 

 many-flowered. Flowers red, yellowish or variegated. 



1. Galeopsis Tetrahit, Linn. Common Hemp-nettle. 



Stem hispid, swollen below the joints ; leaves ovate, hairy on the upper surface. — Linn, 

 sp. 2. p. 579 ; Benth. Lab. p. 524. 



var. 1. parviflora, Benth. : corolla \\ - 3 times the length of the calyx. Benth. I. c. G. 

 Tetrahit, Engl. bot. t. 207 ; Pursh, fl. 2. p. 407 ; Bigel fl. Bost. p. 236 ; Torr. compend. 

 p. 234 ; Beck, bot. p. 277. 



var. 2. grandiflora, Benth. : corolla 3-4 times as long as the calyx. Benth. 1. c. G. 

 versicolor, Curt. fl. Lond. 2. ic. ; Engl. bot. t. 667. G. Ladanum, Bigel. I. c. ? 



Stem 1-2 feet high, covered with stiff retrorse hairs, more or less branching, erect ; the 

 branches thickened just below the joints. Leaves 2-4 inches long and 1-2 inches wide, 

 thin, rather coarsely serrate, often unequal at the base, slightly pubescent underneath ; the 

 upper surface clothed with scattered appressed hairs : petiole an inch or more in length. 

 Whorls approximated towards the summit of the stem and branches. Teeth of the calyx 

 spreading, usually longer than the tube, hispid, and terminating in a long spinescent point. 

 Corolla in var. 1. about twice the length of the calyx, purplish or sometimes pale ; in var. 2. 

 yellow with a large purple spot on the lower lip, more than twice as large as in the other 

 variety. 



Old fields, road-sides, etc. : the first variety very common north and west of Albany ; the 

 large-flowered form only in the northern counties. The latter is what I called (without suf- 

 ficient examination) G. Ladanum, in my Catalogue of New-York plants in 1844. 



23. STACHYS. Linn. ; Benth. Lab. p. 525. hedge-nettle. 



[ So named from the Greek, stachys, a spike ; in allusion to its mode of flowering.] 



Calyx tubular-campanulate, 5 - 10-nerved, somewhat equally 5-toothed, or indistinctly 2- 

 lipped. Corolla 2-lipped ; the upper lip erect or somewhat spreading, often arched, entire
