288 SCROPHULARIACE^E. Veronica. 



-t Capsule ovate, elliptical, or oblong, merely emarginate : stems erect from a slender creeping 

 rootstock : leaves all sessile or nearly so : corolla blue or violet. 



V. Cusickii. A palm high, glabrous or pubescent: leaves ovate or oblong, entire (half to 

 three fourths inch long) ; the pairs crowded up to the naked peduncle of the 3-9-flowered 

 raceme : pedicels slender, often as long as the flower and longer than the oblong-linear 

 bracts : corolla 4 or 5 lines in diameter, with ample rounded lobes : these surpassed by the 

 filiform filaments and style; the latter thrice the length of the deflorate calyx. Alpine 

 region of the Blue Mountains, W. Oregon, W. C. Cusick, a form with glabrous thickish 

 leaves. Scott Mountains in N. California, at 8,000 feet, E. L. Greene, form with narrower 

 and hirsute-pubescent leaves, rarely with a denticulation or two. Nearly related to 1". 

 macrostemon of Bunge. 



V. Stelleri, Pall. A palm high, hirsute, leafy up to the sessile corymbose raceme : 

 leaves ovate, copiously crenate-serrate (three fourths inch long) : pedicels slender, longer 

 than the flowers : corolla as in the foregoing : stamens barely equalling its lobes : slender 

 style not surpassing the calyx: "capsule ovate, hardly emarginate." Rcem. & Sch. Syst. 

 Mant. i. 102; Cham, in Linn. ii. 557; Benth. in DC. Prodr. x. 481. Unalaska and other 

 Aleutian Islands. (Kamtschatka and Curile Islands.) 



V. alpina, L. A span or rarely a foot high, hirsute-pubescent or glabrate : leaves mostly 

 shorter than the internodes of the simple stem, ovate to oblong, crenulate-serrate or entire 

 (half to full inch long): raceme spiciform or subcapitate, dense, or interrupted below: 

 pedicels erect, shorter than the calyx (at least in flower), much shorter than the bracts : 

 corolla with comparatively small limb, 2 or 3 lines in diameter, surpassing the stamens and 

 short style: capsule elliptical-obovate, emarginate. Fl. Lapp. 7, t. 9, fig. 4; Spec. i. 11 ;

 i. 101 (villous inflorescence) ; Hook. Bot. Mag. t. 2975 (as var. of alpina), the larger-leaved 

 and villous-pubescent form, commonest in N. America. V. nutans, Bong. Veg. Sitk. 39. 

 Alpine regions, White Mountains of New Hampshire, Rocky Mountains and Sierra Nevada 

 for nearly their whole length, and north to Labrador, subarctic regions, and Aleutian 

 Islands. (Eu., Asia, Greenland.) 



-i -i Capsule oblately orbicular and obcordate : lower leaves short-petioled ; upper sessile: corolla 

 usually bluish or pale with blue stripes. 



V. serpylli folia, L. Glabrous or puberulent : stems creeping and branching at base, 

 with flowering summit ascending 3 to 9 inches high : leaves oval or roundish, entire or 

 crenulate (half inch or less long) ; the upper passing into bracts of the leafy spiciform 

 raceme: pedicels erect, as long as the calyx. Fl. Dan. t. 492 ; Engl. Bot. t. 1075. 

 Open and grassy grounds. Labrador to the mountains of Georgia, New Mexico, and 

 across the continent to California and Aleutian Islands. (Eu., Asia, S. Am.) 



* * Low annuals : flowers in the axils of ordinary or of the upper more or less reduced and com- 

 monlv alternate leaves: corolla mostly shorter than the calvx. (All but the lirst naturalized 

 from the Old World.) 



-I -1 Seeds flat or flattish, small and numerous: flowers very short-pedicelled, appearing some- 

 what spicate, the floral leaves being reduced or unlike the others. 



V. peregrina, L. (NECKWEED.) Glabrous, or above minutely pubescent or glandular : 

 stem and branches erect, a span or two high : leaves thickish ; lowest petioled and oblong 

 or oval, dentate; the others sessile, from oblong to linear-spatulate, mostly alternate; 

 uppermost more bractlike and entire : capsule orbicular and slightly obcordate. V. Muri- 

 limclica, Murr. Comm. Goett. 1782, 11, t. 3, not L. V. Caroliniana, Walt. Car. 61. V. X<il<t- 

 ]>ensis, HBK. Low grounds, and a weed in damp cultivated soil, throughout the U. S. and 

 Canada to Brit. Columbia. (S. Am., and now almost cosmopolite.) 



V. ARVENSIS, L. Pubescent, a span or two high, soon spreading: lower leaves ovate, cre- 

 nate, short-petioled: floral sessile, lanceolate, entire: capsule broadly obcordate. Cult, 

 and waste ground, Atlantic States to Texas : rather rare. (Nat. from Eu.) 



4_ -l_ Seeds fewer, cyathiform, much hollowed on the ventral face ( OmpJialospora, Bess.): pros- 

 trate or spreading annuals : flowers on slender at length recurving pedicels from the axils of 

 ordinaiy and petioled leaves. 



V. AGRESTIS, L. Pubescent : leaves from round-ovate or subcordate to oblong, crenate-ser- 

 rate, about equalling the pedicels : sepals oblong, surpassing the small corolla : ovules 

 numerous: capsule orbicular with a deep and narrow emargination, maturing few or soli- 

 tary seeds. Sandy fields, New Brunswick to Louisiana : rare. (Nat. from Eu.)
