ceeding tlio flowers, the uppermost ovate-lanceolate and only equalling them: corolla 

 bluish (about 2 lines long): nutlets with a narrower almost smooth commissure. HBK.

Var. Neo-Mexicana. Stems rather strict and slender : leaves bipinnately cleft or 

 almost parted: bracts not longer than the calyx. V. officinalls, var. hirsuta, Torr. Bot. 

 Mex. Bound. 28. Borders of thickets near theCoppermines, New Mexico, Writjld, Bydow. 

 Appears as if a hybrid between V. canescens and V. officinalis. S. Arizona, similar in foliage 

 but with long bracts, Rotltrock. 



2. Flowers more showy, at first depressed-capitate, becoming spicate in fruit : 

 anthers of the longer stamens appendaged by a gland on the connective : tube of 

 corolla at the upper part lined with refiexed bristly hairs, especially the anterior 

 side : anther-cells slightly oblique or unequal. Glandularia, Gmelin, Nutt. 

 Billardiera, Mcench. Shuttleworthia, Meissner. Uivaroivia, Bunge. 



* Gland of the anthers small and short, sometimes inconspicuous, on the middle of (lie back: 

 mainly fibrous-rooted perennials; but seedlings flowering as annuals: nutlets reticulate-rugulose, 

 mostly scabrous on the commissure. Species difficult to distinguish, apparently passing into 

 each other. 



V. ciliata, Benth. Low or depressed, hirsute-pubescent or hispid, 3 to 10 inches high, 

 diffusely spreading from an apparently annual root; the branches not creeping nor rooting 

 at base : leaves once or twice 3-cleft or parted and variously incisely lobed, to 12 lines 

 long, with cnneatc base contracted into a margined petiole ; lobes from linear to oblong : 

 spikes short-peduncled or sessile, dense, at most oblong: fructiferous calyx oblong. 2A or 3 

 lines long, with short subulate teeth : limb of the purple or bluish corolla 2 to 4 lines 

 broad: gland of the anthers usually very small. PI. Hartw. 21 ; Schaucr in DC. Prodr. 

 xi. 553 ; Gray, Bot. Calif, i. 008. Dry plains, W. Texas to Arizona and the southern 

 border of California. (Mex.) 



V. bipinnatifida, Nutt. A span to a foot high, hispid-hirsute, perennial, rooting from 

 subterranean branches : leaves (H to 4 inches long), bipinnately parted, or 3-parted into 

 more or less bipinnatifid divisions ; the lobes commonly linear or rather broader : spikes 

 in age elongated, bracts setaceous-attenuate, mostly surpassing the calyx: teeth of the 

 latter slender, subulate-setaceous from a broader base, unequal : limb of the bluish-pur- 

 ple or lilac corolla 4 or 5 lines broad; lobes obcordate: nutlets at maturity usually 

 retrorsely muriculate-scabrous or hispidulous on the commissure. Jour. Acad. Philad. ii. 

 123; Torr. in Ann. Lye. N. Y. ii. 233; Schauer in DC. 1. c. 553. Glandularia bipinnatifida, 

 Nutt. in Trans. Am. Phil. Soc. n. ser. v. 184. Plains and prairies, Arkansas and Texas to 

 the base of the Rocky Mountains in Colorado, &c. Cult, as "V. nionlana." 



V". Aubletia, L. A foot or less high, branching and ascending from a creeping or root- 

 ing base, perennial (as rightly said by Jacquin), slender, soft-pubescent, hirsute, or gla- 

 brate : leaves (1 or 2 inches long) ovate or ovate-oblong in outline, with truncate or broadly 

 cuneate base tapering into a margined petiole, incisely lobed and toothed, often more deeply 

 3-cleft: spikes pedunculate, elongated in fruit: bracts subulate or linear-attenuate, shorter 

 than or equalling the similar slender and unequal teeth of the narrow calyx : limb of the 

 reddish-purple or lilac (rarely white) corolla half or two-thirds inch broad: commissure of 

 the nutlets minutely white-dotted or nearly smooth. Jacq. Vind. ii. 82, 1. 170; L. f. Suppl.

 t. 2200; Schauer, 1. c. ; form with narrower and more incised leaves. V. Lambert!, var. 

 rosea, Don, Brit Fl. Card. ser. 2, t. 303, with large and light-colored corolla (three-fourths 

 inch wide, fragrant). Open woods and prairies, Florida to Illinois, Arkansas, and New 

 Mexico. (Mex.) Cult., variously mixed. 



* * Gland of the anthers oval, as high and almost as large as one of the cells: stem erect from an 

 annual root. 



V. Wrightii. Hispidulous-pubescent : stem simple below, 2 feet high : leaves pinnately 

 3-7-parted or deeply cleft, contracted at base into a margined petiole; lobes mostly lan-
