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

 but with long bracts, Rothrock. 



§ 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 reflexed bristly hairs, especially the anterior 

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

 Billardiera, Mcench. Shuttleworthia, Meissner. Uwarowia, Bunge. 



* Gland of the anthers small and short, sometimes inconsptcuous, on the middle of the back : 

 mainly librous-rooted perennials; but seedling^s 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, 6 to 12 lines 

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

 spikes short-peduncled or sessile, dense, at most oblong : fructiferous calyx oblong, 2^ or ■!! 

 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 ; Schauer in DC. Prodr.

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

 subterranean branches: leaves (14 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.

• 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. 176 ; L. f. Suppl.
