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

§ 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. — Glandidaria, Gmelin, Nutt. 

 Billardiera, Moench. Shuttleworthia, Meissner. Uwarowia, Bunge. 



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

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

 mostly scabrous on the commissure. Sjiecies difficult to distinguish, a])parently 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-clef t 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, 21 or 3 

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

 broad: gland of the anthers usually very small. — PI. Hartw. 21; Schauer in YiC Prodr. 

 xi. 553; Gray, Bot. Calif, i. 608. — 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 (1^ to 4 inches long), bipinnately parted, or 3-parted into 

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

 in age elongated . bracts setaceous-attenuate, mostly surjiassing the calyx . teeth of the 

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

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

 retrorsely muriculate-scabrous or hispidulous on tlie 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, liirsute, or gla- 

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

 cuneate base tiipering into a margined petiole, incisely lobed and toothed, often more deeplj^ 

 3-cleft: spikes pedunculate, elongated in fruit: bracts subulate or lineai'-attcnuate, shorter 

 than or equalling the similar slender and unequal teetli 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.
