408 PROCEEDINGS OF THE AMERICAN ACADEMY 



canescently pubescent on both sides. — Hills near Zacatecas, Pringle, 

 239. Some of Parry and Palmer's 739 come very near to it, and 

 have hirsute pubescence on the branchlets. 



Var. WiSLiZENi is more herbaceous and greener, merely puberulent, 

 but the calyx-nerves are more obviously hispidulous, the small leaves 

 less crenulate and not rugulose. — Sierra Madre west of Chihuahua, 

 Wislizenus, 152. Not far south of this, i. e. 150 miles north of Bato- 

 pilas, Palmer, 379. 



Salvia lycigides. Cabsplaee, frutescens, viridis, sub lente mi- 

 nutissime j^uberula ; ramis gracilibus elongatis foliosis ; foliis parvis 

 (raajoribus semipoUicaribus) angusto-oblongis obtusis integerrimis raro 

 paucidenticulatis basi contracta subpetiolatis, venis obscuris, floralibus 

 minimis caducis ; verticillastris 2-4-floris ; corolla semipollicari creru- 

 lea calyce triple longiore sub fauce ventricosa glabra, labio postico 

 oblongo apice puberulo, antico parum longiore rotundato trilobo. — 

 Santa Eulalia Mountains, near the city of Chihuahua, Pringle, 52. I 

 know no species with which this may be particularly compared. The 

 foliage might be likened to that of a Lycium ; whence the name. 



Salvia albiflora, Mart. & Gal., at least the plant so named in 

 Mex. Bound. Survey, from the INIexioan border. Shady ravines near 

 Batopilas, Palmer, 154. Forma c^rulescens, with "corolla light 

 blue, often almost white when in shade," Palmer, 96; also "bright 

 blue in shady ravines," Palmer, 157. Since Linden records the color 

 of the corolla in his specimens as pale blue, we may safely refer all of 

 Palmer's to one species. Seemaun's plant referred to S.Jlexuosa differs 

 only in a slightly larger calyx. 



Salvia Palmeri. Herbacea^, suborgyalis, S. polystachyce peraffi- 

 nis, thyrso pariter contracto densifloro ; foliis ovatis rarius subcordatis 

 tantum serrulatis baud rugoso-venosis supra viridibus fere glabris sub- 

 tus incanis ; stylo nudo vel paroe pilosulo. — Hillsides at the Frailes, 

 on the mountains above Batopilas ; blue-flowered, Palmer, 259. The 

 difference in hue between the two faces of the leaf is striking, espe- 

 cially in the younger leaves ; the whiteness of the lower face, unlike 

 that of S. polystachya, is from a pubescence too minute and close to be 

 distinguished into separate hairs, even with a lens, and is persistent. 



Cedronella micrantha, Gray. About 150 miles north of Ba- 

 topilas, Palmer, 420, with the same minute corollas before known. 



Cedronella aurantiaca. Puberulo-incana ; foliis deltoideo- 

 lanceolatis vel subhastatis subcrenatis (1-2-pollicaribus cum petiolo 

 ^-pollicari) supra viridibus subtus canis ; thyrso superne nudo laxi- 

 floro ; calyce canrpanulato fere herhaceo (lin. 2 longo), dentihus deltoi-
