FERNALD. — MEXICAN SALVIAS. 491 



ful status ai-e here noted, although they are so incompletely character- 

 ized as to make their identification without access to the types quite 

 impossible. In such cases the traditional conception of the plant has 

 been maintained as far as possible, though it is highly probable that 

 future study of these little-known types will identify some of them with 

 better known species. 



The descriptions of two species recently published from old manu- 

 scripts contain so little of specific significance that it is impossible to 

 say upon what plants they were based. These are S. azurea and S. 

 dichroma, La Llave in La Naturaleza, vii (1885) Apend. 82. 



A European species, S. Sclarea, L., is often cultivated in central 

 Mexico and is sometimes distributed in exsiccatae as if an indigenous 

 plant (for example, see SchafFher's no. 49 from the mountains of San 

 Luis Potosi). 



In the study of species of § Membranaceae Mr. N. E. Brown of the 

 Royal Gardens at Kew has rendered very valuable service by comparing 

 specimens submitted to him with the types of Bentham's species. 



SYNOPSIS OF SPECIES. 



(As far as possible the sectional numbers and descriptions have been 

 maintained as given in the Prodromus.) 



Section VII. CALOSPIIACE, Benth. Calyx ovate, tubulose or 

 campanulate, the upper lip entire or shortly tridentate, the teeth approxi- 

 mate, and the middle one longest. Corolla-tube exserted or included, 

 not annulate within, but occasionally furnished with 2 teeth near the 

 base. Upper lip (galea) straight or concave, entire or often short- 

 emarginate; the lower with spreading lobes. Anterior portion of the 

 connective deflexed, linear, longitudinally connate or approximate, oc- 

 casionally a little dilated, and rarely bearing an empty adnate anther-cell. 



§ 1. Micranthae, Benth. Bracts small, mostly deciduous. Corolla 

 blue or white, short, 8 mm. or less (in one species nearly 1 cm.) in 

 length, very slightly or rarely almost twice exceeding the calyx; the 

 tube generally ventricose ; the galea straight. 



# Corolla very small, 3 to 5 mm. long : calyx glandular. 

 +- Calyx-lobes blunt.
