SALVIA DICHROA. 
Native of the Greater Atlas. 
Nat. Ord. Lasiara#.—Tribe Monarne&. 
Genus SALVIA, Linn. 3 (Benth. in DC. Prodr., vol. xii. p. 262). 
Satvia (Plethiosphace) dichroa; glanduloso-pubescens, caule erecto 4-gono 
angulis incrassatis pilosis, foliis sinuato-crenatis inferioribus petiolatis 
ovato-oblongis obtusis pilosis, caulinis sessilibus oblongis obtusis, 
supremis seu floralibus parvis ovatis acuminatis, racemis simplicibus, 
rachi robusto, verticillastris paucifloris, floribus pedicellatis, calycibus 
obovato-campanulatis glandulosis, labio superiore 3-dentato dente medio 
minore, inferiore 2-fido lobis triangulari-subulatis porrectis, corolla 
calyce triplo longiore, tubo glabro non inflato intus annulo piloso 
instructo, labio superiore elongato compresso obtuso pubescente inferiore 
superiori subequilongo 8-lobo, lobo intermedio suborbiculari pendulo 
albo, lateralibus decurvis brevibus, connectivis elongatis antice breviter 
porrectis apicibus tumidis, coherentibus. 
A near ally of Salvia bicolor, Desf. (Tab. nost. 1774) and 8S. 
alyeriensis, Desf., the former a native of Northern Marocco, 
and the latter of Algiers; but very distinct from both in 
the form of the leaves, and from the latter in the much. 
greater size of the lower lip, which, as in S. bicolor, nearly 
_ equals the upper. Of the two it is very much nearest to 
_ 8. bicolor, and but for the very different form of the radical 
leaves, and the nature of their lobing, I should have been 
_ disposed to regard it as a variety of that plant; the radical 
and lower leaves of S. dicolor are deeply cordate sinuate- 
toothed and much cut, the teeth and lobes spreading ; the 
_ analogous leaves on S. dichroa are oblong, acute at the base, 
_ and irregularly cut at the margin into large obtuse lobules. 
that point towards the apex of the leaf. In the description 
of §. bicolor under Tab. 1774, it is stated that the under-lip, 
Which at its first expansion is snow-white, almost immediately
