. Mr. Bentham has long ago referred the Gardoguia Mexicana 
H. B.K. (G. betonicoides, Lindl., and Graham in Bot. Mag. t. 
3860), tothe genus Cedronella. The two genera are, however, in 
different sections of the Zabiate. From that species our present. 
one, detected by Mr. Charles Wright in an expedition from 
Western Texas to El Pasco, New Mexico, and no. 474 of that 
gentleman’s distributed collections, differs in the entirely 
glaucous stem and leaves, occasioned by a minute hoary pubes- 
cence, scarcely visible except in the recent plant, in the much 
smaller, more numerous, and shorter’ leaves, quite entire among 
and much below the whorls of flowers. Like that, however, 
the leaves abound in fragrant oil-dots. It flowers in the summer 
months, and makes a handsome appearance in the flower-border. 
Descr. Two and a half to three feet high, much branched, 
especially at the base: branches opposite, square, hoary with 
very minute pubescence. Leaves small and entire, hoary in the 
upper part of the stem and near-and about the flowers, and there 
numerous and approximate, ovate or ovato-lanceolate ; lower
