teeth, where there is a whorl of spreading hairs: teeth 
short, acute, equal. Corolla lilac: tube clavate, curved, 
very slender, colourless, and smooth at its origin, every- 
where else on the outside covered with short, dense tomen- 
tum, smooth within; upper lip straight, subulate, lower 
lip three-lobed, the central lobe the longest, linear, narrow, 
inflected, and cleft, the two lateral rounded, with erect 
edges, Stamens as long as the style, smooth; anthers 
transverse, flat, their upper edge deep purple, closely applied 
to each other, and embracing the stigma ; filaments and 
. style of the same color with the corolla. Stigma unequally 
bilobed. Germen four-lobed, erect, yellow, small. Per- 
fume of the whole plant resembling Mint. 
The species of Monarpa are certainly in great confusion, 
and it is not without some hesitation that I have ventured 
to describe this as new ; though there is none described, or 
in cultivation, which I can satisfy myself as being the same: 
It is nearly allied to M. oblongata, but is distinguished from 
it by the much more hairy stem, the harsher and less acu- 
minated leaves, and shorter petioles. It was raised in the 
Edinburgh Botanic Garden, and in the garden of Mr. 
Nett, of Canonmills, from seeds collected by Mr. Drum- 
mMonD, between. Norway House and Canada, and flowered 
freely in August. When very luxuriant in cultivation, the: 
stem is ascending and less hairy, and very rarely it is con- 
tinued through the capitulum. Even the native specimens 
vary in the degree of hairiness and the number and depth of 
the serratures mm the leaves, which also differ in their breadth 
at the base, and are more or less elongated. The appear- 
ance of the less vigorous cultivated plants exactl y resem- 
bles the few which are in Mr. Drummonp’s Herbarium.
