furrowed on their outer edges. Stigmata two, sessile, persisting, bilo- 

 bular, blunt, spreading. Germen obconical, almost entirely united to 

 the calyx, unilocular, bivalvular above, opening and spreading wide as 

 in M. trifida, so as to shew the green ovules long before they have at- 

 tained the full size. See<h dark brown, shining, crowded upon two pa- 

 rietal receptacles. 



The capsule in this genus is generally described as bivalvular, but certain- 

 ly in M. pentandra, M. trifida, and I believe in the other species, the 

 capsule is only bivalvular in the upper half!, the lower part forming an 

 entire cup. Linnseus, in the Genera Plantarum, calls the germen bifid, 

 but he afterwards adds, that the capsule is bivalvular. Nuttall says the 

 capsule is subsemibivalve. 



The present species was raised in the Botanic Gardens of Edinburgh and 

 Glasgow from seeds gathered by Mr Drummond in the Rocky Moun- 

 tains during the last expedition under the command of Captain Frank- 

 lin. The form and colour of its corolla is like M. nuda, but this (M. 

 nuda) is easily distinguished from our plant by its ten stamens, rather 

 longer filaments, procumbent stem, and rounder less acutely-jagged 

 leaves, and by the whole plant being smaller. 



"While this article was going to press, I received the number of the Bot. 

 Mag. for September, in which the plant is admirably figured ; and I readi- 

 ly adopt the specific name of my friend Dr Hooker, though equally ap- 

 plicable to M. trifida, to which indeed I was about to apply it when this 

 plant came into flower, and prevented me at the time from giving it to 

 either. M. pentandra flowered with us during June. I agree entirely 

 with Dr Hooker that this plant ought not to be separated from the ge- 

 nus Milella. Its habit and structure belong so exactly to that genus, 

 that the number of the parts, the chief particular in which they diffei", 

 could only form an artificial character, quite sufficient, however, to form 

 a pentandrous division of the species. 



Monarda menthaef'olia. 



M. menthcBfolia ; caule piloso ; foliis cordatis acuminatis, serratis, undi- 



que pilosis, breviter petiolatis ; floribus capitatis ; involucris herba- 



ceis venis purpureis. 



DESCttiPTiov Stem erect, tetragonous, purple, thickly covered with 



white pubescence. Leaves (1^ inch long, 10| lines broad) spreading, de- 

 cussating, on short petioles, cordate, acute, pale green, pubescent on 

 both sides, especially below, acutely serrated, strongly veined, the up- 

 ])ermost pair closely embracing the capitulum, and having immediately 

 within them four bracteae, two on each side, similar to themselves, but 

 rather softer, of paler green, with red veins ; within these, and surround- 

 ing the capitulum, are many unequal, subulate, ciliated, green bractete. 

 Flowers in a dense terminal capitulum. Calyx tubular, slightly curved, 

 nerved, smooth, except at the base of the teeth where there is a whorl 

 of spreading hairs ; teeth short, acute, equal. Corolla lilac ; tube cla- 

 vate, curved, very slender colourless and smooth at its origin, every 

 where else on the outside covered with short dense tomentum, smooth 

 within ; upper lip straight, subulate ; lower lip 3-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 ; antliers trans- 

 verse, flat, their upper edge deep purple, closely applied to each other, 

 and embracing the stigma ; filaments and style of the same colour with 

 the corolla. Stigma unequally bilobed. Germen 4. lobed, erect, yellow, 



small Perfume of the whole plant like mint. 



The species of Mtmarda are certainly in great confusion, and it is after 

 some hesitation that I have ventured to describe this as new, but I do 

 not find any described or in cultivation which I can believe to be the 

 same. It is nearly allied to M. oblungata, but is distinguisiied from it 

 by its much more hairy stem, its harsher and less acuminate leaves, and 

 shorter jietioles. It was raised in the Botanic Garden, and in the gar-
