 Dr. Kellogg read the following descriptions : 



Audihertia Dorrii. — (Kellogg) Fig. 57. 



Stem suffi'uticose, branches opposite, spreading, hoary-pubes- 

 cent Avith minnte frosty villi, striate, terminated by ju-oliferous 

 or condensed whorls, whorls often remote or separated, of about 

 three or more. 



Leaves entire, the lower caullne obovate cmieately decurrent 

 into the short petioles (leaves about one inch in length, and one- 

 third in breath), obtuse or emarginate, whitish hoary on both sur- 

 faces with very minute villi, punctate with dark colored glands, 

 middle cauline more spatulate, lamina roundish, cuneately decur- 

 rent, the uppermost somewhat oblong, obtuse sub-sessile or sessile, 

 at length iDecoming l^ractoid at the terminal whorls, rounded and 

 obovate. 



Bracts persistent membranaceous, reticulate, three to five-nerved 

 roundish, (sometimes emarginate, rarely short cuspidate) smaller 

 forms varying to oblong, glabrous ^^•ithin, externally somewhat 

 strigose, margins ciliate, numerous, imbricated, covermg the calyx 

 purpleish, sessile or sub-sessile. 



Calyx campanulate with the upper lip truncate, subentire or 

 shortly tridentate, the middle tooth smaller, loAver lip two cleft, 

 toothed lobes lanceolate acute, points mucronate, margins ciliate ; 

 seeds naked, oval. 



Flowers purple, in whorls either separate and somewhat remote, 

 or condensed, as seen in the figure ; tube assert about as long again 

 as the calyx, slightly expanding, upper lip arched, tridentate, 

 lower hp three-lobed, lobes mostly lanceolate, spreading. Naked 

 within, minutely pubescent externally. Style exserted ; stigma une- 

 qually two-hpped, the subulate lobes glabrous, stamens exserted, con- 

 nective, continuous in the same direction with the connective, very 

 slightly produced backwards, and naked, point subulate. 



This plant is probably an Audibeiiia although the genus is 

 described as only " bifid" instead of trifid, as the upper lip is seen 

 to he in our specimens — the middle lobe of the lower lip also is 

 neither " very broad " nor " cmargmatc " ; the lobes also are 

 equal. 



It is certainly very closely allied to A. ineana ; but has the 

 upper lip of the calyx " entire," and lower lobes obtuse. The 

 racemes also are simple; these are often oppositely branched, and 

 he numerous flowers in remote whorls; calyx and bracts purple.
