stidi Mbnnieria simillimus ;" but the flowers arc much larger 

 and handsomer. We have hitherto kept it in the greenhouse, 

 where it flowers copiously; but in all probability a common 

 frame would suffice for its winter protection, and the open air 

 in summer. 



Descr. Herbaceous, perennial, branching copiously from a 

 central root, everywhere prostrate and rooting, quite glabrous 

 and subsucculent ; branches four-angled. Leaves opposite, ses- 

 sile, varying from orbicular to oblong, quite entire in our plant 

 at the margin, one-nerved (no evident lateral veins). Peduncles 

 longer than the leaves, opposite, axillary, solitary, one-flowered. 

 Calyx rather small in proportion to the size of the corolla, sub- 

 campanulate, five-angled, five-toothed; teeth short, erect, with a 

 rounded, short, crenate lobe between the teeth. Corolla rather 

 bright lilac, paler on the lower lip, dotted with deep yellow iu 

 the faux (and there bigibbous and pubescent); tube iufmidihuli- 

 form, longer than the calyx ; limb very large and spreading, two- 

 lipped, upper two-, lower lip- threc-lobed ; lodes large obtuse, or 

 refuse. Stamens and style included. Ovary ovate. Style filiform. 

 Stigma two-lipped.
