Cal. inferior, of 2 opposite, erect, acute, small, membra- 

 nous, deciduous leaves. Cor. oblong, tubular, ringent, 

 with a prominent palate, closing the mouth : pet. t, more 

 or less combined ; dipper Up flat, obtuse, notched, re- 

 flexed ; its base prominent, obtuse, constituting the nec- 

 tary ; laxver lip like the upper, sometimes with a similar 

 pi'ominent nectary^ sometimes only keeled, at the base ; 

 2 interior petals alternate with the 2 lips, linear-oblong, 

 slightly connected by their callous tips. Filam. 2, awl- 

 shaped, flat, shorter than the corolla, 1 within each lij). 

 Anth. roundish, 3 terminating each filament. Germ, su- 

 perior, roundish or oblong, compressed, pointed. Style 

 terminal, short. Stigma compressed, of 2 flat lobes. 

 Pod roundish or oblong, of 1 cell, with 1 or many po- 

 lished, crested seeds. 

 M. DeCandolle remarks that each prominence, at the base 

 of the corolla, contains a nectariferous gland ; and that 

 each of the lateral anthers has but one cell, there being 

 therefore only 8 cells, or, properly speaking, 4 anthers in 

 all. But it is easier to understand them as 2 double- 

 celled, and 4 single-celled, anthers. 

 'VUe. plants are h.erbaceous, smooth, brittle, with annual or 

 perennial roots, in the latter case sometimes tuberous. 

 Stems simple or branched, mostly angular. Leases stalk- 

 ed, variously compound. Fl. clustered, with partial 

 bracteas. Cor. purple, red, yellow, or white, often partly 

 green. Seed-vessels very various, insomuch that many 

 bc^tanists, in former times as well as in our days, have 

 subdivided the genus by its fruit, and the Linnaean Fu- 

 maria makes a whole natural order of M. DeCandolle. 

 I^innseus consitlered this as a genus in which one part of 

 the fructification ivanders, or is irregular, of which there 

 doubtless are many instances : but the present is an ex-
