Cal. tubular, angular, with 5 marginal teeth, one of them 

 rather shorter than the rest. Cur. unequal ; tube cylin- 

 drical, twice as long as the calyx, straight and slender in 

 the lower half, dilated and curved in the upper part; 

 limb spreading, in 5 deep, rounded, somewhat unequal 

 segments. Filam. 4, in some species but 2, slender, very 

 short, incurved, within the tube of the corolla. Anth. 

 incumbent, each of 2 round lobes. Germ, superior, qua- 

 drangular. Style slender, the length of the tube. Stigma 

 obtuse. Seeds 2 or 4, oblong, angular and roughish, en- 

 closed in one thin, membranous, evanescent pellicle. 



Most of the species having 4 stameyis, 2 long and 2 short, 

 this genus is more commodiously placed here than in 

 Diajidria, where Linnaeus introduces it. The covering 

 of the seeds is a real pellicle, not a pericarp, which is 

 evinced by the whole structure of the genus, and its evi- 

 dent affinity to the rest of the Didynamia Gymiwspermia, 

 not at all to the Angiospermia, This pellicle is similar 

 to that of Chenopodium, see vol. ii. 9 ; and Grammar 26. 



Herbaceous, rarely shrubby. Leaves either undivided, cut, 

 or laciniated ; sometimes 3 in a whorl. FL spiked, nu- 

 merous, small, blue or purplish.
