Herbs, some exotic species shrubby, with alternate entire dentate or lobed leaves, or the

 imbricated. Corolla irregular, spurred at the base, or the spur rarely obsolete, 2-lipped, the 

 upper lip erect, 2-lobed, covering the lower in the bud, the lower spreading, 3-lobed, its base 

 produced into a palate often nearly closing the throat. Stamens 4, didynamous, ascending, 

 included: filaments and style filiform. Capsule ovoid or globose, opening by I or more 

 mostly 3-toothed pores or slits below the summit. Seeds numerous, wingless or winged, 

 angled or rugose. [Latin, liniiui, flax, which some species resemble.] 



About 150 species, of wide geographic distribution, most abundant in the Old VVorld. Besides 

 the following, another occurs in southern Florida. The corolla, especially the terminal one of the 

 raceme, occasionally has 5 spurs and is regularly 5-lobed, and is then said to be in the Peloria state.
