LXXXTX. LABIATE, MINT FAMILY. 



Chiefly herbs, with aromatic herbage, square stems, opposite 

 simple leaves, more or less 2-lipped corolla (whence the name 

 of the order), either 4 didynamous or only 2 stamens inserted 

 on the corolla tube, 2-lobed stigma, and at once distinguished 

 from all the related families by the deeply 4-parted ovary (as 

 if 4 ovaries around the base of a common style), ripening into 

 as many seed-like nutlets (never prickly) or akenes, each con- 

 taining a single seed. Embryo usually filling the seed. As 

 in all these families containing bilabiate plants, there are 2 

 lobes belonging to the upper and 3 to the lower lip of the 

 corolla. Flowers from the axils of the leaves or bracts, usually 

 in cymose clusters, or running into terminal racemes or spikes. 

 The peculiar stamens of this family are shown in Lessons, 

 Figs. 300-305. 



Stamens 4, parallel and ascending, and projecting from a notch on the upper side 

 of the corolla. Nutlets reticulated and pitted, obliquely fixed by the inner side 

 near the base. 

 + Lobes of the corolla nearly equal and oblong, turned forward so that there seems to 



be no upper Up, the filaments conspicuously projecting from the upper side. 

 I. TKICHOSTEMA. Calyx 5-cleft in 2 lips, oblique. Filaments very long and slender, 



curved, coiled up in the bud.
