style rising from the centre, and shortly cleft at the top into 2 
stigmatic lobes. Fruit enclosed in the persistent calyx, separat- 
ing into 4 small, 1-seeded and seed-like nuts. 
A vast family, spread over every quarter of the globe, and readily 
known from all Monopetals, except Boraginec, by the 4-lobed ovary and 
the 4 small nuts resembling naked seeds in the bottom of the calyx; 
and from Boraginec by their opposite leaves, the want of the fifth 
stamen, and usually by the more irregular flowers. Most of the species 
have also a peculiar strong scent, either highly aromatic in many of our 
potherbs, or as disagreeable in several species of Stachys. Distinct, 
however, as the whole family is, the genera into which it has been 
divided are much less so than could be wished. Those especially 
which are allied to Stachys are separated from it by slight differences 
-in the shape of the calyx and corolla, which are not always easy to 
appreciate. 3
