GENERA 
I LAMIEÆ. 
1. Lamium T. — Flores irregulares; calyce tubuloso, campanu- 
lato v. turbinato, sub-5-nervi; dentibus 5, æqualibus v. inæqualibus, 
subulalis, nune rigidis v. pungentibus; postico nune (Leonurus) paulo 
majore, rarius (Wiedemannia) averso. Corolla 2-labiata; tubo intus 
nudo v. piloso-annulato; labio postico integro v. 2-fido fornicalo ; 
antici patentis lobis lateralibus nunc dente auctis; intermedio amplo, 
basi contracto, apice sæpius emarginato. Stamina didynama sub galea 
adscendentia ; anticis longioribus; antheris per paria approximatis; 
loculis 2, divergentibus v. demum divaricatis, dorso sæpe hirsutis. 
Disceus subæqualis. Germen 4-lobum; ovulo in lobis adscendente; 
micropyle extrorsum infera ; styli 2-fidi lobis subæqualibus subulatis. 
Achænia (nuculæ) 3-quetra, apice truncata v. concaviuscula ; mar- 
ginibus obtusis v. plerumque acutis. Semina adscendentia ; embryonis 
exalbuminosi v. nunc parce albuminosi radicula infera. — Herbæ an- 
nuæ v. perennes ; ramis 4-gonis ; foliis oppositis, dentatis, subincisis 
v. raro subpalmatifidis; verticillastris densis, œ-floris, aut axillari- 
bus, aut summis confertis terminali-capitatis. (Europa, Africa bor., 
Asia temp.) — Vid. p.1. 
2. Betonica T. — Flores fere Lamü; calyce tubuloso v. campa- 
nulato, 5-10-nervi; dentibus æqualibus, v. posticis majoribus, nunc 
in labium connatis; omnibus mutieis v. acutis, pungentibus molli- 
busve; addilis et nunc in sinubus dentibus paucis secundariis. Co- 
rollæ tubus reclus v. curvus, basi intus nudus, annulatus v. refraclo- 
pilosus ; limbi labiis sæpius valde inæqualibus, postico integro v. 
2-fido ; antico autem 3-fido patente; lobo mediante sæpius majore,
