coloured bracts. The cymose inflorescence may be 

 a cincinnus, or form a head. The flowers are herma- 

 phrodite, irregular, zygomorphic, with the parts in 

 fives, with bracts. The calyx is inferior, hypogyn- 

 ous, tubular, five-lobed (or four to eight), over- 

 lapping in bud. The corolla is bell-shaped, with 

 a narrow tube, hypogynous, two-lipped, five-lobed, 

 overlapping in bud. The stamens are four (or five 

 or two) didynaraous, epipetalous, unequal. Two are 

 longer than the other two. They alternate with 

 the lobes of the corolla. The anthers are two- 

 celled and open inwards. The ovary is superior, 

 two- or four-celled, four-lobed, entire. The style is 

 sunk between the lobes of the ovary, terminal, simple. 

 The stigma is two-cleft, or simple. It is at first 

 bilocular, then divided into four or more loculi by a 

 false septum. The carpels possess two ovules, one in 

 each loculus after the septa are formed. The 

 placentae are axile. The solitary or two collateral 

 ovules are anatropous or orthotropous. The fruit 

 is a berry two- or four-celled, a drupe with two to 

 four stones, one- to two-celled, or a capsule or 

 schizocarp or nutlet (usually four in number). The 

 seeds possess no albumen. The cotyledons are leaf- 

 like. 



In the characters of the ovary the group differs 

 from the Deadnettle group to which, however, it is 

 most nearly related. There is some affinity also to 

 the Viper's Bugloss or Comfrey groups. 



The flowers are adapted to bees. The stigma and
