 irregular. Calyx-tube adnate to the ovary ; limb usually 5-lobed or 5- 

 partite, exceptionally 3-10-partite; lobes equal or slightly unequal, 

 open valvate or imbricate in aestivation, usually persistent and enlarg- 

 ing after the corolla withers. Corolla gamopetalous, tubular campanu- 

 late rarely inf undibuliform or rotate, straight or oblique, limb regular 

 or oblique or bilabiate, lobes isomerous with the calyx, short or more 

 or less deeply divided, valvate or induplicate-valvate, rarely 1, 2 or all 

 the petals free. Stamens of the same number and alternate with the 

 lobes of the corolla commonly inserted on the disk, sometimes on the 

 tube of the corolla or adnate to it, filaments free from each other or 

 cohering at the top or throughout their entire length ; anthers linear 

 oblong or rarely ovate-free or connate in a tube around the apex of 

 the style, 2-celled, cells parallel, introrse, dehiscing longitudinally. 

 Ovary inferior half inferior or rarely almost superior, 2-5- or rarely 

 6-10-celled, the septa sometimes imperfect or disappearing early ; pla- 

 centas axile or attached to the middle of the septa, stipitate or peltate ; 

 ovules numerous or rarely only two at the base or apex of each cell. 

 Style simple, clavate at the apex, papillose, at first enclosed by the 

 anthers afterwards protruding beyond them, stigmatic lobes of the same 

 number as the cells of the ovary. Fruit capsular or baccate dehiscing 

 variously or indehiscent. Seeds usually small ; testa thin or coriace- 

 ous, smooth or reticulated ; embryo straight in the axis of the albumen.
