and Stock, but sometimes without claws, as in the Celandine, 

 and the whole arranged in the form of a cross. 



2. Caryophyllaceous. — This consists of five petals, with long 

 claws enclosed in the tube of the calyx, and with their limbs 

 commonly placed at right angles to the claws, as in the Lychnis, 

 Single Pink, Carnation, Catchfly, &c. {fig. 460.) 



3. Rosaceous — This is composed of five petals, without, or 

 with very short claws, and spreading in a regular manner, as in

B. Irregular Polypetalous Corollas. — There are many anomalous 

 forms of irregular ])olypetalous corollas, as in tlie Monkshood 

 {Aconitum) {fig. 442.), Heartsease, &c., to which no particular 

 names are applied. There is one form, however, of such corol- 

 las, which is of importance, namely, 



The Papilionaceous. — This derives its name from the fancied 

 resemblance which it bears to a butterfly. It is composed of 

 five petals, one of which is superior and larger than the others, 

 and is termed the vevillum or standard {fig. 463, v) ; two in- 

 ferior, which are usually more or less united, and form a some- 

 what boat- shaped cavity {fig. 463, car), called the keel or 

 carina ; and two lateral {fig. 463, «) called wings or al(t. 



2. MoNOPETALous OK Gamopetalous Cokollas. — Whcn the 

 petals unite so as to form a monopetalous corolla, various terms 

 are used as in the case of the monose])nlous calyx to indit^ate the 

 degree of adhesion ; thus the corolhi may he partite, cirft, toothed, 

 or entire, the terms being ein])h)ytMl in the same sense as with 

 the calyx. The part also where the union has taken i)laco, is called 

 the tube; the free ]»ortion, the limb; and the orifice of the tube, 

 the throat or faux {fig. 464).
