1. Beneath the seed-vessel; example, the pea. See Plate,

IV. With respect to 7)iargw, the Calyx, may be — 



1. entire. 2. saw-toothed, (serrate.) 3. fringed with hairs, 

 (ciliated;) example (ceniiiurea) hiajj-iveed. 



V. The Calyx at the top, may be — 



1. acute or sharp, 2. prickly, (aculeated.) 3. blunt, 

 (obtuse.) 4. lopped, (truncate,) that is, with one of its indent-

VI. With respect to diiratioii, the Calyx may be — 



1. caducous, that is, falling off at the first opening of the 

 flower ; example, Jpoppy. 2. deciduous, falling off with the 

 corolla. 3. persistent, continuing until the fruit arrives at

Corolla, or Blossom. 



The leaves, generally coloured, of which the Corolla con- 

 sists, are csWed petals. 



The Corolla is either — 



1. Monope'talous, that is, one-petalled, the whole in one 

 petal. The one-petalled (monopetalous) Corolla, consists 

 usually of two parts : the tube, or lower part, and the limb, or 

 upper part, this latter usually spreads wider, (see Plate, 111. a. 

 the tube, b. the limb.) 



The Monopetalous Corolla, injigure is either — 



1. Bell-shaped, (campanulate,) that is, bellying out, with- 

 out any tube; example, bell-flo'wer, (campanula,) deadly- 

 night-shade, (Atropa.) See Plate, 120. 



2. Funnel-shaped (infundibuliform,) that is, tubular in the 

 lower, and conical in the upper part ; for example, the tobacco 

 plant, (nicotiana.) See Plate, 122. 



3. Salver- shaped, (hypocrateriform,) that is, with a flat 

 border, standing on a tube; for example, the primrose, (pri- 

 mula.) See Plate, 117. 



4. Wheel-shaped, (rotate,) that is, expanded, flat, without 

 any tube, or with a very short one ; for example, borage,
