248 BOTANY. 
enclosing the pileus or head of a fungus; and which, after the 
plant has arrived at maturity, contracts and remains on the 
stem, or at the root. 
Every corol is either monopetalous, consisting of one petal 
or flower-leaf, or polypetalous, consisting of more than one. 
The monopetalous corols are divided into — 1 . Bellform. — Hol¬ 
lowed out within the base, as gentian, Canterbury-hells, &c. 
2.Funnelform. —With a tubular base and the border opening 
gradually like a tunnel, as in the thorn-apple and morning-glo¬ 
ry. 3. Salverform. —Having a flat spreading limb or border, 
proceeding from the top of a tube, as lilac, trailing arbutus, &c. 
4. Wheelform. — Having a spreading border without a tube, 
or with an exceeding short one, as borage and laurel. 5. Labi¬ 
ate. — It is divided into two general parts, somewhat resembling 
the lips of a horse or other animal. Labiate corols are either 
personate (with the throat muffled), as snapdragon; or ringent 
(with the throat open), as mint, motherwort, and catnip. Pol- 
ypctalous corols are divided into — 1. Cruciform. — Consisting 
of four equal petals spreading out in the form of a cross, as rad¬ 
ish, cabbage, mustard, &c. 2. Cary aphyllous. —Having five 
single petals, each terminating in a long claw, enclosed in a tu¬ 
bular calyx, as pink, catchfly, cockle, &c. 3. Liliaceous. — A 
corol with six petals, spreading gradually from the base, so as 
altogether to exhibit a bellform appearance, as tulip, lily, &c. 
4. Rosaceous. — A corol formed of roundish spreading petals 
without claws, or Avith very short ones, as rose, apple, straw¬ 
berry, &c. 5. Papilionaceous. — A flower Avhich consists of a 
banner, two wings, and a keel, as pea, clover, &c. If a corol 
agrees with none of the above descriptions, it is called anomalous. 
The stamen is divided into—1. Anther. — The knob of the 
stamen, which contains the pollen; very conspicuous in the 
lily, &c. Never Avanting. 2. Pollen. — The dusty or mealy 
substance contained in the anthers. Never Avanting. 3. Fila¬ 
ment. — The part of the stamen Avhich connects the anther with 
the receptacle, calyx, or pistil. Often Avanting. 
The pistil is divided into—1. Stigma. — The organ which 
terminates the pistil; is very conspicuous in the lily, and
