INFLORESCENCE. 
their number is then usually double the number of petals ; as in the 
pink, which has ten stamens and five petals. When inserted beneath 
the germ or base of the pistil, the corolla is said to be hypo-gynous, 
(underneath the style, or inferior ;) as in the stramonium. When it 
is inserted into the calyx and surrounds the germ, as in the currant, 
it is said to be peri-gynous, (around the style, or enveloping it.) 
When the corolla is inserted upoTj, the germ, as in the trumpet-honey* 
suckle, it is said to be epi-gynous, (upon the germ, or superior.) 
2d. The corolla with respect to the branches which support it. 
The disposition of flowers upon their branches is analogous to 
that of leaves ; thus, flowers are either radical, coming from the root, 
or cauline, coming from the stem ; they are peduncle or sessile, soli- 
tary, scattered, or opposite, alternate or axillary. Sometimes they 
are unilateral, growing on one side of the branch ; and sometimes 
fixed equally upon all parts of the peduncle, and pointing in different 
directions. 
3d. The corolla with respect to the Jiowers which surround it, or 
which groiD on the same peduncle. ' 
The different modes of division of the common peduncle, into 
lesser peduncles or supports, cause a great difference in the appear- 
ano^ ^d^situation of flowers, and exhibit a variety of forms of in- 
florescence. The green part which comes from the stem and sup- 
ports the flower, is called the peduncle ; sometimes it is called the 
foot-stalk of the flower or fruit. The divisions of the peduncle are 
called pedicels. 
When the plant is one-flowered, the flower is usually inserted at 
the end of the stemj the peduncle in that case is scarcely distinct 
from the stem. 
The most common kinds of inflorescence are as follows: 
Fig. 87. 
1st. Tfliorl, (Fig. 87,) an assemblage of 
flowers surrounding the stem, or its branch- 
es, constitutes a whorl, or ring: this is seen 
in mint and many of the labiate plants. 
Flowers which grow in this manner, are 
said to be verticillate, from the Latin verto, 
to turn. Leaves surrounding the stem in 
a similar manner, are said to be stellate, or 
star-like. 
What is said of the corolla with respect to the branches which support it?— With 
respect to the flowers which surround it? — Whorl.
