When the partial peduncles diverge and hang loose, it is called 
& diffuse, and when they converge, it is called a close panicle. 
To these may be added the term Axilliares, (from axilla, 
the arm-pit) being such flowers as proceed from the angle 
formed by the leaf and the stem, as is most common: And 
Term in ales, being such flowers as terminate the stalk or 
branch. Also every other mode of flowering is called the 
Inflorescence, whether opposite the leaves, lateral, single, 
double* erect, bending, &c. 
* 
Under this head of Inflorescence may be explained Luxu¬ 
riant flowers, (commonly called double flowers) which, 
as they are considered only as varieties and unnatural, belong 
properly to the head, Habit of plants. A luxuriant flower is 
supposed generally to be owing to superabundant nourish¬ 
ment; the luxuriant part is generally the corolla, but sonie- 
times’the calyx also. It is divided into three degrees; 1st. 
inultiplicatus , 2d. plenus, 3d. prolifer. To which may be ad¬ 
ded, as an opposite imperfection, flos mutilatus. 
1st. Multiplicatus, (multiplied) when the petals of the 
Corolla are only so far multiplied, as to exclude part of the 
stamina; and it is called duplicate , triplicate , quadruplicate , 
&c. according to the number of rows of petals. 
2d. Plenus, (full) when the corolla is so much multiplied, 
as to exclude all the stamina ; which is occasioned by the sta¬ 
mina running into petals; and the flower is often so crowded, as 
toexclude or choke the pistillum also. Therefore,as the essential 
parts of generation are thus wholly, or in part destroyed, the 
plants become barren or imperfect, and no seed, or very little, 
can be expected from them.* Flowers with one petal are not 
very subject to fulness, when they are, it generally arises from 
an increase of the divisions of the petal. It is most usual in 
flowers of many petals, where it arises various ways ; some-i 
times by multiplication of petals only, sometimes of the 
calyx or nectarium, and sometimes of all. Compound flowers 
are also suject to luxuriance, arising several ways. 
* A remarkable instance of plenitude is in the gelder rose (viburnum opulus 
florepleno) where all the flowers are barren.
