INTRODUCTION TO BOTANY. 113 
Branched, ramosus. ‘The main peduncle divided into 
secondary and third peduncles. Achillzea crithmifolia. 
Pl. Thies 2: 3 
4] Close, coarctatus. The peduncles are brought close to 
each other. Achillea millefolia, Sedum triphyllum, Mes- 
pilus monogyna, Cratzegus terminalis, Pyrus aucuparia. 
Loose, daxus. ‘The peduncles are far apart from one 
another. Ornithogalum umbellatum. 
_¥ Regular, regularis. The peduncles are so proportioned 
that all the flowers are on a regular height, either flat or 
convex. Achillea millefolia. Pl. 7, fig. 2. 
Irregular, irregularis. The peduncles are of such dif- 
ferent length, that the flowers are of an irregular height. 
Many of the radiated composite. 
The loose and irregular corymbi degenerate into panicles. 
The simple corymbi are only depressed racemes; in 
many of the cruciferze the original corymbus lengthens out 
into a raceme. ’ 
Muscarium. 
A corymbus of flowers not all on the same level.—Eu- 
patorium. 
CYyME. 
Cyma. The main peduncle throws out secondary peduncles 
from one and the same point, and these separate again into 
pedicels which spring from different parts of the secondary 
peduncles, and raise the, flowers nearly to the same height.— 
Sambucus, Cornus, Erythreea vulgaris, Nerium Oleander. 
The variations of it are nearly the same with those of 
the corymbus. 
BUNDLE. 
Fasciculus. The flowers are upright, grouped parallelly 
together very close, and are all nearly of the same height.— 
Dianthus barbatus, D. Carthusianorum. 
The variations. are but slight, and easily made out by 
analogy. 
UMBEL. us 
~Umbella. The flowers are borne upon peduncles springing 
_ from the same point, the branches being of an equal length. 
Simple, Umbella simplex. The peduncle only once di- 
vided into rays. Butomus umbellatus. Pl. 7, fig. 9.
