COROLLA. 
the latin word verto to turn round. Leaves surrounding 
the stem in a similar manner are said to be stellate, or 
like a star. 
2nd. Raceme , or cluster consists of numerous flowers on its own 
stalk or pedicel, and all arranged on one common peduncle, 
as a bunch of currants. 
3d. Panicle bears the flowers in a kind of loose subdivided 
bunch or cluster, without any regular order ; as in the oat. 
A panicle contracted into a compact, somewhat ovate form, 
as in the lilac, is called a Tliyrse or bunch ; a bunch of 
grapes is a good example. 
4th. Spike ; this is an assemblage of flowers arising from the 
sides of a common stem ; the flowers are sessile or with 
very short peduncles ; as the wheat and the mullein. A 
spike is generally erect. The lowest flowers usually blos- 
som and fade before the upper ones expand. When the 
flowers in a spike are crowded very close, an ear is formed, 
as in Indian corn. 
5th. Umbel, several flower stalks of nearly equal length spread- 
ing out from a common centre, like therays of an umbrella, 
bearing flowers on their summits ; as fennel, and carrot. 
Gth. Cyme, resembles an umbel in having its common stalks all 
spring from one centre, but differs in having those stalks 
irregularly subdivided ; as the snow ball and elder. 
7th. Corymb, or false umbel, when the peduncles rise from dif- 
ferent heights above the main stem, but the lower ones be- 
ing longer, they form nearly a level or a convex top ; as 
the yarrow'. 
8th. Fascicle, flowers on little stalks variously inserted and sub- 
divided, collected into a close bundle, level at the top : as 
the sweet william ; it resembles a corymb, but the flowers 
are more densely clustered. 
9th. Head, or tuft, has sessile flow'ers heaped together in a glob- 
ular form, as in the clover, and the Button-bush, (Ccp/ia- 
lanthus.) 
10th. Ament or catkin, is an assemblage of flow'ers composed of 
scales and stamens arranged along a common threadlike 
receptacle, as in the chesnut and willow ; this is more par- 
ticularly described under the divisions of the calyx. The 
scales of the ament are properly the calyxes ; the w'hole ag- 
gregate, including senles, stamens or pistils, and filiform 
receptacle constitutes the ament.
