INFLORESCENCE. 



fugal evolutions, but is properly applied to that level-topped or fastigiate 

 form which resembles the corymb, as in the elder. If it is loosely- 

 spreading, not fastigiate, it is called a cymose panicle, as in the chick- 

 weed, spergula, etc. If it be rounded, as in the snowball, it is a globous 

 cyme.

358. A SCORPOID CYME, as seen in the sundew, Sedum," and borrage 

 family, is a kind of coiled raceme, unrolling as it blossoms. It is un- 

 derstood to be a half-developed cyme, as illustrated in the cut. 



359. THE PECULIAR EVOLUTION OP THB 

 CYME is well illustrated in the chick-weed 

 (Alsine media). The first opening flower 

 terminates the axis and stops its growth. 

 Then from the pair of axils next below issuo 

 two opposite branches, each bearing a pair 

 of leaves and a terminal flower. Next, tho 

 same process is repeated with each of these 

 two branches, and so on indefinitely. Thus 

 the stem becomes repeatedly forked, each 

 fork having an older flower in its angle. 



360. EVOLUTION OP THE SCORPOID RA- 

 CEME. But let only one branch be developed 

 at the node next below tho flower, and that 

 always on the same side, and wo have a 

 scorpoid raceme or cyme. Other f-regulari- 

 ties occasioned by partial development may 

 also variously disguise the cyme. 



361. FASCICLE. This is a modifi- 

 cation of the cyme, with crowded and 



nearly sessile flowers, as in sweet-william (Dianthus). 



362. GLOMERULE, an axillary tufted cluster, with a centrifugal evolu- 

 tion, frequent in the Labiatae, etc. When they occur in the axils of

 raceme.
