216 DEFINITE INFLORESCENCES.—FASCICLE.—GLOMERULE. 
under the respective names of helicoid cyme or bostryx, and 
scorpioid cyme or ciciunus. Thus in what is termed the helicoid 
cyme, the successive lateral branches always arise from the 
same side,—that is, either right or left of the main axis (see 
page 110, and fiy. 216, 4), as in Hemerocallis ; while in the 
scorpioid cyme the successive lateral axes are developed alter- 
nately right and left of the main axis (see page 110, and fig. 
216, B), as in the Rock Rose (Helianthemum), and Sundew 
(Drosera). 
Both helicoid and scorpioid cymes have been commonly re- 
garded as sympodial inflorescences ; and to consist of a series of 
single-flowered axes, all of which are developed on one side as in 
the former, or alternately on opposite sides as in the latter. The 
investigations, however, in recent years of Kraus, George Hen- 
slow, Goebel, and other botanists, seem to prove that the scor- 
pioid cyme is not a sympodial development, but a monopodial or 
indefinite kind of inflorescence, or, in other words, a unilateral 
raceme. — 
Practically, the helicoid or scorpioid cyme, in the sense as de- 
fined by us above, may be distinguished from the ordinary raceme, 
at least when the bracts are developed, as follows :—thus, in the 
raceme, the flowers always arise from the axil of the bracts, 
while in the cyme they are placed opposite to the bracts (jig. 
442), or, at all events, more or less extra-axillary. But in those 
cases where the bracts are abortive, as in most plants of the 
Boraginacee, its discrimination from the raceme is often difficult, 
or even impossible, and its nature can only be ascertained by 
comparison with allied plants. 
Other views of the nature of these cymes have been also 
entertained by botanists ; thus, Kaufmann and Warming believe 
that bracteate scorpioid cymes arise from repeated dichotomy 
of the apex of an axillary bud. The further discussion of 
this subject, however, would be out of place in an elementary 
manual, and therefore for more detailed particulars we must 
refer our readers to Sachs’s ‘Text-Book of Botany,’ and to an 
article in ‘Trimen’s Journal of Botany,’ for January 1881, on 
‘The History of the Scorpioid Cyme,’ by Sydney H. Vines. 
c. The Fascicle or Contracted Cyme.—This name is applied to 
a cyme which is rather crowded with flowers placed on short 
pedicels of nearly equal length, and arising from about the same 
point, so that the whole forms a flattened top, as in the Sweet 
William and some other plants of the Pink order to which it 
belongs. 
d. The Glomerule.—This is a cyme which consists of a few 
sessile flowers, or of those where the pedicels are very short, 
collected into a rounded head or short spike. Examples may be 
seen in many Labiate plants, in species of Nettle, and in the Box 
(fig. 443). 
e. The Verticillaster.—This kind of cyme is seen in the
