L62 ANTHOTAXY, OR INFLORESCENCE. 



I. BOTRYOSE TYPE. 



1. Simple, with lateral axes unbranched and terminated by a single flower, and 



Flowers on pedicels, 



Of somewhat equal length on a comparatively elongated axis, RACEME. 



The lower ones longer than the upper, and main axis short, . CORYMB. 



Of nearly equal length on an undeveloped main axis, . . UMBEL. 



Flowers sessile on a very short main axis, HEAD. 



Flowers sessile on a comparatively elongated main axis, . . . SPIKE. 



A fleshy spike or head is a ..." SPADIX. 



A scaly-bracted spike is an . AMENT or 



CATKIN. 



2. Compound, with lateral axes branched once or more, bearing clusters instead of 



single flowers. 



Irregularly racemosely or corymbosely compound, . . PANICLE. 

 Homogeneously and regularly compound, as 



Racemes in a raceme, COMPOUND RACEME. 



Corymbs coiymbose, COMPOUND COKVMB. 



Umbels in an umbel, COMPOUND UMBEL. 



Spikes spicate, COMPOUND SPIKE. 



Homogeneously compound, the secondary ramification 



unlike the primary, as Heads racemose, Umbels spiked, 



Spikes panicled, &c. 



II. CYMOSE TYPE. 



1. Simple, with terminal axis of each generation one-flowered. 



Mvnopodial, the axis of each generation evidently re- 

 solved into branches, TRUE CYME. 



These more than two, Pleiochasium or MULTIPAROUS CYME. 



These only two, . . . Dichasium, Dichutomous or BIPAROUS CYME. 

 Sympodial, the apparently simple axis continued by 

 a succession of new axes standing end to end, 

 Monochasium, False Raceme or Spike, Botryose or UNIPAROUS CYME. 

 Flowers one-ranked on one side of rliachis, HELICOID UNIPAROUS CYME. 

 Flowers two-ranked on one side of rhachis, SCORPIOID UNIPAROUS CYME. 



2. Compound, with terminal axes for one or more earlier 



generations bearing a cyme instead of a single 



flower, Various sorts of COMPOUND CYME. 



III. MIXED INFLORESCENCE. 



1. Anomalous simple, with unbranched one-flowered lateral 



axes (287), such as ... PARTLY REVERSED SPIKES OR RACEMES. 



2. Compound, of various combinations, of which there are 



names for the subjoined : 

 Primary inflorescence botryose, with axis elongating; 



secondary cymose, THYRSUS. 



Pair of such opposite cymes seemingly confluent round 



the main axis, . VERTICILLASTER. 



Panicle with some of the ramifications cymose, . . . MIXED PANICLE.
