expansion of the flowers reveals its true nature. Examples are 

 seen in the Pelargoniums.

Fig. 232. Polychasiai cyme of Laurustmus^(Fi&!/rwf/;ft Tinus), 



e. The Verticillaster. — This is a very much condensed 

 cyme, the flowers of which have very short pedicels, and there- 

 fore appear almost sessile. 

 Fig. 23.S. The first axis gives rise to 



two branches, but the latter 

 and their succeeding branches 

 generally bear only one each. 

 The whole verticillaster ap- 

 pears much like a. cluster ol 

 sessile flowers. Instances of it 

 are afforded by most plants of 

 the natural order Labiates, 

 which bear two such cymes 

 in the axils of opposite leaves, 

 so that the flowers appear to 

 surround the stem. A pair 

 of such axillary cymes is 

 sometimes called a gloinerule {fig. 191). A modified form of 

 the glomerule is seen in the Nettle and the Box {fig. 233). 



B. Forms of Cymose Inflorescence with a Pseud-axis. 



These can be understood by a comparison of them with the 

 dichasium {fig. 234). Instead of the main peduncle bearing 

 two bracts each with a secondary axis in its axil, only one is
