TERMS INDICATING IRREGULARITY

the Hemispherical and the Crateriform or Saucer-shaped, as in the 

 Kalmia (Fig. 103). When still more flattened out it becomes Rotate 

 or Wheel shaped, as in the Solamim (Fig. 92). 



A gamopetalous corolla sometimes has a fissure on one side extending 

 nearly or entirely to the base as in the Lobelia (Fig. 96). When in 

 addition the corolla or the split portion of it loses its tubular form, 

 becoming flattened out, it is called Ligulate or Strap-shaped, as in the 

 DandeUon (Fig. 104). 



Special Forms of Perigone. — Fig. 92. Rotate corolla of Solanum, with connivent anthers. 93. 

 Campanulate corolla of Campanula. 94. Prismatic calyx and bilabiate, personate corolla of Mimulus: 

 a, the tube; b, the throat; c, the lower lip; d, the palate. 95. Contracted campanulate corolla of 

 LeucolhoS. 96. Fissured corolla of Lobelia. 97. Infundibular corolla of Spigelia. 98. Hypocrateri- 

 form corolla. 99. Cylindrical corolla. 100. Hypocrateriform corolla of Echiies with portion of tube 

 constricted. 101. Hypocrateriform corolla of coffee flower. 102. Urceolate corolla of Pernettya. 

 103. Crateriform corolla of Kalmia. 104. Ligulate corolla of Taraxacum. 



Accuracy Required in the Use of Terms. — The applicability to the tube 

 and limb separately of many of the terms here applied to the entire 

 corolla is apparent. It should be noted, however, that very detailed 

 descriptions of these respective parts, as well as of the throat, with 

 specification of any irregularities and marks, are often imperatively 

 demanded. This is especially true of the florets of the Compositae, 

 where such characters, although very slight, frequently serve for specific 

 distinction. 



Special terms for forms resulting from the possession of appendages 

 will be considered later. 



Terms Indicating Irregularity. — Terms indicating irregularity will next 

 be considered, commencing with those applicable to the entire body. 



Either the base or the mouth is Oblique when a plane transecting 

 it is not at right angles to the floral axis. The body is declined (Fig.
