A gamopetalous corolla sometimes has a fissure on one side extending nearly or entirely to the base as in the Lobelia (Fig. 96).

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 ap
