Some special aspects, such as particular variations, ontogeny and origin, have been treated in later publications ( Weber, 1975, 1978 b, 1982, 1995). in virtually all descriptions of Penstemon and other genera of Plantaginaceae) or thought to be of rare and/or accidental occurrence and/or have been morphologically misinterpreted.Ībout 40 years ago, the author directed attention to this special type of cymes and realized its wide distribution in the Gesneriaceae and occurrence in a few genera of Scrophulariaceae ( sensu lato, s.l.) ( Weber, 1972, 1973). Although already noted by Bravais and Bravais (1837) and Wydler (1851 a, b), this type of cymes and the ‘supernumerary’ flowers within these cymes have been, and largely still are, either disregarded (e.g. Some taxa of Lamiales exhibit a special and otherwise unknown type of axillary inflorescences: cymes with flower pairs terminating the cyme units instead of single flowers (‘pair-flowered cymes’, PFCs).
