TitlePollenmorphology of Lysipomia H.B.K. and Rhizocephalum Wedd. (Campanulaceae) and the revision of the pollen determination “Valeriana stenophylla” Killip
JournalMededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht
AbstractFossil pollen grains from the Quaternary of Colombia, formerly provisionally indicated as “Valeriana” stenophylla Killip, have now been identified as those of the Andean genus Lysipomia H.B.K. (Campanulaceae).
In the genus Lysipomia s.l. (fide McVaugh) two considerably different pollen types are found: That of the Lysipomia s.s. and the Rhizocephalum type. The former was probably derived from the latter.
