Pericolporate pollen in Gentianaceae
Keyword(s):
Pollen of six species of Centaurium Hill. (Gentianaceae) was examined by photon and scanning electron microscope. Significant variation in pollen morphology occurs in all the taxa. Pericolporate pollen encountered in C. pulchellum, C. littorale ssp. littorale, and C. exaltatum is reported. The derivation of the pericolporate type of pollen from the tricolporate type in the genus is demonstrated.
