Pollen morphology of the Bulgarian species from section Lathyrostylis (genus Lathyrus, Fabaceae)

摘要: The pollen morphology of five species from the section Lathyrostylis (Lathyrus, Fabaceae) distributed in Bulgaria (Lathyrus digitatus, L. filiformis, pallescens, pancicii and pannonicus) was studied with LO microscope SEM. grains are 3-zonocolporate, prolate, prolate-sphaeroidal oblatesphaeroidal type, medium size, elliptical or rectangular (quadratic) equatorial view circular to slightly triangular-obtuse-convex polar view. ornamentation is predominantly tectum perforatum (punctate-foveolate). (L. pallescens pancicii) should be differentiated into a new type Lathyrus filiformis.
