Pollen Description

Shape, Size and Aperture

pollen unit: monad,  dispersal unit and peculiarities: monad,  size (pollen unit): medium-sized (26-50 µm),  pollen class: -,  polarity: heteropolar,  shape: spheroidal,  outline in polar view: circular,  shape (dry pollen): irregular,  outline in polar view (dry pollen): irregular,  infoldings (dry pollen): irregularly infolded,  aperture number: 1,  aperture type: leptoma,  aperture condition: -,  aperture peculiarities: -

Ornamentation and Structure

LMornamentation LM: scabrate,  nexine: present,  sexine: present,  SEMornamentation SEM: microverrucate, microechinate, fossulate,  TEMtectum: eutectate,  infratectum: granular,  foot layer: continuous,  endexine: lamellar-continuous,  intine: -,  wall peculiarities: papilla, adhering Ubisch bodies

Miscellaneous

Annotations

exine ruptures near papilla when hydrated (before germination); protoplast with inner sporoderm layer becomes totally separated; for illustrations of the pollen wall ultrastructure see Uehara & Sahashi (2000)
