Scientific Name Authorship

Lam.

Genus Authorship

L.

Morphology

Symmetry and Form

Monad, radial_symmetry, isopolar 3- (2- or 4-) colporate, elliptic in equatorial_view, circular to (sub)circular in polar_view

Dimensions

Polar_Axis = 22-29 µm; Equatorial_Axis = 20-26 µm

Apertures

Three colpora, a few 2- or 4- colporate grains, colpus elliptic, colpal apex acute, aperture_membrane psilate, distance between the adjacent colpal apices 8.0-10.0 µm, margo undifferentiated, costae_colpi present; Os: wide with uneven or irregular lateral ends, equatorially elongated tending to be synorate [See Fig. 3 in Muller, J. & Caratini, C. (1977) for variation in shape and fusion of endoapertures (os; pl. ora) in Rhizophora pollen], oral_costae present

Exine

Scabrate or granular (granule diameter = ±0.5 µm), tectate, infratectum columellate, exine thickness: at poles ±2.0 µm; at the mid-point of the intercolpium ±2.0 µm

Remark

6 species of Rhizophora based on SEM & TEM observations have been divided into 3 groups (Muller, J. & Caratini, C. 1977)

Tentative Pollen Typification

Rhizophora type (See Muller, J. Caratini, C. 1977)

(1969); SEM of R. mucronata (micro-perforate and scabrate) in Straka, H. & Friederich, B. (1984); LM of 7 spp. of Rhizophora in Thanikaimoni, G. (1987).
