How to Use

Pollen Microscopy prior to Identification

The Composite Profile Interface

Fig. 1. The opening interface with the initially accessible characters’ frames (15/25) including tip-texts, each being linked to its character states. 1: Colporate Pollen in Equatorial view; 2: Colporate Pollen in Polar view & 3: Porate Pollen in Polar view. The two buttons at the top right read Search and Results. Note the Percentage of Similarity.


The graphical interface starting with 15/25 frames (10 of them “indirectly” linked) is provided with: The Title bar; The Main Menu bar; The Toolbar & The Status bar.

Search & Results: Displayed on the Composite Profile Interface initially and after every validated graphical entry. After selecting several key characters via characters’ frames (see Fig. 1) clicking Search button brings the ‘Next’ discriminant characteristic interface with its states. This is possible only if the percentage of similarity indicates more than one species at 100%.

Select & Cancel: Displayed on the selected character interface. A click on either of these buttons will get you back to the Composite Profile Interface (the identikit).

Limitations of the Tool

This tool underscores the utility of Information Technologies in basic and applied Palynological studies. A multimedia self-tutoring tool, it will promote capacity-building in micro-taxonomic Pollen Science. Although tentative pollen typification is given for the listed taxa, authentication of some pollen types with overlapping characters should be done with discretion: : check your identification with the pollen slide collections housed at the Palynology Laboratories at the French Institute of Pondicherry (Institut Français de Pondichéry, India, IFP), Tropical Botanic Garden and Research Institute, Thiruvanathapuram, Kerala, India (TBGRI) and others. For more information on precise typification of pollen taxa, the users are referred to 8 volumes of Bibliographic Index to the Pollen Morphology of Angiosperms from 1972 to 1999.
