1230) "Pentagons in Nature", Belgium: "Geometry in Nature Series": Third Postage Stamps issue in the Series commenced in 2018: Stamp set issue date: 27.01.2020:

A series of Postage Stamps issued by Belgium Post features "Geometric Shapes found in Nature".

The Stamp Series which commenced on 11.06.2018, will issue five sets of stamps over a period of five years, since its commencement. The series began with the theme of "Spirals in Nature", with a pane of five stamps (2018) and continued with the theme "Star shapes in Nature" (17.06.2019).

The present Series shows "Pentagons". Each stamp is non-denominated, paying the basic rate for letter mail to European countries (presently at 1.55 Euros) and each design includes an outline of a Pentagon and a natural object or objects that appear to have five angles and five sides.

The stamp at upper left features the mineral Pyrite (also known as "Fool's Gold"). 

Soap bubbles are depicted on the stamp at lower left and in the selvage (derived from: A zone of altered rock, especially volcanic glass, at the edge of a rock mass) of the pane. The soap bubbles cling to each other, they are shaped like a pentagon.

The two stamps on the right side of the pane, show  photographs of plants forming pentagons - "Platycodon grandiflorus" commonly known as a "Balloon Flower" or "Bellflower", is pictured on the top Stamp and a cut section of Okra is at the bottom.

The selection taken on this Stamp set includes elements of the microcosm and macrocosm. At the microscopic scale it is easy to spot the Pentagons, which are found particularly in plankton and algae. The stamp images draw heavily from Nature's propensity to create such incredible Geometric figures.

The selvage on the right side of the pane depicts the five shapes to be featured in the "Geometric Shapes Found in Nature" Stamp Series - which will continue with "Circular Shapes" (2021) and end with "Hexagons (2022).
