Great Plants - Small Seeds

2013-02-01

 

As summer turns into autumn, the glory of the giant (about 1 meter tall) garden poppies  fades - and yet: The (over)ripe seed pods have their aesthetics too:

Tap such a seed pod lightly with a fingertip and out sprinkle the tiny  unimpressive seeds. At first sight they appear more or less like ground pebber:

 

Pentax K200D + SMC Pentax-FA 28-80 mm - 1/50 s; f/4; ISO 320


But take a closer look, and the appearance changes

Imagine, that these tiny "peanuts" may one day develop into metre tall magnificent flowers.

But there are even smaller "flower power children" - for example ferns that don't produce seeds but spores. If one has ever turned a bracken leaf during early summer time, one may have seen something like this:
 

Pentax K200D + Tamron SP 35-80 mm (Adaptall-2 system, Model 01A) + Tamron SP 01F teleconverter - 1/180s; f/11; ISO 200

 

These are the unripe spore houses that we see on the back side of the leaves. Now turn the leaves later on, and you may see something like this:

 

Pentax K200D + Tamron SP 35-80 mm (Adaptall-2 system, Model 01A) + Tamron SP 01F teleconverter - 1/180s; f/8; ISO 640


The spore houses have obviously changed. The have gotten a more frayed appearance, and if we go closer, we get a picture like this:

Myriads of spores are swarming out of their houses. Each has the potential to become a sturdy bracken. Well, that would really be quite a few....,
 

Technical note:
For the images that were made by means of
eyepiece projection was used a  Tamron Adaptal-2 CF Macro lens, Model 01A plus a 17 mm f/1.4 Eumig Euprogon projecting lens from an old Eumig 8mm film projector. In the set-up used, this has provided a reproduction scale of about  M = 2:1.

These old film projector lenses were designed to blow up the very small 8´mm image on the film to a large size on a screen and thus, they are also often well suited for use in macro eyepiece projection.
