X is for Xylan, Xylose, Xerarch, Xerosere.

Day 24 of Blogging from A to Z.  Today’s letter is X

X is for Xylan, Xylose, Xerarch, Xerosere.

as meridies beats
the landscape’s xerarch creeps
toward xerosere as

sweet xylan begets
sweet nourishing xylose so
replacing dew’s kiss

Nature fascinates in its determined survival. Plants grow in the most unlikely places.

They didn’t sprout full blown in the deserts, mountains, seas, and places yet discovered; they evolved as yellow flowers on walk 3determined by the availability of light, water and surface.

The very rocks and pavements of humans eventually gives way to nature’s determination to bloom where she chooses.

 


 

Note: Xerosere is a plant succession which is limited by water availability. It includes the different stages in a xerarch succession. Xerarch succession of ecological communities originated in extremely dry situation such as sand deserts, sand dunes, salt deserts, rock deserts etc. A xerosere may include lithoseres (on rock) and psammoseres (on sand).
