Re: Anchomanes ID, root quest.

YOU TOO? i think never is a very long time, and i too have grown many 
epiphytic plants, plants in baskets, and so-called normal plants, if 
Sansevierias can be called normal. stoloniferous roots will grow UP out of 
the soil, and will re-emerge even if you repot the plant with the roots 
buried. the underground roots of bamboo will make croquet wickets. maybe 
they are underground stems and not roots as such. when i had epiphytes, i 
enjoyed the roots greatly and looked at  them long and hard, and i cannot 
say they grew away from the light. orchid roots grew in same direction as 
the green stuff. ALSO, why would the Machine Who Built The Universe make 
roots capable of developing chlorophyll and doing the photosynthetic dance?

This is an oversimplification, but I do not believe roots are ONLY 
geotropic, and i bet i could induce roots to grow towards the light if that 
is where the water was.

And what about aquatic plants? and why would coralloid roots have a 
symbiotic relationship with algae if they were not light-adapted roots?

years ago the cactus and succulent growers did not like white pots as they 
allowed too much light into the soil and this did SOMETHING to the roots, 
but I cannot remember what it was. However, when i had those plants, i used 
white pots, because I had them around, as well as black pots, and I 
observed NO DIFFERENCE in the growth.

And then there is growing potatoes and yams in water.

so i do not think the secret of roots is fully grokked.

with unspeakable humble humility, i remain,
