Re: Yet more from the Haematococcus culture jar

Re: Pencil wood-shavings
Fantastic that you image captured: 'round bordered pits'...of secondary-growth zyleme (secondary growth zyleme=wood!). Your use of a lead pencil-sharpener to get your samples is so ellegant, Gekko! I'm now thinking that we can determine if the 'wood' is angiosperm tree wood...or conifer tree wood......
