Selaginella spec.

@Ina: Going close was necessary, this is a rather tiny plant :-)

@juant3: That was another tiny one and light was gruesome (lighthouse). Fortunately it was possible to make this shot without flashlight.

@Michael Skorulski: I've seen photos of Sellaginellae even with an more iridescent effect (changes from green to blue depending on the angle), I'm still looking for such a specimen.

@Japanalia: Yes, I love this green too! Their growth patterns are indeed very ancient, it's a very nice primitive plant!

@Jen: There's another Selaginella species that has iridescent colours, I hope to find it some day!

@JoeB: You wouldn't regret: they are very soft. In primeval times these plants were as big as trees of today.

@Anthony Lambert: Unfortunately they are not that easy to grow as the textbooks promise. I killed many of them by providing too much / less light, too much / less water and humidity etc. But they are beautiful little plants without doubt!

@Observing: Thanks Mike! To answer this question I could send you interesting links about evolution and diversity of plants. I want to recommend this book that tells it all.

@Evelyne Dubos: Thanks, Evelyne! In that greenhouse they had large mats of these Selaginellas, that was a very beautiful sight.

@Tracey: Thanks! I wished I had more of these, especially those with blue tones...

@MaryB: Growing them is a bit tricky. I achieved best results when growing them outside, indoors seems to be almost impssible!

@Michael: Danke! In der 'Flora' wächst das wie Unkraut, macht mich neidisch!
