Behind alien appearance of this Marchantia is a simple plan: grow, bifurcate, repeat. Result: ever-expanding, fractal-like circle of thalloid liverwort greatness! Eye-like structures are gemmae cups w/ tiny clones- zoom in to see them waiting for rain-splash dispersal.

Photographing oil bodies is tricky. Here are leaf cells of Lophozia bicrenata, with chloroplasts (green and plastered to cell walls) and oil bodies (grey and floating in cytoplasm). Note variation in number of oil bodies per cell (2 to 10). Splendid little things😀

Beautiful specimen of complex thalloid salebrosum (‘snakewort’) on seepy ledge in neUS. Its reptilian appearance due to dark grooves tracing outlines of air chambers in thallus, each crowned by light green air pore... no stomates for this !

Random movement of liverwort oil body (Lophocolea semiteres) due to bombardment by other (invisible) moving particles in the cytoplasm. Known as Brownian Motion, named after the Scottish botanist Robert Brown. Length of oil body = 0.01 mm.

On our wander today I found Riccia fluitans or Floating Crystalwort while trying to get samples of duckweeds from the wetland we were in. Never come across this before. Luckily Mary, our moss recorder, knew exactly what it was straight away. Experts eh?

What kind of funny face is this? It was growing in a big flowerpot containing a blueberry plant. It's a tiny (1 cm²) .

Encouraging amounts of fertile Petalwort (Petalophyllum ralfsii) at Newborough Warren (Wales) presently, here showing a male with antheridium arrowed. Could be a good sporophyte season for this declining dune slack specialist. Survey for .

This remarkable creature is Snakeskin (Conocephalum), largest of its non-vascular kind in neUS. Tiny dots on surface are air pores (no stomates here!) Otherwise silent & still, male plants eject 2-tailed gametes in startling puffs of air- see:

Minute or photosynthetic ? This tiny sp. was growing on moist sediment of recently dried ephemeral pool wetland in neUS. Thalli are just ~1 mm wide! No polytomies here... all !
