Although E. speciosum is commonly
fertile (and then distinct in being synoicous; autoicous
plants not seen in Cornwall), it is easily overlooked as the
commoner E. hians when
non-fertile (although distinguishable by the longer cells of
the stem-leaves, mainly >70 µm) (see also notes under O.
hians
). Note that Smith (1978, 2004) gave
erroneous cell measurements and other misleading
comments.
Habitat notes from Cornwall are as follows. On wet
ground and trickles of water in flushes on and above
sea-cliffs (of granitic and other rocks, gabbro), often part
shaded. Associates include Agrostis stolinfera, Pellia endiviifolia.
Near small rocky (granite) streams and trickles on coastal
slopes, partly to well shaded by scrub and low trees. On soil
under tall Grey Willow carrs, in areas occasionally flooded,
shaded or only part shaded. Edge of stream shaded by old Grey
Willow carr and deciduous trees, where subject to occasional
inundation. Small flush under old Grey Willows (with Aneura pinguis, Chiloscyphus
polyanthos s.
l.).
Commonly [?] c.fr.: capsules immature 8-11;
dehisced 4.
