*1: On base of tree
fern ['trunk' (i.e. erect rhizome)], 30 m alt., Trebah
Gardens, SW7627, 7 Apr. 2005, JDS conf. HWM (Rothero 2009:
77); subsequently categorised as 'persisting introduction'
(Blockeel 2010: 55).
*2: On 'trunk' of tree
fern in outdoor garden, 100 m alt., Eden Project, SX047548,
2009, NGH 7512.
It was listed by Rothero (2010: 79) as a
'persisting introduction', defined by Blockeel (2010) as
present at the location for at least 10 years. However, when
the Eden Project opened in 2000 the outdoor gardens were of
small extent and lacked tree ferns, so the moss has certainly
not grown in this location for 10 years.
