M.S., E.A. Ignatova, A.A. Belousova & A.O. Sigaeva. Additional observations on protonemata of Schistostega
pennata (Bryophyta)
Arctoa (2012) 21: 1-20
The
protonema of Schistostega pennata is well known due to its specific
structure, making it luminous in a cat-eye manner. The growth patterns of
protonemata are overviewed, including a filiform type that was not previously
described for this species. The latter, however, seems to be important for the
species, forming “bridges” between soil pieces and thus building its own
habitat. The sticky surface of propaguliferous protonemata is also capable to
stabilize surfaces where the species grows. Growth of protonemata is studied
both in nature and in cultivation, showing outstanding plasticity and ground-cementing
capacity.
