110 Azolla filiculoides Lam. Azolla rubra Pacific Azolla Azollaceae








Megasporocarp less than 1 mm long containing a solitary megaspore (Sainty and Jacobs, 1981). Terminology for the part found in sedimentary records: 'megaspore' according to Birks (2007). Megasporocarp has 3 floats while that of Azolla pinnata has 9 floats. Present in seed reference collection. A free-floating aquatic perennial fern occurring on still of slow-flowing back waters of streams. Associated with the nitrogen fixing blue-green alga Anabaena sp. Apparently sporangia are often present but not fertile (Sainty and Jacobs, 1981). Plants are killed by drought.

Each massula has 64 microspores, has 1 or 2 obscure septae at the apex of the glochidia projecting from each massula (Willis, 1962, p.48). Field observations in Britain of Jones 1998 show that sporulation occurs between May and November (late spring to autumn) and where sporing was occurring, the Azolla formed thick mats p. 380. Increased phosphate resulted in increased megasporocarp production (often sporulation is associated with a decline in growth rate and might be followed by frond senescence) p. 383. Microsporangial massulae spherical, with prominent barbs all over (glochidia with hook-like tips) whereas in A. pinnata subsp. pinnata (the other Victorian species) the massulae is more or less conical with 1-6 non-barbed processes (no hook-like tips) towards one end.
