    Notes: [Auszug] After acquaintance with several types of botanical training, and at the risk of appearing biased, I believe that something along the lines of the Cambridge system, as described by Prof. Briggs, meets several of the points raised and in particular has sufficient flexibility for the future ...

    Notes: [Auszug] The genus Ulva has also proved a rich source of new species, in many cases differing markedly from existing species. Cultural studies of two of the new species may result in their transfer to a new genus, because herbarium material suggests that the reproductive cells differ from the vegetative ...

    Submerged vegetation of the Rotorua and Waikato lakes 3. Lake Rerewhakaiitu (1975)
    Springer
    Hydrobiologia 47 (1975), S. 399-413

    Notes: Abstract The submerged and emergent aquatic macrophyte vegetation of the eutrophic Lake Rerewhakaiitu was surveyed in February–March 1973, and is described qualitatively. At the time the lowered lake level had resulted in producing a sward of normally submerged aquatics as land forms. The principal dominant in the sward is Myriophyllum propinquum, the plants being greatly reduced in length to short stems with single entire leaves. At the uppermost levels Tillaea sinclairii is a significant component of the sward, and at lower levels Lilaeopsis lacustris behaves similarly. Below the uppermost submerged belt of macrophytes there is a characean meadow of Chara fibrosa and C. australis which in deeper waters gives way to Potamogeton ochreatus with either C. australis or Nitella hookeri. The high degree of eutrophication and consequent low light penetration has resulted in a vegetation limit at 4.5–5 m, which is lower than that found in other Rotorua lakes.
