Life History:
only plurilocular organs known from nature. These plants usually recycle themselves in culture. However, on rare occasions, unilocular plants have been found in culture. When cultures were started from these unilocular plants, plurilocular plants resulted, thus meiosis probably did not take place in the unilocular organ, and thus an alternation of generations may take place without a change in ploidy level (Loiseaux 1970b, p. 257) Display references
