15. 1892) in Sebdenia ceylanica from New Guinea has very dif-
ferent plurilocular sporangia or gametangia, which are finally
about 4 cells broad and 8 cells long; hairs are also manifest. In
the case of the Peruvian plant we have been able to find only one
possible hair protruding from the cortex of its host and even that
we have been unable to connect positively with the Streblonema.
