The reproductive organs in two species of Hymenena were examined on the basis of specimens collected in November 1980, by Drs. M. MASUDA and J. WEST at Duxbury Reef, and Mission Point, California. Hymenena flabelligera: 1) the procarps are initiated at randam in the younger tips of the frond, 2) the mature procarp consists of a four-celled carpogonial branch, two sterile groups, and the supporting cell, 3) before fertilization, the sterile cells usually number two, one in each group, 4) a fusion cell is present at the base of the gonimoblast, 5) the carposporangia are borne terminally, 6) the tetrasporangial sori are in narrow linear running lengthwise on upper half of blade, 7) the tetrasporangial primordia are cut off from inner cortical cells, and 8) the tetrasporangia are tetrahedrally divided. Hymenena multiloba: 1) the procarps are initiated in the younger parts of the frond, 2) the procarp consists of a four-celled carpogonial branch, two sterile groups, and the supporting cell, 3) prior to fertilization, the sterile cells usually number two, one in each group, 4) a fusion cell is present at the base of the gonimoblast, 5) the carposporangia are borne terminally, 6) the tetrasporangial sori are broadly linear, extending transversely across upper segment of blade, 7) the tetrasporangial primordia appear to be cut off from both primary and inner cortical cells, and 8) the tetrasporangia are tetrahedrally divided.
