originally diclinous, and which therefore profited by being always crossing ed with another individual, should have been converted into hermaphrodites, may perhaps be explained by the risk which they ran, especially as long as they were anemophilous, of not being always fertilised and consequently of not leaving offspring. This latter evil, the greatest of all to any organism, would have been much lessened by their being rendered becoming hermaphrodites, though with the contingent disadvantage of frequent self-fertilisation [text excised]
[Cross and self fertilisation, p. 410: "Why the descendants of plants which were originally dioecious, and which therefore profited by always intercrossing with another individual, should have been converted into hermaphrodites, may perhaps be explained by the risk which they ran, especially as long as they were anemophilous, of not being always fertilised, and consequently of not leaving offspring. This latter evil, the greatest of all to any organism, would have been much lessened by their becoming hermaphrodites, though with the contingent disadvantage of frequent self-fertilisation. By what graduated steps an hermaphrodite condition was acquired we do not know."]
