(3/7. 'Botanische Zeitung' September 18, 1863 page 281.) This is
the case with L. trigynum, which differs so much from the other species that it
has been formed by him into a distinct genus. (3/8. It is not improbable that
the allied genus, Hugonia, is heterostyled, for one species is said by Planchon
(Hooker's 'London Journal of Botany' 1848 volume 7 page 525) to be provided with
"staminibus exsertis;" another with "stylis staminibus longioribus," and another
has "stamina 5, majora, stylos longe superantia.") According to the same author,
none of the species which inhabit America and the Cape of Good Hope are
heterostyled.
I have examined only three homostyled species, namely, L. usitatissimum,
angustifolium, and catharticum. I raised 111 plants of a variety of the first-
named species, and these, when protected under a net, all produced plenty of
seed. The flowers, according to H. Muller, are frequented by bees and moths.
(3/9. 'Die Befruchtung der Blumen' etc. page 168.) With respect to L.
catharticum, the same author shows that the flowers are so constructed that they
can freely fertilise themselves; but if visited by insects they might be cross-
fertilised. He has, however, only once seen the flowers thus visited during the
day; but it may be suspected that they are frequented during the night by small
moths for the sake of the five minute drops of nectar secreted.
