The pistil in the long-styled form is nearly twice as long as that of
the short-styled. In the latter the stigmas are smaller and, diverging to a
greater degree, pass out low down between the filaments. I could detect no
difference in the two forms in the size of the stigmatic papillae. In the long-
styled form alone the stigmatic surfaces of the mature pistils twist round, so
as to face the circumference of the flower; but to this point I shall presently
return. Differently from what occurs in L. grandiflorum, the long-styled flowers
have stamens hardly more than half the length of those in the short-styled. The
size of the pollen-grains is rather variable; after some doubt, I have come to
the conclusion that there is no uniform difference between the grains in the two
forms. The long-stamens in the short-styled form project to some height above
the corolla, and their filaments are coloured blue apparently from exposure to
the light. The anthers of the longer stamens correspond in height with the lower
part of the stigmas of the long-styled flowers; and the anthers of the shorter
stamens of the latter correspond in the same manner in height with the stigmas
of the short-styled flowers.
I raised from seed twenty-six plants, of which twelve proved to be long-styled
and fourteen short-styled. They flowered well, but were not large plants.
