(3/5. H. Lecoq 'Etudes sur la Geogr.
Bot.' 1856 tome 5 page 325.) Now we know positively that, so far from Linum
perenne being fertilised by its own pollen in the bud, its own pollen is as
powerless on the stigma as so much inorganic dust.
Linum flavum.
The pistil of the long-styled form of this species is nearly twice as long as
that of the short-styled; the stigmas are longer and the papillae coarser. In
the short-styled form the stigmas diverge and pass out between the filaments, as
in the previous species. The stamens in the two forms differ in length; and,
what is singular, the anthers of the longer stamens are not so long as those of
the other form; so that in the short-styled form both the stigmas and the
anthers are shorter than in the long-styled form. The pollen-grains of the two
forms do not differ in size. As this species is propagated by cuttings,
generally all the plants in the same garden belong to the same form. I have
inquired, but have never heard of its seeding in this country. Certainly my own
plants never produced a single seed as long as I possessed only one of the two
forms. After considerable search I procured both forms, but from want of time
only a few experiments were made. Two plants of the two forms were planted some
way apart in my garden, and were not covered by nets. Three flowers on the long-
styled plant were legitimately fertilised with pollen from the short-styled
plant, and one of them set a fine capsule.
