as in fruit crosses which I made, all the flowers were youngish, if any difference in maturity I probablytook same age – But with little crosses, & worsted crosses, as I never used pollen of same flower, I could hardly have taken anthers of same age.

Certainly there is no great difference in maturity on the anthers of two sets. If owing to maturity, we shd have to suppose (I imagine crosses to turn out as one appears May 4 1862) that crimson pollen was more mature & therefore more fertile with young pistil & that it becomes too old for old pistil as (I imagine) it is less fertile to old pistil than yellow pollen.

Monochætum ensiferum – fertilised last winter & gathered April & May 1862

Old flowers, with base of pistil straight

Monochætum ensiferum

yellow anther = sepal-faces black-thread & worsted

crimson anther = petal faces – white thread & worsted

Heterocentrum

purple-anther = sepal-faces nearest to pistil = black thread less fertile

yellow-anther = petal faces = white thread – most fertile

Now Heterocentron is in state of young flower of Monochætum; & I think it will turn out that in both plants the sepal-faces are less fertile with the rectangularly bent pistil – yet it is petal-faces which often at abort.
