At time of 5mm length of alabatrum, the miosis in microsporecyte and the sex differentiation was found, thus in female flowers, pollen mother cell showed a abnormal meiose then the pollen cells gradually disintegrated, final, contabescence had taken, and in male flowers, the stamen normally developed.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
