Oops, I accidentily wrote 'selenitica'
, but of course I meant pyrastri
! Sorry for this mistake. There are two old papers by Van Doesburg which deal with this 'var. unicolor'
, and he found several specimens of this abberation with incompletely developed ovaries. I do not have the references of these papers here, but I will let you know later.
