Here's my question: in the Species Checklist, (most current from our SIGNA
folks) i. aphylla is noted as both having both diploid (2n=24) and
tetraploid (2n=48) forms. Does anyone know of the diploid form? I'm assuming
that the aphylla clones I am collecting are tets, as I'm trying to play
around with MTBs, but am also working the diploid lines. Don't want to waste
a bunch of pollen with a mismatch if I have some dips and tets in the
aphylla patch, which is growing...
