First, a little bit about evolution and phylogeny: there's reason to believe that cacti are relatively new as far as land plants go; from what I can tell they have no fossil record, but they're regionally bound to the new world. (Pediocactus simpsonii) https://t.co/G1IHVYMijh

Pretty sure it's Pediocactus simpsonii, but it could potentially be an escobaria species https://t.co/lLNYDMaj3i

Pediocactus の新棘はピンク色でマジ綺麗。私のプロフにしているのはPediocactus simpsonii RP4. 花もないうちに華があるのがPediocactus だと思う #Cactus #サボテン

一週間たって、良い感じに「台」木になってきた。届いたフッ素コーティングカッターもすごい切れ味だし、来週に接ぎ木を決行しようと思う。候補はG. berchtiiとUebelmannia pseudopectinifera. このままキープして実生中のPediocactus simpsoniiを接いでもいいな #Cactus #サボテン https://t.co/SB15anDpQg

Pediocactus simpsoniiも大きくなってきた。北見市の極寒で越冬できるか試そうと思っていたのだけど、転勤族は辛い #サボテン https://t.co/X6N3Mk6UJ9
