Yes, Kiky. There have now been four, but only 3 came through Orlando! There are now millions of people suffering a form of post-traumatic stress depression.
Thanks for the translations, Dick. Sometimes coincidences occur. A client last week decided to call a new venture "Pinestream" ... a variation on an established development in the area "Rio Pinar" ... river of pines. I will have to keep in mind that matsukawa has a similar meaning.
BTW, I take it you do not accept the writer's suggestion of a connection between matsukawabake & showa. Guess I'll have to find somebody to take that old magazine off my hands!

[For everyone else reading this, the inside joke is that I got the mag in question from Dick.] Your summary is consistent with what I have seen elsewhere. I have also read of there being two lines of Showa before Kobayashi improved it to be a worthwhile variety. One line created by Jintaro (Jyukichi Hoshino) from Ouchi and another raised by someone in Uonuma. ... and I have no idea whether those two places are anywhere close to one another or not!! I do wish there was a fully illustrated history of nishikigoi so the relationship with original varieties could be better understood. The notion of an Asagi red abdomen on a Matsukawabake sounded intriguing ... can imagine a pretty dramatic look. A strange variation on today's Beni Kumonryu, in reverse?
