The lines between the segregate genera of Parodia (Notocactus, Brasilicactus, Eriocactus, etc.) have been clarified by recent work by Nyffeler who has shown that historical divisions are unjustified by the molecular (DNA) evidence. This offering is therefore better known as Notocactus graessneri var. albiseta (Cullman) Krainz. Nevertheless, it is not nearly as well known in cultivation as Parodia haselbergii (Notocactus haselbergii) with which it is now combined. Like that old favorite, it has globular stems densely clothed in pale spination with barely distinguishable centrals. In fact, these forms are so similar as to be indistinguishable in the vegetative state. The main difference is the vivid flower colors that are opposite but complementary. The familiar Parodia haselbergii has bright orange (red in brighter light) petals in an arrangement resembling the cellophane flourish atop a sandwich toothpick. The flowers of fa. albiseta have a similar, almost day-glow, quality but in emerald green. Plants from seed of HBG 61192, specimens from C&J Cactus Nusery in Vista, California. The species is native to the state of Rio Grande do Sul, Brazil. $6.
