Named in 1964 for its niobium (Nb) content and its leaf-like (phyllos) form, the first discovery of this very rare species was from Labrador in Canada. Since that time there have only been a handful of other world occurrences reported with Mount Malosa in Zomba District, Malawi being the most significant. This superb miniature specimen from Mount Malosa displays perfectly the radial leaf-like form of the crystals of this Astrophyllite Group species, with the individual brown blades reaching 4 cm in length. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
