Text: "The specimen cited (which is the only material I have found in any of the major Australian herbaria) bears the annotation in what appears to be Mueller's hand: 'Northern-Eastern boundary of N.S.W.' and on the line below, in the place where the collector of Mueller's specimens is indicated, is inscribed what appears to be a 'G' which I assume refers to W.R.Guilfoyle who is cited as the collector in the protologue. The material on the sheet comprises a leaf in two parts, the axes of an inflorescence and, in the packet attached, one complete, but dissected flower, several buds and numerous leaflets. The pinnae, in the limited sample available, occur in about 22 pairs with alternate leaflets in about 20 pairs. The sessile flowers have a calyx 10 mm long (including 3 mm long, ovate-deltate lobes); the corolla tube is c. 20 mm long with the narrowly lanceolate-triangular lobes 8 mm long and reflexed. The stamens are 40 mm long, with the tube exserted about 6 mm beyond the mouth of the corolla. Both calyx and corolla are densely and minutely golden brown-tomentose. This species was listed by F.M.Bailey (Syn. Queensland Fl. 146, 1883); subsequently (Queensland Fl. 520, 1900) he synonymised it under Pithecellobium moniliferum (DC.) Benth. Kostermans (1954) treated it as a synonym of Cathormion umbellatum (Vahl) Kosterm., a disposition accepted by Nielsen (1992) under subsp. moniliforme (DC.) Brummitt. It seems obvious that Bailey, Kostermans and Nielsen did not see the type, for the material represents a wholly different taxon. It is almost certainly a species of Serianthes Benth., a genus not known from Australia; however, I have not been able to match the specimen with any known species of that genus. See R.S.Cowan (Nuytsia 11: 16–17, 1996) for possible explanations of the puzzle."
