Systematics of Austromyrtus, Lenwebbia, and the Australian Species of Gossia (Myrtaceae)

Two new species of Myrtaceae from Papua New Guinea

“…Unlike some species of Gossia from Australia (Snow et al 2003) and New Caledonia (Snow in prep. ), none of the species from smaller islands in the region (G. aneityensis, G. salomonensis) appear to be ecologically common.…”

“…On emerging branchlets they are scale-like and somewhat rounded. On older branchlets, and in the axils of bracteoles, the bases of the hair-like projections are notably swollen ("type B" stipules in Snow et al 2003). This stipule type does not occur on E. reinwardtiana or E. salomonica.…”

“…The species concept and terminology follow Snow (1997Snow ( , 2008 and Snow et al (2003). Geographical names follow Motteler (2006 [Snow et al 2003: 6-7; see also Fig.…”

“…Eugenia craveniana is tentatively placed in Eugenia because of its abbreviated bracteate inflorescence of uniflorous flowers, which are 4-merous, its bilocular ovary and peltate placenta with relatively few ovules, and dibrachiate hairs, all of which characterise a large percentage of species in Eugenia (excluding Hexachlamys O. Berg) (e.g., Landrum & Kawasaki 1997). The species resembles some in Gossia but does not match any species of Gossia known from Australia, New Guinea, or the Solomon Islands (Snow et al 2003;Snow 2005Snow , 2006. Examination of mature fruit would enable a definitive generic placement to be made, but because dibrachiate hairs are uncommon among baccate genera in Australia and New Guinea, and other characters of the flower are not aberrant in Eugenia (excluding Hexachlamys), we are confident placing the new species in Eugenia pending the hopeful re-collection of the species in fruit.…”

An expanded phylogenetic analysis of Sannantha (Myrtaceae) and description of a new species

“…In other genera of Myrtaceae, these structures have occasionally been interpreted as stipules (e.g. Weberling 1956Weberling , 1966Craven 1987;Snow et al 2003), sometimes with reservations. Recent work by da Silva et al (2012) has demonstrated that these 'stipules' are colleters, confirming the view of van Steenis (1969), and they identified three different types, namely, conic, petaloid and euryform.…”
