“…In both R. macrocarpa and R. verecunda this gelatinous material can be found adjacent to the cotyledonary end of the embryo in fruits that are immature. It is not known whether this endosperm persists in any mature seeds, so we support the position of Snow et al (2008) calling for more detailed studies on the embryology and seed status within Rhodomyrtus.…”

“…6H). The same embryo type also occurs in R. guymeriana N.Snow & J.P.Atwood and R. elegans (Snow et al 2008). A membranous layer, resembling a tissue-paper thickness skin, also surrounds the embryo of all four species.…”

“…The presence of endosperm in Rhodomyrtus previously has only been reported for the New Guinean endemic Rhodomyrtus guymeriana (Snow et al 2008), where they record endosperm as "gelatinous but scant". In both R. macrocarpa and R. verecunda this gelatinous material can be found adjacent to the cotyledonary end of the embryo in fruits that are immature.…”

“…Rchb. (Myrtaceae) is distributed from India and eastwards through southern Asia to New Caledonia and the Solomon Islands, including eastern Australia (Snow et al 2008). When Scott (1978) revised the genus there were 11 species with several infraspecific taxa recognised.…”

Rhodomyrtus verecunda A.J.Ford & Peter G. Wilson from north-east Queensland, Australia, is formally described and illustrated. Notes on habitat, distribution and conservation status are provided, as are details of how it can be distinguished from R. macrocarpa, the only other species of the genus in the region that lacks acrodromous venation. A revised key to the species of Rhodomyrtus in Australia is also presented.

“…For example, few species of Eugenia have winged or quadrangular branchlets, apically attenuate calyx lobes, costate fruits, or other qualitatively distinct character states that recur in many other baccate genera, and which simplify identifications and the writing of keys (e.g., Snow 2008; Snow et al 2001, 2008). Although additional undescribed species are known with a high degree of confidence, further research and more collections will be needed to produce a complete taxonomic treatment of the genus for Madagascar.…”

Snow & Callm., Eugenia tiampoka N. Snow & Callm., and Eugenia wilsoniana N. Snow, and one new combination, Eugenia richardii (Blume) N. Snow, Callm. & Phillipson is provided. Detailed descriptions, information on distribution and ecology, distribution maps, vernacular names (where known), digital images of types, comparisons to morphologically similar species. Preliminary assessment of IUCN risk of extinction and conservation recommendations are provided, including Vulnerable (4 species), Endangered (2 species), and Critically Endangered (4 species). Lectotpyes are designated for Eugenia hovarum H. Perrier, Eugenia nompa H. Perrier, and Eugenia scottii H. Perrier respectively.

The rainforest genus Gossia N.Snow & Guymer (Myrtaceae) occurs in Australia, Melanesia and Malesia, and is capable of hyperaccumulating the heavy metal manganese (Mn). Here, we used nuclear ribosomal and plastid spacer DNA-sequence data to reconstruct the phylogeny of 19 Australian species of Gossia and eight New Caledonian taxa. Our results indicated that the relationship between Gossia and Austromyrtus (Nied.) Burret is not fully resolved, and most Australian species were supported as monophyletic. Non-monophyly might be related to incomplete lineage sorting or inaccurate taxonomic classification. Bark type appears to be a morphological synapomorphy separating two groups of species, with more recently derived lineages having smooth and mottled ‘python’ bark. New Caledonian species were well resolved in a single clade, but were not the first diverging Gossia lineage, calling into doubt the results of a recent study that found Zealandia as the ancestral area of tribe Myrteae. Within Australia, the evolution of multiple clades has probably been driven by well-known biogeographic barriers. Some species with more widespread distributions have been able to cross these barriers by having a wide range of soil-substrate tolerances. Novel Mn-hyperaccumulating species were identified, and, although Mn hyperaccumulation was not strongly correlated with phylogenetic position, there appeared to be some difference in accumulation levels among clades. Our study is the first detailed phylogenetic investigation of Gossia and will serve as a reference for future studies seeking to understand the origin and extent of hyperaccumulation within the Myrteae and Myrtaceae more broadly.
