Question: Are both Androsace and Metrosideros members of the Myrtaceae?

Context paragraphs:
Metrosideros leunigii: Metrosideros leunigii is the oldest described fossil species of the flowering plant genus "Metrosideros" (Family Myrtaceae), named from fossil flowers and fruits uncovered from the Oligocene (approx. 30 Million years) aged Little Rapid River deposit in Tasmania, Australia, as well as leaves from this deposit and identical leaves from the Eocene aged Hasties deposit, also in Tasmania.  These fossils are significant, because they show that "Metrosideros" once occurred naturally in Australia during the Cenozoic, and has since become extinct.

Metrosideros: Metrosideros is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the Myrtaceae family.  Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular.  The name derives from the Ancient Greek "metra" or "heartwood" and "sideron" or "iron".  Perhaps the best-known species are the pōhutukawa ("M. excelsa"), northern rātā ("M. robusta"), and southern rātā ("M. umbellata") of New Zealand, and "ʻ ōhiʻ a lehua", ("M. polymorpha"), from the Hawaiian Islands.

Metrosideros operculata: Metrosideros operculata is a species of flowering plant in the family Myrtaceae.  It is endemic to New Caledonia.  It usually grows as a shrub to 3 metres in height, or rarely as a small tree to 10 metres.  Stems are square in section and covered with silky hairs.  The stiff, pointed leaves have a slightly revolute margin and are linear to elliptic in shape.  They are 12 to 40 mm long and 3 to 10 mm wide.  White, pink or red flowers with 3 petals and between 50 and 120 stamens are produced in axillary inflorescences.

Metrosideros polymorpha: Metrosideros polymorpha, the ʻ ōhiʻ a lehua, is a species of flowering evergreen tree in the myrtle family, Myrtaceae, that is endemic to the six largest islands of Hawaiʻ i.  It is a highly variable tree, being 20 - tall in favorable situations, and a much smaller prostrate shrub when growing in boggy soils or directly on basalt.  It produces a brilliant display of flowers, made up of a mass of stamens, which can range from fiery red to yellow.  Many native Hawaiian traditions refer to the tree and the forests it forms as sacred to Pele, the volcano goddess, and to Laka, the goddess of hula.  ʻ Ōhiʻ a trees grow easily on lava, and are usually the very first plants to grow on new lava flows.

Metrosideros excelsa: Metrosideros excelsa, with common names pōhutukawa, New Zealand pohutukawa, New Zealand Christmas tree, New Zealand Christmas bush, and iron tree, is a coastal evergreen tree in the myrtle family, Myrtaceae, that produces a brilliant display of red (or occasionally orange, yellow or white) flowers made up of a mass of stamens.  The pōhutukawa is one of twelve "Metrosideros" species endemic to New Zealand.  Renowned for its vibrant colour and its ability to survive even perched on rocky, precarious cliffs, it has found an important place in New Zealand culture for its strength and beauty and is regarded as a chiefly tree ("rākau rangatira ") by Māori.  The blossom of the tree is called "kahika ".

Eremaea (plant): Eremaea is a genus of woody shrubs and small trees in the family Myrtaceae and is endemic to the south-west of Western Australia.  Little study of the genus as a whole had been undertaken until Roger Hnatiuk researched "Eremaea" and published a paper in 1993, "A revision of the genus Eremaea (Myrtaceae)" in Nuytsia.  The first species to be described was "Eremaea pauciflora" (as "Metrosideros pauciflora") in 1837 and by 1964, the number of species known had increased to 12.  Hnatiuk recognised 16 species, 5 subspecies and a number of varieties.

Metrosideros nervulosa: Metrosideros nervulosa, commonly known as the Mountain Rose, is a species of flowering plant in the family Myrtaceae.  It is endemic to Lord Howe Island in the Tasman Sea, part of the Australian state of New South Wales.  It occurs in shrubland or low forest, mainly at altitudes of 300–875 m on the main peaks of the island.  It prefers sunny positions on exposed ridges or in the forest canopy.

Puccinia psidii: Puccinia psidii is a rust (a type of plant pathogen) native to Brazil with a very broad host range in the myrtle family ("Myrtaceae").  "Puccinia psidii" can have very serious consequences to various species of plants in the Myrtaceae.  This family includes guava (the original host of this rust in Brazil), eucalyptus, melaleuca, and a number of species native to Hawaii, including some endemic species (found nowhere else on Earth) and at least one important native forest tree.  There are numerous strains of the "Puccinia psidii" rust—some known to be established in Florida, and at least one reported from California and there is concern that strains may exist or develop that could be devastating to ohia ("Metrosideros polymorpha"), one of Hawaii's dominant native trees, a foundation species for many remaining Hawaiian native ecosystems.  However currently, the major threat of Puccinia in Hawaii is the massive damage it is doing to "Eugenia koolauensis", a federally listed endangered species.

Metrosideros collina: Metrosideros collina is a species of flowering plant in the family Myrtaceae.  It is native to French Polynesia and the Cook islands.

Androsace: Androsace, commonly known as rockjasmine, is a genus in the family Primulaceae, second only to "Primula" in number of species.  It is a predominantly Arctic–alpine genus with many species in the Himalayas (where the genus originated), the mountains of central Asia, the Caucasus, and the southern and central European mountain systems, particularly the Alps and the Pyrenees.
