“…Engler, 1930c), and Elaeocarpaceae ( Sloanea p.p . ; Coode, 1983). Clearly, there is a fluctuation between the presence of lobed petals and the absence of petals within families, such as Cunoniaceae, Elaeocarpaceae and Anisophylleaceae, and in some cases even within a genus ( Ceratopetalum ; Hoogland, 1960;1981; Sloanea ; Coode, 1983; Combretocarpus ; Matthews et al.…”

Floral morphology, anatomy and histology were studied in representatives of all families of current Oxalidales, which were recently constituted as a result of molecular systematic studies by other authors, and are composed of families of different positions in traditional classifications (Oxalidaceae, Connaraceae, Brunelliaceae, Cephalotaceae, Cunoniaceae, Elaeocarpaceae, Tremandraceae). Two of the three pairs of sister (or nested) families that come out in molecular analyses are highly supported by floral structure: Oxalidaceae/Connaraceae and Elaeocarpaceae/Tremandraceae, whereas Cephalotaceae/Cunoniaceae are not especially similar at the level of Oxalidales. Oxalidaceae and Connaraceae share petals that are postgenitally united into a basal tube (although they are imbricate in both) but free at the insertion zone, stamens that are congenitally united at the base, uniseriate glandular hairs on the stamen filaments, and ovules that are hemianatropous to almost orthotropous. The sharing of a special type of sieve‐tube plastids and of trimorphic heterostyly, studied by other authors, should also be mentioned. With Brunelliaceae, the two families share an androgynophore and nectaries at the base of the stamens in alternisepalous sectors. Elaeocarpaceae and Tremandraceae share buzz‐pollinated flowers and a syndrome of features functionally connected with it. In addition, petals are larger than sepals in advanced bud, they are valvate, involute and enwrap part of the adjacent stamens, they have three vascular traces. Lignified hairs are common on the anthers and are found in the ovary locules and on the ovules (not lignified) of representatives of both families. Ovules have a chalazal appendage, and the inner integument is much thicker than the outer. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society, 2002, 140, 321–381.

“…For several taxa, fresh or silica-gel-dried material was not available for DNA extraction, so recently collected herbarium specimens were used. Representatives of each of the 12 currently recognized genera (Thompson, 1976;Coode, 1987;Coode 2004) were obtained: five species of Aceratium (of c. 20 species; Coode, 2004; distributed from Celebes and Moluccas, New Guinea, New Hebrides to northeastern Australia; taxa sampled from northeastern Australia and New Guinea), all five extant species of Aristotelia (southeastern Australia, New Zealand, Chile, Argentina; Coode, 1985), two species of Crinodendron (four species ;Bricker, 1991;central Bolivia, central and southern Chile, southeastern Brazil, northwestern Argentina; taxa sampled from northern and southern Chile), four species of Dubouzetia (c. 11 species;Coode, 1987; Moluccas, New Guinea, New Caledonia, N. Australia; taxa sampled from New Guinea, New Caledonia and N. Australia), 13 species of Elaeocarpus (no recent monograph available, but the number of species is probably at least 300; M. J. E. Coode, Royal Botanic Gardens Kew, personal communication; widespread in Southeast Asia and distributed west to India, Madagascar and Mauritius, north to Japan, east to Hawaii and south to Australia and New Zealand; taxa sampled from Australia, New Guinea, and New Zealand), both species of Peripentadenia (northeastern Australia;Coode, 1987), one of the two species of Platytheca (Thompson, 1976;southwest Western Australia), three species of Sericolea (c. 11 species; Coode, 1981;New Guinea), six species of Sloanea (c. 120 species; Earle- Smith, 1954;Coode, 1983;Smith, 1996;India, Indochina, South China, Malesia, Australia, New Caledonia, Madagascar, tropical Americas; taxa sampled from Australia, New Guinea, and the Caribbean), six species of Tetratheca (c. 50 species; Thompson, 1976; R. Butcher, Western Australian Herbarium, personal communication; southern Australia; taxa sampled from across the range), both species of Tremandra (Thompson, 1976;southwest Western Australia), and one of the two species of Vallea (Jaramillo Azanza, 1988; Chile, Ecuador) (Appendix).…”

To better understand the historical biogeography of the southern hemisphere and evolutionary responses of plants to aridity, we undertook a detailed phylogenetic study of the predominantly southern family Elaeocarpaceae sensu lato (including Tremandraceae). Plastid trnL-trnF and nuclear ITS sequence data were analyzed using parsimony and Bayesian methods and molecular evolutionary rates calibrated using the Oligocene fossil record of Elaeocarpus mesocarps to estimate the minimum divergence dates. The results indicate the monophyly of all recognized genera and a placement for the former Tremandraceae (three genera and about 49 species of shrubby, dry-adapted Australian plants) within the widespread predominantly rainforest tree family Elaeocarpaceae (nine genera, over 500 species). The former Tremandraceae clade diverged from its sister (Aceratium + Elaeocarpus + Sericolea) during the Paleocene, after which it underwent a marked acceleration in evolutionary rate. Furthermore, this lineage diversified during the late Miocene, coincident with widespread aridification in Australian environments and extensive radiations of several sclerophyllous groups. The role of dispersal in explaining the current geographical distribution of Elaeocarpaceae is illustrated by Aristotelia. This genus, whose distribution was previously thought to reflect Gondwanan vicariance, is shown to have arrived in New Zealand from Australia at least 6-7 million yr ago.

“…In contrast, Coode (1983) noted that Sloanea sogorensis, an Old World species (New Guinea), has compound young leaves. Several juvenile individuals of species of Sloanea were observed during field expeditions for this work, but none exhibited compound leaves.…”

“…Sloanea, the largest genus of the family Elaeocarpaceae, contains about 150 species distributed in Australia, Asia, Madagascar, South America, Central America and Mexico (Steyermark 1952;1978;1988;Smith 1954;1965;1967;1996;Coode 1983;Palacios-Duque 2004;2005;2007;Palacios-Duque & Fernándes-Alonso 2005;Sampaio & Souza 2010;2011a;b;Boeira et al 2012). In Brazil, the genus can be found throughout the country but particularly in more humid and preserved forest formations.…”

Th e genus Sloanea is comprised of 150 species, of which about 50 occur in Brazil among several vegetation types but mainly the Amazon and Atlantic forests. Th e present work provides a synopsis of the Neotropical species of Sloanea in the extra-Amazonian region based on a recent revision of the genus. In general, morphologically Sloanea comprises large trees endowed with buttressed roots; simple leaves; fl owers with sepals that may or may not cover the reproductive organs in pre-anthesis phases; stamens with the connective prolonged into an awn that is acuminate, acute or aristate and fruit covered with rigid or fl exible bristles or sometimes unarmed. Th is synopsis describes 17 species, and provides an identifi cation key, illustrations and comments on their diagnostic characters, geographical distribution and main bibliographic references.
