The pantropical flowering plant family Annonaceae is the most species‐rich family of Magnoliales. Despite long‐standing interest in the systematics of Annonaceae, no authoritative classification has yet been published in the light of recent molecular phylogenetic analyses. Here, using the largest, most representative, molecular dataset compiled on Annonaceae to date, we present, for the first time, a robust family‐wide phylogenetic tree and subsequent classification. We used a supermatrix of up to eight plastid markers sequenced from 193 ingroup and seven outgroup species. Some of the relationships at lower taxonomic levels are poorly resolved, but deeper nodes generally receive high support. Annonaceae comprises four major clades, which are here given the taxonomic rank of subfamily. The description of Annonoideae is amended, and three new subfamilies are described: Anaxagoreoideae, Ambavioideae and Malmeoideae. In Annonoideae, seven tribes are recognized, one of which, Duguetieae, is described as new. In Malmeoideae, seven tribes are recognized, six of which are newly described: Dendrokingstonieae, Fenerivieae, Maasieae, Malmeeae, Monocarpieae and Piptostigmateae. This new subfamilial and tribal classification is discussed against the background of previous classifications and characters to recognize subfamilies are reviewed. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 5–40.

“…Dasymaschalon Dalla Torre & Harms is unusual in possessing only three petals per flower; these petals, which are homologous to the outer petals of other Annonaceae, are apically connivent to form a pollination chamber (Wang, Chalermglin & Saunders, 2009; Saunders, 2010). Many species superficially appear to be cleistogamous, leading some authors (e.g.…”

The pollination biology of Annonaceae has received considerable attention, with data now available for > 45% of the genera (or genus‐equivalent clades) included in recent molecular phylogenetic analyses. This provides a basis for understanding evolutionary shifts in the pollination system within the family. The present study focuses on subfamilies Anaxagoreoideae, Ambavioideae and Annonoideae, for which robust, well‐resolved phylogenetic trees are available. Information is summarized on the pollination biology of individual clades and the evolutionary adaptations favouring different pollinator guilds evaluated. Although the majority of species of Annonaceae are pollinated by small beetles, five other pollinator groups are known: large beetles, thrips, flies, bees and cockroaches. Small‐beetle pollination is inferred as the ancestral pollination system, with all other systems being derived. Evolutionary shifts to pollination by large beetles, thrips and flies are unlikely to have been significantly constrained by previous adaptations favouring pollination by small beetles, as many of the adaptations to these different pollinator guilds are similar (including protogyny, partially enclosed floral chambers and olfactory cues). In contrast, however, the evolutionary shift to bee pollination has presumably been constrained by both protogyny (as pollen‐collecting bees are unlikely to visit pistillate‐phase flowers) and the presence of floral chambers. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 222–244.

“…Dasymaschalon is a much smaller genus, with only ca. 30 species which are endemic to tropical sub-tropical Asia (Wang et al 2009). The genus consists of small trees (rarely climbers), with indument of simple hairs (Li et al 2011).…”

“…Dasymaschalon was included within Desmos, but is supported by molecular studies and is easily distinguished morphologically by the absence of an inner whorl of petals (Wang et al 2009). To our knowledge, information is scarce on the chemical constituents of many of the Dasymaschalon species.…”

The compositions of essential oils of the leaves and stem barks of three Vietnamese species of Dasymaschalon J. D. Hooker & Thomson. (Annonaceae) were determined by means of gas chromatography and gas chromatography-mass spectrometry. Dasymaschalon longiusculum (Bân) yielded oils in which the major components were α-pinene (28.9% and 12.5%, respectively), β-pinene (26.5% and 13.3%, respectively), β-myrcene (12.0% and 6.0%, respectively) for the leaf and stem. The main compounds of the leaf and stem oils of Dasymaschalon glaucum Merr. & Chun. were α-pinene (14.4% and 10.5%, respectively), β-pinene (14.4% and 10.3%, respectively) and bicycloelemene (5.2% and 30.0%, respectively). The essential oil of Dasymaschalon robinsonii Jovet-Ast was different, mainly comprising α-copaene (12.7% and 16.6%, respectively), germacrene B (11.3% and 7.5%, respectively), δ-cadinene (5.6% and 5.3%, respectively) for the leaf and stem.
