“…An interesting detail is that the individual flowers of morph B have a longer lifespan than those of morph A, because they have a functionless phase during the night. Kubitzki (1982) and Kubitzki & Kurz (1984) later found this kind of heterodichogamy in several other Lauraceae and assumed that it is probably widespread in those Lauraceae with bisexual flowers. As early as 1910, Wester mentioned that in Annona squamosa (Annonaceae) certain trees constantly shed pollen in the morning, others in the afternoon (Wester 1910).…”

In basal angiosperms (including ANITA grade, magnoliids, Choranthaceae, Ceratophyllaceae) almost all bisexual flowers are dichogamous (with male and female functions more or less separated in time), and nearly 100 per cent of those are protogynous (with female function before male function). Movements of floral parts and differential early abscission of stamens in the male phase are variously associated with protogyny. Evolution of synchronous dichogamy based on the day/night rhythm and anthesis lasting 2 days is common. In a few clades in Magnoliales and Laurales heterodichogamy has also evolved. Beetles, flies and thrips are the major pollinators, with various degrees of specialization up to large beetles and special flies in some large-flowered Nymphaeaceae, Magnoliaceae, Annonaceae and Aristolochiaceae. Unusual structural specializations are involved in floral biological adaptations (calyptras, inner staminodes, synandria and food bodies, and secretory structures on tepals, stamens and staminodes). Numerous specializations that are common in monocots and eudicots are absent in basal angiosperms. Several families are poorly known in their floral biology.

“…Its architecture in natural forest is described as tall with a small or narrow crown [41][42][43]. However, in the homogeneous plantations of Maués, as well as in the enrichment lines at Novo Aripuanã, tree architectures were variable enough that such a classification was not possible.…”

Rosewood (Aniba rosaeodora Ducke) is an endangered Amazonian tree species which produces one of the most valuable essential oils in the world. The species is used in silvicultural systems which are seen as a means to reducing the pressure of exploitation of natural rosewood populations. There are no specific equations for rosewood plantations, and therefore generalized equations are inappropriate for the species in commercial systems. This study presents allometric equations from 144 trees sampled in different rosewood plantations of Central Amazonia. The equations generated were compared with an equation used in forest management to estimate wood volume and another one recommended by law for rosewood biomass. The equation suggested by current legislation underestimates the actual values by more than 70% making the viable use of this equation impossible in commercial plantations. The equations generated to estimate the volume and biomass serve as an alternative to the need to develop specific equations for each area and age of the plant. The generic equation for the species is consistent for fresh mass management, with a generalized R 2 of 0.80 and an underestimation of 0.33%. The equation for crown fresh mass estimation presented a generalized R 2 of 0.32 and an underestimation of 0.24%. The underestimation of the mass production by rosewood plantations represents a serious impediment to this forest activity. The allometric equations developed are highly applicable under different conditions and management options and should be suggested by the legal provisions regulating rosewood-related activity in Central Amazonia.

“…Several species are known from few collections and have a narrow distribution. Other species have a wide distribution according to Kubitzki (1982); for instance, A. guianensis Aubl. and A. hostmanniana (Nees) Mez have been frequently collected and range from the Guianas to eastern Peru.…”

“…The most recent revision was published by Kubitzki (1982) who recognized 41 species. Kubitzki reduced several species to synonymy: of the six species described by C. Allen he accepted two; of the six species described by Kostermans he accepted three; and of the four species described by O. C. Schmidt he accepted one.…”

Five New Species of Aniba (Lauraceae) from Colombia, Ecuador, and Peru

Five new species of Aniba Aubl. (Lauraceae) with clustered or verticillate leaves are described and illustrated. Aniba brochidodroma van der Werff from Peru stands out by its short petioles and soft whitish hairs on the lower leaf surface. Aniba glabra van der Werff from Colombia is distinguished by its glabrous flowers and inflorescences. Aniba palaciosii van der Werff from Ecuador can be recognized by the indument of the outer surface of the tepals, with the outer three tepals finely appressed pubescent and the inner three tepals glabrous. Aniba tomentella van der Werff from Peru differs from its congeners in its flower shape; its flowers are wider than long and the tepals are incurved leaving only a small apical pore. Finally, A. verticillata van der Werff from Ecuador differs from morphologically similar species by its subcoriaceous leaves with prominently raised secondary veins and its montane habitat.
