“…Senefeldera verticillata is a medium‐sized tree growing to about 30 m tall (http://onlinelibrary.wiley.com/doi/10.1111/aec.12082/suppinfo). It occurs mainly in the lowland Brazilian Atlantic Forest near the coast, in four states (from Bahia to São Paulo) from about 12°08′S to 23°37′S (Santos & Sales ). It is monoecious and bears mostly bisexual and male inflorescences.…”

Plant size, flowering synchrony and edge effects: What, how and where they affect the reproductive success of a Neotropical tree species

Plant reproductive success is supposedly influenced by phenology and individual size, which may be modified under edge effects. We tested if reproductive success, estimated by fruit set, in Senefeldera verticillata (Euphorbiaceae) is related to flowering synchrony and tree size, including plant height and circumference at breast height. The study was carried out in the interior and in edges of clearings for gas pipelines and electric lines of a lowland rainforest in south-eastern Brazil. Monthly observations were performed during one reproductive season, of 19 individuals that grew at edges of electric lines and gas pipelines and at forest interior. Reproductive success was significantly higher at forest interior than at gas pipeline area; there was no significant difference between gas pipeline and electric line areas or between forest interior and electric line area. In the forest edges, only plant height was positively related to plant reproductive success. This is probably related to crown exposure to sunlight, which enhances flower production. At forest interior, reproductive success was positively influenced by the synchrony of flowering activity among neighbouring individuals. In contrast, flowering synchrony based on phenophase intensity negatively impacted reproductive success. Senefeldera verticillata shows temporal dioecy and is mainly pollinated by small social bees, and the high degree of flowering synchrony at low intensity may increase the number of mating partners and therefore enhance its reproductive success. Inside the forest fragments, individuals with thicker trunks showed lower reproductive success, which may be related to a loss of reproductive capacity of older individuals. Our results evidenced the complexity of responses experienced by tropical plants subjected to forest fragmentation because of linear clearings.

“…Male and female flowers lack a perianth and have two nectaries at the base. The fruit is globose and greenish, with persistent stigmas; the seeds are pyriform, with caruncles (Santos & Sales ). Abscission of male flowers occurs when fruits begin to develop.…”

Microstachys crassifolia, a new species from Chapada dos Veadeiros region in the State of Goias, central Brazil, is here described and illustrated. Its habit and general morphology resembles that of M. nana Silva & Esser, an endemic species from the State of Paraná, southern Brazil. Both species are hemicryptophytes from grasslands, with a well-developed underground system, glabrous leaves and reddish inflorescences and fruits, but M. crassifolia has fleshy leaves without glands while M. nana has membranaceous leaves with pateliform, submarginal glands.Microstachys A. Juss. is a pantropical genus (Esser 1998) with about 20 species, five of them from paleotropical and Australian regions. The remaining species are found in the neotropics, with the center of diversity of the genus in central and eastern Brazil (Esser 1998, Silva andEsser 2011).Despite its great morphological variability, the genus can be recognized within Hippomaneae by its sub-shrubby habit, alternate leaves with mostly serrate margins, spiciform, leafopposite inflorescences, fruits that usually have spine-like appendages, and oblong seeds with truncate apex and a stipitate, lenticular caruncle (Esser 1998, Silva andEsser 2011
