“…In addition to species of the families Solanaceae, Fabaceae, and Melastomaceae, Myrtaceae species are also visited to obtain pollen, as observed in the present study and reported by Bittrich et al [62] for Euglossa sp., by TorezanSilingardi and Del-Claro [63] for El. nigrita, and Falcão et al [64] for Eulaema mocsaryi (Friese, 1899).…”

In spite of playing an important ecological role as pollinators of tropical ecosystems, orchid bees are still poorly known regarding their floral resources. Aiming at a better comprehension of the importance of different plants visited by the Euglossini and, consequently, their role in the maintenance and reproduction of plant species in tropical ecosystems, this study aimed at identifying the flowers visited by those bees in two different areas of the Atlantic Forest in the northern coast of the state of São Paulo, Brazil. Sampling was carried out from August 2007 to July 2009 in two coastal ecosystems in Ubatuba, Brazil. In order to obtain information on flower resources collected by Euglossini beesin loco, all bees observed on flowers were collected, pollinaria of Orchidaceae occasionally attached to the body of males were identified, and the pollinic analysis of 68 females was carried out. One hundred twelve bees from 14 species were associated to 105 plant species which represented pollen, nectar, resin, and fragrances sources. These data reinforce the relevance of orchid bees to the maintenance and reproductive success of many tropical plants.

“…In most flowers adapted to buzz-pollination, the anther walls control pollen dispensing onto buzzing bees. There are now at least three examples in which the floral perianth has been evolutionarily co-opted into this function: the Madagascar Dalechampia reported here, Ternstroemia in the Theaceae (Bittrich et al 1993), and Pedicularis in the Orobanchaceae (e.g., Macior 1968Macior , 1973.…”

FLORAL PAEDOMORPHY LEADS TO SECONDARY SPECIALIZATION IN POLLINATION OF MADAGASCARDALECHAMPIA(EUPHORBIACEAE)

et al. 2012

The traditional evolutionary interpretation of Von Baer's "laws" of embryology is that retention of early developmental forms into adulthood (paedomorphosis) leads to the evolution of simpler or more generalized morphology and ecology. Here we show that paedomorphosis can also be involved in an increase in ecological specialization, in this case of plant-pollinator relationships. A paedomorphic transition from generalized pollination (by several functional types of pollinators) to specialized pollination (by one or a few species in one functional type) occurred in a clade of endemic Madagascar vines (Dalechampia spp., Euphorbiaceae). This evolutionary transition involved staminate flowers that fail to develop "normally," instead holding mature pollen inside virtually unopened, bud-like flowers. This paedomorphic morphology restricts reward access to "buzz-pollinating" bees, including Xylocopa species (carpenter bees), which can remove pollen by sonication. This is one of very few reports of paedomorphic specialization, and, as far as we are aware, the first documented case of a rapid reversal to specialized pollination in a lineage of plants that had previously switched from specialized to generalized pollination in conjunction with dispersing to a new region.

“…Poricidal anther dehiscence has been associated with buzz pollination in other groups (e.g., Senna , Solanum , Ochnaceae, etc. ); Bittrich et al. (1993) presented evidence of buzz pollination for Archytaea and two species of Ternstroemia that have longitudinal anther slits, by female bees of Aucochloropsis , Bombus , Euglossa , Melipona , and Xylocopa .…”

This work represents the first phylogenetic analysis of all genera belonging to the plant family Theaceae (sensu lato). The study is based on 60 morphological characters derived from herbarium specimens and an extensive literature review of 37 genera (including the outgroup). In contrast to the results from molecular data, Theaceae is here found to consist of one clade in which the recognition of two families or subfamilies would leave Theaceae s.s. paraphyletic. Within that clade, Ternstroemiaceae is supported as
