“…A strictly Neotropical tribe with six capsular-fruited genera. Compared to Renner's circumscription (Renner, 1993), it now contains genera formerly in the Bertolonieae (Macrocentrum and Salpinga) and excludes some genera now recovered in the Sonerileae or Cambessedesieae (Goldenberg et al 2008, Cotton et al 2014, Dellinger et al 2018, Bacci et al 2019, Bochorny et al 2019. Issues persist on the systematics of every genus in the tribe (Mendoza-Cifuentes and Fernandez-Alonso 2010, Dellinger et al 2018, thus the current taxonomy will surely change in the near future.…”

“…A strictly neotropical and recently described tribe that includes three genera: Cambessedesia, Huberia and Merianthera (Bochorny et al 2019). Cambessedesia was traditionally placed in the Microliceae (Cogniaux 1891, Renner 1993, but seed morphology (Almeda and Martins 2001) and molecular data (Fritsch et al 2004, Goldenberg et al 2012 have shown that it did not belong in this group (Goldenberg et al 2012).…”

“…Huberia and Merianthera, along with Behuria and Dolichoura were placed in the Merianieae (Cogniaux 1891, Renner 1993. The latter two genera have been included within a larger Huberia (Bochorny et al 2019). There is a monograph for Merianthera (Goldenberg et al 2012), and a synopsis for Huberia sensu stricto (Baumgratz 2004).…”

The following guide is aimed at aiding in the curation of herbarium collections in Melastomataceae, with an emphasis on the New World species. It contains a summary of the taxonomic realignments at the tribal and generic level within Neotropical taxa of Melastomataceae, as well as some general comments for other groups. A table with a generic linear sequence is also provided, as well as tables with new and synonymized New World genera since 2005 and all currently accepted species. Lastly, a table with the synonyms of over 1000 accepted Neotropical species that have been impacted by these generic realignments is also provided.

“…Our study species, Huberia bradeana Bochorny & R. Goldenb. (formerly Dolichoura spiritusanctensis Brade), belongs to tribe Cambessedesieae (Bochorny et al 2019) and presents stamens with a prominently prolonged, ‘whip‐like’ dorsal connective appendage (Fig. 1; Goldenberg & Tavares 2007).…”

Connective appendages in Huberia bradeana (Melastomataceae) affect pollen release during buzz pollination

et al. 2021

Floral structures, such as stamen appendages, play crucial roles in pollinator attraction, pollen release dynamics and, ultimately, the reproductive success of plants. The pollen‐rewarding, bee buzz‐pollinated flowers of Melastomataceae often bear conspicuous staminal appendages. Surprisingly, their functional role in the pollination process remains largely unclear. We use Huberia bradeana Bochorny & R. Goldenb. (Melastomataceae) with conspicuously elongated, twisted stamen appendages to investigate their functional role in the pollination process. We studied the effect of stamen appendages on pollinator behaviour and reproductive success by comparing manipulated flowers (appendages removed) with unmanipulated flowers. To assess bee pollinator behaviour, we measured three properties of buzzes (vibrations) produced by bees on Huberia flowers: frequency, duration and number of buzzes per flower visit. We measured male and female reproductive success by monitoring pollen release and deposition after single bee visits. Finally, we used artificial vibrations and laser vibrometry to assess how flower vibrational properties change with the removal of stamen appendages. Our results show that the absence of staminal appendages does not modify bee buzzing behaviour. Pollen release was higher in unmanipulated flowers, but stigmatic pollen loads differ only marginally between the two treatments. We also detected lower vibration amplitudes in intact flowers as compared to manipulated flowers in artificial vibration experiments. The presence of connective appendages are crucial in transmitting vibrations and assuring optimal pollen release. Therefore, we propose that the high diversity of colours, shapes and sizes of connective appendages in buzz‐pollinated flowers may have evolved by selection through male fitness.

There is little direct evidence linking floral development and pollination biology in plants. We characterize both aspects in plain and ornamented flowers of Trimezieae (Iridaceae) to investigate how changes in floral ontogeny may affect their interactions with pollinators through time. METHODS:We examined floral ontogeny in 11 species and documented pollination biology in five species displaying a wide range of floral morphologies. We coded and reconstructed ancestral states of flower types over the tribal phylogeny to estimate the frequency of transition between different floral types.RESULTS: All Trimezieae flowers are similar in early floral development, but ornamented flowers have additional ontogenetic steps compared with plain flowers, indicating heterochrony. Ornamented flowers have a hinge pollination mechanism (newly described here) and attract more pollinator guilds, while plain flowers offer less variety of resources for a shorter time. Although the ornamented condition is plesiomorphic in this clade, shifts to plain flowers have occurred frequently and abruptly during the past 5 million years, with some subsequent reversals.CONCLUSIONS: Heterochrony has resulted in labile morphological changes during flower evolution in Trimezieae. Counterintuitively, species with plain flowers, which are endemic to the campo rupestre, are derived within the tribe and show a higher specialization than the ornamented species, with the former being visited by pollen-collecting bees only.
