OBJECTIVE Floral elaiophores, although widespread amongst orchids, have not previously been described for Maxillariinae sensu lato. Here, two claims that epithelial, floral elaiophores occur in the genus Rudolfiella Hoehne (Bifrenaria clade) are investigated. Presumed elaiophores were compared with

OBJECTIVE Recently, molecular approaches have been used to investigate the phylogeny of Oncidiinae. This has resulted in the transfer of taxa previously considered to be species of Oncidium Sw. into Gomesa R. Br. and the re-circumscription of both genera. In this study, the structure of the floral

We have characterized three C/D class MADS box genes from an orchid (Oncidium Gower Ramsey) and a lily (Lilium longiflorum). OMADS4 of orchid and LMADS10 of lily are C class gene orthologs, whereas OMADS2 of orchid is a putative D class gene ortholog. The identity of these three genes is further

OBJECTIVE Many orchid flowers have glands called elaiophores and these reward pollinating insects with oil. In contrast to other reward-producing structures such as nectaries, the anatomy of the elaiophore and the process of oil secretion have not been extensively studied. In this paper, elaiophore
