“…In addition, the occurrence of secretory cavities and/or canals in vegetative and/or reproductive organs may be taxonomically important, and help to identify genera and species of Leguminosae (Turner 1986;Lersten & Curtis 1996;Teixeira & Gabrielli 2000;Leite et al 2014).…”

Secretory spaces in species of the clade Dipterygeae (Leguminosae, Papilionoideae)

Dipteryx, Pterodon and Taralea are legume genera known for secreting oils, produced in secretory canals and cavities, with medicinal properties. We analyzed the distribution, morphology and histochemistry of these glands in leaves and stems of Dipteryx alata, Pterodon pubescens and Taralea oppositifolia, three Neotropical species, using standard techniques for anatomy and histochemistry. Secretory spaces, i.e. secretory cavities and canals, exhibited a wide lumen and a single layer of epithelium. Digitiform epithelial cells, forming trabeculae protruding into the lumen, were seen in all three species. Secretory cavities with a rounded or oval lumen and secretory canals with an elongated lumen in longitudinal sections were found only in T. oppositifolia. In D. alata and P. pubescens, only secretory cavities were found. In P. pubescens, secretory cavities occurred in the leaf blade margin. In T. oppositifolia, secretory spaces were much more numerous than in the other two species. Terpenes, total lipids, phenolic compounds, alkaloids and polysaccharides were detected in the secretory spaces of the three species. Th e abundance of secretory spaces, the presence of canals in T. oppositifolia and the position of cavities in P. pubescens are features with potential diagnostic value for their respective genera.

Lotus is a taxonomically difficult genus. No worldwide taxonomic studies for the whole genus have been produced since the monograph of Brand (1898). A comprehensive taxonomic revision of the genus is needed (Degtjareva et al., 2006). In Egypt, Lotus L. is represented by 18 taxa (Boulos, 2009). The species of Lotus constitute complexes of closely related groups with similar vegetative characters, including seasonal polymorphisms (Heyn, 1970), and it is difficult to distinguish among the species (Ojeda et al., 2009). Several studies have demonstrated the use of micromorphological characters to differentiate between some taxa

“…The absence of secretory trichomes in the flowers of Caesalpinia echinata does not reflect the condition of the other species in the Caesalpinia clade, considering that Erythrostemon gilliesii and Poincianella pluviosa present these structures in the flowers and in the axis of inflorescence (Souza et al 2013), and that other species of the clade potentially bear floral secretory trichomes since these structures have been reported to occur in the vegetative organs of approximately 100 species (Ragonese 1973;Leelavathi & Ramayya 1983;Lersten & Curtis 1994;1996;Rudall et al 1994;Lewis & Schrire 1995;Simpson & Miao 1997;Pascal et al 2000;Warwick & Lewis 2009;Melo et al 2010).…”

“…2). Interestingly, although their presence is a wide condition in legumes, their distribution and morphology are highly variable and of potential systematic value for some groups such as cavitated trichomes in the genus Bauhinia (Duarte-Almeida et al 2015;Marinho et al 2016) and the trichomes present in species of the Caesalpinia clade (Ragonese 1973;Leelavathi & Ramayya 1983;Lersten & Curtis 1994;1996;Rudall et al 1994;Lewis & Schrire 1995;Simpson & Miao 1997;Pascal et al 2000;Warwick & Lewis 2009;Melo et al 2010) and in the genus Mimosa (Santos-Silva et al 2013). Our reports of floral secretory trichomes are original for 11 of the 15 species studied belonging to the Cassia, Dimorphandra, Mimosoideae and Papilionoideae clades.…”

Beyond pollination: diversity of secretory structures during flower development in different legume lineages

et al. 2017

View full text Add to dashboard Cite

Floral secretory structures are usually associated with the attraction of pollinators, but may also play an important role in the mechanisms of plant protection. Th is study aimed to show the diversity of secretory structures present in the developing fl owers of 15 legume species belonging to diff erent clades and to associate them with functions other than the pollinator attraction. Buds, fl owers and developing axis of infl orescence were processed for surface, histological, and ultrastructural analyses. Th e species investigated displayed a wide diversity of secretory structures in developing fl owers such as phenolic cells and/or tissues, mucilaginous cells, secretory cavities, secretory trichomes and colleters. Each type of secretory structure exhibited variation in morphology and location in the fl ower and/or axis of infl orescence depending on the species. Special mucilage cells, secretory cavities, secretory trichomes and colleters have great potential for comparative morphological studies due to their diversity of forms or restricted occurrence to certain taxa, contributing to a more robust morphological data base for the new clades emerging in Leguminosae. Th e scarcity of reports about fl oral secretory structures of Leguminosae seems to be more related to defi cient sampling than to the absence of such structures in the group, which highlights the need for further investigation.
