Leaf glands are found in many Rhamnaceae species, the buckthorn family, and are frequently used in taxonomic studies of the group, especially because they are easily visible to the naked eye. Despite the many records and extensive use in the taxonomy of the family, few studies deal with the classification of these glands and their roles for the plant. Thus, this study aimed to unravel the type, functioning, and putative functions of the leaf glands of three Brazilian forest species: Colubrina glandulosa Perkins, Gouania polygama (Jacq.) Urb., and Rhamnidium elaeocarpum Reissek. Leaves were collected and processed for surface, anatomical, histochemical, and ultrastructural analyses. In addition, the presence of visitor animals was registered in the field. The leaf glands of C. glandulosa and G. polygama are defined as extrafloral structured nectaries due to their anatomical structure, interaction with ants, and the presence of reduced sugars and of a set of organelles in the secretory cells. The unusual mechanism of nectar release and exposure in an apical pore stands out in G. polygama. The glands of R. elaeocarpum are ducts or cavities that secrete phenolic oil resin. Their presence is an atypical condition in the family, although they are often confused with mucilage reservoirs, much more common in Rhamnaceae. The extrafloral nectary, secretory cavity, and duct are associated with plant protection against phytophages, either by attracting patrol ants or by making the organs deterrent. Our data, combined with other previously obtained data, attest to the great diversity of gland types found in Rhamnaceae species.

“…Ampelozizyphus is one the fourteen genera of the Rhamnaceae family occurring in Brazil as reported in the Brazilian Flora [15]. The genus was described in 1935 by Adolphe Ducke (1876-1959) based on specimens collected in Manaus at the Mindú and the Tarumã river waterfalls in Amazonas State [16]. Etymologically, when Ampelozizyphus was first described by Ducke, it was allied with Ziziphus Mill.…”

“…More recently, based on molecular phylogeny, the new tribe Ampelozizypheae was created to better accommodate the genus [18]. Nowadays, the genus includes three species but, until 2008, it was considered monotypic, with only a single species-Ampelozizyphus amazonicus Ducke (Figure 1)-characterized by a high-climbing lianoid habit, occurring in the terra firme lowland forests (altitude range of 50-300 m) of the Brazilian Amazon region, in the states of Amazonas, Pará and Roraima [16], as well as in Peru, Colombia, Venezuela, Guyana, Suriname and French Guiana [17].…”

The Amazon Forest is known all over the world for its diversity and exuberance, and for sheltering several indigenous groups and other traditional communities. There, as well as in several other countries, in traditional medical systems, weakness, fatigue and debility are seen as limiting health conditions where medicinal plants are often used in a non-specific way to improve body functions. This review brings together literature data on Ampelozizyphus amazonicus, commonly known in Brazil as “saracura-mirá” and/or “cerveja de índio”, as an Amazonian adaptogen, including some contributions from the authors based on their ethnographic and laboratory experiences. Topics such as botany, chemistry, ethnopharmacological and pharmacological aspects that support the adaptogen character of this plant, as well as cultivation, market status and supply chain aspects are discussed, and the gaps to establish “saracura-mirá” as an ingredient for the pharmaceutical purposes identified. The revised data presented good scientific evidence supporting the use of this Amazonian plant as a new adaptogen. Literature data also reveal that a detailed survey on natural populations of this plant is needed, as well as agronomical studies that could furnish A. amazonicus bark as a raw material. Another important issue is the lack of developed quality control methods to assure its quality assessment.
