This article enumerates the detailed anatomy of Cantinoa althaeifolia (Lamiaceae) illustrated with light and scanning electron microscopy images. The anatomical markers include the presence of branched nonglandular trichomes and capitate, peltate, and clavate types of glandular trichomes; prismatic crystals on the leaf and stem surfaces; and oil droplets in the leaf mesophyll. Histochemical tests and EDS analyses were performed in order to detect the composition of certain cells and their contents. The key findings of the present study can contribute to the taxonomy, species identification, and quality control of Cantinoa althaeifolia.

“…However, multiple layered epidermis have been reported in Piper species (Gogosz et al, 2012;Raman et al, 2012). Midrib shape and vascular pattern are useful markers to differentiate and identify Piper species (Santos et al, 2018). Although midrib shape was biconvex in all the examined species, each of them has some variations on either surface (Table 2).…”

“…Tetracytic stomata are common in Piper species (Santos et al, 2015;Bertocco et al, 2017). However, due to the presence of multiple types of stomata in case of inter-and intra-species this feature may not be helpful in the delimitation of species (Santos et al, 2018).…”

“…In our studied species of Piper the epidermis of midrib and lamina is uniseriate and covered with thin and smooth cuticle. Several studies have shown that leaf of Piper species exhibits single layered epidermis (Raman et al, 2012;Santos et al, 2015Santos et al, , 2018. However, multiple layered epidermis have been reported in Piper species (Gogosz et al, 2012;Raman et al, 2012).…”

The present study explores detailed morphoanatomical features of five species of Piper L., viz. P. betle L., P. longum L., P. nigrum L., P. retrofractum Vahl and P. sylvaticum Roxb. Each species is supplemented by detailed updated nomenclature, vernacular names, diagnostic characters, phenology, ecology and representative specimens. Maximum number of cortical and medullary vascular bundles have been observed in P. nigrum and P. retrofractum, respectively. In contrast, minimum number of cortical and medullary vascular bundles have been found in P. sylvaticum. Glandulartrichomes are found on the midrib of P. betle, P. longum, and P. sylvaticum, whereas trichomes are lacking in P. nigrum and P. retrofractum. The highest number of collateral vascular bundles have been found in P. retrofractum followed by P. nigrum, while P. betle and P. longum contain single collateral vascular bundle. P. betle can easily be distinguished from other species by its oval stem, non-glandular multicellular trichome with pointed tip, and presence of idioblasts and oil droplets. P. longum is distinct from remaining species by its diacytic stomata. Keys to the species based on morphological and anatomical characters are provided for easy identification of the studied species.

“…The essential oil production is related to the presence of secretory structures, such as idioblasts and secretory trichomes (Silva & Machado 1999, Marinho et al 2011, Tozin et al 2015. Idioblasts are present in all parts of P. aduncum plants, mostly in the leaves (Lakshmia & Naidu 2010, Marinho et al 2011, Gogosz et al 2012, Nakamura et al 2015, Santos et al 2018, which are the source for the highest amounts of essential oil. These secondary metabolism compounds are targeted by the chemical industry and present multiple biological effects exploited as insecticides, fungicides, molluscicides, acaricides, bactericides and larvicides, with the advantage of being biodegradable products (Zacaroni et al 2009, Costa et al 2010, Pino et al 2011, Piton et al 2014, Rapado et al 2014, Santos & Siviero 2015, Pinto et al 2016.…”

The growing of Piper aduncum for essential oil extraction has increased, but there is a lack of basic information about its management and cultivation, which allows the productivity and quality of the oil, in order to attend the market demands. This study aimed to evaluate the relation between the production of essential oils from P. aduncum and soil water pressure heads (20 kPa, 40 kPa, 60 kPa, 100 kPa and non-irrigated). The assessment comprised the quantification of idioblasts and the production of essential oil extracted from leaves of cultivated plants. The variation in the soil water pressure head alters the amount of idioblasts in P. aduncum leaves, with impacts on the essential oil production. A soil water pressure head range of 20-60 kPa is sufficient for this species to express the highest amount of idioblasts and the highest level of essential oil production. The species adapts itself to different water availability conditions in the soil. Under stress conditions, due to water deficit or excess, the production of essential oil is reduced.
