“…Based on the morphological traits, that is, curving stem, single rhizome, opposite alternative, or whorled phyllotaxis, axillary inflorescences having several flowers, long perianth, and with barriers in the segment, these species have been studied, which show numerous morphological diversity (Chien‐Ti & Yen‐Hsueh, 2019; Ying & Huang, 2000). It has been sub‐divided into three categories such as Polygonatum with alternative leaves, namely ( Alternifolia ); whorled leafy ( Verticillata ) and of raw leafy ( Oppositifolia ), having shouting stamen filaments, perforated pollen exines, and most of the pollen of Verticillatate section have opposite or vertical leaves with slender type filaments (Meng, Nie, Deng, Wen, & Yang, 2014).…”

In the current investigation, 16 samples of six species of the genus Polygonatum were collected from different geographical regions in China. Leaf micromorphological traits were studied in detail using scanning electron microscopy. About five-leaf samples were used for each species collected from different geographical regions. A significant variation was found in the foliar epidermal traits such as stomata types and their distribution, epidermal cell shape, anticlinal wall pattern, and various types of trichomes. Polygonal epidermal cells were observed in P. cyrtonema, P. odoratum, P. sibiricum, and P. filipes, rectangular in P. zanlanscianense and P. odoratum and irregular shape in P. filipes and P. zanlanscianense. Straight anticlinal wall pattern was observed in most of the species, but straight to little undulate was observed in P. cyrtonema, P. filipes, and P. zanlanscianense. Similarly, various shape stomata that are, oval, oblong, and elliptical and types that is, paracytic, anomocytic, and actinocytic have been observed. Based on the foliar traits, the P. odoratum and P. sibiricum were found closely related to one another. On the other hand, P. involucratum and P. zanlanscianense shows a strong association. However, P. filipes showed very less similarity with the other five species. Hence this study adds useful information that may be helpful in the further taxonomic classification of the taxa at subspecies level and was found significant in the correct identification and discrimination of the closely related taxa of the genus Polygonatum.

Polygonatum multiflorum (L.) All. (Asparagaceae) is a geophyte and remarkable forest species and the specimens have been collected from woodlands of highland forests in the Hyrcanian region. In this study, this species is described for the first time as a new record for the flora of Iran. Besides, based on localities of the observed and collected areas, the geographical distribution of the species is mapped in the Caspian forest zone from East to central parts of northern slopes of Alborz Mountain. According to the population status of the species, IUCN threat categories of these species have been discussed.

The current study analyzed the epidermal morphology of Asparagaceae in detail and assessed its systematic importance. At the familial level, no consistent characteristics were found, but anticlinal wall and stomata morphology provided systematic information of different tribes, especially Ophiopogoneae and Polygonateae. In Ophiopogoneae, Liriope and Ophiopogon had similar epidermis, which implying a close relationship between them, and was also supported by related studies. The leaves of Polygonateae exhibited rounded and undulate anticlinal wall. Polygonatum arisanense var. formosanum had a rounded anticlinal wall, whereas other species exhibited undulate anticlinal walls. Different epidemis of Po. arisanense var. formosanum supported the variety treatment of Po. arisanense. The intergeneric relationship was also interpreted based on the anticlinal wall and stomata. Therefore, the epidermis could provide the systematic value of Asparagaceae. The present study also revealed the linkage of stomata and habitat types, though the adaptative significance of epidermal traits needs further study.
