“…Though Disporum comprises only 24 species, the genus is still taxonomically problematic and many species are difficult to identify, with either diagnostic characters too variable and/or obscure or having been provided with incomplete descriptions due to a lack of sufficient field investigations (Hara 1984; Hara 1988; Hareesh et al 2018). In an effort to achieve a better understanding of the taxonomy of Disporum , we have been working on the genus since 2016.…”

“…Disporum Salisbury (1812) includes about 24 species distributed in Bhutan, China, India, Japan, Korea, Laos, Malaysia, Myanmar, Nepal, Russia, Sikkim, Thailand and Vietnam (Liang and Tamura 2000; Li et al 2007; Hu et al 2016; Zhu et al 2016; Hareesh et al 2018; WCSPF 2018). According to Liang and Tamura (2000), there are 14 species in China, including 8 endemic species.…”

Disporum nanchuanense (Colchicaceae), a new species from Jinfo Mountain National Nature Reserve, Nanchuan District, Chongqing, China, is described and illustrated. It is similar to D. longistylum and D. megalanthum, but differs from the former in its stem branched type, tepals colour and size, stamens and pistil size; and it differs from the latter in inflorescence position, tepals shape, stamens position, pistil position and size. Meanwhile, the new taxon is assessed as Vulnerable (VU D2), according to the IUCN Red List criteria. Furthermore, an identification key to all Chinese species of Disporum is provided.

“…The micromorphological features observed using light and scanning electron microscopic (LM and SEM) analyses revealed taxonomically relevant characters for the identification of Korean Disporum species. Despite numerous recent discoveries of new species in the genus Disporum (Hareesh, Floden, & Sabu, 2018; Hu et al, 2016; Li et al, 2007; Zhu et al, 2016; Zhu et al, 2019), micromorphology has only been described in a limited number of taxa, and orbicular characteristics have never been studied in detail in Korean species (Lee, 1979; Lee & Yeau, 1990). The present study provides the first comprehensive description of orbicular, leaf and floral epidermal, and pollen micromorphology in Korean Disporum .…”

The genus Disporum Salisb. is widely distributed in East Asia, yet phylogenetically relevant morphological traits useful for differentiating many of the small, perennial, herbaceous species remain poorly described. To address this, leaf, floral, pollen, and orbicule micromorphology of four Korean Disporum species was investigated using light and scanning electron microscopy. All Korean Disporum species examined had hypostomatic leaves, with anomocytic stomatal complexes found only on the abaxial epidermis. Guard cell length varied among species, ranging from 44.30 μm in D. viridescens to 53.49 μm in D. uniflorum. The epidermal cells of the investigated Disporum taxa had sinuate anticlinal cell walls on both adaxial and abaxial surfaces. The surface of the guard and subsidiary cells were either smooth with weak striations or had strongly wrinkled striations. The pollen grains of all Korean Disporum taxa were monads, monosulcate with granular aperture membranes, subprolate to prolate in shape with microreticulate or verrucate exine surfaces. The mean size of pollen grains ranged from 46.38 to 49.92 μm in polar length and from 34.39 to 39.58 μm in equatorial diameter across species. Sexine ornamentation was a taxonomically relevant trait for differentiating Korean Disporum taxa. Additionally, the presence of orbicules as well as the orbicular characters (e.g., size, shape, ornamentation, and association pattern) are described for the first time in species from this genus. The present investigation of leaf and floral micromorphology using light and scanning electron microscopy provides valuable information for the taxonomic differentiation and identification of Disporum species in Korea. Research Highlights A detailed micromorphological description of leaf, floral characters (tepal, stigma, style), pollen and orbicule is provided for Korean Disporum species using scanning electron microscopy (SEM) and light microscopy (LM). The presence of orbicules and their taxonomic implications in Korean Disporum species are described for the first time. Phylogenetically informative pollen and orbicule micromorphological characters are described, improving understanding the systematic relationships of Korean species in the genus Disproum.

Over the past two decades, there has been a tremendous increase in the use of indigenous herbal medicinal plants in modern medicine; however, there is still a significant lack of research data in this field. This incomprehensive information base shades thedevelopment of a comprehensive research agenda especially in the context of developing Asian countries like Nepal. This chapter gives an overview of traditional medicinal plant Disporum Cantoniense,which is called hadjora (bone-joining) in Nepaliandhasbeen used since time unmemorable in case of bone fracture. Apart from this, D. cantoniense has various other medicinal uses in other regions around the globe. This chapter deals with overall aspects of D. cantoniense with sequential demystification thus enabling a greater understanding of its use and possibility to be used as alternative medicine in the future.©2022Caproslaxy Media.
