“…Comparisons with other similar Nothapodytes species were based on the existing literature (Sleumer 1940, 1969, 1971, Howard 1942, Peng and Howard 2008) as well as the study of herbarium specimens (mainly in HITBC and KUN). The morphological data of digitized specimen images were analyzed using MATO (Liu et al 2023). The primary sources of digitized specimens were CVH (http://www.cvh.ac.cn), GBIF (http://www.gbif.org), and Global Plants on JSTOR (https://plants.jstor.org/).…”

Nothapodytes burmanica Y.H.Tan & S.K.Shen, sp. nov. (Icacinaceae) from Kachin State, Myanmar is described and illustrated. It belongs to Nothapodytes due to the lorate hairy petals being connate at the base and a fleshy foliaceous disk divided into five leaflike lobes. Morphological and phylogenetic evidence indicates that it is close to N. pittosporoides. Morphologically, both species have oblanceolate or oblong leaf blades that are adaxially sparsely pubescent, but the new species is distinguished by its leaf base usually being oblique, and the paniculate inflorescence that has more numerous but smaller flowers with shorter petals. Phylogenetic results indicate that N. burmanica is deeply nested within the genus and forms a sister group of N. pittosporoides.

“…Then, we randomly selected twenty pollen of each species to observe and photograph their shape and the equatorial and polar views under a light microscope (Olympus-BX51) at 10 × 100 magnification. Finally, MATO v4.2 software [ 36 ] was used to measure the pollen size, including the polar axis length (P) and the equatorial axis length (E) of pollen. In addition, we also calculated the ratio of polar axis length and equatorial axis length (P/E).…”

The genus Sanicula L. possesses many medically important plants, belonging to the family Apiaceae. It is one of the most taxonomically difficult taxa, largely due to the great variability in habit, foliage, flowers and fruits. Previous studies have mainly focused on the molecular studies of this genus, and the morphological research for this genus was limited, especially in the micromorphological research. In the current study, we newly obtained leaf materials from twenty-two Sanicula members, fruit and pollen materials from twenty Sanicula members and performed comprehensively micromorphological analyses for this complicated genus. The results of the leaf epidermis showed that the upper and lower epidermis were smooth and glabrous, and the cell shape was polygonal or irregular. The patterns of anticlinal wall were shallowly undulating, deeply undulating, subflat or flat. The cuticular membrane ornamentations were diverse, and some species had epidermal appendage. All Sanicula species observed the stomata in the lower epidermis, and only five species (S. rugulosa, S. elongata, S. hacquetioides, S. tienmuensis and S. elata) observed stomata in the upper epidermis, which can easily identify them from other Sanicula members. In addition, we found that the fruits scarcely compressed, and some fruits had their distinctive shape, such as the fruit shape of S. tienmuensis was subglobose, S. subgiraldii was broadly ovate and S. pengshuiensis was ellipsoid. All Sanicula taxa fruits surfaces were covered with prickles, bristles, protuberance, or tubercles, prickles were either long or short, uncinate or straight, rarely scale-like, ribs inconspicuous or slightly prominent, but the prickles/bristles/tubercles were different in shape, sparseness and arrangement. The vittae were distinct in S. rubriflora, S. chinensis, S. caerulescens, S. pengshuiensis, S. pauciflora, S. lamelligera, S. oviformis, S. flavovirens and S. elata, and the remaining taxa were obscure. These findings indicated that the fruits can clearly distinguish these Sanicula members. Furthermore, the micromorphological characteristics of pollen showed that the equatorial view included four shapes: ellipsoid, subrectangular, equatorially constricted and super-rectangular-equatorially constricted; and the polar view possessed four shapes: triangular, triangular–circular, suborbicular and trilobate circular. The germ furrow and the outer wall ornamentation of all Sanicula taxa were quite similar, indicating that the genus was a natural unit. In summary, our study promoted the improvement of a taxonomic system for the genus and also provided additional evidence for future taxonomic study of the genus Sanicula.

“…There were thirty representative fruit samples for each species (ten individuals from each species, each with three fruits) selected to observe their morphological characters, and then their overall structure and anatomy were photographed using a stereo microscope (SMZ25, Nikon Corp., Tokyo, Japan). The software MATO ( Liu et al., 2023b ) was used to measure the thirty representative fruit samples for each species, and then the average value was calculated. The terminology followed the reported study ( Kljuykov et al., 2004 ).…”

IntroductionThe genus Sanicula L. is a taxonomically complicated taxa within Apiaceae, as its high variability in morphology. Although taxonomists have performed several taxonomic revisions for this genus, the interspecific relationships and species boundaries have not been satisfactorily resolved, especially for those endemic to China. This study mainly focused on S. giraldii var. ovicalycina, S. tienmuensis var. pauciflora, and S. orthacantha var. stolonifera and also described two new members of the genus.MethodsWe newly sequenced sixteen plastomes from nine Sanicula species. Combined with eleven plastomes previously reported by us and one plastome downloaded, we performed a comprehensively plastid phylogenomics analysis of 21 Sanicula taxa. Results and DiscussionThe comparative results showed that 21 Sanicula plastomes in their structure and features were highly conserved and further justified that two new species were indeed members of Sanicula. Nevertheless, eleven mutation hotspot regions were still identified. Phylogenetic analyses based on plastome data and the ITS sequences strongly supported that these three varieties were clearly distant from three type varieties. The results implied that these three varieties should be considered as three independent species, which were further justified by their multiple morphological characters. Therefore, revising these three varieties into three independent species was reasonable and convincing. Moreover, we also identified and described two new Sanicula species (S. hanyuanensis and S. langaoensis) from Sichuan and Shanxi, China, respectively. Based on their distinct morphological characteristics and molecular phylogenetic analysis, two new species were included in Sanicula. In summary, our study impelled the revisions of Sanicula members and improved the taxonomic system of the genus.
