  • The petiole anatomy of three sections (sects. Calospira, Chamaedryon, and Spiraria) in the genus Spiraea (Rosaceae), which are distributed/cultivated in Korea, was studied and described in details. The vascular bundle system of the distal, medial, and proximal parts of the petiole were studied using LM with the aim of documenting any differences in vascular anatomy. Significant variation of anatomical characters was found in petiole shape (dichotomy, lens or subcircular in outline), presence of two distinct lateral wings, the thickness of epidermis, number of vascular bundles, length of ventral axis, length of dorsiventral axis, width of median vascular bundle, and length of median vascular bundle. All features were compared and we concluded that petiole anatomical characters can be useful for providing diagnostic features to distinguish the studied taxa. A key for identifying the Spiraea taxa in Korea based on their petiole anatomical characters is also provided.

  • The bipinnate-compound leaf of Parkia clappertoniana has prominent, long petiole with a pulvinal base. The pulvinus has wood, periderm, lenticels and extensive cortical layer. Its vascular bundles are elongated with alternating rays. The vascular bundles of the petiole, rachis and veins are oval, with conspicuous bundle caps. Stomatal complex is predominantly paracytic with occasional occurrence of anomocytic stomata near the midrib. The oval stomata have conspicuous stomatal ledges. Trichomes are unicellular, acicular and restricted to the rachis, petiole and pinnule mid-ribs and margin. Ecological and taxonomic significance of features is discussed.

  • A comparative study of the petiole anatomy in the tribes Forsythieae (Abeliophyllum, Forsythia) and Fontanesieae (Fontanesia), including one related genus Myxopyrum belonging to Myxopyreae, was carried out using light microscopy. The anatomical characteristics of the distal, medial and proximal parts of the petiole were studied to document any differences. We are described in detail based on their quantitative and qualitative characteristics. Three crystal types (acicular, druse, and prismatic crystals) were found in both Fontanesia and Myxopyrum within all of the studied taxa. Uni-cellular non-glandular trichomes were found in Abeliophyllum and three Forsythia taxa (F. europaea, F. giraldiana, and F. japonica). All features were compared and the vascular patterns of the petiole were distinguished in two types: Type 1A: Trace continuous arc - without crystals (Abeliophyllum, Forsythia), 1B: with crystals (Myxopyrum), Type 2: Trace invaginating at ends with crystals (Fontanesia). A detailed anatomical description of the studied taxa is provided, and its systematic importance is also briefly discussed. In conclusion, some petiole anatomical characteristics (e.g., the main vascular patterns, the presence/absence of crystals) can be useful for diagnostic features as well as partly for supporting the recently proposed molecular phylogeny.

  • This study was intended to identify 17 taxa. (5 varieties and 12 species) of the genus Acer in Korea on the basis of the shapes of stomata, the type of trichome on the different part of leaves, the shapes, arrangement and number of stele in cross section of petiole. The results obtained were summarized as follows; 11 The shape of guard cells of stomata in the genus Acer was anomcytical, and the size of the cells ranged from 10.25 to $21.00{\mu}$ in length and from 7.57 to $11.83{\mu}$ in width. 2) Eleven types of trichome on the leaf in the genus Acer were found; pilose, sericeous, velutinous, woolly, glabrate, puberulent, bladder hair, hispid, hirsute and uncinate. This characteristics also established a good criterion for identification of species. 3) The stele of petiole in the genus Acer was characterized by eustele and atactostele with polybranch, and the six groups of the shape of numerical change of stele; B>M=T, BM

  • Objectives : The goal of this paper is to research what affected diagrams of liver originated from Mingtangzangfutu while they were changed. Methods : Diagrams of liver in Traditional Chinese and Japanese medical books had been gathered as many as possible. After they were divided into ones which were originated from Mingtangzangfutu and the others, diagrams originated from Mingtangzangfutu, were again classified into 4 filiations according to Huang Longxiang(黃龍祥)'s standard. Apart from his classification, they were analysed by 4 form factors, e.g. shape, number, veins and petiole of leafs. Results : Reliability of this methods had been confirmed by the correspondence with Huang's 14 standard books, before 29 diagrams of liver were derived from 33 books including 13 books that Huang had already suggested. The lobes of liver in most of diagrams resembled 7 lanceolate or long oval leafs, or a maple leaf with 6 indentations, 4 left lobes and right 3 ones. In most of diagrams, veins of leafs were described variously, and petioles of leafs were drawn more shortly or longer. Analysing 29 diagrams by 4 form factors proved that Huang's classification had crossing features among 4 filiations. This phenomenon implied the painters or doctors drawing diagrams might not convince if the shape of liver was correct or not. Although veins and petiole of leafs in diagrams of liver could be compared with tissues in liver in modern human anatomy, diagrams were not been affected by dissection from Yuan(元) to middle Qing(淸) dynasty. Conclusions : Lingshu(靈樞), Nanjing(難經) and Wang Bing would had constantly acted on 29 diagrams of liver, since diagram of liver originated from Mingtangzangfutu, appeared first in Zhenjiujuying(鍼灸聚英). But they did not come from dissection during same periods.

  • Examined were the vegetative and reproductive characters such as external morphology, anatomy (leaf petiole, blade and stem), pollen and nutlet for the taxonomic revision of Elsholtzia in Korea. The inflorescence of all studied taxa of Elsholtzia in Korea is secund and 0.5-10 cm long. Leaves are ovate or nearly and $0.2-10{\times}0.2-6.0cm$. The shapes of inflorescence and leaves are very useful taxonomic characters. The stomata types are anomocytic and diacytic. The morphology of nutlet is ovoid and pitted in surface pattern of exocarp. All studied taxa are myxocarpy. The pollen grains are of medium size and subprolate in shape, and have typical bi-reticulate exine surface. Four species are recognized for Korean Elsholtzia by the identification key and descriptions in this study.

  • Two anatomical features of leaves, transverse section of midribs and petioles, were examined for nine species of five genera of Thymelaeaceae, Daphne L. -4 spp., Diarthron Turcz. -1 sp., Edgeworthia Meisn. -1 sp., Stellera L. -1 sp., Wikstroemia Endl. -2 sp., using light microscopy and scanning electron microscopy. In terms of shape of upper side, three types were observed, i.e., flattened, depressed, and raised. Outline of petioles is mostly semi-circular or circular in transverse section, with two distinct wings/weakly developed wings or without wings. Other characters besides anatomical features of leaves such as vascular bundle tissues, crystal, tannin are also described in details. Finally, we briefly discussed the systematic significance of the anatomical features of leaves for identification of Korean Thymelaeaceae.

  • Objectives : Saururus chinensis and Houttuynia cordata (Saururaceae) are perennial herbs using for medicinal purposes in Korea. The objectives of this study are to compare anatomical key characters between two medicinal plants and to provide fundamental information for the identification of two herbal medicines by using anatomical features. Methods : Cross-sections of root, rhizome, stem, petiole, and leaf for each species were observed in this study. Materials were analyzed through dehydration, paraffin embedding and micro-sectioning, and double staining with Safranin O and Fast-Green FCF. Observations of permanent preparation were conducted using light microscope. Results : S. chinensis and H. cordata were distinguished with anatomical differentiations; Idioblasts with essential oil were scattered in the parenchyma cell of cortex, pith, and phloem of S. chinensis, on the other hand, in H. cordata, idioblasts were distributed ring-shaped in the cortex of the root. S. chinensis had two cycles of vascular bundles in the stem while H. cordata had one cycle. Hypodermis layer was conspicuous in a stem of H. cordata, crystals were observed the only parenchyma in a stem of S. chinensis, and epidermal oil cells were developed in the epidermis of H. cordata. S. chinensis had air cavity at the cortex and pith of the stem. The shape of cross-section was polygonal in the stem of S. chinensis and was circular in the stem of H. cordata. Conclusions : We investigated anatomical study of Korean S. chinensis and H. cordata. To identify two herbal medicines, we considered main anatomical features and provided identification key here.
