  • Fruit-discharge type of forty species of Asian Geranium were examined and their evolutionary trends and taxonomic system were discussed. Two main types of seed discharge in Geranium are made the basis of its divison into subgenera: Geranium subgenus Geranium, with a ballistic expulsion of the seed from mericarp, Geranium subgenus Robertium, with forcible discharge of the mericarp with the seed in it, separately from the awn. Variants of the seed ejecting type permit the division of Geranium subgenus Geranium into three sections. Section Ceranium, these has bristles at the base of the mericarp for prevent the seed from dropping from the divergent mericarp. Section Dissect, these has prongs at the base of the mericarp far prevent the seed from dropping from the divergent mericarp. Section Tuberosa, these has no bristles and prongs at the base of the mericarp, instead, retained of seed in pre-explosive interval by twist. Geranium subgenus Robertium was divided into two sections, Section Ruberta, with deeply wrinkled on the surface of mericarp at the time of discharge. Section Batrachioides, and section Trilopha, without wrinkle on the surface of mericarp at the time of discharge. According to the seed discharge, subgenus Geranium is thought to be more advanced than subgenus Robertium.

  • Cymopterus melanotilingia (Apiaceae) was reviewed by external morphology and cross-section of leaf-margin and mericarp, and the taxonomic position of species and genus was reexamined. Based on these results, the description and adistribution map of C. melanotiligia were obtained. The leaf-margin forms a collenchymatous ridge by projecting toward the lower part. One mericarp has 2-lateral ribs and 2-intermediate ribs and the other mericarp has 2-lateral ribs and 1-dorsal rib, suggesting each of them is asymmetric. These characters show that this species does not belong to the genus Ostericum s.s., but should be treated as the genus Cymopterus.

  • Sophisticated modern research tools for evaluation of medicinal plants are available but microscopic methods are one of the simplest and cheapest methods to establish the identity of the source materials. Pharmacognostical investigation of the dried, powdered and anatomical sections of the fruits of Trachyspermum roxburghianum (DC) Craib was carried out to determine its macro and microscopical characteristics along with its physical constants. Externally, the fruits, yellowish or greenish brown in colour are elongated, elliptical, slightly curved, prominently ridged and longitudinal. As seen in transectional views of the fruits from Trachyspermum roxburghianum, the mericarp has concave sides called commissural surfaces and a convex outer side called the dorsal surface. The mericarp has three primary ridges alternating with two secondary ridges on the dorsal side. On the commissural side, there are two primary ridges which are lateral in position and two secondary ridges in the commissural side. The seed is attached to the pericarp by a short stalk called a raphe. Circular, four-lobed calcium oxalate crystals are fairly abundant in the endosperm. Phytochemical studies revealed the presence of phenolic compounds, triterpenoids, proteins and sugars. The pharmacognostical profile of the fruits will assist in standardization for quality, purity and sample identification.

  • Background : As the characterization of medicinal plants is an important aspect of traditional Asian herbal medicine, this study examines the morphological and anatomical characteristics in four fructus form medicinally important plants belonging to the family Apiaceae. Methods and Results : Fruit morphology of four genera was examined using microtome sections and light microscopy. The Anethi Fructus, Anethum graveolens (Siraja) has unique wing-like and membranous lateral ribs that are, approximately $500{\mu}m$ wide. The Coriandri Fructus, Coriandrum sativum (Hoyuja) does not have oil ducts at the dorsal region of the mericarp and differs in the development of the dorsal ribs. The ribs appear upon drying and therefore, consist of primary and secondary ribs. The Foeniculi Fructus, Foeniculum vulgare (Hoehyang) characteristically develops three dominant dorsal ribs and has a strong aromatic fragrance. Finally, the Cnidii Fructus, Torilis japonica (Sasangja) has many oil ducts at the dorsal and carpophores regions and develops many hooked trichomes one the fructus surface. Conclusions : We conclude from this study that each plant has several prominent and distinguishing morphological and anatomical characteristics. Therefore, fruit morphology is very useful for identifying these medicinal plants. In addition, the correct use and herbal name need to be standardized for plants used traditionally in Asian medicine within Korea, China, and Japan.

  • Compare to investigate the taxonomic utility of infragenera system and interspecific of Asian Geranium, we examined the fruit and seed morphology from 35 taxa. The fruit shape and seed's dispersal way did so that may divide subgenus or some part section to do could reason evolutionary trends. That is, at seed dispersal, the awns of section Geranium of subgenus Geranium, ramains attached at the top of rostrum, though fairy easily broken off, because seed increases awn's elasticity by diffusive way, it is long characteristic seed\`s dispersal distance, and subgenus Robertium observed that seed dispersal distance is short because it is no awn's elasticity by way that seed dispersal is gone as awn drops with rostrum. Also, section Geranium of subgenus Geranium and subgenus Robertium act role that awn keeps temporarily breed swerving with mericarp instead of bristle because section Tuberosa of subgenus Geranium is not bristled function that keep temporarily breed because mericarp bristled on base at seed dispersal do while. Therefore, is thought that is talon that when consider formation's development and function regarding this seed dispersal function, subgenus Geraniuum evolves more than subgenus Robertium. Seed morphology can divide by 2 subgenera(Geranium, Robertium) according to pattern of seed coat. and Seed's morphology characteristic(whole shape, color, form of seed apical and base, micropyle area, hilum area, chalaza, and position of seed hilum area), can distinguish some species, but is thought that is not reasonable as for discernment characteristic form and nature by repetition of characteristic form and nature. Especially, infrasection do in fruit and seed's morphology that is handling in this research that know to argue classification system and relationship by repetition of characteristic form and nature difficult. To all reliable truth, cytological, ecological, embryology, and molecular genetics research about talon is considered that should be achieved section Geranium that do not handle yet.

  • The systematic position of Cymopterus melanotiligia (H. Boissieu) C. Y. Yoon in Apiaceae was revaluated based on the ITS sequence data. Its diagnostic characteristics include its asymmerty mericarps, 3-4 mericarp ribs, winged dorsal ribs, and ternate leaves. It is morphologically similar to Tilingia tsusimensis and Pimpinella having ternate leaves. It is distinguished from Ostericum having symmerty mericarps, 5 mericarp ribs, and rounded dorsal ribs. Also it looks like Angelica with broadly winged lateral ribs and strongly dorsally compressed mericarps, but is distinguished by having its conspicuous calyx teeth and unilayer pericarps. Cymopterus melanotiligia formed a different clade group with Cymopterus species distributed in North America based on ITS sequences, and it supports the close relationships with Halosciastrum melanotilingia. Thus, we conclude that this species is here referred to Halosciastrum melanotilingia (H. Boissieu) Pimenov & Tikhomirov.

  • Richardia brasiliensis Gomes was found in agricultural land in Susan-ri, Seogwipo-si, Jeju-do. Richardia L. is closely related to Diodia L. in Korea, those are confirmed to features of calyx, collora and fruit. This species is similar to R. scabra L., but it differs morphologically from the letter in surface structure of mericarp. The mericarp of R. brasiliensis has line like kneel at the adaxial, whereas R. scabra has groove at the adaxial. R. brasiliensis is recorded for the first time in this study and a morphological description, distribution map, and photographs are presented.

  • It was revaluated about taxonomical position of the Tilingia tsusimensis (Yabe) Kitagawa (Apiaceae) collected from Mt. Gaya, Mt. Geumo, and Mt. Songni in Korea. Its diagnostic features include slightly dorsally compressed mericarps, acute-prominent ribs, ternate leaves, and dimorphic white petals. It is morphologically similar to Cymopterus and Pimpinella in having ternate leaves. It is distinguished from Cymopterus having asymmerty mericarps, 3-4 mericarp ribs, and winged dorsal ribs. Pimpinella differs in having slightly laterally compressed mericarps without ribs and conspicuous calyx teeth. Also, it looks like Angelica with obsolete calyx teeth and multilayer pericarps, but is distinguished by having its broadly winged lateral ribs and strongly dorsally compressed mericarps. Tilingia tsusimensis formed a monophyletic clade or sister group relationship with a genus Angelica based on ITS sequences. Based on the above observations, we conclude that this plant is here referred to T. tsusimensis (Yabe) Kitagawa.

  • This study was conducted to obtain the basic data related to seed characteristics and germination conditions of the Coriandrum sativum L. at different storage condition and temperature. The shape of fruit was oval with light brown color. Fruit was mericarp, biloculate, with one ovule in each locus. The length and width of seed were $1.37{\pm}0.067mm$ and $0.52{\pm}0.039mm$, respectively. Weight of 1,000 seeds was $6.55{\pm}0.15g$. Seeds which were stored at room ($15^{\circ}C$) and cold temperature ($4^{\circ}C$) in vinyl container showed the highest germination rate (93.3%) under the room temperature germination condition. Percentage of germination in cold and freeze temperature was 20% and 0%, respectively. Germination rate of room storage seeds with paper container increased to about 91.3%, however, decreased in cold ($4^{\circ}C$) and freeze storage ($-20^{\circ}C$) with paper container (76.7% and 78.0%, respectively). Germination rate of seed in vinyl stock container was better than that of paper stock container. Germination rate of seeds stored at room temperature for 4 years (2010 - 2013) ranged from 80.0% to 91.3%. Therefore, coriander seeds are expected to be stored at room temperature for increasing the germination rate and keeping a long term.
