“…In previous studies on this species, either simple descriptions, such as, "The overall size is smaller compared to I. textorii", "The spur is long and not coiled" and "The flower is white", were recorded (Park 1974;Lee 1996) or only the plant list without a description or diagnosis was recorded (Chung et al 1937;Park 1949;Chung 1956;Lee 1980;Lee 2006). Ji et al (2010) later re-assessed the taxonomy and morphological characteristics of I. furcillata, based on the original description and type materials. They recognised many characteristics that distinguish this species from other Korean Impatiens species, including the glabrous stem, drooping peduncle, pinkish-white flower, ovate-oblong leaf blade and non-coiled, biparted spur tip.…”

A new species Impatiens hambaeksanensis from Gangwon-do, South Korea, is described and illustrated, based on its morphology and distribution. I. hambaeksanensis is different from I. furcillata, another similar Impatiens species in South Korea, in some ways: I. hambaeksanensis possesses a serrate leaf margin with flat tooth tip, while I. furcillata possesses a crenate leaf margin with erect tooth tip; it has an erect inflorescence, while I. furcillata has a pendulous inflorescence; it has a smaller flower which is 2–2.6 cm long, while I. furcillata has a flower of 2.3–3.2 cm; the flower is white or pinkish-white with yellowish and purplish spots, while I. furcillata has a white lower sepal and pinkish-white lateral united petals with yellowish spots; the distal part of the lower sepal is mostly not coiled or rarely 1-coiled, while that of I. furcillata is never coiled; the spur tip is expanded, round and slightly biparted, while that of I. furcillata is expanded, ellipsoidal and clearly biparted. A taxonomic description, a holotype and photos of morphological characteristics of the new species are provided. A table which includes the morphological comparison and a geographical distribution map are presented as well.

“…Consequently, I. kojeensis and I. hypophylla var. koreana were treated as synonyms of I. furcillata and the Korean name of I. furcillata was changed to "Cheo-jin-mul-bong-seon" (Ji et al 2010).…”

“…Impatiens is morphologically classified according to the color and shape of the flower, the shape of the spur, and the shape of the leaf. Impatiens furcillata is distinguished by the characteristics of a small flower, a light pink color, and by the fact that it droops downward without curling (Ji et al, 2010).…”

An effective pollinator was investigated based on visiting insects to confirm the pollination mechanism of Impatiens furcillata Hemsl. (cheo-jin-mul-bong-seon), an annual herb that is also a species endemic to Korea that has hardly been studied in relation to pollination ecology. The insects that visited the group of I. furcillata studied here consisted of four orders, 11 families, and 16 species; Hymenoptera had seven species (43.8%), Lepidoptera had four (25.0%), Diptera four (25.0%), and Hemiptera one (6.2%). Visiting insects were divided into those that took only nectar, those that took nectar and pollen, and those that took neither. Insects that are effective for pollination are judged considering the length and body type of their mouth parts, and Amegilla florea Smith (huin-jul-beol) is judged to be the most effective pollinator in the survey area. As a result of observing pollination behavior, when visiting a flower, A. florea, which extended its glossa, approached the front, landed on a wing petal of I. furcillata, crawled into the flower tube, and then backed up and reversed its steps, with pollen adhered to its back. The findings here present basic information about species biology related to both I. furcillata and A. florea.

We investigated the flora of Jang-do (Isl.), an island of the Heuksan archipelago, located in Heuksan-myeon, Shinan-gun, Jeollanam-do and discussed the remarkable plants found there. Thirteen-field trips (total 27 days) were completed from May of 2004 to May of 2013. As a result, we identified the distribution of 423 taxa in Jang-do (Isl.), comprising 104 families, 285 genera, 335 species, 78 varieties and 10 forms. There are a total of 95 taxa of floristic regional indicator plants. The floristic regional indicators are as follows; four taxa of level V such as Impatiens furcillata, four taxa of level IV such as Hosta yingeri, 14 taxa of level III such as Ophioglossum vulgatum, 5 taxa of level II, and 58 taxa of level I. In addition 10 red data plants, 2 vulnerable species (VU) including Calanthe striata for. sieboldii, and 4 least concern species (LC) like Ardisia crenata, 2 not evaluated species (NE) such as Hosta yingeri, were found in the investigated area. An unrecorded species, Fragaria (Rosaceae), was found in a forest of Jang-do (Isl.) for the first time in Korea.
