임형탁,홍행화,김원기 한국식물분류학회 2006 식물 분류학회지 Vol.36 No.3

Prunus choreiana, invalidly published without Latin description in the original text, is validated here. The species has been known as a Korean endemic plant species of deciduous shrub, and a typical calciferous plant mainly distributed in Pyeongnam Province and Hamnam Province, North Korea. However, recently new population was reported from Mt. Myon and another new population is reported here from Mt. Jabyeong in Gangwon-do. 복사앵도나무는 벚나무속의 낙엽관목으로 우리나라 특산식물이다. 그러나 복사앵도나무의 학명은 라틴기재가 되지 않은 명칭으로 여기에 정당공표하였다. 복사앵도나무는 호석회식물로 북한에 한정되어 분포하는 것으로 알려져 왔는데, 최근 강원도의 면산과 자병산에서 새로운 분포지가 발견되었다.

임형탁,홍행화 한국식물분류학회 2007 식물 분류학회지 Vol.37 No.2

Saussurea nipponica subsp. higomontana was recorded first from Mt. Mudeung-san, Gwangju-si, Korea. We named the plant Mu-deung-chui. It had been considered as an endemic plant to Japan. S. nipponica sensu lato is the one of the most famous polymorphic species which consists of 7 infraspecific taxa (subspecies) isolating geographically. Among them, S. nipponica subsp. higomontana is distributed on high mountain regions of Kyushu and Shikoku. 광주광역시 무등산에서 취나물속의 1종인 Saussurea nipponica subsp. higomontana 를 발견하여 국명을 무등취로 명명하였다.

二家花樹木에 있어서 雌雄株間의 形態的 差異에 관한 硏究

任炯卓,崔明燮 건국대학교 1982 論文集 Vol.15 No.1

This work was investigated on the morphological differences between male and female of the dioecious planes. Morphological characters, mainly in shape of leaves of each male and female of some dioecious treed, are observed by naked eyes and stereoscopes. The results are following 1.In Populus tomentiglandulosa, the ratio of leaf size between a twig arid 2-year old branch of female tree is much greater than that of male. 2.In Populus euramericana, the color of petiole and a young leaf of female are reddish, but that of male is reddish and green. 3.In Slix pseudo-lasiogyne, the number of teeth of male is above 100 but that of female is below 100. Especially there are considerable instability of sexual condition in some male and female treed. 4.As for the color of upperside of petiole, the scarlet vestige of male is more ditinct than that of female in Salix graciliglans. 5.In Slix purpurea var. japonica, male has 1 or 2 lenticels below the basementof petiol but female has 3. And there are more than 5 lenticels on internode of female on the other hand male has leas than 3. 6.In matured Ginkgo biloba, the spur of male developes more vigorously than that of female and as for the bud of slur apex, male's is twice as large as female's.

태백취, 취나물속의 일신종

임형탁,이우철 한국식물분류학회 2007 식물 분류학회지 Vol.37 No.4

Saussurea grandicapitulata, a new species of Saussurea, was repodrted in the Taebaek Mountains. It has peculiar morphological characters, easily distinguisable from other Saussurea in Korea and Japan; robust plant size, pale green leaf beneath, purplish brown-cobwebby hairs on petioles of radical and lower cauline leaves, few heads with not so long pedicel, big globose involucres with brown-cobwebby hairs, and often recurved long phyllaries. S. grandicapitula is an endemic species to Korea which was differentiated in consequence of adaptation to heavy snowy environment of the Taebaek Mountains. 태백산맥에서 발견된 Saussurea속의 신식물을 태백취(S. grandicapitula)로 기재하였다. 우리나라 특산인 본 종은 크기가 70-100㎝에 달하는 장대한 식물로, 잎 뒷면이 창백한 녹색이며, 적갈색의 얽힌 털이 엽병에 나고, 수개의 두화가 짧은 화경에 달리며, 구형의 커다란 총포에는 갈색의 얽힌 털이 밀생하고, 포편은 뒤로 젖혀지기도 하는 특징을 가져서, 한반도 북부나 일본의 다른 종들과는 명확히 구별된다. 이는 태백산맥의 눈 많은 환경에 적응 진화한 종으로 생각된다.

Historic plant specimens collected from the Korean Peninsula in the early 20th century (I)

임형탁,손현덕,임재석 한국식물분류학회 2016 식물 분류학회지 Vol.46 No.1

Many of the historic plant specimens collected from the Korean Peninsula in the early 20th century deposited in herbaria in Korea were destroyed during the Korean War. However, duplicates of the specimens deposited in the Herbarium of the University of Tokyo (TI) remained unharmed. We examined historic plant specimens, identified undetermined specimens, and made a list to provide fundamental information on the early taxonomic history of Korea. One set of duplicate specimens was donated by TI and deposited into the Chonnam National Univer- sity herbarium (CNU) and into the herbarium of the National Institute of Biological Resources in Korea (KB).

임형탁,김규식,오병운 한국식물분류학회 2008 식물 분류학회지 Vol.38 No.4

Distribution of Carex miyabei Franch., formerly considered as an endemic species of Japan, in Korea is verified and reported here. It is distinguished from the morphologically similar species in the same section, such as C. lasiocarpa Ehrh. var. occultans (Franch.) Kük., C. drymopila Turcz. ex Steud. var. abbreviata (Kük.) Ohwi, and C. glabrescens (Kük.) Ohwi, in having long-beaked and acutely 2-toothed perigynia which are densely covered with stout short hairs. 국내에 알려지지 않은 융단사초(Carex miyabei Franch.)가 우리나라 중부 이남에 넓게 분포하는 것으로 확인되었다. 국내의 유사종으로는 벌사초(C. lasiocarpa Ehrh. var. occultans [Franch.] Kük.), 민숲이삭사초(C. drymopila Turcz. ex Steud. var. abbreviata [Kük.] Ohwi), 곱슬사초 (C. glabrescens [Kük.] Ohwi) 등이 있는데, 융단사초는 과낭 끝이 부리처럼 길게 발달하여 뾰족하게 둘로 나뉘며 짧은 털이 밀생하는 특징에 의해 이들과 구별된다.

임형탁,홍행화,손현덕,박명순,남보미,권보경,이철호,정규영 한국자원식물학회 2011 한국자원식물학회지 Vol.24 No.4

본 연구는 경상남도 지역에서 이용되는 민속식물을 파악하기 위하여 2009년 3월부터 11월까지 수행되었다. 17개 시(광역시)·군지역의 52개소에서 주민 60명을 대상으로 수집한 조사야장 293장의 설문조사를 분석한 결과, 경상남도 지역에서 파악되고 수집된 민속식물은 총 73과 157속 168종 2아종 11변종 1품종의 총 182분류군으로 정리되었다. 식용 129종류, 약용 41종류, 염료 3종류, 향료 2종류, 향신료 2종류, 관상용 2종류, 섬유 6종류, 유지 2종류, 기타 25종류로서 식용으로의 이용 빈도가 가장 높았으며, 이용 부위로는 잎, 전체, 열매, 뿌리 순으로 나타났다. This study was carried out to classify the regional folk plants in Gyeongsangnam-do. According to the survey results from 293 survey sheets of 60 residents at 52 places of 17 counties and cities from March to October, 2009, the folk plants in Gyeongsangnam-do consisted of a total 182 taxa; 73 families, 157 genera, 168 species, 2 subspecies, 11 varieties, and 1 form. The use by its usage was: 129 taxa; edible, 41 taxa; medicinal, 3 taxa; dye, 2 taxa; aroma, 2 taxa; spice, 2 taxa; ornamental, 6 taxa; fiber, 2 taxa; oil, 25 taxa; others, respectively, so the edible use was the highest. The most useful part was the leaf, followed by all parts, fruit and root.

고깔제비꽃, 왜제비꽃, 남산제비꽃 집단의 광조건에 따른 영양생장적 특징

임형탁 ( Hyoung Tak Im ),홍행화 ( Hang Hwa Hong ) 한국환경생물학회 2013 환경생물 : 환경생물학회지 Vol.31 No.4

임상의 동일 공간에 생육하고 있는 제비꽃속 세 종(고깔제비꽃, 왜제비꽃, 남산제비꽃)의 영양생장적 특징과 광량의 관계를 통해 각 종의 전략자적 특징을 알아보았다. 본 연구는 광주광역시에 위치한 무등산의 다섯개 지점으로부터 1994년, 1995년, 2000년에 중점 조사가 수행되었고, 2007년과 2010년 추가 조사가 진행되었다. 각 종의 집단 내 개체수의 변동, 개체의 건중량과 엽수, 조도에 따른 종의 분포 유형 분석을 통해 세 종이 임상의 광양에 의해 서로 다른 생태적 지위를 얻고 있음을 알 수 있었다. 고깔제비꽃은 K-전략자로서, 왜제비꽃은r-전략자로서, 남산제비꽃은 두 종의 중간에서 그 생태적 지위를 차지하는 것으로 해석되었다. In this study we investigated the relationship between characteristics of vegetative growth of three species of Viola (V. rossii, V. japonica, and V. dissecta var. chaerophylloides) and light in order to explain how these three species could live together under a closed space in a forest. This studywas carried out at five sites in Mudeung-san (Mt.) on 1994, 1995, and 2000 and additional investigations were performed on 2007 and 2010 at the same sites. In order to find the relationship, three main investigations were conducted: counting number of individuals for each investigated year, measuring dry mass and counting developed leaves per plant, and finding presenting patterns of each species with reference to incidence of light. As a result, we found that three species could share the closed space in a forest because of their different adaptive strategies like V. rossii as Kstrategist, V. japonica as r-strategist, and V. dissecta var. chaerophylloides as an intermediator between two species.

Report on the chromosome numbers of four Carex taxa in Korea (Cyperaceae)

정경숙,임형탁 한국식물분류학회 2019 식물 분류학회지 Vol.49 No.3

We report the meiotic chromosome numbers of four Carex taxa from Korean populations. Three are the first reports made on taxa from Korean populations: Carex appendiculata (Trautv. & C. A. Mey.) Kük. (n = 27 ), C. fernaldiana H. Lév. & Vaniot (n = 33 ), and C. metallica H.Lév. (n=15 ). Reports on the other species expand the range of variation in the chromosome number within a taxon, C. miyabei Franch. (n = 43 , 44 , 45 ). Carex L. (Cyperaceae) consists of more than 2,000 species worldwide and is the most species-rich genus in Korea. The species diversity in the genus has been hypothesized to be associated with the chromosome variation, but chromosome information pertaining to Korean Carex taxa is not well known. This report updates the chromosome number inventory on Korean Carex to 24 out of 180 taxa.

Chromosome number report of three Carex sect. Mitratae taxa (Cyperaceae) in Korea

정경숙,임형탁 한국식물분류학회 2020 식물 분류학회지 Vol.50 No.3

We report meiotic chromosome numbers of three taxa in Carex sect. Mitratae in Korea: Carex breviculmis R. Br. (n = 32 , 33 , 34 ), C. polyschoena H. Lév. & Vaniot (n = 37 38 ), and C. sabynensis Less. ex Kunth (n = 27 ). Section Mitratae is one of the most species-rich Asian groups in Carex, comprising approximately 45–80 taxa. Twenty-seven of these occur in Korea, and they are some of the most challenging taxa to identify due to their obscure and inconspicuous diagnostic characters. Including the counts reported here, half of the native Korean sect. Mitratae chromosome numbers have been documented. Their haploid chromosome num- bers range from n = 10 to n = 40, and many exhibit variations in the numbers counted within a taxon. These variations, along with the overall significant variation in sect. Mitratae, suggest that dynamic chromosome activity may be related to the high species diversity of Carex.
