Elaeagnus pungens Thunb., belongs to the family Elaeagnaceae, was recently recorded for the first time in Mt. Miruk, Tongyeong-si, Gyeongsangnam-do. The native distribution range of this species includes China and Japan in East Asia, while it is considered as an invasive species in North America. Elaeagnus pungens is related to E. glabra, but the species can be distinguished from its congeners by having revolute and repand leaf blades, silvery white and brown scales on the abaxial surface of the leaf, and a campanulate calyx. We propose the new Korean name 'Tong-yeong-bol-re-na-mu,' based on its first collecting site. A detailed description of vegetative and floral characteristics, trichome scanning electron micrographs, dichotomous keys, and the habitat of this species are also provided.

어느 정도 연륜이 있는 분이라면 어릴 적 친구들과 함께 보리수나무의 붉은 열매를 맛있게 따먹던 추억을 간직하고 있을 것이다. 물론 덜 익은 열매를 서둘러 따먹어 떫은맛을 오랫동안 기억하시는 분들도 계시겠지만... 이렇게 우리나라에서도 보리수나무를 오래 전부터 식용의 목적으로 집 주변에 심어놓기는 하였지만 관상용으로는 그다지 많이 이용되지 않았다. 하지만 외국에서는 맛있는 열매 뿐 만 아니라 관상적인 가치를 높이기 위해 잎의 다양한 무늬종들을 선발하여 조경용 소재로 이용하고 있어 이에 소개하고자 한다.

The geographical distribution and soil characteristics of Korean Elaeagnus plants were investigated by literatures, field survey and soil analysis. Deciduous E. umbellata was distributed throughout the Korean peninsula including western and southern islands. Distribution area of evergreen Elaeagnus plants was classified into three groups; E. macrophylla and E. glabra belonged to group l occurring in the southern, western and eastern islands; E. submacrophylla to group 2 occurring in the southern and western islands; E. maritima and E. ankaii to group 3 in the southern islands only. Deciduous E. umbellata appeared euryeciously from poor soil to rich one, whereas evergreen Elaegnus plants appeared stenoeciously in haline soil near coast.

The taxonomic identity of Elaeagnus ×maritima and E. ×submacrophylla (Elaeagnaceae) in Korea is unclear, yet they are presumed to be hybrid taxa based on their morphology. To determine their hybrid origins, a morphological analysis (field surveys and specimen examinations) and a molecular analysis involving two nuclear ribosomal DNA (nrDNA) regions (internal transcribed spacer and 5S non-transcribed spacer) and one chloroplast DNA (cpDNA) region (matK) were conducted. The morphological analysis revealed that E. ×maritima showed certain morphological similarities to E. glabra, whereas E. ×submacrophylla showed certain morphological similarities to E. pungens. However, the molecular analysis indicated that E. ×maritima exhibited additive species-specific sites of E. glabra and E. macrophylla in the nrDNA regions. Notably, E. ×submacrophylla showed various aspects, with some individuals exhibiting additive species-specific sites of E. pungens and E. macrophylla in the nrDNA and E. macrophylla sequences in the cpDNA regions, some individuals exhibiting E. macrophylla sequences in the nrDNA and E. pungens sequences in the cpDNA regions, and some individuals displaying E. macrophylla sequences in both the nrDNA and cpDNA regions, despite an intermediate morphology between E. pungens and E. macrophylla. These results indicate that these two species are of hybrid origin and frequently cross between parental and hybrid individuals.
