경상북도 울릉군에서 바늘꽃과 바늘꽃속의 신종인 울릉바늘꽃(Epilobium ulleungensis J. M. Chung)을 발견하여 기재 및 도해하였다. 울릉도에 분포하는 바늘꽃속 4분류군(바늘꽃, E. pyrricholophum; 돌바늘꽃, E. amurense subsp. cephalostigma; 큰바늘꽃, E. hirsutum; 울릉바늘꽃, E. ulleungensis)중에서 울릉바늘꽃의 주두는 4각형으로서 곤봉형인 바늘꽃 또는 두상형인 돌바늘꽃과 4개로 깊게 갈라지는 큰바늘꽃의 중간 형태를 보이고 있다. 중요하게도, 울릉바늘꽃은 200 cm 이상의 큰 키와 비스듬히 누운 줄기, 잎의 형태, 식물체 전체의 짧은 밀모, 그리고 꽃의 크기와 진분홍색 또는 붉은 자주색의 꽃 색은 울릉도에 분포하는 다른 3분류군과 명확하게 구별된다. 주두의 형태와 다른 분류학적 형질들에 의해 울릉바늘꽃은 큰바늘꽃과 바늘꽃 또는 돌바늘꽃과의 잡종으로 추정되었다. 신종의 자생지가 울릉도인 점을 고려하여 'ulleungensis'이라 신칭하였다.

A new species, Epilobium ulleungensis J. M. Chung (Onagraceae Juss), from Ulleungdo Island (South Korea) was described and illustrated. Among four taxa native to Ulleungdo Island (E. amurense Hausskn. subsp. cephalostigma (Hausskn.) C. J. Chen, Hock & P. H. Raven, E. hirsutum L., E. pyrricholophum Franch. Sav., and E. ulleungensis), E. ulleungensis has a unique tetragonal stigma, which is considered to be an intermediate form between clavate (E. pyrricholophum) or capitate (E. amurense subsp. cephalostigma) and 4-lobed stigmas (E. hirsutum). More importantly, this new species is clearly distinguished from the other three taxa distributed on Ulleungdo Island by its height (over 200 cm), decumbent stem, leaf shape, short, dense pubescent covering on the whole plant, large flower size, and a dark pink or red purple flower. According to the stigma shape and other characters, it was estimated that E. ulleungensis is a hybrid between E. hirsutum and E. pyrricholophum or E. amurense subsp. cephalostigma). The specific epithet "ulleungensis" was chosen because the new species was restricted to Ulleungdo Island.

2). Other characteristics (such as height over 200 cm, relatively short [7.9.9.5 cm] lanceolate to long elliptic leaf shape, dark pink or red purple petal, and loosely villous pubescent surface) were distinguished from E. hirsutum (Table 1, Figs. 1, 2). According to the stigma shape and other characters, it was conjectured that E.
