Chloroplast genomes of two morphologically similar species, Viola selkirkii and V. ulleungdoensis, were compared. For this comparison, three individuals of V. selkirkii from Ulleung-do Island (UE), Jeju-do Island (JJ), and Hwacheon-gun (HC) and one of V. ulleungdoensis from UE were collected. According to chloroplast genome sequencing of V. selkirkii and V. ulleungdoensis, their genomes were found to contain 156,774-157,454 and 157,575 bp, respectively, and a total of 111 genes. In the comparison of the three V. selkirkii individuals, V. selkirkii obtained in UE was distinguished from those of the other regions of HC and JJ, and in the comparison of the three V. selkirkii individuals and one V. ulleungdoensis individual, V. selkirkii obtained from UE and V. ulleungdoensis were distinguished from the species in the other regions. In addition, a phylogenetic analysis revealed that 32 taxa of Viola formed a monophyletic group (bootstrap support [BS] = 100). The four Viola individuals used in this study (three V. selkirkii and one V. ulleungdoensis) formed a monophyletic group (BS = 100), which was further divided into two subclades. One subclade comprised V. selkirkii found in UE and V. ulleungdoensis, whereas the other subclade comprised V. selkirkii found in HC and JJ. These results support the view of prior studies that V. selkirkii growing in UE and V. ulleungdoensis are the same species.

울릉도에서 제비꽃속의 신종인 울릉제비꽃(Viola ulleungdoensis M. Kim & J. Lee)을 새로이 발견하여 기재하였다. 분자생물학적인 결과는 울릉제비꽃이 근연종들과 구별되는 신종임을 지지해 주었다. 울릉제비꽃은 무경종이고 측화판 기부에 털이 없으며 엽병과 화경에 털이 없어 뫼제비꽃과 유사하다. 그러나 울릉제비꽃은 부정아가 없고 개화 후 잎이 커지며 식물체가 크고 저지대에서 자라는 반면에, 뫼제비꽃은 부정아가 있고 개화 후 잎이 커지지 않으며 식물체가 작고 고지대에서 자라 두 종이 뚜렷하게 차이가 난다.
