I visited the (Quelpart) island in 1933 and observed that the tree, which was growing wild, showed differences from P. yedoensis; the hairs on calyx lobes and on the lower side of leaves were less numerous, and the peduncles were shorter. I concluded that it could not be P. yedoensis. I assumed that it might be a hybrid between P. subhirtella var. pendula form ascendens (Edo higan) and Prunus quelpaertensis (Tanna-yamazakura; perhaps a form of P. verecunda) or some other cherry species
natural hybridization either in the Izu peninsula, on Izu-oshima Island or on Cheju-do Island in Korea, although the possibility of the latter location was ruled out by Takenaka (1962)
The nuclear (ITS/ETS and G3pdh) and cpDNA data, along with several morphological characteristics, provide the first convincing evidence for the hybrid origin of wild P. yedoensis. The maternal parent was determined to be P. spachiana f. ascendens, while the paternal parent was unresolved from the taxonomically complex P. serrulata/P. sargentii clade.

여의도와 진해를 포함해 우리나라 벚꽃축제의 주인공은 모두 일본이 원예종 으로 만든 왕벚나무이다. [The protagonists of Cherry Blossom Festivals in Korea including Yeouido and Jinhae are all cultivated Yoshino cherry made in Japan.]
당시까지 왕벚나무라는 우리말 이름은 없었고, 사쿠라나무, 털벚나무 등으로 불렸다. 도봉섭, ｢조선산식물의 분류 (中)｣, 「동아일보」 1936. 4. 21. [Until then, there was no Korean name for king cherry, and it was called sakuranamu (sakura tree), teolbeonnamu (hairy cherry tree), and so on. Do Bong-seop, "Classification of Korean Plant (Second)", "Dong-A Ilbo" 1936. 4. 21]
To me P. yedoensis Matsumura strongly suggests a hybrid between P. subhirtella, var. ascendens Wilson and the wild form of P. Lannesiana Wilson. It has many characters of the latter and in its venation, pubescence and shape of the cupula resembles the former.

제주도 왕벚꽃이란 이름도 오래된 것은 아니다. 육지학자들이 현지 답사에 나선 1963년도에 처음으로 지은 것이라 한다. 그때까지는 '털벚나무'나 '사쿠라'로 표기하고 있다. [The name "king cherry" is also not old. It was named in 1963 for the first time when scholars conducted a field survey. Until then, it was called "hairy cherry" or "sakura".]
Wild cherry trees which grow wild in Mt. Halla and whose blooming season is April are mostly P. subhirtella var. pendula form. ascendens and P. donarium P. yedoensis is rare in number, around 10 individuals, having been found in a half century.
Prunus × yedoensis Matsumura, Rosales: Rosaceae, Prunus × yedoensis is a deciduous tree endemic to Korea that only about 5 populations occur at Mt. Halla in Jeju-do. The estimated number of individuals is very small. This species is found in deciduous broadleaf forests at 450-900 m above sea level. The species is assessed as EN B2ab(iv). There are currently no regional conservation measures.

A remarkable result is that the P. yedoensis wilds from Jeju ended up far from the P. yedoensis cultivars, as was proposed in a previous study based on random amplified polymorphic DNA (RAPD).
The two natives of P. yedoensis from Jeju, Korea were clearly distinguished from the cultivars as suggested in previous reports.
The idea that P. yedoensis Matsumura-Native would be different from the P. yedoensis Matsumura-Cultivar would be strongly substantiated from the similar results obtained in this studies with those of previous studies.
... From 1966 until the mid-1980s, Koreans in Japan and Japanese people donated about 60,000 cherry seedlings to Jinhae City.
