Kakayan-Bara (Cagayan Rose) syn. =Yaeyama-No-Ibara (Field Briar from Yaeyama Islands)
R. bracteata J.C.Wendl.
Bot. Beob.:50 (1798)
This rose is found only in some of the Yaeyama Islands, which are located in the southern points of Japan, but also is distributed in lowlands of Taiwan and southern areas of China. The author saw it growing wild in grassland on Ishigaki Island.
In 1828, a drifting ship reached the coast of Cagayan, northern part of Luzon Island, the Philippines. When the sailors came back to Japan two years later, the captain brought seeds of R. bracteata to Daisuke Baba, a samurai and a famous plant collector. It was the first record of this rose in Japan, and so it came to be called Kakayan-Bara.
It gives pretty large white flowers 5 to 7 cm across. Notched bracts just below the calyx tube are the distinctive feature of this rose. A famous descendant of this rose, 'Mermaid' (W. Paul, 1918) has bracts of the same shape, too. The author heard that R. bracteata comes in bloom in May in its natural habitats, but the one she planted in Chiba (near Tokyo) gives flowers sporadically from May to November...
