l^ ins. long, to I in. wide ; simply toothed, quite free from down. Flowers 

 solitary at the end of short lateral branches, yellow at first, changing to 

 creamy white, 2 to 3 ins. across, opening the third or fourth week in May. 

 Calyx and flower-stalk smooth. Fruit globose, f in. diameter, nearly black 

 when ripe, and crowned with the sepals. 



There is some doubt as to the origin of this rose. It was at one time 

 called "yellow American rose," and Pursh included it in his Flora of N. 

 America. It has never been found wild in America, and all the later 

 authorities discard it. But its real native country is still not definitely known, 

 although it is generally believed to come from Siberia. It has been raised 

 from seed at Kew and come quite true, which w y ould appear to show that it 

 is not of hybrid origin. Some authors regard it as a variety of R. spinosissima, 

 and it is, no doubt, closely allied to that species, but is still so distinct in 

 habit and general appearance that it seems preferable to give it a separate 

 standing. It is one of the most lovely of single roses.

Native of W. China ; first raised at Kew in 1899, from seed sent to 

 England by Father Hugh Scallan (Pater Hugo), a missionary in its native 

 country. It is a most charming rose and the most vigorous of the yellow- 

 flowered species, beautiful even when not in flower, for its luxuriant, feathery 

 masses of foliage. It shares with R. sericea the distinction of being the
