Rosa spinosissima , var. hispida is a yellow-flowered variety nearly 
allied to var. ochrolenca . It was growing in 1813 in the Physic Garden 
at Chelsea, where it had been established for many years. A specimen 
preserved in Sir Joseph Banks’ herbarium was gathered in Dr. 
Pitcairn’s garden at Islington as far back as 1781. There is a good 
drawing in the Botanical Magazine. From its being called the 
“Yellow American Rose” Pursh was led into the mistake of including 
it in his F lora of N orth America. 1 1 onlydiffersfrom Rosa spinosissima , 
var. altaica in the sulphur-yellow colour of its flowers. Its fruit does 
not differ from that of the typical Rosa spinosissima L. It comes 
true from seed. 
The specimen from which our plate was drawn is somewhat off 
type in the armature, which should be like that of the type.
