Question
Hello again Ace Botanist Sir... Sent some photos of a native rose yesterday for identification. Have been looking at the desrctpitions for clues but still condfounded so here are some addtional pictures with greater detail that might help if more detail is required... The excessive pricklyness of the stems is leaning me towards Rosa acicularis — bristly rose Cheers
Answer
Dear pmhood, good morning to you. What I can write to you is that this is not Rosa palustris. That species would have stalked glands on the hypanthium surface (below the sepals), similar to other members of the Rosa virginiana complex. It does not look Rosa acicularis (that species is quite glandular on vegetative surfaces, such as the stipules, which I cannot observe in your images). The leaflet blade shape reminds me of Rosa blanda, but I would expect fewer prickles on the stems/branches for that species (though some specimens do show prickles like what you have photographed here). I would like to help you further with this, but it might require a conservation. Contact me at ahaines@nativeplanttrust.org and we will determine what species you have photographed. Best wishes.
