Here's a flowering shoot from a different clone of Rosa multibracteata (source unknown) given to me in 1984 by Miriam Wilkins. Perhaps this is one of the "depauperate forms" E.H. Wilson wrote about in "Plantae Wilsonianae". Photographed June 22, 2011 at "Rose Woods" in the Mayacmas Mtns. near Petrified Forest, California.

Spectacularly living up to its name, "many bracts", here's a flowering shoot from a bush collected in 1988 at 1930 m (6332 ft) in Sichuan Province. Photographed at Quarryhill Botanic Garden, June 9, 2020.
