Jim: I have grown Lilium rosthornii from a Species Lily Preservation bulb sale. It has flowered very well here planted under a Chinese Quince ( Pseudocydonia sinensis). Only way to tell it apart from lilium henryii is the shape of the fruit. L. rosthornii has a long oblong capsule and L. henryii is oblong. L. rosthornii is found in Sichuan, Hubei and Guizhou, L. henryii from Hubei, Jiangxi and Guizhou. I posted the image on the Wiki Wiki of L. rosthornii. http://pacificbulbsociety.org/pbswiki/files/… Arnold NJ
