Your plant does not look to me like C. cardenasii; I vote it is a cross. > http://www.g6csy.net/chile/images/cardenas.jpg Wrong, and distorted, flower shape, but worse, really wrong calyx teeth. (These teeth look like C. pubescens or more likely C. eximium).. > http://www.fototime.com/94CE914D81B1F60/standard.jpg Leaves look too large for C. cardenasii, to me. > http://www.fototime.com/4916E90CA91BFFE/standard.jpg Looks like flower of C. eximium. > http://www.fototime.com/BD62B6C503EE24F/standard.jpg But this looks like C. cardenasii. If all these photos depict the same plant, I vote that it is a cross between C. eximium and C. cardenasii. --- Brent
