PhytoKeys:doi: 10.3897/phytokeys.@.32270
Abstract
Petrocodonrubiginosus Y.G. Wei & R.L. Zhang, sp. nov.,
from Guangxi of South China, is described and illustrated with photographs. The
new species is morphologically similar to Pet. hechiensis, but can be
easily distinguished by a combination of characters, especially in its
petioles, peduncles and pedicels covered with densely ferruginous pilose hairs.
