Description of R. ambiguum var. gonggaense: June 25, 2008 by Hans Eiberg
Leaves: ovate-lanceolate. Lamina 5-11 cm. long, 3-5 cm broad. Upper surface yellow-green, scaly, midrib not or fine hairy (difficult to see);
under surface yellow-green (0-1 years old leaves), scaly, the scales unequal, large and medium-sized yellowish with few light brown scales, contiguous
to their own diameter apart. The yellow-green backgrown is most pronounced on new growth. The matrix is a little glaucouos, but difficult to see
The leaves look and smell like R. concinnum (pseudoyanthinum), but the flowers are yellow.

West for Kangding we also found a population of plants with similar leaves, but here some of the flowers were more redish. We belived that these plants could be hybrids
between R. concinnum and R. ambiguum, but we found no R. ambiguum in the area.
But K. Cox wrote in his encyclopedia (version 1, p.340 line 8) that R. concinnum could not have yellow flowers, else it is a R. ambiguum.
