Note：
A. subvirens has been found that symbiotic associations among Castanopsis Spach., Quercus L., Lithocarpus Bl.. Horak (1980) had predicted that this species should happen in China according to its ecological surroundings. So it was known from China (Zang, 1985). Now it extends southward to the central part of Taiwan.
