Field work in Japan

Ryoko and her family romped though coastal and alpine pine forests of Japan to collect some more pine species, Pinus densifora, P. thunbergii, and P. parviflora, only found in eastern Asia. We drove around on the left side of the road to get to out-of-reach places. Thank you especially to Profs. Dai Hirose and Yousuke Degawa for their hospitality and help for collection permits.
