ACKNOWLEDGEMENTS
NW Sichuan in 1988 and 1989, and Dr PEI Yan-Long, now in Canada, made trips to Shanxi and
W Hubei in 1991, 1992 and 1993.
In our expedition to Henan in 1994, the late Prof. WANG Shui-Yi and Dr WANG Yin-Zhen
formerly from Henan Agricultural University (now in our laboratory) were members of the team.
Dr HE Yong-Hua from the Chengdu Institute of Biology, assisted our expedition to NW Sichuan
in 1995 and Dr ZHANG Shu-Ren in our laboratory joined our expedition to Tibet in 1996.
Prof. YE Yong-Zhong from Henan Agricultural University, Dr FENG Yu-Xin (my former Ph.D
student now in the USA) and I made a field trip to W Hubei, W Henan and Shaanxi in 1997, which
was assisted by Mr DAI Zhen-Neng at the Bureau of Forestry of Baokang County, Hubei. At the
same time, PAN Kai-Yu and Dr XIE Zhong-Wen, now in the USA, made a field trip to Anhui
Province. In 1998, Mr LOU Lu-Huan helped us in our trip to Mt Tianmu in Zhejiang, and Dr CAO
Wei assisted us in our expedition to NE China.
I did field work in Idaho in 1999 with the assistance of Dr Jenny Q. Y. Xian (now at North Carolina
State University). In 2005, PAN Kai-Yu and I made a field trip to western N America. Assisted by Dr
QIU Jun-Zhuan, we observed and sampled two populations of P. californica near Los Angeles. Miss
P. Woodward organised a trip to the Blue Mountains in Oregon and Washington states, where we
observed and sampled three populations of P. brownii.
We made several field trips in 2004. Prof. REN Yi, from Shaanxi Normal University, assisted our
expedition to Mt Taibaishan in Shaanxi. Dr ZHOU Zhi-Qin, of Southwest University, and Mr
YANG Shi-Xuan joined our trip to Mt Shennongjia in W Hubei. Mr CAO Rui, at Inner Mongolia
University, and Dr YANG Fu-Shen and Miss PENG Dan, of our laboratory, assisted our expeditions
to Inner Mongolia. Mr ZHANG Hong-Yue and Mr CHEN Yan, of our laboratory, joined our
several expeditions to NE China, Hebei, Henan and Inner Mongolia.
Miss LI Er-Li made the pencil and ink drawings, whereas Miss CAI Shu-Qin and Mr SUN Yin-
Bao drew the ink drawings for this monograph. All the scanning electron microscope photographs
were taken by Mr XIAO Yin-Huo and developed by Mr YANG Xue-Jian. Miss LI Qiao-Ling,
my former secretary, helped a great deal with office work and in the preparation of articles and
applications for grants.
To all the persons mentioned above, we are greatly indebted. In addition, our work was helped
incalculably by many local farmers and villagers in China and elsewhere. We cannot mention them
individually but we offer them all our sincere thanks. Without them, our work would not have
been successful.
