The Chinese flora,with an estimated 30,000species,is of immense scientific and hortcultural importance.Noteworthy,too,is the traditional medicine of the country,which is based on the remarkable plant resources.Descriptions and identification keys for this diverse flora,until now unavilable in English,have been published over the past twelve years in the Flora of China,in conjunction with a separate illustrations series.Twenty-three of the total of 50 volumes have already been published,thanks to an unprecedented and long-standing collaboration between Western and Chinese scientists.

Volume 22 of the illustrations series is devoted to one plant family of enormous significance, namely , the grasses (Poaceae or Gramineae). The poaceae range from the bamboos within the tribe Bambuseae to the widelycultivated rice, wheat , barley, and maize or corn, as well as many grasses used for animal forage, all plants of unparalleled importance to human life. A large proportion of the species of grasses depicted here, including many woody bamboos, occur naturally only in China.
