An automated data bank for Canadian grass genera has been established in Ottawa under the DELTA system, capable of generating detailed taxonomic descriptions and identification keys in English and French. The descriptive information available comprises 274 characters, mainly concerned with morphology, anatomy, physiology, and geographic distribution. The present capabilities of the system are described and illustrated by automatically typeset sample keys to the 109 genera known to occur in Canada (in English) and to the taxa of the Yukon (in English) and to those of Québec (in French); by automatically typeset sample descriptions of the genusFestucain computer-coded form (in English and in French); and by two microfiches carrying descriptions and keys for all the Canadian genera (in English and in French).
