Summary The use of the computer to map and/or plot systematic data is examined in the areas of automatic plotting of taxa's distributions and computer graphic analysis of geographic variation and population differentiation. Automatic plotting of distributional data is discussed in reference to earlier work and present applications in conjunction with the development of the Rapid Access Plant Information Center (RAPIC) of Colorado, (USA). In the area of computer graphic analysis of geographic variation, the following techniques are discussed: contour mapping (2 and 3 dimensional); shading by overprinting; contoured factor analysis; and contoured surface trend analysis. A technique of composite overlay mapping is introduced to systematics and several applications are discussed.
