DELTA sample data

M.J. Dallwitz and L. Watson

Implicit attributes

Unless indicated otherwise, the following attributes are implicit throughout the descriptions, except where the characters concerned are inapplicable.

Habit, vegetative morphology. Leaf blades not pseudopetiolate. Ligule present.

Inflorescence. Spikelet-bearing axes persistent. Spikelets not in distinct ‘long-and-short’ combinations.

Female-fertile spikelets, florets, fruit. Glumes present. Fruit smooth. Pericarp fused.

Photosynthetic pathway, leaf blade anatomy. Mesophyll without arm cells; without fusoids. Midrib without colourless tissue adaxially.

Special diagnostic feature. Fruiting inflorescence not as in maize.


We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
