Observable characteristics. Use only the observable features of the organisms.

Major characteristics comes first, always start with the chief characteristics, placing organisms into two groups at each stage.

Use of single characteristics at a time
use contrasting characteristics at each stage like 1(a) short, 1(b) tall

Avoid repetition. Avoid repeating the same characteristics.
