Through image analysis technique, germination stages of Chloraea crispa Lindl. were evaluated. The four germination steps proposed by Mitchell could be observed. Zero step corresponding to ungerminated seeds, there are lengthened, curved in one point, and 0.5 mm in mean. In step one just width increase due to embryo growth was observed. In step two there was changing in form and initial diameter was ten times higher. In step three the only marked eye visible, the physiological germination initiates. Germination percentage determined by this technique varied between 33 and 40 %.
