To achieve a morphological and healthy characterization of fruits, seeds and seedlings of Chloroleucon tenuiflorum (Benth.) Barneby & J. W. Grimes, collected in northwestern Argentina, this work was performed. The mechanical scarification using sand paper and the immersion in sulfuric acid during different periods of time are the best to obtain higher levels of the % of accumulative germination. The IRP index reached 283% of increase after 48 hs; the correlation index length of fruit/ n˚ of seeds is optimum. The healthy seeds were the 84, 4%, while the unhealthy constituted the 15,15% ( aborted, destroyed, eaten or attacked ). The germinability allowed to confirm that the seeds are orthodox. Germination is epigeal, phanerocotyledonar, with photosynthesizing cotyledons, seedlings have two opposite protophylls and 1-2 alternate bipinnate eophylls. The lapse 24 - 48 hours after the moistening of pretreated seeds is optimum to obtain an effective % of germination
