Milla biflora Cav, is one of six species of this genus reported to be present in Mexico. To determine the present and potential seed production of this plant, the following characteristics were studied: the number of flowers per scape, the frequencies of scape with defined number of flower per scape, the conversion of flowers into capsules, the capsule size, seed numbers, average seed size per capsule. Samplings were taken from the natural stands and evaluation of the respective attributes was done in plants growing in germplasm collection belonging to the University UPAEP. The number of flowers ranged from 1 to 10 per scape, with 90.6% of scapes giving from 1 to 6 flowers. The capsules were formed from flowers in the following proportions: in scapes with one flower - 13.64%, in scapes with 3 flowers - 48.21%, in scapes with four or more flowers - 60%; 67.80 of capsules gave from 60 to 140 seeds; 45% of seeds had the average size from 1.81 to 2.20 mg. The mean weight of 1000 seeds was 1937.2 mg. The seeds germinated during 7 days in water, in 88 to 100%. The plant emergence from soil sown seeds ranged from 41.4 to 1OO %. The seeds have not lost the germination ability after 2 years of storage at room conditions.Milla biflora Cav, is one of six species of this genus reported to be present in Mexico.
