Crocus sativus
"Crocus sativus" has a corm, which holds leaves, bracts, bracteole, and the flowering stalk. These are protected by the corm underground. "C. sativus" generally blooms with purple flowers in the autumn. The plant grows about 10 to 30 cm high. "C. sativus" is a triploid with 24 chromosomes, which means it has three times the haploid number of chromosomes. This makes the plant sterile due to its inability to pair chromosomes during meiosis.
