Pedicel florescence is only 3 mm long, fruit curved, long but not more than 6 mm; bracts membranous, about 5 mm long, inner 2 often close or connate; petals dark blue; inner surface 2 claws, nearly 1 cm long. Capsule oblong, 5-7 mm long, 2-loculed, 2-lobed, with 4 seeds. Seeds 2-3 mm long, brownish-yellow, flat at one end, flat in ventral surface, with irregular pits. The cryovial is made of medical polypropylene (PP) and is a disposable laboratory consumable specially used for storing biological samples. In the gaseous state of liquid nitrogen, it can withstand low temperature to
The sealing property finally ensures the safety of the samples in the tube. Caps come with a variety of embeddable color codes for easy identification.
