Differences between blue flax and sesame flowers

1. Leaf Difference

The leaves of blue flax are thin and numerous, arranged in a linear spiral. The leaves are alternate, narrow or linear-lanceolate, about 8 to 25 mm long and 3 to 8 mm wide. The leaves have an entire margin that is rolled inward, with a sharp tip and a gradually narrow base.

The leaves of sesame flowers are oblanceolate, 1.5 to 11 cm long including the stalk, and 6 to 13 mm wide.

2. Flower Differences

There are many blue flax flowers, forming a cyme. The flowers are blue, blue-purple, and light blue. The flower diameter is about 2 cm. The pedicels are slender, about 1 to 2.5 cm long, upright or curved to one side. There are usually 5 petals, which are obovate, 1 to 1.8 cm long, rounded at the top and wedge-shaped at the base.

Sesame flowers are in umbels with 3 to 10 flowers. The pedicels are 2 to 11 mm long. The petals are strip-shaped and oblanceolate, about 6 to 13 mm long and 2 to 3 mm wide.
