What are the characteristics of blue grass?

Orchids are perennial herbs and monocots. Roots are long and tubular. Leaves clustered from stems, linear-lanceolate, slightly leathery, 2-3 in bundles. Orchid is a famous traditional flower in China, which is famous for its fragrance. Orchids are characterized by their unique leaves, flowers and fragrance, which have four characteristics (clear air, clear color, clear air and clear rhyme), noble and elegant.

Roots are fleshy, hairless, and can fully grow. Pseudobulb, commonly known as Reuters, is covered with leaf sheaths. Many pseudobulb are often connected and exist in rows at the same time. Leaves are linear or sword-shaped, leathery, erect or drooping, flowers are solitary or in racemes, and many bracts are attached to pedicels. Flowers are bisexual and fragrant. Corolla consists of 3 sepals, 3 petals and pistil. 1 The middle sepal is called the main petal. The next two pieces are attached valves, and the extension of the attached valves is called home. The upper two petals are upright, fleshy and curled inward at the top, commonly known as hugs. The lower part 1 is a big lip, commonly known as Sun Lan. When mature, it is brown, and the seeds are small and powdery. Symmetry, lip, pollen block and pistil column are the basic characteristics of orchids: for example, Phalaenopsis can clearly see symmetry; Careful observation can clearly see the special lips; Pistil column is easy to understand, which is a unique feature of Orchidaceae plants formed by the combination of pistil and pistil; There are some exceptions to the characteristics of pollen clumping. Except PseudoOrchidaceae and Cyperaceae, most other Orchidaceae plants have pollen stalks. The ancients regarded "one flower and one stem as orchid", and one flower and many stems were beneficial.
