Cressa truxillensis | |
Cressa truxillensis is a species of flowering plant in the morning glory family known by the common name spreading alkaliweed. It is native to the western United States and Mexico, where it grows in habitat with saline or alkaline soils, such as beaches, desert flats, and playas.
This is a perennial herb producing an erect stem with many branches up to about 25 cm (10 in) tall. The clump of stems is densely lined with silky hairs and studded with many small hairy oval leaves, each under a centimeter long. Flowers appear in the axils of the uppermost leaves. Each has a white corolla with five pointed lobes surrounded by hairy green sepals. There are five protruding stamens and two styles.
In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately. Buds may be specialized to develop flowers or short shoots, or may have the potential for general shoot development. The term bud is also used in zoology, where it refers to an outgrowth from the body which can develop into a new individual.
