The word “star” is often used to describe a popular geometric shape that has symmetric radial points. These days, especially in the United States, we have decided that the usual number of rays for a “star” is five — perhaps because of the association with our flag, the “Stars and Stripes”. But the word can also be used for other variations, such as the “Star of David”, which has six points. Of course, a real star has a round shape, without any points. However, it is difficult to discern the precise shape of a star in the night sky with the naked eye — so it is easy to imagine a “star” shape.
We have applied the name of this shape to many living things, such as “starfish” (now often called “sea stars”) and “starfruit”. The word also appears in the names of flowers, such as “Star-of-Bethlehem” and “Yellow Stargrass”. However, the idea is often disguised, occurring in names that come from Latin or Greek roots. The genus Aster — derived from astér, another variation of the Greek word for star — is the name of a genus of daisy-like flowers. The Latin word for star is stella, and this word is even more common in the botanical names of flowers. For example, chickweeds belong to the genus Stellaria, named for the starry shape of the flowers. Another flower, called the Starry Campion, is Silene stellata — where “stellata” literally means “starry” or “star shaped”.
