Barbara, Unbuttoned

A blooming Button in the Big Thicket’s Solo Tract

The pretty flower known as Grassleaf Barbara’s Buttons (Marshallia graminifolia) occurs naturally in flatwoods, bogs, seepage slopes, wet prairies, and savannas; it’s quite common in east Texas’s Big Thicket.

All species in the genus commonly are known as Barbara’s buttons, although the identity of ‘Barbara’ is unknown. The common name first appeared in John Kunkel Small’s Flora of the Southeastern United States; published in 1933. The genus name, Marshallia, honors American botanists Humphry Marshall (1722-1801) and his nephew Moses Marshall (1758-1813), while the species epithet refers to the plant’s grasslike leaves.

Although a member of the sunflower family, the flower heads are composed only of disc florets; ray florets, often sometimes called ‘petals,’ are absent. In bloom, the flower’s compact form makes a comparison with buttons understandable; as buds, they seem even more button-like.

An interesting aspect of the flower is the way it sometimes comes into bloom: asymmetrically, if not erratically. I’m often amused by the forms it takes. Here, Barbara looks less like a button and more like a pig-tailed bud that’s cute as a button.

I caught this flower presenting a tentative wave to the world. Perhaps it felt a bit buttoned-up, and sent one of its florets to determine if it was safe to bloom.
