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.

A Solo Trio

A developing flower of Xyris ambigua

 

Having shown more abstract images of a yellow-eyed grass (Xyris ambigua), it seemed only right to offer a more detailed look at this lovely plant.

Yellow-eyed-grasses not only belong in their own genus — Xyris  — they also belong in their own family: the Xyridaceae. More closely aligned with grasses than with other flowering plants, they thrive in wet places, specializing in acid or sandy soils, moist pine or oak savannas, pine flatwoods, pond shores, ditches, and bogs. These photos, taken in the wetland pine savannah of the Big Thicket Solo Tract, might just as easily have come from surrounding bogs.

A relatively tall plant that often grows to a height of three feet, its conspicuous cone-like inflorescence can be more than an inch long; tightly wound green and brown bracts subtend the pretty yellow flower.

Double or even triple flowers occasionally appear simultaneously
From bud to flower to seed

I especially enjoy the opportunity to see various stages of plant life on a single day. The experience brings to mind this passage from Ralph Waldo Emerson’s essay on self-reliance:

These roses under my window make no reference to former roses or to better ones… There is simply the rose; it is perfect in every moment of its existence. Before a leaf-bud has burst, its whole life acts; in the full-blown flower there is no more; in the leafless root there is no less. Its nature is satisfied, and it satisfies nature, in all moments alike. But man postpones or remembers; he does not live in the present, but with reverted eye laments the past, or, heedless of the riches that surround him, stands on tiptoe to foresee the future. He cannot be happy and strong until he too lives with nature in the present, above time.

Tête-à-Tête

Two Gray Hairstreaks sipping nectar from antelope horn milkweed (Asclepias asperula)
(click image for greater clarity and detail)

 

One of the most common butterflies on the North American continent, the Gray Hairstreak (Strymon melinus) also ranges into Central and northern South America.

In their book Butterflies of Houston and Southeast Texas, John and Gloria Tveten describe hairstreaks as “fast-flying butterflies that dart about so quickly and erratically that they are extremely difficult to follow.”  I’ve certainly been frustrated by that behavior, but this pair, intent on sips of nectar, were more than willing to tolerate my presence.

Found on a milkweed-covered  hillside along the west prong of the Medina River, very near The Nature Conservancy’s Love Creek Preserve, these hairstreaks were accompanied by Buckeye, Sulphur, and American Painted Lady butterflies: all enjoying the abundance of late spring flowers, and perfect flying conditions.
