New Zealand: Hooker’s mountain daisy

with 15 comments

At the Orokonui Ecosanctuary northeast of Dunedin on February 27th we saw some Hooker’s mountain daisies (Celmisia hookeri), a species classified as being at risk. Notice the white-margined leaves.

As with many other plants in the sunflower family, this one’s flower heads give way to puffball-type seed heads.

After the seeds fall away, the remains are rather sculptural:

Cowpen daisy

At Guadalupe River State Park on September 29th I found a cowpen daisy plant (Verbesina encelioides) that was flowering. Dig those dark shadows.

Only once before has Verbesina encelioides appeared in these pages. Does the genus name sound familiar? Perhaps it’s because frostweed is also in that genus.

As attractive as the flower heads of the cowpen daisy are, the plant has an unpleasant odor.

Stop and smell the nerve-ray

nerve-ray-flower-head-0013

On September 12 along a trail following the upper reaches of Bull Creek I found a few late-in-the-season flower heads of Tetragonotheca* texana, known as nerve-ray or square-bud daisy (did you notice the green square?). While most species of yellow daisies—and there’s a slew of them in central Texas—don’t have much of a scent, this one is fragrant, so I always make myself stop and smell the nerve-ray.

In the United States the aptly named T. texana grows only in Texas. Travis County, where Austin is, marks the northeastern corner of the species’ range. Lucky us.

* A tetragon is a four-angled figure: Greek tetra = 4 and gon = angle (and theca = a place to put something, a receptacle, a case). Notice that the more common Latin-derived word quadrilateral names the figure for its four sides rather than its four angles.
