The best year for four-nerve daisies

with 28 comments

The four-nerve daisy (Tetraneuris linearifolia and scaposa) is among the most common wildflowers in Austin, with a few occasionally blooming even in the winter. As with so many other wildflowers, they appear in their greatest numbers in the spring. That said, in the two decades I’ve been paying attention to nature in central Texas, I don’t recall seeing four-nerve daisy colonies as large and dense as some of the ones that have sprung up here this year.

I photographed the first and second groups on the east side of Yaupon Dr. on April 26th. The rocky ground is typical of my Great Hills neighborhood, thanks to the limestone substrate in the Edwards Plateau.

I’d come across the colony shown below on the west side of Spicewood Springs Rd. on April 20th. I think it’s the hugest I’ve ever seen.

UPDATE: In the previous post, the majority preferred the first photograph of Heller’s plantain.

More from nature on December 25, 2018

with 30 comments

Here are more things I encountered west of Morado Circle on the morning of December 25, 2018.
It’s not unusual to find a hole in the pad of a prickly pear cactus (Opuntia engelmannii).

Look at the complexity in the dense branches of a dead Ashe juniper tree (Juniperus ashei).
Some seed-capsule-bearing limbs of a Mexican buckeye tree (Ungnadia speciosa) reached in from behind.

Why this patch on the top surface of an otherwise dark rock was so light, I don’t know.

The bright fruits of a yaupon tree (Ilex vomitoria) in front of
an Ashe juniper may strike you as appropriate for the date.

And look at the wireweed that had sprouted in the power lines overhead.

Tip-top tuna

with 33 comments

As you probably already knew and recently heard here, compared to the northern United States, Texas is too far south and therefore too warm for a lot of grand fall color. Most of the relatively little we get leans more to yellow and brown than to red. That said, one saturated red we count on seeing as autumn advances each year is that of a ripe tuna. In this case it’s obviously not the word for a fish: Spanish uses tuna to designate the fruit of a prickly pear cactus (Opuntia spp.), and English has increasingly followed suit.

When I made up the post’s title I planned to include only the view from above, above.
Later, for people not familiar with this kind of fruit, I added a view from the side, below.

These pictures come from my neighborhood on November 2nd. The sheen is natural; I didn’t use flash.

Life and death in Saguaro National Park

with 14 comments

Behold a fishhook barrel cactus (Ferocactus wislizenii) in the eastern sector of Tucson’s Saguaro National Park as we saw it two years ago today:

Hardy as desert plants are, they all eventually meet their demise. Here’s what a barrel cactus look like then:

Oh, all right, it was Saguaro National Park, so I guess I’ll have to show you a saguaro cactus (Carnegiea gigantea). This one had two particularly enfolding “arms”:

And here are the stately remains of a saguaro with upraised “arms”:

How about this backlit cholla cactus in Tucson Mountain Park near sundown two years ago today?

A red theme

with 24 comments

Wanderers through countryside with lots of prickly pears (Opuntia engelmannii var. lindheimeri) know that the cactus often attracts certain bugs. This is one of those, Narnia femorata, on a tuna, or fruit of the prickly pear cactus, in the Zilker Nature Preserve seven years ago today. The bug is a nymph in one of its early instars, which are the developmental stages that the larva of an insect passes through. Click below if you’d like a closer look at the bug as it appeared in a different frame.

Although Texas in the summer of 2011 was suffering one of its worst droughts in decades, when I recently looked back at my archive for August 12th of that year I saw that I went photographing in four locations that day and ended up with hundreds of pictures, like this one along Scenic Drive of ripe snailseed fruit (Cocculus carolinus):

I also found from looking at my archive that I went out taking pictures on 19 of the 31 days in that torrid August of 2011. You could say that I lived up to the motto of the USPS (United States Photographic Service): “Neither heat nor drought nor sun nor sweat stays these intrepid image gatherers from the due documentation of their appointed rounds.”

Cactus wren nest in cholla cactus

with 8 comments

cactus-wren-nest-in-cholla-cactus-2471

On November 8th of 2016 in the eastern section of Tucson’s Saguaro National Park I saw what I take to be the nest of a cactus wren, Campylorhynchus brunneicapillus. The cactus is either a staghorn cholla, Cylindropuntia versicolor, or a buckhorn cholla, Cylindropuntia acanthocarpa.
