Description

Here are some of my original photos of the Travis County Trillium plant. I first discovered the plant on March 22, 1984 (first two images). I came back to measure the plant on March 24 (3rd - 5th images), and over the next few days invited several botanists and friends to view and photograph the plant. The 6th image (3/25/84) shows Dr. Marshall Johnston documenting the plant. The 7th image shows a young and curious Greg Lasley wondering what all the fuss is about.

Brushy Creek/Champion Park
4/21/2017
Geranium sp.

I saw a number of these Geraniums around Williamson county in 2017 and unknowingly took shots of them in previous years as well. At first glance they look like G. carolinianum. However, they have 5 purple anthers instead of the 10 yellow anthers of G. carolinianum.

The only Geranium I have found in the literature which has only 5 anthers is G. pusillum. However, other characteristics of this plant, such as the pubescense on the sepals and pedicels and also the petal shape is different from what is described for G. pusillum. In fact the pubescence on these plants is a much better match for G. texanum (minute appressed hairs abaxially on the sepal veins mostly with retrorse appressed hairs on the pedicels), which is what I thought these plants were until I noticed the 5 purple anthers.

As mentioned, I have seen them in various places around Williamson county from out near Camp Tejas in the western part to Brushy Creek and Berry Springs more centrally and also Granger Lake in the east. However, though they appear to be somewhat common in Wilco, I have not been able to find any other Geranium observations in Texas on iNat that seem to match these (though only a small percentage of observations have photos good enough to use). Anyway, I thought I'd tag some of the frequent observers of Wilco plants and the surrounding areas to keep their eye out for this one. If anyone happens to have any other clues what it might be, that would be great, but I'd also like to see if the range is any greater than what I have seen.

Common in some of the shorter grassy areas. This specimen was one of the taller ones I saw on the day, actually exhibiting a fair amount of unbranched stem basally, unlike many specimens of this species.

The technical way of differentiating Zeltneras from Centauriums is by the shape and amount of separation of the stigma lobes. These details are unfortunately difficult to photograph, especially on Zeltneras where they are typically smaller. These were taken with a 100mm macro at 1:1 and cropped 50%. I actually couldn't tell if they were in focus when taking the photographs. Many were not.

I would love help in IDing this red sage, which looks similar to cedar sage, but the leaves have a more papery texture, the plant grows 3-4 feet in height, and is a prolific bloomer and spreader. Its defining characteristic is that while gorgeous to look at, it smells like herbaceous cat urine when crushed, pulled, or cut. The smell is powerful, lingering on hands or clothes until they are washed. It is one of the first sages to emerge after the winter, and one of the last to die back as freezes set in. Once it comes up, it is constantly setting forth vivid red spikes of trumpet-shaped flowers.

Following the branches to their joints, the trunk of the hackberry stuck out in a crevice where the oak split its trunk, and the rest of it was embedded deep into the heart of the oak. Who knows how long it took for that oak to grow that far around it? How did the hackberry even survive?

How is it possible that I've never seen this until now? Based on the size it appears to have been here for quite a while. Where did it even come from? I don't even think there are any other observations of this species here...

First all those rainlilies, now this. The rain last weekend has really worked miracles.
I'm going to check some of the other swampy areas to see if there could be more...

This is really what I love about plants though. Even when you think you've seen everything somewhere, something new and spectacular will pop up!

Edit: I was wrong. RIP. Unfortunately it turned out to be nonnative Tropical Milkweed rather than the uncommon Butterfly Weed. But then again, another thing I love about plants: there's always plenty of room to learn!

I was watching this butterfly for a while. It was flying around, quite jittery of outside movement, when it suddenly stopped, fluttered in circles around a nearby oak (I believe a planted Quercus sinuata) before landing on the truck. I decided to try and get a few photos of it before it would inevitably noticed my presence and scatter off again. but surprisingly, it did not seem bothered by my presence as I moved closer to try and get better shots.

It was around this time I noticed its proboscis sticking out from the camera screen. Perplexed at what it was tasting, I peered around my phone to see, and noticed the sap oozing out of the broken twig it was resting on. The butterfly was feeding on the sap, probing its proboscis between the torn fibers and thoroughly enjoying itself.

In fact, there must have been something in the sap, either a lot of sugar, or maybe some fermentation, because it started to unstably totter around a bit. Almost like it was high on the sugar or something similar! Likely the reason it didn't notice or react to my presence was due to its thorough enjoyment of its lucky find. So engrossed was it in its behavior that a lucky bird could've easily snatched it up! Though it does look like it may have already had some past experiences with birds.
