Amphiachyris dracunculoides

Impatient pics on a windy, cloudy day. Plants scattered sporadically from here to at least the low water crossing on river terrace occasionally flooded when Lake Georgetown backs up in some years. Don't think I have seen these in this area before, so perhaps washed in from upstream fields. Just for fun some Gutierrezia texana occur in the same area.

National Butterfly Center

This is the actual native Passiflora foetida, not to be confused with the introduced P. lanuginosa that the vast majority of people of Texas are more familiar with and usually is mistakenly called P. foetida. You can use the distinctions listed below to tell the two species apart.

In our area:

P. lanuginosa:
Usually larger darker leaves with the lobes usually being larger, more angular, and coming to a point
Stems and leaves can be anywhere between hairless to densely hairy
Leaves have little to no smell when lightly rubbed
Pink/white/pink coronal filaments with pinkish petals/sepals (occasionally white)
Hairless fruit that turns red at full maturity
An introduced species, usually found on disturbed sites / around human habitation
Aggressive growth habit; spreading

P. foetida:
Usually smaller lighter green leaves with the same basic shape as the leaves of P. lanuginosa, although with smaller more rounded lobes, usually not coming to a defined point
Leaves densely hairy; truly velvet-like in texture
Leaves give off a strong funky smell when lightly rubbed (to me it smells like cheese)
Bluish-purple coronal filaments with white petals/sepals
Hairy fruit that stays green at full maturity
Native species usually found on less disturbed sites; in Texas limited to south Texas
Smaller, less vigorous species than P. ciliata; not spreading
Reaches the northern limit of its range in Texas around the northside of San Antonio

Here is a good example of actual P. foetida:

Aphanostephus skirrhobasis

Large patch of plants. Annuals. Under magnification (40x), at least some achene hairs appear coiled apically, indicating A. skirrhobasis over A. ramosissimus. It is unclear if all achene hairs are coiled this way as even at 40x, it is not always easy to see. In the field, with a 30x pocket scope, I could only tell that some hairs might be apically thickened or possibly hooked and I was unable to capture any of these hairs well via macro lens in the field. Turner's work on Aphanostephus (Taxonomy of the Genus Aphanostephus (Asteraceae-Astereae) - 1984) makes it sound as if this morphology should be clear at 30x magnification, but that was not my experience (though I don't have the best scope). He apparently originally discovered the difference in hair morphology when examining chromosome numbers via meiotic squashes, so it is possible that he was used to seeing them under higher magnification. There is a line drawing in his work which shows the difference in hair morphology, and it shows some differences which I think would only be visible under higher magnification. On the specimens I examined, the achene hairs were on the order of .1mm long.

Turner also mentioned sometimes finding up to three Aphanostephus species "cohabitating" or even "intermixing" in the case of A. skirrohobasis and A. ramosissimus, so while this observation indicates the presence A. skirrhobasis at this particular spot at Timberlake, it does not rule out the possibility of A. ramosissimus elsewhere. It does cast doubt on observations that have been identified to species where the achene hairs have not been examined, which is probably all of them.

I find it curious that the Flora of North Central Texas, which cites Turner's work, does not reference the difference in achene hair morphology, instead using other features which seem difficult to use. The pappus however did seem scaly rather than hairy, though the scales seemed numerous rather than limited to 5 as suggested for A. skirrhobasis.

Lindernia sp.

Common around this particular seasonal pond.

While I suspect that this might in some way qualify as L. anagallidea, I did not take a close look at all the features, particularly the lower leaves. There has apparently been some disagreement on how to treat forms fitting L. anagallidea. The Flora of North Central Texas treats it as L. dubia var. anagallidea, while noting that some authors recommend lumping it with L. dubia var. dubia. Weakley (2023) lists it as a species, but notes under L. dubia var. dubia that some authors apparently treat them as forms of the same species.

Zeltnera calycosa

Nice sized patch on north side of road across from one of the informational kiosks. One of a multitude of Z. calycosa specimens I observed throughout the day. This specimen was single stemmed with corolla lobes about 7.5x3.5mm, the tube about 12 mm, and calyx about 10.5mm. The largest leaf, towards the base, was about 15x4.5mm. This specimen was one of the most robust at this spot. Most at this spot were single stemmed from what I could tell, but I definitely saw other spots where the specimens appeared multi-stemmed and some spots where single stemmed plants were growing so close together as to appear to be multi-stemmed.

描述

This is Lantana camara. Lantana camara was introduced over a century ago on this island and is a self-sustained introduced population. The plant has not proven to be particularly invasive here, the climate is perhaps too wet for Lantana camara to outcompete the many other invasives on the island. Note that the computer vision top choice was Lantana horrida, and Lantana × urticoides was a third option. This, for me, explains the frequent misidentification of Lantana camara as Lantana horrida or Lantana × urticoides.

Note too how the colors shift: the seventh image suggests that some florets were yellow, but to the naked eye they were clearly orange. Exposure choices made by my Motorola Moto G6 altered the colors from what is seen in person.

As for the ID, note the finely toothed margins, the reduced floral bractlets, the flat blade. This observation is a good example of a lantana that does not have the lavender/fuchsia/pink florets but rather has the floret color spectrum of Lantana × urticoides and yet is fully Lantana camara.

Linum imbricatum

Patch of plants in light colored sandy soil which seems to have accumulated on a flat part of the mostly downhill Bluff Trail Loop. Distinguished from L. hudsonioides (which occurs in the nearby uplands of the park) by the ciliate margins found on some upper leaves. It was quite difficult to see the ciliate margins. With a 10x loop I could only see what might have been ciliate margins, but also could have been hairs on the adjacent stem. With a 30x pocket microscope, I could see that there were ciliate margins on at least some of the upper leaves (midstem and upwards), but it did not appear that all the margins were ciliate. Photography of these minute cilia was also difficult since I could never tell if they were in focus and they did not respond well to the direct light of the onboard flash.

I arrived at these plants early in the afternoon and within about 45 minutes almost all of the petals had fallen (or popped off in a ring), as they tend to do in these species.

Plants were up to about 11cm. Petal lobes (measured from top center in flower) were about 8mm.

Found this patch based on this recent observation:
https://www.inaturalist.org/observations/155017445

A last note. Although all the plants within about a 5 meter radius appeared to be L. imbricatum, there was an isolated individual in the taller vegetation about 20-30m away which appeared to be L. hudsonioides.

Linum hudsonioides

Probably Linum hudsonioides. Small patch in flower along Ridge trail in sparsely gravelly compacted sandy soil. For the most part, the leaves appeared entire, not ciliate margined as in L. imbricatum. However, it does appear that this population had some occasional really minute cilia at the base of some leaves. I don't know if that occurs in other populations or maybe because there be some slight intermediacy in this area due to the proximity of L. imbricatum (maybe just a few hundred meters away on the Bluff Trail).

Plants were to about 15cm tall, with petals approximately 8-9mm.

After seeing sporadic occurrences of Geranium carolinianum on the lowland trails thoughout the day, I finally find a couple of specimens of G. texanum at the end of the loop only a few meters from where I started the hike, in the heavily mowed margin of the trail near the gate in a sea of Medicago minima. By this late in the day the petals on the one bloom I found were already falling off, and some had done so by the time I finished handling the plant to take photos.
