Mysteries Solved #3 - Mystery Bush

My 'Mystery Bush': Burroweed

I have almost identified everything that is a plant of any kind in my yard. I have some grasses to properly identify, and a few little bushes. Here's one of them.
EDIT: and I have identified this, now. Answer at the bottom.

This plant surrounding the cholla

Chia

Name - Chia (Salvia Columbariae), also known as golden chia

Chia flower

Kid Friendly? - Pretty little flowers and edible seeds
Garden friendly? - The flowers are pretty, small globes of flowers on long stem. The leaves have a nice minty smell when crushed. Not a showy flower, but very interesting looking. They can attract some of the smaller pollinators with their smaller blooms, although they will also self-pollinate. The flowers will be purple or white, although I've only seen purple in my area.
Look alike's? - There is more than one plant with the name 'chia.' The other chia is known as Salvia Hispanica. This has larger seeds and stems, although it, too, is edible. Commercially purchased chia, and those old 'chia pets,' are both Salvia Hispanica rather than Salvia Columbariae (interesting information on Salvia Hispanica).
Bloomed in: March 2013, with a late snow and early heat. By mid-April, I found some with a few blooms still on, but it looked like they were the last.

lyreleaf Jewelflower

Name - Lyreleaf Jewelflower (Streptanthus Carinatus)

Kid friendly? - According to wildflowers-and-weeds.com, all members of the brassicaceae family (which jewelflowers belong to) are edible, even if some don't taste very good. Other sources claim that only most of the brassicaceae family are edible. Jewelflowers are never listed as edible in any source I've found, so I wouldn't recommend tasting them. I have not found confirmation on whether jewelflowers are toxic, but based on their family and what information exists on members of that family, I would take this as a 'tentatively not poisonous' for right now.

Garden friendly? - This flower, as you might imagine from the name, is very pretty, very unique looking. I would definitely like it in my garden! Not sure about whether it discourages other plants, but it's worth looking at. Home to caterpillars.

Look alike's? - There are various Jewelflowers, but I could not find any other varieties listed in our desert.

Bloomed in: March 2013, with a late snow and early heat. Supposedly also blooms in late winter. Pods and seeds were formed on the stalk, with flowers already gone, by early April.

Esteve's Pincushion

Name - Esteve's Pincushion

Kid friendly? - unknown. 

Garden friendly? - quite a pretty little flower, no thorns, and seems to attract some kind of pollinators. No noticeable smell one way or the other. So, yeah, Garden friendly. The blooms last a little longer than some of the other wild flowers I've seen. 

Look alike's? - Pebble Pincushion, Bighead dusty maiden, pincushion flower. But they all look pretty, so honestly, not a big worry to misidentify this one, I wouldn't think.
Bloomed in: March 2013. Late snow and early heat both, this year.

The Firefly Forest Website

Even after only a few posts, I've already referenced a desert plants website more than once. I figured I'd better give it a post all to itself: fireflyforest.com
