Poa compressa (Canada bluegrass) growing along the trails and roads in Story Mill Park, Bozeman, Gallatin County, Montana. Dense and almost pure stands of Canada bluegrass line the trails in certain parts of Story Mill Park. The distinctly banded nodes are often each associated with the point at which the leafy grass stem is bent. Note that all the leaf blades are born from the stem and not basally congested.

There is very little to distinguish this species from E. davidsonii, besides the tendency to show outward or lateral branches instead of straighter and more erect ones.

Not to mention E. davidsonii regularly forms dense populations, while cithariforme is more solitary and less common. Still, all variable points...

Tentatively. Massive split trunk. 7’ tall plant. No smaller plants in sight. Upper Santa Clara R. watershed (San Francisquito Cr.).

Keel somewhat swollen/convex with a short beak and long cilia. Strong grape scent. Clearly a shrub and likely very old.

The prostrate habit and relative broad ovate leaves are distinctive of this species and distinguish it from Amaranthus blitoides, which is another often prostrate amaranth in this area. Like Amaranthus blitoides, the flowers are congested into axillary clusters, but each bears 1-3 sepals and these are not obscured by the short subtending flower bracts. This site lies on a newly constructed area involving the Animal Bioscience Building on the Montana State University campus, Bozeman.

E. apiculatum is reliably found at this spot on the Cactus Spring Trail. On this trip, we found one very large plant surrounded by ten or so smaller plants.

The larger plant probably germinated from an earlier rain than the others, and then grew really large from the rain from the tropical storm remnants. This obs is for the big plant; the next obs is for one of the small plants:

Several of us tried to view the apiculate tip on the perianth lobes, but failed to see it in the field.

My pix show the main reason we missed it is that for these plants, the apiculate tip is actually like a very long awn, instead of a tooth!

I've circled the long awn on two perianth lobes in the first and third pix.
