This flower looks just like one of those in the clusters I'm familiar with in Brodiaeas. I have never seen a single blossom like this so close to the ground.
I'm not sure what species this one is.
I can report that here are at least three species of Hordeums growing in Moore Creek Preserve thanks to Steve Gerow's assistance. Two are introduced species, and one a native. They are, from top to bottom: H. murinum, H. marinum and Hordeum brachyantherum.
Smaller than the similar Farmer's Barley, Hordeum murinum. In my older books Mediterranean Barley, H. marinum seems to have been H. hystrix.
Growing in footpath. Formerly called Orthocarpus pusillus.
A large gall on stem of Quercus agrifolia. It felt hollow.
I found these beetle larvae on Rumex leaves. I saw adult Green Dock Beetles and eggs today in the same area, so I am guessing these are Green Dock Beetle larvae, Gastroidea cyanea. If not it likely some other Chrysomelidae larvae.
I'm pretty sure these are eggs of a Green Dock Beetle, Gastroidea cyanea.
This one had a dark green metallic sheen.
Convinced it is a Heterosilpha, but can't distinguish whether it is H. ramosa or H. aenescens with just this photo as a record.
Heard many in wooded ravines with Coast Live Oak.
A smaller, daintier Equisetum than I usually encounter.
It was good to see a fair amount of this grass in Moore Creek Preserve. Looking at patches of it from a distance, the purple really stood out from the surrounding green.
