"The sterile florets of Phalaris are frequently mistaken for tufts of hair at the base of a solitary functional floret. Close examination will reveal that the hairs are actually growing from linear to narrowly lanceolate pieces of tissue. Developmental studies have shown that these structures are reduced lemmas".

Wildland weed widely planted for forage in California. Earliest Santa Cruz Mtns CCH2 specimens from 1950s. N.B. Out of focus field photos (like these) may not reliably separate plants from the genera Phleum and Alopecurus.

Small group of highly confusing oaks. Mature trees to 20 feet tall, but have ridiculously vicious leaf-spines on all the leaves. Characters seem to put them in the Intermediate Oaks, which, for the SC Mtns region, would make it canyon oak, Q. chrysolepis.

But the leaf-spines, which are far more needle-like than any we can find on Q. chrysolepis in the SC Mtns, in combo with the roundish, wavy leaves and warble-edged acorn cups suggest Q. palmeri. Even the branching pattern and bark seem similar to palmeri.

But the nearest occurrences of Q. palmeri are in the East Bay in Sunol. Nor are there any other known Q. chrysolepis on the preserve for a localized comparison.
