Comments On Specific Species

Fraxinus velutina. Modesto cultivar.

Salvia clevelandii. The first occurrence of this species was dead in 2003. The first live occurrence is also noted, but not numbered as a new species.

Rhus integrifolia. This may be a hybrid with sugar bush, Rhus ovata since the sepals are pink instead of green. We need to check for glands on the sepals.

Sambucus mexicana. These tree/bushes are very tall and very old. A few look to be mostly dead, but still have some live portions.

Salix laevigata. There is actually a small arroyo willow, Salix lasiolepis that occurs just before this species, but it is small and hidden within this tree. Since a large arroyo willow is immediately after this species, we have therefore chosen to not list this small one in the guide.
