Habitat  ?   Growing on the valley floor. There is grows with Lithocarpus densiflora var. echinoides and Torreya californica, and Arctostaphylos mariposa. 
Notes  ?   Conspicuous veins in bark. ″Dear Miss Eastwood: I am sending under separate cover some sprays of acrtostaphylos which I presume is A. mewuka but I am anxious for your opinion. It is growing on the Valley floor and just beyond the tunnel on the Wawona Rd. There it grows with Lithocarpus densiflora var. echinoides and Torreya californica, also Arctostaphylos mariposa. This plant community extends down the slope from the altitude of about 4,500. I have put in some branches of Lithocarpus so that you can note how conspicuious the veins are in the bark. Jepson in the Manual of Flowering Plants states that var. echinoides has inconspicuous veins so perhaps this shrub is not the var. echinoides. I hope that you and your sister are very well. I send love to you and send regards to Mr. Howell. Respectfully yours, Enid Michaels.″
