Notes: Not clearly distinguishable from var. luteolum north of Tiburon. E. luteolum is similar to E. gracile to the south and E. vimineum to the northeast. Threatened by development, foot traffic, and non-native plants. See Flora Franciscana, pp. 150-151 (1891) by E. Greene for original description, and Phytologia 66(4):378-379 (1989) for alternative treatment which restricts var. caninum to ALA and MRN counties. |
