Carrot Family (Apiaceae)

Bowlesia Bowlesia incana M CP, Jep
Marsh Parsley Cyclospermum leptophyllum Probably a misidentification of Apiastrum angustifolium, which does occur at the BFS. RSA CP, Jep

Dogbane Family (Apocynaceae )

California Milkweed Asclepias californica Misidentification of A. eriocarpa. All Asclepias plants at the BFS key to A. eriocarpa. M CP, Jep
Narrow-leaf Milkweed Asclepias fascicularis May have occurred transiently by spread from the Rancho Santa Ana Botanic Garden, but does not persist at the BFS. EN CP, Jep

Sunflower Family (Asteraceae)

Western Ragweed Ambrosia psilostachya M CP, Jep
Emory Baccharis Baccharis salicina Formerly Baccharis emoryi. EN, M CP, Jep
Broom Baccharis Baccharis sarothroides This species does not occur in this region. Sundberg in The Jepson Manual states that Baccharis emoryi without stem leaves may key to B. sarathoides. R CP, Jep
Nevin’s Brickellbush Brickellia nevinii Possibly a misidentification of Brickellia californica. Would represent a range extension if present. M CP, Jep
Yellow Star-thistle Centaurea solstitialis Misidentification of Centaurea melitensis, the only Centaurea sp. confirmed at the BFS. SD CP, Jep
Flax-leaved Horseweed Erigeron bonariensis Originally reported as Conyza bonariensis. Assumed to be misidentification of Erigeron canadensis (now Erigeron canadensis). Both species may occur at the BFS, but only one species has been confirmed. EN CP, Jep

Q-Tips Micropus californicus? EN CP, Jep

Borage Family (Boraginaceae)

Mesa Fiddleneck Amsinckia spectabilis var. microcarpa Specimens originally deposited as A. spectabilis var. microcarpahave been determined to be A. intermedia. A. spectabilis var. microcarpa occurs in dune habitats of San Luis Obispo and Santa Barbara Counties, and the BFS is outside its range. RSA, JG CP, Jep
Yerba Santa Eriodictyon californicum The BFS is outside the range of Eriodictyon californicum. Only one species of Eriodictyon, E. trichocalyx, occurs at the BFS. R, RSA CP, Jep
Trask’s Yerba Santa Eriodictyon traskiae Specimen UCR108201, which is is actually E. trichocalyx, was originally listed in online as Eriodictyon traskiae because of a data entry mistake. The BFS would represent a range extension for this species. VS CP, Jep
Parry Phacelia Phacelia parryi May have been a misidentification of Phacelia minor. R CP, Jep

Mustard Family (Brassicaceae)

Radish Raphanus sativus Doubtful that this species occurs at the BFS. M CP, Jep

Cactus Family (Cactaceae)

Opuntia ‘occidentalis’ Uncertain what taxon was meant. The name Opuntia occidentalis, treated in The Jepson Manual as a named hybrid, O. X occidentalis, is regarded as the cross of O. littoralis X (O. engelmannii X O. phaecantha), which does not occur at the BFS. It has also been variously applied to O. littoralis, O. oricola, and even O. ficus-indica. O. oricola does not occur at the BFS, and O. littoralis and O. ficus-indica are listed under their correct names. M

Honeysuckle Family (Caprifoliaceae)

Honeysuckle Lonicera sp. Not confirmed. Doubtful that this species occurs at the BFS. R CP, Jep

Evening Primrose Family (Onagraceae)

Hill Sun Cup Tetrapteron graciliflorum Specimen RSA613089, originally deposited as Camissonia graciliflora, has been determined to be Camissoniopsis bistorta. The BFS would represent a range extension for Tetrapteron graciliflorum. RSA CP, Jep

Sticky Cinquefoil Drymocallis glandulosa Originally reported as Potentilla glandulosa. Probably a misidentification of Horkelia cuneata. M CP, Jep

Palm Family (Arecaceae)

California Fan Palm Washingtonia filifera As the palm on the south shore of the lake has grown, it’s become apparent that it’s W. robusta rather than W. filifera, i.e., “Mature trunk slender, ± brown, generally tapering from swollen base; leaf blade bright green, forming a compact crown” RSA764404, SD CP, Jep
Small-flowered Soap Plant Hooveria parviflora Originally reported as Chlorogalum parviflorum. The flowers of the soap plants at the BFS open in the evening. Flowers of Hooveria parviflorum open during the day. R CP, Jep

Sedge Family (Cyperaceae)

Common Spikerush Eleocharis macrostachya Voucher specimen was determined to be E. palustris, not E. macrostachya. VS CP, Jep
