Unconfirmed Plant Reports

The following plants have all been listed as occuring at the BFS, but we have been unable to confirm their presence. Some of the reported species appear to have been misidentified, and others may have represented transient populations that did not become established on the BFS.

If you can confirm that any of these species occur (or have occurred) at the BFS, please notify the webmaster.

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

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
Coastal Goldenbush, Menzie’s Goldenbush	Isocoma menziesii		R	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
Water Cress	Rorippa officinale	Originally reported as Rorippa nasturtium-aquaticum	R	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
Legume (Bean & Pea) Family (Fabaceae)

Beech Family (Fagaceae)
Maul Oak, Canyon Live Oak	Quercus chrysolepis		R	CP, Jep
Gooseberry or Currant Family (Grossulariaceae)
Bitter Gooseberry	Ribes amarum	Voucher specimen for this species was incorrectly labeled in database. It’s actually Ribes aureum var. aureum.	R	CP, Jep
Oakwoods Gooseberry	Ribes quercetorum		R	CP, Jep
Mint Family (Lamiaceae)
Wooly Bluecurls	Trichostema lanatum		M	CP, Jep
Miner’s Lettuce Family (Montiaceae)
Miner’s Lettuce	Claytonia perfoliata	Misidentification of Claytonia parvifolia.	SD	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
California Fuchsia	Epilobium canum ssp. canum		R, JG	CP, Jep
Mustard Evening-Primrose	Eulobus californicus		M	CP, Jep
Hooker’s Evening Primrose	Oenothera elata ssp. hirsutissima	May have appeared in the past as a waif.	R	CP, Jep

Denseflower Indian Paintbrush	Castilleja densiflora ssp. gracilis	May have appeared in the past as a waif.	M	CP, Jep
Paintbrush	Castilleja subinclusa ssp. subinclusa	May have appeared in the past as a waif.	M	CP, Jep

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

Bigbract Verbena	Verbena bracteata		M	CP, Jep
Grape Family (Vitaceae)
Desert Wild Grape	Vitis girdiana	Because the few Vitis plants on the BFS has not borne fruit, species identification is difficult. Plant may be V. californica, V. girdiana, or a hybrid.	EN, R, JG	CP, Jep
MONOCOTS
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
