Unconfirmed Plant Reports – Revised 4 August 2014

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.

Common name Species name Notes Source* Photos &


Carrot Family (Apiaceae)

Bowlesia Bowlesia incana

M CP, Jep
Marsh Parsley Ciclospermum leptophyllum

Probably a misidentification of Apiastrum angustifolium, which does occur at the BFS.


Dogbane Family (Apocynaceae )

California Milkweed, Round-hooded 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
South American Conyza, Asthmaweed Conyza bonariensis

Assumed to be misidentification of Conyza 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
California Aster Lessingia filaginifolia var. bernardina and Lessingia filaginifolia var. peirsonii

These varieties are no longer recognized. The Jepson Manual includes vars. bernadina and peirsonii in Lessingia filaginifolia var. filaginifolia.

Slender Cottonweed Micropus californicus?

EN CP, Jep

Borage Family (Boraginaceae)

Fiddleneck Amsinckia spectabilis var. microcarpa

Specimens POM612662 and UCR108167 were originally deposited as A. spectabilis. POM612662 has been determined to be A. intermedia, and we suspect UCR108167 is also. A spectabilis var. microcarpa occurs in dune habitats of San Luis Obispo and Santa Barbara Counties, and the BFS is outside its range.

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 described in online data 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 nasturtium-aquaticum

R CP, Jep
Hedge Mustard Sisymbrium officinale

Specimen RSA748150, originally deposited as S. officinale, has been determined to be S. orientale.

JW 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.


Honeysuckle Family (Caprifoliaceae)

Honeysuckle Lonicera sp.

Not confirmed. Doubtful that this species occurs at the BFS.

R CP, Jep

Legume (Bean & Pea) Family (Fabaceae)

Silver Bush Lupine Lupinus albifrons var. albifrons

Doubtful that this species occurs at the BFS.

M CP, Jep

Beech Family (Fagaceae)

Maul Oak, Canyon Live Oak Quercus chrysolepis

R CP, Jep

Gooseberry or Currant Family (Grossulariaceae)

Oak 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 Camissonia graciliflora

Specimen RSA613089, originally deposited as C. graciliflora, has been determined to be C. bistorta. The BFS would represent a range extension for C. graciliflora.

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.

Broom-rape Family (Orobanchaceae)

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.

Lopseed Family (Phrymaceae)

Common Monkeyflower Mimulus guttatus R CP, Jep

Plantain Family (Plantaginaceae)

Dot-Seed Plantain, Foothill Plantain Plantago erecta R CP, Jep
Water Speedwell Veronica anagallis-aquatica R CP, Jep

Phlox Family (Polemoniaceae)

Giant Woolstar, Blue Mantle Eriastrum densifolium ssp. austromonatanum

Does not occur at the BFS.

R CP, Jep
Turkish Rugging Chorizanthe staticoides

Possibly a misidentification of Lastarriaea coriacea.

R CP, Jep
Hooked Navarretia Navarretia hamata

Apparent misidentification of Navarretia atractyloides

EN, JG CP, Jep

Buckwheat Family (Polygonaceae)

California Buckwheat Eriogonum fasciculatum var. polifolium

Have not been able to confirm any Eriogonum fasciculatum with leaves tomentose above, and the BFS is outside the reported range of this variety.

EN, R, JG, M CP, Jep
Curly Dock Rumex crispus

Misidentification of Rumex hymenosepalus.

R CP, Jep

Buttercup Family (Ranunculaceae)

Southern California Clematis, Few-flowered Clematis Clematis pauciflora

Assumed to be a misidentification of Clematis lasiantha, the only Clematis speceis confirmed at the BFS.

S BFS, CP, Jep

Coffeeberry Family (Rhamnaceae)

Holly-leaf Redberry Rhamnus ilicifolia R CP, Jep
Sticky Cinquefoil Potentilla glandulosa

Probably a misidentification of Horkelia cuneata.

M CP, Jep
Firethorn Pyracantha sp.

Originally reported as one individual in the streambed near the road crossing, these plants, which superficially resemble Pyracantha, have black, not red, berries. They remain unidentified.

EN CP, Jep

Willow Family (Salicaceae)

Narrow-leaved Willow Salix exigua R CP, Jep

Figwort Family (Scrophulariaceae)

California Figwort Scrophularia californica

Misidentification of S. peregrina, which is the only Scrophularia species at the BFS.

R, M CP, Jep

Nightshade Family (Solanaceae)

Nodding Nightshade Solanum americanum

Possible misidentification of S. douglasii. (Originally reported as S. nodiflorum, a name that is no longer valid; it is considered a synonym for S. americanum. [Jep])

M CP, Jep

Elm Family (Ulmaceae)

Elm Ulmus sp. EN CP, Jep

Vervain Family (Verbenaceae)

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


Rush Family (Juncaceae)

Common Rush Juncus effusus var. brunneus

Originally reported under this name in 1997. Reclassified as Juncus effusus ssp. austrocalifornicus, a name that wasn’t accepted until 2004.

Lily Family (Liliaceae)

Small-flowered Soap Plant Chlorogalum parviflorum

The flowers of the soap plants at the BFS open in the evening. Flowers of Chlorogalum parviflorum open during the day.
