Short-lobed Broom-rape [Orobanche parishii (Jeps.) Heckard ssp. brachyloba Heckard]
Listing CNPS List 1B R-E-D Code 2-2-2
State/Federal. Status -- /C1 OROBANCHACEAE May-Aug.
Global Rank G4?T2 State Rank S2.2
Distribution: San Diego County, San Luis Obispo County, San Nicolas Island, Santa Catalina Island, Santa Cruz Island, San Miguel Island, Santa Rosa Island; Baja California and Isla Guadalupe, Mexico
Habitat: Coastal Bluff Scrub and Coastal Dunes are the reported habitat for this species. On Point Loma the habitat (soils mapped as Terrace Escarpments) is a wind-swept, low-growing sage scrub with sandstone openings; at Torrey Pines this broomrape was reported at the edge of the pine canopy on a slope facing the ocean.
Known Sites: Three recent reports from San Diego County are along the Guy Fleming Trail at Torrey Pines Preserve (not noted at this locale during the following two years), on Point Loma Navy property near Fort Rosecrans (site inexplicably destroyed in 1988 for construction of a narrow repair road), and in a sandy bottom in Lux Canyon, Encinitas which has been brushed and is soon scheduled for development. Data Base reports are from San Miguel Island for the west side of Cuyler Harbor, at Harris Point Peninsula, 0.5 mile southeast of Adams Cove; from Santa Catalina Island from Ben Weston Beach; from San Nicolas Island 0.25 mile west of Elephant Seal Beach, northeast of Elephant Seal Beach, 0.25 mile northwest of San Nicholas Island, Dutch Harbor, 0.25 mile northeast of Daytona Beach, at the east end of the island 0.25 mile west of the lighthouse, on the road northwest of Jehemy Beach, just east of Dutch Harbor, south of Jackson Hill on a road near the beach, east of Sea Lion Beach on a road 0.25 mile inland, 0.25 mile inland from Elephant Seal Beach; from Santa Cruz Island between Black Point and Christi Ranch Beach, at the south end of Christi Ranch Beach; in San Luis Obispo County south of Oso Flaco Beach; and on the west end of Santa Rosa Island.
Collected in Baja California by Moran (SD 102353) at the head of a small arroyo, 2 km west of Cerro Solo at 31 10' North. The specimen is at the San Diego Natural History Museum.
Status: Short-lobed Broom-rape is close to extirpation in San Diego County. All populations should be fully protected with adequate buffers.
Baja Bur-comb [Pectocarya peninsularis I. M. Johnston]
Listing CNPS Unlisted R-E-D Code None
State/Federal. Status -- None BORAGINACEAE spring
Global Rank None State Rank None
Distribution: San Diego County; Baja California, Mexico
Habitat: Open, Sonoran Desert Scrub in sandy, silty, or gravelly soil is the reported habitat of this small annual.
Known Sites: U.S. reports of this species are from northwest of the Narrows and Borrego Valley.
The Baja Bur-comb is reported in Baja California from the Llano San Quintin south to the Desierto de Vizcaino.
Status: This species is superficially similar to several other bur-combs growing on the desert, and it may be more widely distributed than the few reports would indicate. Given the paucity of known U.S. sites, it is recommended that all U.S. populations should be protected.
