Introduced Species

Proposed Species
http://www.edgehill.net/proposed.htm
Coastal Sagebrush Asteraceae
Artemisia californica
At least one surviving shrub found on the very upper slopes with Phacelia ramossisima
& Blue Dicks
Coyote Bush Asteraceae
Bacharis pilularis
Just a few plants remaining.
California Brome Poaceae
Bromus carinatus
Reported on site in May 1998 I found a couple clumps on Steve's Rocks May, 2000
amongst weedy Rye, Barley & Cheat Grass. Seeds collected August 2000.
Morning Glory Convolvulaceae
Calystegia purpurea
Many persisting on site especially above "The Wall" New seedlings are common.
Soap Plant Liliaceae
Chlorogalum pomeridianum
A few patches. Weed, protect, gather seed & replant a few bulbs.
Indian Lettuce Portulacaceae
Claytonia perfoliata
Occassional.
Blue Dicks Liliaceae
Dichelostemma capitatum
A couple of bulbs transplanted down on Paul's slope.
Coastal Wood Fern Pteridophyta (Division)
Dryopteris arguta
A couple of rhizomes transplanted to Paul's meadow. Do more divisions over time
when the existing clumps get young healthy shoots.
Liveforever Crassulaceae
Dudleya
Only the green leafed form remains but the green & siver forms occur side by side in
nearby open spaces. There are several abundant non-native succulents on Edgehill
Mountain that are somewhat similar.
California poppy Papaveraceae
Eschscholzia californica
Woodland Strawberry Rosaceae
Fragaria vesca
Occassional. Beneath the Elderberries we planted. Carefully weeding the ivies away
from them.
Bedstraw Rubiaceae
Galium aparine
Occassional. The coarse leaved type.
Toyon, Christmasberry Rosaceae
Heteromeles arbutifolia
A few plants remain. Laguna Honda nearby has Toyons that are so big that they look
like oak trees. Similar large specimens thrive on Yerba Buena Island.
Woodland Pea Fabaceae
Lathyrus vestitus
Common sprawling vine.
Creeping Wild Rye Poaceae
Leymus triticoides
Occasional from cracks in rocks & at the base of boulders.
European Rye (Weed) Poaceae
Lolium
Manroot, Wild Cucumber Cucurbitaceae
Marah fabaceus
Common.
Melic Grass Poaceae
Melica sp.
A single plant at the base of Paul's Slope
Sticky Monkey Flower Schrophulariaceae
Mimulus aurantiacus
Reported on site in May 1998, I have not seen any.
Purple Needle Grass Poaceae
Nassella pulchra
Reported on site in May 1998, I have not noticed any.
Branched Phacelia Hydrophyllaceae
Phacelia ramosissima
Seed spread 12-1999
An email to Joan Kingery:
"The Phacelia ramossisima seeds are sprouting! I gathered some seeds from up on
Spiers' land this summer & sprinkled them around Sunday after the planting. They are a
voracious weed that will grow like mad & be covered with white fiddle head flowers
that the bees will go crazy for. They bloom in spring & by late spring/early summer,
the leaves will dry up & look dead but don't worry next year there will be even more
because they are prolific seed makers. The seeds were collected from near one of the
geologic test pits where they dug up the ground revealing the old buried seed bank.
There was Brodaeia capitata, Blue Dicks growing there also. A FLORA OF SAN
FRANCISCO says P. ramossisima was found in the Presidio once but it was probably
a mistake. Scott Hoge at Rec & Park says he saw it over above Kensington. Phacelia
ramossisima ramossisima appeared on the list of species that he & Lisa put together
when they walked the site in '98. Regardless, it's happy there, will cover the ground
splendidly & will be the only verified population of the species in San Francisco
which should be interesting to the purists (myself included). It's also conceivable that
the seed fell off of the geologist's auger & it's a bastard plant. Or it could be a tiny
remnant population with a distinct genetic pattern to be named Phacelia ramossisima
edgehillensis (vastly idealistic scenario). The Jepson Manual of the Higher Plants of
California says "varieties are difficult and need study". I believe I saw the same stuff
on San Bruno Mountain Saturday also. Any ways, it was sprouting in the area that I
stabilized with rock "mulch" below your favorite fern patch & is getting a good head
start from the additional irrigation. (the Erharta grass is sprouting there too) I will
water again this weekend.
Abundant white fiddlehead flowers drive bees crazy. An important nectar source for
mission blue butterflies on Twin Peaks. When it dries up by early July it is real hard to
find. Prickly hairs can be a nuisance, some people are allergic. I’ve seen Phacelia
californica in many places but never seen ramosissima anywhere else.
California Polypody Pteridophyta (Division)
Polypodium californicum
Common. The polypody patches are the first place that people took a liking to & began
weeding & caring for the park.
Leather Fern Pteridophyta (Division)
Polypodium scouleri
Found on rocks & tree branches
Western Sword Fern Pteridophyta (Division)
Polystichum munitum
Occasional, surviving fine in the ivy.

Potentilla glandulosa
Occassional.
California Blackberry Rosaceae
Rubus ursinus
Common.

Sambucus
There are large colonies of Red Elderberry on the vacant lots of Edgehill Mountain
Pacific Snake Root Apiaceae
Sanicula crassicaulis
Common.
Bee Plant Schrophulariaceae
Scrophularia californica
Common in rocky places.
Stonecrop Crassulaceae
Sedum spathuifolium
Existing next door in a neighbor's yard (I can't find it now though).
Blue-eyed Grass Iridaceae

Existing on the median of Idora st. nearby, probably planted.
Wood Mint Lamiaceae
Stachys
Survives between ivy.
Snowberry Caprifoliaceae
