The natural resources of the Nipomo Dunes and Wetlands, California Department of Fish and Game, 1976

I stumbled on this. A good report with lists and maps in appendices. Please read if you are interested in the conservation of the Coastal Dunes and Wetlands or just interested.

I will try to add species mentioned in the report below, although there are many.

An interesting patch of Lupinus bicolor.

The other day I was driving around and I thought I saw white Lupine. Upon closer inspection, it turned out to be a very large form of Lupinus bicolor. The so called miniature Lupine can be not very miniature at all!

Most of these were not white as I had thought, but very pale blue, instead of the usual darker blue. A small few were the usual darker blue, as you can see below.

I checked the plant against the key to be sure. The banner is tapered and is longer than wide. The keel is ciliate from middle to tip. The flowers are whorled, of course. This one is fruiting, some quite large.

The plants grow up to 30 cm. The pedicel is quite long for L. bicolor at 3.5 mm or so.

The misidentification of Lupinus nanus or Lupinus bicolor

Are you good with Lupine sp. ?

Last year, and this year I practiced using the Jepson eFlora key to Lupinus. I identified several annuals and learned the main difference to confirm between L. nanus, and L. bicolor is the proportion of the banner petal. There are others on the key with a similar banner to L. bicolor, but I didn't expect to see them in the area I was looking, so I could safely ignore those.

Between L. nanus and L. bicolor the keel margin cilia are about the same. In L. nanus the banner is about as wide as long, or slightly wider than long. In L. bicolor the banner is longer than wide. Sometimes it is obvious. Once you get to know the local population, it is clear, as well.

L. nanus are generally larger, more densely packed whorls, and very fragrant in my experience. They also form large groups of plants. L. bicolor is usually smaller, and less dense. There are some other annuals in the branch of the key that L. bicolor is in, so you also check for a tooth on the keel. But I think the species in that group are not around San Luis Obispo County, if I recall correctly.

All this to say, if I look through all the observations of L. bicolor, I easily find many I'm sure are L. nanus to my eyes. People confirm their ID, and others jump on, but then they can't always explain why they made the choice. I think they're just looking at photos.

Then, north of here (San Mateo County, and north), apparently the banner on L. bicolor can look less narrow than smaller ones I've seen further south. At least from what I see people posting, and they assure me it is L. bicolor, but I can't tell by their photo.

Let's all please be more careful with these because they look so similar.

Amblyopappus pusillus, please look for this plant.

I'm reading Shore Wildflowers of California, Oregon, and Washington, by Philip A. Munz, and he mentioned some species I would like to find. If anyone out there sees them, let me know. I suppose I could create a project for it, but we will see.

Family Asteraceae;

Amblyopappus pusillus
Very small heads, no ray flowers, only minute , tubular disk flowers. Entire or somewhat divided leaves. On beaches, old dunes, and bluffs coastal SLO County to Baja. Flowering March - June. (Rephrased from Munz).

Recommended books to identify plants in the San Luis Obispo County area.

A beautiful introduction to the area is Wildflowers of San Luis Obispo, California, Edited by David J. Keil, PH.D. which is an excellent modern book with great color photos, and was "a cooperative project of the City of San Luis Obispo and the San Luis Obispo Chapter of the California Native Plant Society." (page 5) Any book by the CNPS is very good, by the way. They are a good organization, with a respected history, and dedicated to preserving and cataloging California natives, and watching invasives.

Central Coast Wildflowers, Monterey, San Luis Obispo, and Santa Barbara Counties of California by Mary Coffeen is also very good, with nice descriptions, and color plates. A little older, so check for scientific name updates online, perhaps by searching Calflora, but also the Jepson online should have a history of changes.

For the dunes, try Dune Mother's Wildflower Guide, Dunes of Coastal San Luis Obispo & Santa Barbara Counties, California, by Malcolm McLeod, California Native Plant Society. Excellent.

For the keys, use the Jepson online.
