Provisional Plant Checklist tabulation for McGee Peak, Shasta County.

Magee Peak, Shasta County is a subalpine summit situated about 20 miles northward from Mt. Lassen. MaGee Volcano exploded with a caldera eruption about 220kA ago. The peak has an extensive cirque on the north facing caldera wall and floor, and a blast zone to the north containing about 70 lakes of various sizes. McGee Peak (8549 ft) and Crater Peak (8683 ft) are the highest summits on the rim of the caldera. The region is designated as the Thousand Lakes wilderness, although about 930 lakes shy of that number.

This checklist is based on CCH specimen records and on my 1974-1975 collections: Frank W. Peirson collected on Magee Peak in 1932. A total of 318 specimen records are databased.

My intention is to complete a florula of the region, for comparison with nearby Lassen Volcanic National Park, which is well documented.

Recognize the Chelonaceae

Classification is a system of coding and organizing objects, be they books, species or whatever. In the library stacks, we expect to find books with largely corresponding subject matter shelved together. Similarly, in a local, regional or continental flora, we expect to find similar plants 'shelved' together. Placement of Penstemon and allied genera in the Plantaginaceae is the funcitonal equivalent of placing floras in with the cookbooks: it does not serve direct discovery.

Users of floras use floras because they want to know the name of a plant. Although polyphylletic, the "Scrophs" served this objective. Find a tubular corolla, often brightly colored, often 2-lipped, capsular fruit plant and fish about in the key to Scrophs...

Taxonomy and classification are often incorrectly equated, to do so is to conflate. Taxonomy is a system of classification, A taxonomic system is a particular type classification: a classification based on phyllogenetic relatedness is one system. An alternative 'system' often used in flora guidebooks is flower color.

Placement of Penstemon, Collinsia, Kecklilla, Tonella (California plants) and others (Chelone, Chinophila, Russelia,
Tetranema etc) in the Plantaginaceae, along with dozens upon dozens of equally diverse tribes and genera creates a discordant grouping. An expanded Plantaginaceae is a discordant grouping. Recognizing Plantaginaceae becomes difficult. What key feature does one use to equate these plants? In my opinion, none!

The point: in a regional flora, if one is such dire need to use a phyllogenetic system, why be bashful? After all, we no longer grumble about splitting up artificial, aggregate genera (vis Stipa into many genera) although sometimes revert to these aggregates.

Penstemon is a member of the Chelonaceae Martinov, containing Chelone, Chinophila, Collinsia, Keckiella, Pensteomon, Russelia, Tetranema, Tonella and Uroskinnera. All are New World, bird or bee pollinated, large showy flowered (or for Collinsia, unusual in their "pseudo-papillanceous flowers). Placement of Brookea auriculata of Asia is the only outlier in that genus should it belong here.

The problem with an expanded Plantaginaceae is that is a library where no two books shelved next to one another share much information. Make families that are closely related lineages consisting of groupings of genera and their radiant species. The expanded Plantaginaceae is not a natural family.

California botanists, recognize the Chelonaceae.

Brodiaea matsonii in cultivation

Brodiaea matsonii has been maintained in cultivation since 1997. I was originally given a single one-gallon pot by Gary Matson which contained about 30 or so corms with leaves present. In growing this plant, its tendency to propagate vegetative became quickly apparent. From the original lot of corms, by the onset of the first summer in cultivation, many young corms had begun to form from offests. Vegetative reproduction is not uncommon in many native California liliaceous endemics: several taxa of Brodiaea do this, others do not.

The offset corms arise at the ends of short (10 cm or so) threadlike structures (rhizomes?), which terminate in a new small corm, which then puts up a leaf. A second season of growth, and this corm is sufficiently large to itself produce more offsets. Larger corms, about 3 yr, flower.

In the space of three or so years, the original pot was packed, and so it was divided when the corms became dormant in late summer. Replanted, that original pot became several one-gallon pots. In 2007, one of these was referred to Dr Robert Preston, a botanist familiar with the taxonomy of Brodiaea, whom has recently described California’s newest, and perhaps most-narrow endemics.

In cultivation in Aptos, Brodiaea matsonii flowers readily in cultivation in pots. The plants have been maintained just as they were given to me: one gallon plastic pots, about 2/3rds full with potting soil mixed with pea gravel.

More on Brodiaea matsonii soon...
