All the kingdoms of eukaryotes, including Protista (Protoctista), Fungi, Plantae and Animalia, are placed in the domain Eukarya. Each scalelike leaf bears a dorsal gland that exudes a resin droplet (red arrow). In fact, some botanists now consider the Piute cypress to be a subspecies of the Arizona cypress and have named it C. This species typically grows on outcrops of serpentine in the Coast Ranges of central and northern California.

The large molecular differences between the majority of prokaryotes in the kingdom Monera and the archaebacteria warrants a separation based on categories above the level of kingdom. Division (Phylum) Proteobacteria: N-Fixing Bacteria Division (Phylum) Cyanobacteria: Blue-Green Bacteria Division (Phylum) Eubacteria: True Gram Posive Bacteria Division (Phylum) Spirochetes: Spiral Bacteria Division (Phylum) Chlamydiae: Intracellular Parasites 2. Interior cypress species such as this one typically have glaucous, resinous foliage, presumably an adaptation to dry, arid habitats. Foliage and pollen cones of the Smooth-bark Arizona cypress (Cupressus glabra) [Syn. Serpentine is a shiny rock with a waxy luster and feel.

Luna was an integral part of my career and I would not have succeeded without her.

We have lost a great performer and an even greater person.

These remarkable organisms are now placed in the domain Archaea. Left: Monterey cypress (Cupressus macrocarpa) in Point Lobos State Park on the coast of central California. nevadensis) in the Piute Mountains, with Lake Isabella and the snow-covered Sierra Nevada in the distance.

Other prokaryotes, including eubacteria and cyanobacteria, are placed in the domain Bacteria. The Piute cypress are more drought resistant, with gray (glaucous), glandular (resinous) foliage similar to the Arizona cypress.

Systematists have devised a classification level higher than a kingdom, called a domain or "superkingdom," to accomodate the archaebacteria. The scalelike leaves of Tecate cypress are green and without dorsal resin glands.

Some members of the Kingdom Fungi (in the fungal classes Ascomycetes and Basidiomycetes) are associated with algal cells of the Kingdom Protista (in the algal division Chlorophtya) and/or prokaryotic cyanobacteria of the Kingdom Monera. Junipers actually produce small cones with fleshy, fused scales bearing one-several seeds.

This complex symbiotic, mutualistic relationship is called lichen. Podocarpus is a dioecious species, with separate male and female trees in the population.

Known as the Ediacaran biota, these deposits date back 600 million years ago. Minute female cones are composed of 2-4 reduced scales, but usually only one scale bears an ovule that matures into a seed.

Some of these ancient protoctists may have been ancestral to certain animal and plant phyla. There is little resemblance to a cone in the mature seed.
