Abstract North America is home to approximately 55 species of Ceanothus (Rhamnaceae), more than 30 of them endemic to the biodiversity hotspot known as the California Floristic Province. Although several species of Ceanothus are widespread in North America, most of the species are micro-endemics, known from a small number of occurrences and generally associated with special ecological conditions. As botanical exploration of North America continues, it is expected that more such micro-endemics…

Limited hybridization across an edaphic disjunction between the gabbro-endemic shrub Ceanothus roderickii (Rhamnaceae) and the soil-generalist Ceanothus cuneatus.
There is little genetic exchange between the focal species across an edaphic disjunction, despite the absence of prezygotic barriers, implying that soil conditions, as well as other extrinsic factors, should be considered as forces that may restrict hybridization and gene flow in Ceanothus, influencing local adaptation and speciation.
A Newly Described Serpentine-Endemic Ceanothus (Rhamnaceae) From Coastal Marin County, California
Ceanothus decornutus differs in a number of ways from C. jepsonii and suggests relationships to other northern San Francisco Bay species.
A Taxonomic Conspectus of Ceanothus Subgenus Cerastes (Rhamnaceae)
To aid research in this diverse and ecologically important group of plants, a taxonomic conspectus is presented, including formal recognition of Cerastes at the rank of subgenus, and recognition of all infraspecific taxa at theRank of variety.
Arctostaphylos Myrtifolia, Its Biology and Relationship to the Problem of Endemism
The endemic plant is limited to only certain outcrops of an Eocene laterite in the Sierra Nevada foothills near Ione and to a kaolin—altered rhyolite and an acid sericitic schist eastward at higher altitudes of 500 m.
Gabbro Soils and Plant Distributions on Them
Abstract Gabbro is a mafic rock with many species that do not occur on soils of granitic or ultramafic rocks. Although some gabbro soils harbor many unique or endemic species, others do not, as
Any experiment may be regarded as forming an individual of a “population” of experiments which might be performed under the same conditions. A series of experiments is a sample drawn from this
Herbaria are a major frontier for species discovery
It is suggested that, of the estimated 70,000 species still to be described, more than half already have been collected and are stored in herbaria and effort, funding, and research focus should be directed as much to examining extant herbarium material as collecting new material in the field.
