, a journal published by his friends the Brandegees, Jones began his own journal in the 1890s. Writing and publishing his own Contributions to Western Botany allowed Jones more freedom to write whatever he saw fit. Though Jones used the journal primarily to publish taxonomic notes, descriptions of new species, and accounts of expeditions, he also took advantage of the opportunity to include reviews of other botanists’ publications, which oftentimes were highly critical. Later in his career Jones began publishing a series of biographical sketches on prominent botanists with whom he was familiar. According to Lee W. Lenz in his biography of Jones,
Sketches in his “Botanists I have known” series can be
divided into four groups: those whom he admired as both individuals and for
their work; those who he admired, or at least accepted as individuals but whose
work he disapproved of; those he disliked as individuals but the worth of whose
botanical contributions he acknowledged; and finally those whom he both
disliked as individuals and whose work he disapproved.(Lee W. Lenz. Marcus E. Jones: Western Geologist, Mining Engineer & Botanist. Claremont: RSABG, 1986.)
Jones published Contributions intermittently throughout his career up until his death. The final issue, Contributions to Western Botany, No. 18, was published posthumously by his daughter Mabel Broaddus. The majority of the text from all 18 issues is available online at the Biodiversity Heritage Library.
