PRELIMINARY INDEX OF UTAH VASCULAR PLANT NAMES

Abstract.— Presented herein is an index to vascular plant names of Utah. The names are arranged in alphabetical order by , species, and infraspecific taxa. Each entry is followed by a bibliographic citation, family name,, rari- ty (whether endemic, rare, or endemic-rare), and origin (whether indigenous, adventive, or adventive-cultivated). Pertinent synonyms are cited beneath appropriate entries. An index of synonyms and a comprehensive bibliography are included.

For many years there has existed a gap in A list of names and authors alone would the plant of Utah—no single treat- have been useful, but bibliographic citations ment has included the names of all plant spe- given for the plant names provide an extra cies known for the state.

These are the names included clouded by lack of information about early the following checklist: introductions in the region. Tentative judg- ments are followed by a question mark. The same is true for adventive species, those which represent inadvertent introductions from other places, especially from the Old World. Cultivated plants are mainly in- troductions, and no attempt has been made to provide an exhaustive list of all plants in this category. Some cultivated plants are nat- uralized and are a part of the continuing flora of the region (i.e., Uhnus piwiila, Ca- talpa speciosa, Ligustnim vulgare, Robinia pseudoacacia, and many others). Others are continuously reintroduced, especially weedy species and those grown as crop plants. Addi- tional ones are known only in greenhouse culture, often as mere curiosities. In any event, cultivated plants seldom are collected. We have listed, mainly, those represented in herbaria and have not distinguished among naturalized and reintroduced species or the greenhouse curiosities.
