This study presents a phytogeographical analysis of the native vascular flora of Connecticut. There are approximately 2,600 taxa of vascular plants reported from Connecticut. Almost 900 of these are non-indigenous. Of the remaining 1700, those that exhibit a restricted range in Connecticut are considered. Connecticut specimens from five regional herbaria and extensive field work are the basis for this study. Species distributions globally and within Connecticut were evaluated in order to identify reoccurring patterns. Groups of species with similar ranges in Connecticut constitute a floristic pattern. Six primary florist patterns were identified. In addition, 17 floristic sub-patterns within the primary patterns were identified. Probable reasons for species occurrence within each floristic pattern are discussed. Floristic regions for Connecticut are delineated. Species distribution maps are included for each floristic pattern. A brief history of floristic botany in Connecticut is included. A plea is made for continued field work and documentation of changes within the flora. ^
