ABBREVIATION : MONDIF SYNONYMS : Claytonia diffusa Nutt. [4,5,7] SCS PLANT CODE : MODI3 COMMON NAMES : branching montia TAXONOMY : The currently accepted scientific name of branching montia is Montia diffusa (Nutt.) E. Greene (Portulacaceae). There are no recognized subspecies, varieties, or forms [4,7,11]. LIFE FORM : Forb FEDERAL LEGAL STATUS : No special status OTHER STATUS : The Nature Conservancy ranks branching montia as rare and/or local globally (G3) and imperiled to critically imperiled (S1S2) in the state of Washington [12].

BOTANICAL AND ECOLOGICAL CHARACTERISTICS

SPECIES: Montia diffusa
GENERAL BOTANICAL CHARACTERISTICS : Branching montia is an annual forb diffusely branched from the base with erect stems 2 to 6 inches (5-15 cm) tall. The basal and cauline leaves are alike and are 0.8 to 2 inches (2-5 cm) long. The inflorescence is a terminal panicle. Capsules have one to three seeds that are approximately 0.06 inch (0.15 cm) long [4,7]. RAUNKIAER LIFE FORM : Therophyte REGENERATION PROCESSES : NO-ENTRY SITE CHARACTERISTICS : Branching montia is found on moist sites [4,7]. In California it most often occurs in woodlands and coniferous forests below 3,280 feet (1,000 m) elevation [7]. SUCCESSIONAL STATUS : NO-ENTRY SEASONAL DEVELOPMENT : Branching montia flowers from May to July [7].

FIRE ECOLOGY

SPECIES: Montia diffusa
FIRE ECOLOGY OR ADAPTATIONS : Information regarding the ecological adaptations of branching montia for survival following fire is not available in the literature. Miner's-lettuce (Claytonia perfoliata), a closely related species, colonizes sites following fire by long-lived seeds that are stored in the soil. Miner's-lettuce also mass-flowers in the first postfire years, allowing for secondary colonization by on-site seed [9]. Branching montia often occurs in burned or otherwise disturbed confierous forests [11], and may have similar postfire reproductive patterns.

POSTFIRE REGENERATION STRATEGY : NO-ENTRY
