Distribution map for Lysimachia hybrida

Updated 5/15/2018. Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.


Swamp candles is known only from very old records noting that this species occurred in moist ground near lakes. It was last documented in the state in 1927.

Natural Community Types


For each species, lists of natural communities were derived from review of the nearly 6,500 element occurrences in the MNFI database, in addition to herbarium label data for some taxa. In most cases, at least one specimen record exists for each listed natural community. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Natural communities are not listed for those species documented only from altered or ruderal habitats in Michigan, especially for taxa that occur in a variety of habitats outside of the state.

Natural communities are not listed in order of frequency of occurrence, but are rather derived from the full set of natural communities, organized by Ecological Group. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon.

Associated Plants

Few collection data are known for Michigan. In the Chicago region, this species occurs in bottomlands and marshy areas with such associates false nettle, tickseed, fowl manna grass, buttonbush, rice cut-grass, pin oak, mad-dog skullcap, bugle weed, water smartweed, and southern blue flag.


The primary need for this species at present is a status survey to determine if extant populations can be discovered. If found, protection of hydrology is likely to be important.

General Survey Guidelines

Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
