It is endemic to Tulare County, California, where it is known only from Chimney Creek in the southern Sierra Nevada east of Lake Isabella. It occurs in woodland habitat on sandy granitic substrate.

Campanula robinsiae is a rare species of flowering plant in the bellflower family known by the common names Brooksville bellflower, Robins' bellflower, and Chinsegut bellflower. It is endemic to Florida, where it is known from four or five occurrences in Hernando and Hillsborough Counties. Its population has fluctuated throughout the years; at one point in the early 1980s it was feared extinct. Today there are two populations in Hernando County and probably three in Hillsborough River State Park. At the time the plant was listed as an endangered species of the United States in 1989, it was known from three small populations on wet prairies that were threatened by changes in the local hydrology and by pollution. It was also thought to be threatened by vandalism, trampling, and collecting by flower enthusiasts. Cattle grazing and invasion of the habitat by the exotic skunkvine also degrade the habitat.
Campanula piperi is a species of flowering plant in the bellflower family, Campanulaceae. It is native to the Olympic Mountains on the Olympic Peninsula in the U.S. state of Washington. It has also been noted on Vancouver Island, British Columbia.
