Aquatic Vascular Plants of New England: 

 Part 8. Lentibulariaceae 



by 

 G. E. Crow and C.B. Hellquist 



INTRODUCTION 



This is the eighth in a series of reports on the aquatic and wetland 

 flora of New England. These reports are intended to aid conservation- 

 ists, fish and game personnel, consultants, botanists, and students in 

 the identification of aquatic plants. The coverage is strictly New 

 England but is of value throughout the northeast. Data have been 

 gathered from herbaria in New England and from personal field work. 



Chemical data presented represent samples from many waters 

 throughout New England. The alkalinity readings are total alkalin- 

 ity, expressed as milligrams per liter (mg/1) CaCOa. The number of 

 observations is given in parentheses following alkalinity and pH 

 values. Since pH and alkalinity vary greatly during the day, the 

 values are only indicative of the water quality. 



The rare and endangered plant lists referred to are those prepared 

 for each of the six New England states by the New England Botanical 

 Club in cooperation with the United States Fish and Wildlife Service, 

 Office of Endangered Species, Newton Corner, MA (RI — Church and 

 Champlin, 1978; MA — Coddington and Field, 1978; VT — Country- 

 man, 1978; ME — Eastman, 1978; CT - Mehrhoff, 1978; NH - Storks 

 and Crow, 1978). Taxa indicated as rare, threatened or endangered for 

 the entire New England Region are also noted (Crow et ai, 1981, 

 Rhodora 83: 259-299.) 



We invite comments and/or criticisms on this treatment. Infor- 

 mation on any species omitted or any additional localities will be 

 welcomed. If anyone is interested in specific localities of any of the 

 species indicated on the dot maps, please contact us.
