474 SUPPLEMENT. 



RESEDACE^. 



1. RESEDA, Tourn. 



R. liJtea, L., p. 188. For Amer. distrib. substitute, Locally established in fields, &c., chiefly 

 in Atlantic States, but said to extend westward as far as Michigan. 



CISTACE^. 



In the second line of the generic key strike out the word " nerviform." 



1. HELIANTHEMUM, Tourn. In the generic character, for "strictly 

 parietal," read, parietal or septiform. 



H. Canadense, Michx., p. 190. Common in E. Massachusetts and extending northeast- 

 ward to York Co., Maine, Fernald. 



H. arenicola, Chapm., p. 190. The Mississippi occurrence appertains to the following 

 species. 



H. Nashi, Britton, p. 190. This species on further investigation proves to have heteromor- 

 phous flowers and should therefore be placed in tlie preceding division of the genus. Many 

 of its cleistogamous flowers have 2-valved ajiparently bicarpellary fruits. 



2. HUDSONIA, L. 



H. montana, Nutt., p. 191. In line 4, for " Table Mountain," read, Table Rock.

L. intermedia, Leggett, p. 193. A dubious form, somewhat intermediate between this 

 species and L. stricta, and mentioned under the latter (on p. 193) as occurring in Maine, is 

 also found in the White Mountains. It is the recently proposed L. juniperina, Bicknell, 

 Bull. Torr. Club, xxiv. 88, but lacks satisfactory characters. 



VIOLACE^. 



1. ViOLA, Tourn. For recent literature, see Greene, Pittonia, iii. 33-42,

 Holzinger, Contrib. U. S. Nat. Herb. iii. 214 ; Britton, Bull. Torr. Club. xxiv. 

 92. It may be noted that nearly all the recently proposed or reinstated species 

 represent plants familiar to Dr. Gray at the time of his revision, and that their 

 altered presentation is largely due to differing views as to the taxonomic value or 

 scope of the term species. 



V. pedatifida, Don, p. 196. Extends eastward to Marblehead Isl. in Lake Erie, near San- 

 dusky, Ohio, E. L. Moseley.
