482 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. 



On page 362, before Adenostegia ramosa, insert: 



* Euphrasia Americana Wettst. Men. 127 [111. Fl. 3: 182] ; Eu- 

 fhi'asia officinalis Gray, Syn. Fl. 2' : 305, in part. 



A small plant, usually less than i dm. high, somewhat hairy, but 

 not glandular, with round-ovate serrate leaves, generally less than 

 I cm. long, and small nearly white or purplish-tinged very irregu- 

 lar flowers. 



Montana: Between Forks of Cutbank Creek, 1897, R. S. Wil- 

 liams, io8g. 



On page 366, before Rhinanthus Crista-galli, insert : 



* Pedicularis Oederi \^ahl, Hornem. Dansk. Oek. Plantel. Ed. 2, 580. 



Like P. versicolor Wahl., but the corolla larger, yellow; galea 

 less arcuate, without beak or teeth at the apex. The plant is about i 

 dm. high, slightly arachnoid-hairy when young, glabrous in age; 

 leaves pmnately divided with rounded crenate lobes. The Montana 

 specimen has slightly larger corollas than those collected by Prof. 

 Boeck in Norway, 1869, and by J. M. Macoun on St. Mathews 

 Island, Alaska, 1891. 



On mountains, at an altitude of 3000-3300 m. 



Montana: Granite Range, 1899, Peter Koch. 



On page 367, before Utricularia vulgaris, insert: 

 *Pinguicula vulgaris L. Sp. PI. 17 [111. Fl. 3: 194; Syn. Fl. 2^: 



317]- 



An acaulescent plant with blue bilabiate and straight-spurred sol- 

 itary flowers on a scape, and oblong thick basal leaves with the 

 upper surface covered wath a viscid secretion. In bogs. 



Montana : Between Yellow Mountain and Lower St. Mary's 

 Lake, 1897, R. S. Williams, iog2, in part; Divide Mountain, 1897, 

 logz, in part (the latter specimen belongs to the form P. macroceras 

 Willd., with large flowers and thicker spur, and may be distinct). 



On page 378, instead of Laurentia carnosula, read : 



Porterella carnosula (Hook. & Am.) Torr. Hayden, Rep. 1872 : 488 ; 



Laiirentia carnosula, etc. 



The American plant is quite different from the South European 

 and African types of Laurentia, and it is therefore better to regard it 

 as belonging to a different genus.
