Tyre in Gray Herbarium, collected on open roadside, Woodford,

White-flowered forms of the other closed Gentians undoubtedly 
occur but so far as the writer has seen they have been collected only 
in this species and in G. Andrewsii (forma albiflora Britton). 
VIII. SOME NEW OR CRITICAL PLANTS OF EASTERN NORTH 
AMERICA. 
HreRocHiLoa oporata (L.) Wahl., var. FRAGRANS (Willd.) Richter, 
forma Eamesii, n. f., panicula elongata 2—4 dm. longa, ramis paucis 
remotis. 
Panicle elongate, 2—4 dm. long, with few elongate branches.— Con- 
NECTICUT: border of cultivated field beside salt-marsh, Fairfield, 
May 13, 1910, E. H. Eames, no. 8339; field bordering salt-meadows 
in rich soil, May 27, 1914, E. H. Eames, no. 8734 (TYPE in Gray Herb.). 
The common plant of boreal North America and the northeastern 
coast is not true H. odorata of the Old World and of the Rocky Moun- 
tain region, but is a pronounced variety, so well marked that by 
Willdenow, Pursh, Roemer & Schultes and other authors early in the 
19th century it was considered a distinct species: Holcus fragrans 
Willd. Sp. Pl. iv. 936 (1805), Pursh, Fl. Am. Sept. i. 78 (1814); Hiero- 
chloa fragrans (Willd.) R. & S. Syst. ii. 514 (1817). Willdenow, 
however, surmised that it might be a variety, saying: “ Simillimus 
praecedenti [Holcus odoratus) differre tamen videtur, calyce floribus multo 
longiore, corollis margine non villoso-ciliatis et flore hermaphrodito apice 
laevi. An varietas ? W.” In western North America where true 
Hierochloa odorata abounds the two varieties clearly intergrade as 
they do in northern Europe. 
Dr. Eames’s extreme form of var. fragrans was distributed as
