congeneric with Helianthemum canadense and H. majus. Other dis- 
tinctions, in the embryo, etc. have been suggested, but it is extremely 
doubtful if these have been checked in all our species. At least, the 
writer, finding himself unable with his present knowledge of the group 
to maintain Crocanthemum for the plants of northeastern America, 
thinks it better to treat the plants as belonging to a subgenus under 
Helianthemum, a course which has commended itself to many scholarly 
students in the past. The low early-flowering species of the coastal 
region of southern New England and New York should then, as a 
Helianthemum, be called 
HeELIANTHEMUM dumosum (Bicknell), n. comb. Crocanthemum 
dumosum Bicknell, Bull. Torr. Bot. Club, xl. 613 (1913).

GLANDULARITY ON VERONICA ANAGALLIS-AQUATICA L.— The seventh 
edition of Gray’s Manual describes Veronica Anagallis-aquatica L. 
as smooth. However, specimens collected in Sheffield and Stock- 
bridge, Massachusetts, have the stem and branches of the inflorescence 
thickly clothed with glandular pubescence. Three specimens in the 
Gray Herbarium from England, Bohemia, and France are smooth, 
while one from the Azores is glandular. In America the glandular 
form has been collected at Tinmouth, Vermont; Newark, New York; 
Lancaster, Pennsylvania; and Berkshire County, Massachusetts. 
The smooth one, on the other hand, has been found in Ipswich, Mas- 
sachusetts, in New Jersey, Pennsylvania, Missouri, New Mexico, 
Arizona, Oregon, and Assiniboia. A specimen from Virginia has the 
inflorescence glandular and the stem smooth. Further collection 
and examination of material of this species is needed to determine 
the constancy, geographic bearing, or taxonomic significance of these 
differences. In any event it appears that the description in the 
Manual should read “smooth or glandular.” — RALPH HOFFMANN,
