for the loan of much additional material, and to a great many botanical 
friends who have sent me specimens of interest. Mr. C. D. Beadle 
gave me the privileges of the Biltmore Herbarium and ‘very kindly 
aided me in the examination of the southern species. Mr. W. W. 
Ashe most kindly made a three days' trip to allow me to see his 
Crataegus herbarium. I have also to thank Dr. Marshall A. Howe 
for numerous translations of the descriptions of the older species.

AMERICA.

М. І. FERNALD. 
DENTARIA LACINIATA Muhl., var integra (Schulz), n. comb. Carda- 
mine laciniata (Muhl.) Wood, var. integra Schulz in Engler's Bot. 
Jahrb. xxxii. 349 (1903).— A rather local extreme, having the leaves 
strictly ternate; the lateral leaflets entire or slightly toothed, but not 
cleft. Known only from western New York to Illinois. 
GAYLUSSACIA BACCATA (Wang.) C. Koch, forma LEUCOCARPA 
(Porter) Fernald, RHopora, x. 53 (1908). My attention has been 
called by several friends to a clerical error by which, in the original 
publication of this combination, I credited Wangenheim instead of 
C. Koch with the publication of G. baccata. G. baccata (Wang.) C. 
Koch, Dendrol. ii. pt. 1, 93 (1872) was based upon Andromeda baccata 
Wang., Beitr. Holzger. iii. t. 30, fig. 69 (1787). 
TEUCRIUM CANADENSE L., var. littorale( Bicknell), n. comb. T. 
littorale Bicknell, Bull. Torr. Bot. Cl. xxviii. 169 (1901).— A lower 
stiffer and usually more simple plant than the inland 7. canadense, 
but clearly passing to it in rich soil. In their most extreme develop- 
ments the two plants are easily distinguished; the var. littorale of 
coastal beaches having the upper surface of the leaves papillose- 
roughened beneath the fine appressed pubescence, while the plant of 
less exposed situations is, as we should expect, thinner-leaved and 
with less developed papillae.
