54 Rhodora [MARCH 
1.5-3.5 сш. long, 7—17 mm. wide, submembranaceous, glabrous, 
somewhat lustrous, the veins prominently reticulate, the fine and 
numerous appressed teeth spinulose: flowers axillary, solitary, on 
peduncles 3-5 mm. long: corolla ellipsoid-urceolate, pink, 6 mm. 
long, 4-5 mm. wide: berries globular or pyriform, deep blue-black, 
with a bloom, 7-9 mm. long.— QUEBEC, abundant in Gaspé County, 
in subalpine and alpine districts on the hornblende-schist of Mt. 
Albert, and on the granitic area of Table-top Mt. Type material, 
in flower and young fruit, collected on hornblende-schist or in the al- 
luvium of an alpine brook, Allen's Ravine, north slope of Mt. Albert, 
July 26 and 28, 1906 (Fernald & Collins, по. 242); in mature fruit, 
on Table-top Mt., August 9, 1906 (no. 688). Also represented in the 
Gray Herbarium by nos. 684, 685, 687, 689, and 690. Associated in 
the subalpine forests and ravines with V. ovalifolium Sm. and V. 
caespitosum Michx., ordinarily in more sheltered situations than V. 
uliginosum L. and V. pennsylvanicum, var. angustijolium (Ait.) Gray. 
Nearest related to the northwestern V. membranaceum Dougl., which 
has the paler branches somewhat angled, the larger leaves paler be- 
neath, and the larger corolla depressed-globose. 
CENTAURIUM spicatum (L.), n. comb. Gentiana spicata L. Sp. 
230 (1753). Erythraea spicata Pers. Syn. i. 283 (1805).— The little 
group of plants known as Centauries were very generally called by 
pre-Linnean botanists Centaurium, but in the Ist edition of the 
Species Plantarum Linnaeus placed them under Gentiana. ln 1790, 
Necker separated them as Erithrea (often spelled Erythraea) and they 
have subsequently borne that name. Prior to Necker's publication, 
however, as recently pointed out by Messrs. Britten & Rendle, the 
old name Centaurium had been clearly used by Hill in his British 
Herbal (1756), and consequently this historic name must be main- 
tained for the genus. In eastern America we have two other species: 
CENTAURIUM texense (Griseb.), n. comb. ÆErythraea texensis 
Griseb. ex Hook. Fl. Bor.-Am. ii. 58 (1838) and Gen. et Sp. Gent. 
39 (1839). 
CENTAURIUM calycosum (Buckl.), n. comb.  Erythraea calycosa 
Buckl. Proc. Acad. Phila., 1862, 7 (1863). 
NyYMPHOIDES lacunosum (Vent.), n. comb. | V illarsia lacunosa Vent. 
Choix des Pl. 9 (1803). Limnanthemum lacunosum Griseb. Gen. et 
Sp. Gent. 347 (1839).— Hill, again, in 1756 clearly defined the Euro- 
pean yellow-flowered Floating Heart as Nymphoides, fourteen years
