1920] Wiegand,—Additional Notes on Amelanchier 149 
In the summer of 1912 Professor M. L. Fernald collected a quan- 
tity of a strange Amelanchier on the Magdalen Islands, and in 1914 
in western Newfoundland. "The writer is inclined to agree with Fer- 
nald that this is an undescribed species of the region about the Gulf 
of St. Lawrence, a similar plant having been secured by Fernald in 
Gaspé Co., Quebec. It inhabits lime barrens or strongly calcareous 
gravelly shores and swamps, and may be described as follows: 
A. Fernaldii, sp. nov., humilis 3-6 dm. alta diffusa stolonifera 
subcaespitosa, foliis ad anthesin semiexpansis glabris et viridibus, 
maturitate submagnis 5-8 cm. longis, late elliptico-oblongis vel 
subobovatis, basi rotundatis vel subcordatis, apice subacutis, mar- 
gine e basi ad apicem dentibus mediocribus acute serratis, laminis 
glabris subtus paullo pallidioribus irregulariter venosis, petiolis 
tenuibus sparce villosis; racemis multi- vel pauci-floris glabris 
laxis, pedicellis inferioribus 1.5-3 cm. longis, hypanthio submagno 5 
mm. lato campanulato, sepalis 3-4 mm. longis lanceolato-deltoid- 
eis irregulariter divaricatis vel recurvatis conspicuis glabris vel intus 
subtomentosis, petalis liguliformibus 1-1.5 cm. longis, ovario ad 
apicem tomentoso, fructo atropurpureo succulento, tubo hypanthii 
paulo evoluto, pedicellis fructiferis saepe 3-4 cm. longis. Western 
Newfoundland and the Magdalen Islands to the coast of Quebec, and 
apparently some distance up the St. Lawrence river. NEWFOUND- 
LAND: limestone tableland of Table Mountain, Port à Port Bay, 
1914, Fernald & St. John, no. 10840 & 10842. MAGDALEN ISLANDS: 
Grindstone, 1912, Fernald, Long & St. John, no. 7592 (TYPE in Gray 
Herb.), also nos. 7589 & 7590, also Fernald, Bartram, Long, & St. John, 
no. 7586; between East Cape and East Point, Coffin Island, 1912, 
Fernald, Bartram, Long & St. John, no. 7587. QUEBEC: banks of 
the Grand River, Gaspé Co., 1904, Fernald; Isle aux Coudres, 1917, 
Bro. M. Victorin, no. 4318 (apparently this species). 
This plant at first glance suggests a hybrid between A. laevis and 
A. stolonifera, but A. stolonifera is not a plant of lime barrens, and has 
not been found in the region from which this plant was collected. 
Moreover the leaves of our plant are never hairy. It suggests also 
a combination of A. Bartramiana and A. laevis, but the leaves are 
too blunt. The plant wherever found gives the impression of being 
the same, and seems to form a definite unit, not a fluctuating hybrid. 
A. Fernaldii is not to be confused with A. sanguinea, var. gaspensis 
which has coarse teeth, more parallel veins, and a more pronounced 
hypanthium-tube.
