Resembling S. nivalis, but the rosette-leaves more narrowly cune- 
ate-obovate and more gradually narrowed to the broad petiolar base, 
acute at summit, 1.5-3 em. long, 5-9 mm. broad, acutely dentate 
above the long-cuneate base: scape solitary, slender, 1-7 cm. high, 
minutely glandular-pilose: inflorescence spicate-racemose, in fruit 
1-2.7 em. long, 3-5-flowered: lower bracts oblong or ovate, acute, 
5-8 mm. long, exceeding the flowers: pedicels 2-3 mm. long, pilose: 
ealyx-tube green, hemispherical, 1.5-2.5 mm. high; calyx-lobes 
oblong or narrowly deltoid, reflexed in fruit, 1.8-2 mm. long; petals 
white, lanceolate or narrowly elliptical, acute or subacute, 1.5-2 mm. 
long, 0.5-0.8 mm. wide: filaments filiform-subulate, purplish, 1-1.2 
mm. long: capsules greenish or pale-brown, 4 mm. long; the follicles 
with very short divergent beaks.— QueBEc: very local, in sheltered 
pockets on abrupt western calcareous slopes, altitude 1000-1100 
meters, Table-top Mountain, Gaspé County, August 5 and 12, 1906,

Distributed as S. nivalis, from which it differs in many characters; 
S. nivalis having the leaves more rounded-oblong to round-obovate 
and narrowed to a more definite petiole and commonly much broader 
(0.7-3 cm.). The inflorescence of S. nivalis is usually more numerously 
flowered, varying from spiciform to corymbiform; its calyx-lobes are 
from 2-3 mm. long, spreading in fruit; its oblong petals are rounded at 
summit and 1.5-2.3 mm. wide; and its capsule is much larger, 5-7.5 
mm. long. On Table-top Mountain the extremely local S. gaspensis 
was growing with other very localized species, Carex rupestris Allioni, 
Pyrola grandiflora Radius, Pedicularis flammea L., Campanula uni- 
flora L. and Senecio pauciflorus Pursh. 
SAXIFRAGA NIVALIS L., var. labradorica, n. var., panicula corym- 
biformi laxa; floribus plerumque graciliter pedicellatis, pedicellis 3-10 
mm. longis. 
Panicle loosely corymbiform; the flowers mostly on slender pedicels 
3-10 mm. long— LABRADOR: Rama, August 20-24, 1897, J. D.

This is apparently the plant intended by Small in the North A meri- 
can Flora as Micranthes tenuis,! based upon Saxifraga nivalis B. tenuis 
Wahlenb. Fl. Lap. 114 (1812). Wahlenberg’s variety went back to 
earlier species of Rottboel and of Martens which prove to be merely 
forms of S. nivalis in which the lower branch of the inflorescence is
