- ROBINSON. — BOTANICAL NOTES, 829 
to the greater length of the season. As to the size of the flowers, a 
series of specimens collected at Mt. Desert by Mr. Redfield and Mr. 
Rand conclusively shows that this is largely a function of the season, 
the autumnal flowers being much smaller than the earlier ones, indeed 
far smaller than those of the southern form. The shape of the cap- 
sule gave promise of furnishing a good character, but the difference 
between globose and ovoid is not a sharp one, and on examination it 
proves that subglobose capsules occasionally occur in the White Moun- 
tain plant, and even in the few Greenland plants which could be ex- 
amined the capsules were found to vary to ovoid, so that no sharp 
distinction can be founded upon this character. 
Datea neGiecta. Branches slender, terete, glabrous, glandular- 
punctate: leaves smooth, 14-2 inches in length; leaflets 5-7 pairs 
and odd one, 4—5 lines long, elliptic or oblanceolate, petiolate, obso- 
letely crenate, rounded at the apex, acute at the base, smooth an 
Veinless above, glaucous, glandular-punctate and I-nerved beneath: | 
peduncles very slender, equalling or exceeding the curved loosely- 
flowered spike (13 inches in length): flowers 24-3 lines long, spread- 
ing or reflexed upon very short pedicels: calyx turbinate, strongly 
ribbed with yellow glands and covered with very short upwardly ap- 
Pressed or rather incurved hairs; teeth lance-linear, acute, inflexed, 
nearly equalling the tube: corolla in dried specimens bright purple. — 
Collected at Guanajuato, Mexico, by Prof. Alfred Dugés (no. 2576). 
Habit nearly of D. nutans, Willd. The peculiar pubescence of the 
calyx appears rather exceptional in the genus, being in most species 
Straight, silky or lanate. 
SAXIFRAGA Pennysivanica, L. A specimen of this species, col- 
lected at Royalton, Vt., with deep red petals, has recently been received 
at the Gray Herbarium from Miss Emily P. Robinson of Manchester, 
N.H. A hasty search in the literature of the species has failed to 
show any record of this variation, the petals being always described as 
Sreenish or yellowish green. As the anthers are bright orange, the 
dark red or crimson pétals give to the flowers a much more striking 
“ontrast of color, doubtless correlated with insect pollination. So far 
. observed, the specimen in question presented no other differences 
om the typical form.
