ROBINSON. — BOTANICAL NOTES. 329 



to the greater leDgth 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. 



Dalea neglecta. Branches slender, terete, glabrous, glandular- 

 punctate : leaves smooth, 1^ — 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 and 

 veinless above, glaucous, glandular-punctate and 1-nerved beneath: 

 peduncles very slender, equalling or exceeding the curved loosely- 

 flowered spike (H inches in length) : flowers 2^—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 Duges (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 Pennyslvanica, 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 

 greenish or yellowish green. As the anthers are bright orange, the 

 dark red or crimson petals give to the flowers a much more striking 

 contrast of color, doubtless correlated with insect pollination. So far 

 as observed, the specimen in question presented no other differences 

 from the typical form. 



Aster paucicapitatus. Stems several, simple, flexuous, leafy to 

 the summit, ribbed, somewhat pubescent, 10 inches to lh feet high: 

 leaves elliptic-oblong, obtuse or obtusish, mucronulate, sessile by a 

 scarcely narrowed base, finely and somewhat glandularly pubescent, 

 9-16 lines long, 3-5 lines broad, erect or ascending: heads usually
