EEMAEKS AND OBSERVATIONS. 



Thalictrum anemonoides, Mx. A double-flowered form with 

 the stamens transformed into oval greenish petaloid leaflets was de- 

 tected near Coeymans, Albany county. Prof. J. S. St. John. 



Nuphar ad vena, Ait. A variety (near var. var legato) with large 

 partly purplish flowers is not rare in the lakes and sluggish streams of 

 the Adirondack wilderness. The flower when pressed open is nearly 

 three inches in diameter. A very noticeable variety occurs in Forked 

 Jake, Adirondack mountains, where it was first detected by Prof. P. 

 A. Puissant. It may be characterized thus: Var. liybrida. Sepals 

 six, rarely five, subequal, the three exterior often tinged with red ; 

 petals twelve to fourteen, generally thirteen, about as long as the con- 

 tiguous stamens ; stigmatic disk red, umbilicate, ten to thirteen -rayed, 

 the margin slightly crenate ; leaves small, with a paler greenish dash 

 beneath on each side of the midrib, the sinus usually open ; petioles 

 flattened on the upper side. This variety grows in water four to 

 eight feet deep in close proximity to a patch of 2fup7iar lutea var. 

 pumila (JV. Kalmiana, Pursh.) In size and character it is intermedi- 

 ate between this and the ordinary form of N. 'odvena. It is smaller 

 in all its parts than the latter and larger than the former and appears 

 very much as if it might be a hybrid between them. The number of 

 the sepals connects it with N. adveha, but the disk of the stigma allies 

 it more closely with JSF. Kalmiana. The flowers when outspread are 

 nearly two inches across. When fresh they have an agreeable spicy or 

 aromatic odor. In this respect they differ from our common forms of 

 both species. 



Nymphaea odorata, Ait. In stony ponds, Adirondack mountains, a 

 small form was found in which the outspread flowers are scarcely two 

 inches in diameter. Also a form in which the outer petals are tinged 

 with pink. 



Cardamine hirsuta v. sylvatica, Gr. Thin dry soil covering rocks. 

 Edmonds ponds. 



Vitis aestivalis, Mx. A form with the leaves deeply and angularly 

 five-lobed occurs in Sandlake. The foliage at first sight appears as if 

 it had been eaten by insects. 



Primus pumila, L. Sandy shore near the outlet of Long lake, 

 Adirondack mountains ; the prostrate trailing form fruiting abun- 

 dantly. 



Rosa lucida, Ehrh. To this species I refer a very marked form oc- 

 curring on the slopes of Mt. Defiance and near Westport, Essex county. 

 The stems are armed, especially toward the base, with very numerous 

 unequal, bristly prickles, the calyx lobes are scarcely gladular-bristly 

 and the smooth fruit is ovate or elliptical. 



Ribes rotundifolium, Mx. Mt. Defiance. A form with leave's mostly 

 about half an inch broad, as if starved and unthrifty, yet fruiting 

 abundantly.
