 Summit of Pipestone Pass. Rocky Mt Park, No. 64,412, 

 1904. {John Macotin) Descr.bed from specimens collected 

 by Mr. W. C. McCalla at Banff in 1899. This species belongs 

 to the D. incana group but differs from that species in the 

 elongated peduncle, long ped'cels, short pubescent pod and 

 large petals. 



Arabis Collinsii, Fernald, Rhodora. vii : 32. 



"Qjickly distinguished from A. HolboeUii by the loose 

 hispidulous pubesetice of the stem and pedicels, the smaller 

 flowers and the very sle der acuiish pods." Collected on dry 

 limestone conglomerate ledges, headland in the harbour of 

 Bic, Rimouski Co , Que , July 18, 1904 {J. F. Collins & 

 M. L. Fernald.) 



Drosera rotundifolia, L, var. comosa, Fernald, Rhodora, viirg. 

 A dwarf variety of Hie common sundew with crimson or 

 roseate instead of white flower? ; the petals are sometimes 

 foliaceous and the carpels are developed in maturity into 

 green, glandular broadly obovate or oblate petioled leaves. 

 Collected in abundance near the mouth of Grand River, Gasp^ 

 Co., Quebec, in 1904 by Messrs. J. F. Collins, ML. Fernald 

 and A. A. Pease. An examination of a large series of speci- 

 mens of D. rotundifolia in our herbarium shows nothing 

 approaching this variety.
