lata. Our specimens are not even hairy, which the Berlin her- 

 barium specimen, which Witasek saw, evidently is. C. pctiolata 

 is generally perfectly glabrous. In the Rockies, especially in 

 Colorado, are found forms densely pubescent on the lower part 

 of the stem and less so on the leaves. Otherwise I have found 

 no character to separate this form from the typical C. pctiolata. 

 Maybe the author of the monograph has confused under the so- 

 called American C. rotundifolia the hairy form of C peliolata 

 and an undescribed species from Mexico and New Mexico. 



Campanula dubia DC. is the same as C. Scheuchzeri and C. 

 rotundifolia var. arctica of Gray's Synoptical Flora, at least in part. 

 It is more closely related to C. rotundifolia than to C. intercedens. 

 It is usually one-flowered with erect flower buds, with thin broad 

 linear to oblanceolate stem-leaves, and round or rarely reniform 

 basal leaves, large flowers and long sepals. It grows from New- 

 foundland to the White Mountains of New Hampshire. 



Campanida Giesekiana Vest has gone under the name of C 

 Scheuchzeri, C. rotundifolia var. linifolia and var. arctica, and 

 has not been separated from the preceding, but is distinguished 

 from that species as well as from the others of the C. rotundifolia 

 group by the short and broad hypanthium, which in flower is 

 much broader than high. It is usually a low plant, densely leafy 

 below and naked above, usually one-flowered. The lower stem- 

 leaves are often spatulate and obtuse. C. Giesekiana is an arctic 

 plant growing in Europe and Asia, as well as in America, where 

 it has been collected in Greenland, Labrador and on the islands 

 of the Baffin's Bay region. 



Campanula heterodoxa Vest is, according to Witasek, the same 

 as C. rotundifolia Alaskana of Gray's Synoptical Flora, and is a 

 native of Alaska and Eastern Asia. It is a tall plant with large 

 flowers and resembling a luxuriant C. rotundifolia, but is char- 

 acterized by its long spreading or reflexed calyx-lobes. To me 

 it seems to consists of two forms, one with broad oblanceolate 

 lower stem-leaves, the other with all stem-leaves narrowly linear 

 and flaccid. 



A few words may be said about the monograph in general. 

 The paper, type and printing are excellent. A full synonymy
