meadow at Berkshire, Vermont, and later determined by Professor Ames as a peloric form of 

 Habenaria psycodes which was described, figured, and named var. ecalcarata by Miss M. M. 

 Bryan in the Ann. Missouri Bot. Gard. 4: 38. 1917. The peculiarities of this form "(for 

 it seems to be a teratological development rather than a true variety)", are an oblong-ovate, 

 spurless petal in place of the usual three-parted, spurred and fringed lip; and the develop- 

 ment of four anther sacs set at various angles in a rough semi-circle about its upper part, 

 instead of the usual two nearly erect anther sacs. All of the flowers of the inflorescence 

 wer(! alike. — James P. Poole. 



1496. WiEGAND, K. M. Variations in Lactuca canadensis. Rhodora 22:9-11. 1920. — 

 The writer has attempted a classification of the varieties and forms of Lactuca canadensis 

 which seems to accord more with the material found in the field than does the treatment found 

 in our various manuals. In floral and fruit characters L. canadensis is remarkably con- 

 stant, and it is only in the leaves that great fluctuation is found. A short discussion of some 

 of these variations is given, with a summary in the form of a key. Descriptions and bibli- 

 ographies of the species and the forms recognized by the writer are given. — James P. Poole. 



1497. WiEGAND, K. M. A new species of Spergularia. Rhodora 22: 15-16. 1920.— An 

 account of the discovery of an apparent new species of Spergularia, which the author pro- 

 poses as S. alata sp. nov. This species was collected at different times from 1916 to 1919 by 

 different collectors, from the brackish soil about salt springs and salt ponds in central New 

 York. A description is given as well as a comparison with the more closely related species. 

 The attention of botanists is called to the plant in the hope that it may be found elsewhere. — 

 James P. Poole.

 Rupprechtii f. viridis are described as new and a full description of Thuja koraiensis Nakai 

 given. — Alfred Rehder.
