in the two series seem as readily separable as are C. glabra and C. 
obliqua, in the absence of any other characters the broad-leaved 
northern plant seems best treated as a geographical variety. This 
tendency to a development of large upper leaves and foliaceous bracts 
in C. glabra is paralleled in the same geographic area by several other 
cases; for example, Eupatorium purpureum, var. foliosum Fernald 
and Solidago rugosa, var. villosa (Pursh) Fernald. 
The broad-leaved extreme of Chelone glabra seems not to have been 
definitely recognized in literature, although it is probable that Hooker’s 
description in the Flora Boreali-Americana of C. glabra: “foliis ovato- 
lanceolatis" ! was based at least in part upon it, while his “var. 8 
lanceolata Nutt." was apparently the more widely distributed narrow- 
leaved plant. This interpretation of Hooker's treatment is the more 
probable from his citation of specimens:— “Haz. a. and B. Canada. 
Newfoundland, Dr. Morison. New Brunswick. Mr. Kendal.’ But 
since Nuttall’s var. lanceolata is generally identified with the southern 
C. obliqua L. it is evident that Hooker’s application of the name to 
the northern plant was through misinterpretation. 
Since the broad-leaved northern variety has not been definitely 
distinguished from C. glabra it is here proposed as:— 
C. GLABRA L., var. dilatata, var. nov., foliis oblongo-lanceolatis vel 
oblongo-ovatis, supremis fere majoribus quam mediis 6-13 cm. longis 
2.5-5 cm. latis basi rotundatis vel subcordatis. 
Leaves oblong-lanceolate or oblong-ovate; the upper ordinarily 
larger than those near the middle of the stem, 6-13 em. long, 2.5-5.5 
em. wide, their bases rounded or subcordate.— N ewfoundland, Prince
