1889. The specimens although scanty show the paroicous inflores- 

 cence characteristic of the species and are infested with the peculiar 

 fungous growth which seems to be almost invariably present. 

 The plant has also been reported from Greenland, California and 

 Alaska, but these are apparently the only North American stations 

 that have been recorded. Scapania carta and Anthetia Juratxkana 

 have recently been described by Howe, 1 who also points out the 

 differences between the latter species and A. julacea (L.) Dumort., a 

 plant which may likewise be expected in the White Mountains. 



14. Radula obconica Sulliv. The range of this species as given 

 in the Manual is from New Jersey to Ohio. It has been collected 

 by the writer at Hamden, Connecticut.

VARIATIONS OF GLAUX IN AMERICA. 

 M. L. Fernald. 



Those who are familiar with our sea-side flora have doubtless 

 many times come across the blue-green patches of Glaux occupying 

 areas of salt-marsh near high-water mark. At any time in summer 

 or fall the plant attracts attention, and if it is found in June or early 

 July it immediately claims our interest by the delicate flowers in the 

 upper leaf-axils. Although the plant belongs to the natural order 

 Primulaceae it has no corolla, but instead the calyx is much devel- 

 oped and beautifully colored, either white, rose-pink, or crimson, 

 with more deeply hued centre. 



The plant familiar to most botanists whose sea-shore collecting 

 has been only in New England is simple or with a few erect branches, 

 and it has oval or broadly elliptic-oblong leaves generally a centi- 

 meter long and rounded at the tip. This erect plant is common in 

 salt-marshes and on muddy sea-shores from the Gulf of St. Lawrence 

 to Nantucket — and it is said to extend even to New Jersey. It 

 was, therefore, of no special interest, in early July last, to find the 

 common erect plant growing below tide-limit on a muddy shore at 

 Cutler,, Maine.
