igo ANNALS OF SCOTTISH NATURAL HISTORY 



I have had occasion to note the likeness in habit, etc., 

 of some pulla forms to limosa, and vice versa. 



One of Mr. Duncan's specimens has the lower spike 

 springing from the leaves of the rootstock, thus having a 

 leaf forming the bract. I have seen this in Jiirta, glauca, 

 panicea, etc., but not in the liinosa series before. 



Although I admit that it differs so much in look from 

 the typical form, I do not see that it is possible to call Dr. 

 Shoolbred's specimen a variety, as in the North Harris ex- 

 amples the glumes pass from his form, through all the forms 

 given above, to exactly the glume figured under Fries's 

 stygia. 



Another critical Hebridean Car ex found by Mr. Duncan 

 was referred by me doubtfully to a salina form, " being very 

 near C. spicttlosa, Fries." I see that Dr. Hjelt x refers Fries's 

 plant to " C. salina x vulgaris,juncella? Dr. Almquist agreed 

 that the plant was very near spiculosa, Fr. ; and vnlgaris jun- 

 cella certainly occurs in the group, but no salina has yet 

 been found, though Mr. Duncan has been over the ground 

 again. C. spiailosa is very rare in Finland, being found only 

 on the Kunookotka promontory in the White Sea. Though 

 not absolutely identical with Fries's plant, ours is very 

 near it. 



Hjelt has a C. aqitatilis x vulgaris,juncella, which he says 

 (t. Almquist, I presume) is C. amiata of Laestadius : " Bidrag. 

 Kan. i Tomea Lappmark," p. 43 (1860). This I have not 

 seen, but I do not see that one can say juncella positively 

 enters into the Hebridean plant. Laestadius compares his 

 plant with aquatilis and acuta, and says that it grew with 

 Betula nana, V actinium uliginosum, Tofieldia borealis, Pingni- 



cula villosa, etc.
