contracted from the top of the sheath ; channelled, hollow, with 

 distant, transverse partitions, and likewise with a longitudinal par- 

 tition from back to front (hence the leaf appears to be doubly 

 tubular). Flowers from two to five, on each stem : capsules taper- 

 ing at the summit. 



Juncus trijidus. Rocks to the east of the summit of Mael Ghyrdy : 

 not observed any where else in that district. July.

 the south-west, very sparingly. August. 



G. campestris : a white variety, very abundant in many situations near 

 Killin.

 It prefers barren, somewhat moist declivities, where the soil barely 

 covers the rock. July. 



The stamens, as well as the pistills, vary greatly in number. More 

 than ten of each are often found on the same flower. I cannot see 

 how it differs from Potentilla. Herbage decidedly glaucous, but 

 with a blackish tinge.

 Lister a cor data. July.

 places : a very doubtful species. June.
