82 THE JOURNAL OF BOTANY 
It is of interest to note that in the Solander manuscripts, 
where the diagnosis is exactly as printed in Russell’s work, Dry- 
ander subsequently erased the specific name tenax, substituting that 
of glaucus. Kunth, Enum. iii. oe ¢ oe cites it as ‘species 
dubie affinitatis.”” Buchenau, l.c 243, ge it a synonym of

a for 
laxly effuse panicle and small roundly chivede fruit (2 5 mm. ig 
perhaps referable to var. Tommasinit Buch. 1. c. 250.

Poiret’s description and notes, and his citation of Juncus acutus

In brief, then, the species stand thus :—
