 " J. brevirostris, Nees, Comp. Fl. Germ. ed. i. p. 881." (Test. Koch.) 



Flowers in fascicles of 6 to 12. Perianth leaves dark brown, as

Var, (3 apparently I'ar'e. Kingcausie, Kincardineshire. 



England, Scotland, Ireland. Perennial. Summer, Autumn. 



Stems 1 to 2 feet high or more, but never so tall as in J. obtusi- 

 florus, from which it differs also in the stems and leaves being 

 slightly compressed, the stem leaves usually 3 and shorter, the panicle 

 less compound and \vith shorter branches, the longest branches rarely 

 more than 2 or 3 inches, and its ultimate branches not spreading at 

 right angles. Per.anth leaves nearly ^ inch long, very acute, usually 

 brown, especially when in fruit. Capsule narrower, more gradually 

 acuminated and darker coloured than in J. obtusiflorus, and so gradu- 

 ally acuminated that it is beaked rather than mucronate. Seeds similar 

 to those of J. obtusiflorus, but a little longer.

SubcsBspitose. Rootstock shortly creeping, its branches producing 

 stems close together. Stems ascending, slightly compressed, smooth 

 when fresh, faintly striate when dry, solid at the base, hollow with 

 distinct dissepiments above. Radical sheaths pale, all except the 

 lowest with an elongate lamina like that of the stem leaves. Stem 

 leaves 2 to 4, sheathing, their lamina terete and more or less com- 

 pressed, hollow with numerous partitions, which give the dried leaf 

 the appearance of being jointed, all of them much shorter than the
