originating from former impregnation. The fertile catkins of 

 T. angustifolia sometimes split longitudinally in growing. See 

 Engl. Bot. 



3. T. minor. Dwarf Cat's-tail or Reed-mace. 



Leaves linear, convex beneath. Catkins a little distant ; 

 barren one leafy ; fertile short and turgid ; often inter- 

 rupted. Anthers nearly solitary. Receptacle naked.

Perennial. July. 



Much smaller than either of the preceding. Stem very slender, 

 about a foot, or foot and half, high. Leaves about a line in 

 breadth ; channelled above ; convex beneath ; as tall as the 

 stem ; pale and blunt at the point, being rather more tumid in 

 that part than the other species. They are accompanied by nu- 

 merous broad sheathing scales, the innermost of which are half 

 as tall as the stems, and have been taken for leaves. Willdenow 

 not having seen a remark to this effect in Engl. Bot. has been 

 led to make two species out of one. The barren catkin often 

 bears a membranous leaf, or scale, at the base, or at the sum- 

 mit. The anthers are short and thick, mostly solitary on each 

 /lament. Recept. apparently naked. Fert. catkin short and 

 thick, becoming tumid, and oval, as it ripens, frequently inter- 

 rupted about the middle ; its upper half is sometimes conti- 

 nuous with the barren catkin. Seed with numerous bristles at 

 the base of its stalk, I have seen no English specimen of this 

 very distinct species ; but the older writers could not possibly 

 mistake it, nor would Linnaeus, had he ever examined the plants, 

 have confounded it with the last.
