4 ENGLISH BOTANY. 
SPECIES I1L—-TYPHA ANGUSTIFOLIA. Linn.

Reich. Ic, Fl. Germ. et Helv. Vol. [X. Tab. CCCXX. Fig. 744.1 
Billot, F). Gall. et Germ. Exsice. No. 2943. 
Leaves narrowly linear, nearly flat on the inside, slightly convex on 
the back, not glaucous. Male and female spikes separated by an 
interval of naked rachis; the former without subfoliaceous bracts. 
Female spike elongate-cylindrical, rusty colour in fruit: stigma linear- 
subulate; hairs of the axis slightly thickened towards the apex, so 
as to be somewhat scalelike. 
In ditches and pools. Not unfrequent in England, and widely dis- 
tributed. Very rare in Scotland, where it is said to grow in Loch 
Maben, Dumfries, Colvend Manse Loch, Kirkeudbright, and Lindores 
Loch, Fife. Rare in Ireland, and confined to Dublin and Antrim. 
England, Scotland, Ireland. Perennial. Summer. 
Very similar to T. latifolia, but readily distinguishable by its 
narrower leaves (+ to 2 inch long), which are more convex on the 
back, and deep green, not glaucous. ‘The spikes are always s separated 
by about an inch, and occasionally the female spike is divided into 
2 portions; it is usually longer ‘and considerably thinner than in 
T. latifolia, not exce eding 3 inch in breadth even in fruit, when it is 
of a bright rusty brown. The broader stigmas and hairs give a more 
scaly aspect to the spike than in T. latifolia. 
Smith mentions that in the marshes of Great Oakley, Essex, the 
Rey. Revett Sheppard found what seems a variety of T. angustifolia, 
with much thicker fertile spikes than usual; and as it was growing 
with T. latifolia, Mr. Sheppard thought it might be a hybrid between 
the two. 
Narrow-leaved Cat's Tail. 
Vrench, Massette d feuilles étroites. German, Schmalblittriges Kolbenrohr, 
Schnale Rohrkolbe. 
GENUS II—SPARGANIUM. [Tournef. 
Flowers monecious; the male and female in several separate globular 
heads, one above the other in a spike, raceme, or panicle separated 
distinctly; the male flowers towards the apex of the stem, and 
also of the branches, when the flowers are paniculate; the separate 
heads, or at least the female ones, with large foliaceous persistent 
bracts. Male flowers very numerous: perianth none (?): stamens 3 ; 
filaments distinct or nearly so, surrounded by 3 to 6 scales dilated at
