2. Sparganium Linn. Bur-reed. 
Spadix spherical. Perianth of 3 — 6 scales, which are broader 
upwards (sterile stamens ?). — Barren fl. Stamens 3, distinct, 
or nearly so: anthers ovate. — Fertile fl. Pericarp without 
hairs at the base. — Name: a-apy avov, a little hand; from its 
narrow and long leaves. 
1. S. ramOsum Huds. (branched B.) ; leaves triangular at 
the base their sides concave, common flower-stalk branched, 
stigma linear, fruit sessile. E. B. t. 744. S. erectum L. 
Banks of ditches, lakes, and stagnant waters. If. 7. — Stem 2 feet 
and more high, with a few long, sword-shaped leaves or bracteas, 
having broad membranous sheathing bases on the upper or branching 
part. Root-leaves very long, linear, ensiform, triangular at the base, 
their sides concave. Lower branches of the inflorescence with several 
rather distant heads, of which 1 — 3 of the lower ones are composed of 
fertile, the others of sterile flowers. 
2. S. simplex Huds. (unbranched upright B.) ; leaves tri- 
angular at the base their sides flat, common flower-stalk nearly 
' simple, stigma linear, fruit subsessile. E. B. t. 745. S. erectum 
(3. L. 
Ditches and stagnant waters, especially in a gravelly soil. If. 7. 
— Much smaller than the last. Common flower-stalk rarely, if at all, 1 
branched, the branches or partial flower-stalks bearing only a single i 
head of fertile flowers ; the other fertile heads and all the sterile ones I 
are sessile. The sides of the leaves are plane, not concave or grooved ; I 
the flowers pale yellow. 
3. S. nutans L. ( floating B.) ; stem flaccid, leaves floating, I 
common flower-stalk simple,’ fruit with a long beak stalked, : 
heads of sterile flowers several. Fries Summ. p. 560. S.

Lakes. Island of North Uist, and Galloway, Scotland. Snowdon, > 
Wales. Connemara, Ireland. If. 3. — Of this we have seen no I 
specimens. Fries says the fruit is furnished with a long stipes, which 
seems to be formed by a contraction of its lower half. This appears fl 
principally to differ from the rest by the fruit being more attenuate II 
at both extremities. 
4. S. minimum Bauh. (small B.) ; stem flaccid, leaves float- ' I 
ing plane, common flower-stalk simple, stigma oblong, fruit with 
a short beak sessile, head of sterile flowers solitary. S. natans
