Perennial. — Flowers in July and August. 
An aquatic plant, floating under water. Stem round, smooth, 
branching, deep green. Leaves finely pinnatifid, smooth, spread- 
ing, 4 or 5 in each whorl ; those on the flowering part of the stem 
or branches, which rises 5 or 6 inches above the water, less deeply 
cut. Flowers small, in whorls, in the axils of the emersed leaves ; 
the upper ones with stamens only ; the lowermost less numerous, 
with pistils only ; intermediate ones often with both. Petals green- 
ish. Anthers yellow. 
Another species of this genus, Myriophyllum alterniflorum of Decandollb, 
has been lately added to the British Flora by the Rev. Andrew Beoxam, M. A. 
of Worcester College, Oxford. This gentleman discovered it first about four years 
ago, at Whixal Moss, Salop ; and again on the 20th of June, 1839, in abundance, in 
a pond near his own residence at Twycros9. Leicestershire.— Mr. C. C. Babington 
found it in Guernsey in 1838. Mr. Bloxam has kindly favoured me with speci- 
mens of it, from Twycross. 
The Natural Order, Haloragea:, is composed of polypetalous, 
dicotyledonous herbs or under shrubs, the greater part of which 
are inhabitants of water and moist places. Their leaves are oppo- 
site, alternate, or in whorls. Their flowers axillary, sessile, or in 
terminal spikes, occasionally monoecious or dioecious. The calyx 
tube is adherent to the ovary ; and its limb is minute, 4-parted, 
or almost wanting. The petals are minute, and are inserted into 
the mouth of the calyx, or wanting. The stamens also arise from 
the mouth of the calyx, and are either equal in number to its lobes, 
or double as many, rarely fewer. The ovary adheres inseparably 
to the calyx, and has one or more cells. The stigmas are sessile, 
and equal in number to the cells of the ovary. The fruit is dry, 
and indehiscent ; of one or more cells. The seed is solitary, and 
pendulous ; with fleshy albumen ; a straight embryo ; a superior 
radicle; and minute cotyledons. — The plants contained in this 
order are not known to posses any medical properties. The only 
British genera are Hippuris, t. 49 ; Myriophyllum, t. 376 ; and 
Callitriche.
