Foliage entirely under water, as in Myriophyllum. Spike of the flowers 
alone rising above, (in a lofty pyramidal form. E.) Some Jlowers have 
six stamens, when the cup and the blossom are divided into six segments. 
( Leaves crowded, three or four inches long,, bright green, deeply pinna- 
tifid. E.) Whether we consider the lightness of its elegantly winged 
leaves, or its whorled spikes of lilac-coloured blossoms, it is certainly 
superior in beauty to most of our indigenous plants. 
(Mr. Hanbury has observed a beautiful variety with rose-coloured blos¬ 
soms. FI. Brit, and in Bot. Guide a similar discovery is announced by 
Mr. Rudge, near Kelmarsh, Northamptonshire. E.)

* This beautiful plant is worthy of being introduced with Nymphaa, Nuphar, Hottoma y 
&c. in the ornamental aquarium, destined for the reception of Chinese (gold and silver) 
ps; and merits the eulogium of the poet, 
“ Oft where the stream meandering glides, 
Our beauteous Meny ant lies hides 
Her clustering, fringed flowers; 
Nor mid the garden’s sheltering care, 
Of fam’d exotics rich and rare, 
Purple or roseate, brown or fair, 
A plant more lovely towers.” S. H. E.) 
An infusion of the leaves is extremely bitter and sudorific. It is prescribed in rheumatisms 
and dropsies. A dram of them in powder proves drastic and emetic. It is occasionally 
given to destroy worms. In a scarcity of hops this plant is used in the north of Europe-to 
bitter the ale : two ounces are equal to a pound of hops. The dried leaves are sometimes 
smoked. The powdered roots have been used in Lapland as a substitute for bread, but they 
arc unpalatable. (Of the various miserable expedients for supporting life in the desolate- 
regions of the north, this surely must be one of the most disagreeable, and can only be 
reconciled by the old adage, 
‘‘Quodque aliis cibus est, aliis fuit acre venenum.” E.) 
It has been said that it cures sheep of the rot; but from the Upsal experiments it appears 
that, though goats eat it, sheep seldom dp. Cows, horses, and swine refuse it. (Dr. Lewis 
considers it an efficacious aperient and deobstruent. It has gained reputation in scorbutic 
disorders, a pint a day of infusion of the leaves removing inveterate cutaneous eruptions. E.)
