Coluria. From hoXv^o?, deprived of the tail ; or, as we usually say in English, bob-tailed. Distin- 
by Mr. Brown from Geum, principally on account of the deciduous nature of the style or tail of the 
Class XIII. — POLYANDRIA. Stamkns many, hypogynous, or inserted under the 
Ovary. 
This class agrees with the last in having hermaphrodite flowers, with an indefinite number of stamens, 
which neither cohere in any part of their length, nor are distributed in distinct parcels ; but it is distinguished 
by the stamens being inserted distinctly from the floral envelopes, immediately under the ovary, into what has 
been called the receptacle by Linnseus and his followers ; torus, by Mr. Salisbury ; and thalamus, by some other 
botanists. The class consists of the greater part of several extensive natural orders, such as Ranunculacese, 
Magnoliace£e, Cistineae, &c. ; and, like the last, is replete with subjects of interest to gardeners and florists. 
The various kinds of Clematis form the most valuable portion of the hardy climbing plants of the verandah. 
The brilliant varieties of the ranunculus and anemone constitute the most attractive part of the flower garden. 
Pfeonia, well known for the richness of its coloring, and the robustness of its constitution, is the ornament of 
every cottage ; and the noble varieties of Magnolia, the pride of the North American forest, are the finest 
exotics of the shrubbery. Nympheea and Nelumbium are beautiful genera of aquatic plants. Annona, or the 
custard apple, is one of the most important of the fruit trees of tropical countries ; and the celebrated water 
vine of Sierra Leone is a species of Tetracera. Nor must Sarracenia, with its curious pitcher-like leaves ; 
Papaver, from which opium is extracted; Cimicifuga, whence is obtained the antidote to the dangerous bite of 
the rattle-snake ; Bixa, or the arnotta tree, from the fruit of which the coloring matter for the red cheese of 
England is procured ; nor Hepatica, with its modest beauties, be omitted. 
The commencement of M. DecandoUe's laborious Systema Vegetabilium has included nearly every thing 
contained in the class, and is followed in the discrimination of the species, as being the best authority which 
can be taken.
