Exotic weeds, nearly related to Rubiacea?. Their properties are unknown. M. de Jussieu has remarked 

 that their affinity to Valerianea? is supported by the curious circumstance, that birds devour the young shoots 

 of the Opercularias as they do those of the corn-salads. Seeds or cuttings.

Small herbaceous plants, more interesting for the sake of their symmetry and neatness, than on account of 

 any particular attractions : they may be considered a connecting link between Rubiaceae and Dipsacese. 

 Many of the Valerians, and all the Patrinias, are pretty plants. The Valerianellas are useful esculents, 

 known under the name of corn-salads. Their medicinal properties are of a decisive character. The roots 

 of Valeriana officinalis, Phil, and others, are bitter, tonic, aromatic, antispasmodic, and vermifugal ; they 

 are occasionally used as febrifuges. The odor of Valerian is not generally agreeable, but the Orientals 

 collect with care, on the mountains of Austria, the roots of Valeriana celtica, with which they perfume their 

 baths ; and the natives of India, at this day, employ the Valeriana jatamdnsi, the spikenard of old times, as a 

 perfume, and against hysterics and epilepsy. Division or seeds. »

Very nearly akin to Comp6sita=, of which they have nearly the habit. All are herbaceous plants with 

 flowers growing in heads. Some of the Scabiosas and Asterocephalus are very handsome, and popular border 

 flowers. The whole tribe is cultivated with great facility. Some of the species of Scabibsa have been employed 

 as diaphoretic and antisyphilitic, but are now neglected. Division or seeds.

A most extensive and natural order, obviously characterised by the cohesion of their antherse, and the 

 arrangement of their florets in involucrated heads, or calathidia, as they are now called. Most of them may 

 be said to be ornamental plants, and yet but a very few hold that station in the opinion of the public. It is 

 difficult to account for this circumstance, nor is this the place to enter upon such an investigation ; certain, 

 however, it is, that with the exception of georginas, the varieties of Chrysanthemum sin^nse, and a few Calen- 

 dulas and Arctotises, and perhaps Tagltes, scarcely a single Composita now finds a place in a fashionable 

 flower-garden. The prevailing colour of the flower in the order is yellow; red, purple, or scarlet being com- 

 paratively uncommon. The species inhabit every part of the world, and in all, perhaps, in nearly equal 

 proportions : in Europe and the north of the world they are chiefly herbaceous ; but within the tropics, they 

 are more frequently frutescent. Their medical properties are very important: Tussilago Parfara, Chamomile, 

 /'nula, Solklago, Virgaurea, Matricaria, Parthenium, Stev?'a febrifuga, and Eupatbrium perfoliatum are 

 instances of the presence of tonic and febrifugal properties; Tanacetum and Santollna are anthelmintic; 

 Matricaria and the Achilleas emmenagogue; some Eupatoriums, Achilleas, Artemisias, and Calendulas are 

 sudorific ; certain Liatrises are diuretic, and iJrigeron philadelphicum is both sudorific and diuretic. 

 Ptirmica and A'rnica are sternutatory, and Spilanthes, Siegesb£ck«« orientalis, J'nthemis Pyrethrum, and 

 others, powerfully excite salivation ; finally, many Achilleas, Chamomile, Tanacetum, and Eupatoriums are 

 tonic and antispasmodic. Others seem to possess all these properties combined, and are reckoned among the 

 best alexiterics, as the Ayapana of Brazil, and the Guaco of Peru. Every one knows the excellent and 

 refreshing flavour communicated to vinegar by Tarragon : the same effects are produced in the Alps by 

 Achttlha nana,,4rtemis^a glacialis, rup^stris, and spicata. Some species of Jchille«, Pedis, and Artemisia have 

 keen used as substitutes lor tea. The seeds of many Composita?, as Madia and Verbeslna, yield a copious oil ;
