time of Mutthiolus to the recent introductions from the Himalaya. The acrid 

 properties of the C'lematis are well known to herbalists. The bark, leaves, 

 and blossoms are used to raise blisters on the skin, or to produce a slight ex- 

 ternal inflammation : taken internally they are a corrosive poison. The flow- 

 ers contain a peculiar substance, called clematine, which is similar to gluten ; 

 the green leaves, bruised, are applied to ulcers, to produce sloughing. The 

 floricultnral use of these plants is, to cover bowers, or ornament verandas or 

 trellis-work. The greater number of them ripen their seeds in England, and are 

 easily propagated by them, or by layers. They all require support by props of 

 some kind ; and all grow freely in any soil that is tolerably dry, but more es- 

 pecially in one that is calcareous. From the acridity of these plants, they are 

 not very liable to be attacked by insects ; nevertheless, snails and slugs are oc- 

 casionally found eating their young herbage. Most of the species and varieties 

 which we shall describe are to be found in the principal botanic gardens of 

 Europe, and have been seen by us in that of the Horticultural Society of 

 London ; and the more ornamental of them are cultivated for sale in the prin- 

 cipal European and American nurseries. 



The ligneous species of C'lematis are included in four sections; viz. Flam- 

 mula, Viticella, Cheiropsis, and /Jnemoneflora.

Varieties and their Sfynonymcto The following are given by De Candolle ; 

 but they are not of much importance in point of general effect. 



-A C. F.2 rotundifolia Dec., fragrans Tenore. Leaflets almost orbicular. 



.1 C. F. 3 maritima Dec. Leaflets linear. 



1 C. F. 4 rubella Dec. Leaflets oval, usually emarginate. Sepals 



four, reddish on the outside. 



.A C. F. 5 ccsspitosa Dec., C. ccEspitosa Scop., C. Fldmmula Bertol. 

 Leaflets minute, entire, or cut. 



Desc>-i])tion. A vigorous-growing plant, the stems of which attain the 

 length of 10ft. or 15ft. in a wild state, and from 15ft. to 30ft. in a state of 

 culture. The leaves of the entire plant are subject to much variation, from 

 .soil, situation, and climate. The shoots of a well-established plant, which 

 has been cut down, grow with great rapidity in the early part of the season, 

 attaching themselves to whatever is near them. The peduncles of the flowers 

 are sometimes simple and sometimes branched. The colour of the sepals is 

 white, slightly pubescent on their exterior margins. The whole plant has a 

 dark green hue ; and in autumn it is abundantly covered with flowers, the 

 odour of which is of a honeyed sweetness, exceedingly disagreeable to some 

 persons when near, though at a distance it is not unlike the fragrance of the 

 common hawthorn. The number of the styles varies from five to eight, each
