CLEMATI'DE^E (plants resembling Clematis,) D. C. syst. 1. 

 p. 131. prod. 1. p. 2. Calyx when in bud valvate (f. 2. I.e.) 

 or induplicate (f. 4. d. c.). Petals none (f. 3. and 4.). or 

 flat (f. 5.). Anthers linear, turned outwards (f. 4. &.). Carpels 

 aggregate (f. 3. 6.), l-seeded, indehiscent, terminated by a tail, 

 (f. 3.c.). Seed pendulous (f. 3. d.). Leaves opposite (f. 3. and 4.). 

 Roots fibrous. 



I. CLE'MATIS (from icX/jua, clema, a vine branch, because 

 most of the species climb like the vine) Lin. gen. no. 695. Gaert. 

 fruct. 1. p. 353. t. 14. D. C. syst. 1. p. 131. prod. 1. p. 2. 



LIN. SYST. Polydndria, Polygy'nia. Involucre none, or situated 

 under the flower, in the form of a calyx. Calyx of from 4 to 8 

 coloured sepals. Petals none (f. 3. and 4.). Carpels numerous, 

 aggregate (f. 3. b.~), terminated by a long, mostly feathery, tail, 

 (f. 3. c.). Climbing ' shrubs, with variously cut opposite leaves, 

 (f. 3. and 4.) The recent herb of all the species is more or 

 less acrid, and when applied to the skin occasions blisters. 



The English name of this genus, Virgin's-Bower, is given to 

 it on account of several of the species being used for covering 

 bowers. It is also called Traveller's-joy, because several of 

 the species grow in hedges by way-sides, as well as from the 

 beauty and the scent of their flowers, or more probably from their 

 affording a grateful shade. 



SECT. I. FIA'MMULA (from Jlammeo, to inflame ; blistering 

 qualities of plants). D. C. syst. 1. p. 131. prod. 1. p. 2. Invo- 

 lucre wanting. Tail of carpel long, bearded, feathery (f. 3. c.). 

 Cotyledons distant in the seed. 



1. Florvers panicled. Leaves pinnate (f. 4.), or bipin-
