 sarmentose branches, rarely climbing, glabrous: Ivs. 

 short-petioled or almost sessile, the upper connate, oval

47. implexa, Ait. Much-branched, but less high- 

 climbing, evergreen: Ivs. oval to oblong-lanceolate, ses- 

 sile, the upper connate into an elliptic, acute or mu- 

 cronate disk, glaucous, glabrous 1-2 in. long: fls. in sev-

 short; stamens slightly exceeding the mouth. May, 

 June. S. Eu v N. Afr. B.M. 640.

 Climbing: Ivs. oval to oblong, the upper connate into a 

 roundish cup, al- 

 most glabrous, 2-4 



in. long : whorls 

 usually 2 or 3, 

 each in the axils of 

 connate Ivs. : fls. 

 yellowish white, 

 often slightly pur- 

 plish outside and 

 slightly hairy, to 2 

 in. long, fragrant; 

 bractlets very 

 small or none.

49. am eric ana,

 obovate, the upper connate, glabrous, 2-4 in. long; the 

 upper whorls without connate Ivs. at the base, some- 

 what crowded: fls. yellowish, usually purple outside and 

 glabrous, fragrant, to 2 in. long; bractlets about half as 

 long as ovary, smaller on the upper fls. June-Aug. 

 Probably hybrid of L. etrusca and L. Caprifolium, much 

 cult., mostly under the name of the latter, and some- 

 times escaped from cult. Gn. 45, p. 307 (as L. etrusca

 2 in. long: fls. in peduncled spikes with few somewhat 

 remote whorls, purple outside and sparingly glandular, 

 lJ4~2in. long; bractlets about half as long as ovary.
