Trees, shrubs, often climbing, or herbs. L. opposite, undivided, generally 

 connected by interpetiolar stipules or by a raised line. Fl. regular, usually 

 bisexual, 4- or B-merous, inflorescence usually cymose. Corolla hypogynous, 

 stamens inserted on the corolla-tube, alternating with its lobes. Ovary free, 

 2-celled, ovules one or more in each cell. Embryo straight, in copious 

 albumen. 



In regard to the anatomical structure two groups may be distinguished. Buddleia 

 and allied (not Indian! genera have collateral vascular bundles. and the structure of 

 the wood is normal. The oilier genera have bicollateral bundles and consequently 

 phloern is found on the outside of the pitl and (in most species of Strychnoa) in the 

 wood, on a transverse section as islands of softer texture. See Scott and Brenner,
