 part usu. alt., but in the infl. -portion alt. or in pairs ; the arrangement 

 in pairs is due to the mode of branching and adnation as illustrated 

 in the figure. In Datura the branching is dichasial, and the bracts 

 are adnate to their axillary shoots up to the point at which the next

branches arise, so that a looks like the bracteole of 2, rather than its 

 bract. In Atropa the branching is cincinnal, one of the two branches 

 at a node remaining undeveloped, and the bract is again adnate to its 

 axillary branch. Of the pair of 1. thus found at any node, one is usu. 

 smaller than the other. In Solanum, &c. further complications occur 

 (see Eichler's Bliithendiag}.
