The right axillary distribution, which has briefly been sketched, differs greatly from the left in the horizontal direction of its trunk and of most of its divisions, and in the more limited share which it takes in the formation of the apex proper. Shortened internodia and, as a result, apparent trifurca- tions are frequent in this distribution which thus rapidly acquires an extensive periphery.](https://iiif.wellcomecollection.org/image/b21518701_0148.jp2/full/800%2C/0/default.jpg)
