276 DR. P. GROOM ON THE LONGITUDINAL 
On Branch 2, the branch subtended by the seventh leaf was “ fused " with the parent- 
axis for a considerable distance upwards ; a ridge and two furrows clearly marked the 
outline of the * fused " part of the branch. The branch subtended by the ninth leaf was 
likewise displaced upwards, though in this case there was no such clear projecting ridge 
denoting the “fused” part of the branch; still, the supra-axillary position of this, 
the lack of any subtending leaf immediately beneath it, and the lack of any bud in the axil 
of the truly subtending leaf were sufficient evidence of the “ fusion.” The branch truly 
subtended by the tenth leaf was likewise raised (for a distance of 3°5 millimetres) in 
insertion above the leaf; it was a short sessile fruiting branch. Above this, all the 
branches were more or less supra-axillary, but there was no suppression of leaves on the 
relatively main axis (the apparent suppression being due to branch-displacement). 
On Accessory Branch V similar “fusions” and displacements occurred, the lowest 
being that truly subtended by the fifth leaf.
