dd Stipules not persistent on the 

 leaf -bases ; shoots and buds 

 not silky white-greenish, but 

 more or less purple-brown. 



Z Young shoots pubescent, twigs 

 reddish brown to maroon- 

 greyish, glabrous; buds, es- 

 pecially the terminal one, 

 large, black and grey, 1015 

 mm. long ; the shining violet- 

 black scales covered and 

 fringed with long white silky 

 hairs; the outermost scale 

 anterior over the leaf-scar. 

 Leaf -scar crescentic, narrow, 

 with 5 leaf-trace bundles. 



Pyrus Aucuparia, Gaertn. Rowan, or Mountain Ash 

 (Figs. 114 and 115). Buds large, shining, and with a slight 

 velvety pubescence, and white cilia to the scales, chiefly 

 confined to the inner bud-scales. Terminal bud ovoid- 

 conical ; lateral ones smaller, somewhat flattened and ap- 

 pressed. Twigs rather robust, shining greyish to red- 

 brown or deep brown, with evident but not numerous 

 yellowish lenticels, passing to deep grey or slate-coloured. 

 Outer bud-scales glistening and almost black, inner velvety 

 brown. Cortex with an unpleasant odour when crushed. 

 Dwarf-shoots prominent and densely ringed. Leaf-scars 

 crescentic with 5 leaf-trace bundles, on rather prominent 

 leaf-bases. Pith small and round. 



ZZ Buds not black and grey, 

 silky, or large; but more or 

 less velvety or cottony, as are 

 the young shoots.
