 Surface of the stem marked by scars, 

 points of leaf attachments; leaf scars 

 (bolsters) rhomboidal, oblong, upon the 

 bark of large trees or small branches, 

 variable in size according to their posi- 

 tion, often disfigured; central cicatrices 

 (inside scars) rhomboidal, transversely 

 dotted by three points (vascular scars) 

 bearing, generally, under the lower mar- 

 gin two oval small tubercles, scars of 

 bundles of vessels (appendages) placed 

 on each side of a medial line (cauda), 

 which, like the appendages, is more or 

 less distinct, sometimes deep and 

 wrinkled across, sometimes obsolete. 

 Type L. dichotomum.
