BURSERACEAE. 



Canarium sp. 



Habitat Sikkim. 



Coll. December 1897. 



The peculiarity of the leaf represented in fig. 42 consists in 

 its common petiole having been split up and in the two parts 

 having lengthened differently. As high as the base of the ter- 

 minal leaflet the fissure becomes apparent, the base itself being 

 torn up and oblique. The leaflets of the preceding pair are 

 fairly opposite, but those of the second pair occupy different 

 heights. Of the lowest pair only the right one has grown out, 

 whereas the left one is a mere little knob. The latter is placed 

 in the groove which downwards prolongs the fissure and only 

 close to the base of the common petiole disappears. Most pro- 

 bably the splitting up of the common petiole has through an 

 unknown cause arisen at the base of the terminal leaflet when 

 still verj^ young and from thence proceeded downwards.
