 alternate at greater or less distances from each other, or in 

 pairs, or all four verticillate, ovate, obtuse, emarginate, articulated 

 at the top of their petioles, or the lowest pair articulate at the base 

 only. 



Nos. 3 and 4. Frequently digitately trifoliolate, the terminal 

 leaflet being lanceolate-elliptic, attenuate at the base ; the lateral 

 leaflets arise by segmentation from the terminal one. 



No. 4. In some instances five-foliolate ; the rachis between the 

 basal and next pair of leaflets winged and tapering towards the base 

 in the same way as the primary petiole ; leaflets sessile, lanceolate- 

 elliptic, emarginate, minutely and doubly crenulate, smaller than 

 the leaflets of unifoliolate leaves.

 resin or oil glands ; petiole deeply channelled above, 4 mm. long. 



No. 3. Pinnately trifoliolate ; lateral leaflets rotund-elliptic ; ter- 

 minal one elliptic ; all obtuse, coriaceous ; petiole flattened above, 

 pubescent, subverrucose ; rachis between leaflets similar to petiole 

 and articulated with the leaflets. 



No. 4. Similar to No. 3, but much smaller. 



No. 5. Imparipinnate ; leaflets four, alternate, irregular in size 

 and shape, oblong or lanceolate, obtuse, entire the terminal one 

 much the largest. 



No. G. Imparipinnate ; leaflets four, irregular oval, oblong, or 

 subelliptic, obtuse. 



Ultimate leaves three- to five-foliolate ; leaflets alternate, ovate,
