Cotyledons linear-oblong, obtuse, narrowed to a short petiole, 

 glabrous except the upper side of the petiole, ultimately revolute at 

 the sides, falling away early, about 1-2 cm. long including the 

 petiole, 2-5 mm. broad. 



Stem erect, terete, pale green, covered with short upwardly 

 incurving hairs ; 1st internode 1'65 cm. long ; 2nd 1-5 cm. ; 3rd 

 I'l cm. 



Leaves compound, cauline, alternate (1st and 2nd and sometimes 

 the 3rd and 4th in almost opposite pairs), exstipulate, petiolate, 

 thinly and finely pubescent above, slightly revolute at the margin, 

 deep or bright shining green above, pale and glabrous beneath ; 

 petioles convex on the back, with a 

 slender channel on each side of the 

 prominent midrib on the upper face, 

 pubescent with upwardly incurving 

 hairs. 



Nos. 1 and 2. Subopposite, tri- 

 partite ; lateral segments oblong- 

 lanceolate, subacute, with a large tooth 

 on the middle of the posterior side ; 

 terminal lobe cuneate-rhomboid, pin- 

 natifid. 



Nos. 3 and 4. Alternate or sub- 

 opposite, pinnate, pinnatifid ; basal 

 pair of leaflets ovate, acute, deeply 

 pinnatifid at the base and less deeply 

 so or toothed upwards ; terminal leaflet 

 triangular pinnatipartite at the base 

 and pinnatifid upwards, with the basal 

 and larger segments lobed, the rest 

 entire. 



No. 5. Pinnately five-foliolate ; basal pair of leaflets pinnatipar- 

 tite at the base and less deeply cut upwards ; middle pair ovate, 

 cuneate at the base, pinnatifid ; terminal leaflet triangular, acu- 

 minate, cuneate, and pinnatipartite at the base, becoming gradually 

 less deeply cut upwards. 



Ultimate leaves bipinnate ; leaflets ovate, acuminate, coarsely 

 and obtusely serrate, frequently lobed or segmented on the posterior 

 basal side. 



Walsura piscidia, Boxb. (fig. 239).
