rimis laevibusque, saepius profunde lobatia vel trisectis, segmentia obtusis terminali 

 acuto; cirrhis bifidis; pedunculis communis masculis vix ramosis, foliis plerumque 

 longioribus, floribus parvis, superne in fasciculos paucifloris subverticillatim ramulosos; 

 calycis dentibus setaceis plus minus ve longis; fructu breviter pedunculato, dense 

 echinato, apice longe acuminato. — Cogniaux, loc. cit., emend. 



Stems slender, angulose, little branched, smooth. 



Leaves variable in size, texture, and subdivision of the lobes. Petioles 3 to 10 cm. 

 long, slender, striate. Leaf blades 4 to 12 cm. long, 5 to 14 cm. broad, more or less 

 punctate, light green above, paler beneath. Leaflets shortly petiolate, denticulate or 

 subcrenate, the tips and teeth mucronate, the three middle leaflets more or less pin- 

 nate, the exterior ones almost always distinctly trilobate-auriculate. Tendrils bifid, 

 rather slender and elongate.
