CiSSIlES DENTATO-LOBATUS, Sp. DOV. 



PI. LXVI, Fig. 4. 



Leaf cordate in outline, enlarged in the lower part, irreg-ularly dentate- 

 lobate, trilobate above the middle, the lobes irregular, enlarged above, 

 ol)tusely dentate or ii-regularl y lobed toward the apex ; median lobe pro- 

 longed upward; narrowed in. the middle toward the obtuse sinuses. 



This leaf is very peculiar in its multiple division. It is 9"'" long, S"" 

 broad near the base, trilobate from the middle, the two lateral lobes broader, 

 one of them partly dentate and lobed, the other four or five deeply, obtusely 

 lobed, the middle naiTower and enlarged above, and these irregularly divided 

 into five obtuse, short lobes, one only obliquely prolonged. The peculiar 

 form of the leaf can not be understood without figures. It has a distant 

 affinity to the fragment described as Cissua vitifolia Velen. (Flora bohm. 

 Kreidefl., pt. 3, p. 8, PI. ii, Fig. 6).
