This species appears to be different in size and venation from any 

 other Cretaceous Nelmribo. The distribution and general relation- 

 ships of the fossil nelumbos have been discussed by Berry .^ I name 

 this species for A. Allen Weymouth.

HAMAMELIDACEAE 

 LIQUIDAMBAR FONTANELLA, new species 



Figure 2 ; Plate 2, Figure 3 



The fragments of leaves in this collection would lead one to infer 

 that all the leaves of this species were deeply and narrowly 3-lobed. 

 The range of variation in modern liquidambars includes 3- to 7-lobed

leaves with the 5-lobed leaf the usual and most common form. The 

 over-all breadth of this leaf from tip to tip of the lower lobes is 13 cm 

 and the length from the top of the petiole to the tip of the middle 

 lobe is 8 cm. The lobes are 1 cm wide near the base and become 

 narrowly attenuate to their tips. The margins are finely crenate- 

 serrate. The base is slightly cordate. Length of petiole unknown. 



The primary venation includes three strong veins arising from the 

 top of the petiole, the laterals diverging at an angle of 60° from the 

 middle vein. Eight to ten pairs of secondaries appropriately spaced 

 branch off from the primaries at approximately 60°, loop upward 

 near the margin, and connect with the secondaries above. In general 

 the characters of this leaf compare Avell with those of the modern
