network of slender veins, but distinguished by its narrow lanceolate 

 outline. The other two species are more similar to ours in 

 outline and size of leaf ; but C. undulatum is distinguished from 

 ours by bigger teeth of the undulate margin, and C. granclifollum 

 by showing a coarse quadrangular reticulation of tertiary veins 

 between the laterals. Converging with some species of Celastro- 

 phyllum in several features, our specimen possesses an essential 

 difference to warrant the estabhshment of a new species. But the 

 real generic position of it and of all allied types is still a broad 

 question, because, for instance, a quite similar leaf was described 

 as Tenistroemia crassipes Vel. by Velenovsky^', mentioning the close 

 resemblance of it with Camellia japonica (tsubaki), and still more 

 with Ternstroemla dentata Sw. (the same family) from Guyana. 

 For lack of sufficient specimens of our type, I must limit myself 

 to the above comparison. I must also mention here, that some 

 impressions, described as Myrica, have several features in common 

 with ours and with those described as CclastropJiyllum.

Leaves broadly cordate or orbicular, attaining 8 cm. in length 

 and 8 cm. in width in broadest part. Base of the leaf slightly 

 cordate, sinus broadly open, lamina a httle decurrent. The limb 

 palmately trilobate, without any subordinate lobes. Median lobe 

 elliptic, with pointed top and sometimes strictly contracted at the 

 base. The lateral lobes are separated from the median by sinuses 

 with rounded bottom, and are curved outward. Primary nerves 

 three, diverging radially, from one point at the base of leaf, 

 running directly into the summit of each lobe. From each of the
