of which spring seven leaf -bearing branches or branchlets 

 in a regular yerticillate or candelabra-like arrangement, 

 upon which we look vertically, either from above, or, 

 more probably, from below. 



Perhaps nothing is shown more conclusively in this 

 specimen than the very variable manner in which the 

 gradual lengthening of the internodes from the base up- 

 wards takes place in different branches, even belonging 

 to the same whorl. Clearly specific characters based 

 upon this point alone (as they have more than once been 

 based) must be of very small value. In the present case 

 two species of this kind could obviously be claimed 

 growing on the same stem. 



At the point of junction between the branches and the 

 stem a more or less confused mass of carbonized matter, 

 rather better shown in the fossil than in the Plate, re- 

 presents the outer bark and sub-jacent vascular zone 

 uniting the members to the parent trunk. 



The Plate is slightly reduced from the original drawing 

 by Mr. T. Johnson, which is itself about half the size of 

 the specimen.
