This is about three inches in height, and it spreads out 

 greatly: it is fully more in breadth. The branches are 

 much compressed, and truncate at the extremities, bearing 

 a considerable resemblance to the antler of a stag. It differs 

 considerably from C. ramulosa, in being a stouter fabric,

 spreading. It is rarer than C. ramulosa. It has often a 

 varnished appearance.
