70 Addisonia 



The species here illustrated seems not to have been observed 

 until 1903. It has a stout, frequently knob-like root, which is 

 often seated in or nearly enclosed in a cavity of the honeycombed 

 limestone on which the plant grows. From this root dozens of 

 stems spring and spread radially on the ground. Single plants thus 

 form mats on the rocky pineland floor, varying from two to six 

 feet in diameter. When covered with myriads of golden-yellow 

 flowers, as they are nearly if not quite throughout the year, these 

 mats form the most conspicuous floral element of the woods. On 

 account of the showy flowers this plant is sometimes grown in 

 neighboring gardens as an ornament. 



Unlike the several naturalized species of Lantana in Florida, 

 the flowers of this do not vary in color, either on the same individual 

 or on difi'erent ones. 



The specimen from which the accompanying illustration was 

 made was collected on the reservation of Charles Deering at Cutler, 

 Florida, May 5, 1918.
