A NEW NYSSA FROM FLORIDA 

 John K. Small 



With the acquisition of another species of Nyssa to the North 

 American flora, the two sections of the genus are evenly balanced 

 with three species each. For many years the ratio was two and 

 two. Then Nyssa acuminata of the coastal region of Georgia 

 was added to the aquatica-ogeeche group. Three decades later 

 the main subject of this note was added to the sylvatica-hiflora 

 group, which brought the ratio even again. The source of this 

 gum is the Apalachicola River delta region where so many en- 

 demic species of flowering plants are harbored. It grows in 

 company with Clijtonia monophylla and Cyrilla racemiflora, both 

 of which it resembles in habit of growth. It may be named and 

 described as: 



Nyssa ursina Small, sp. nov. A shrub with much-branched 

 stems and numerous branchlets or sometimes a small tree with a 

 trunk a decimeter in diameter and a narrow much-branched 

 crown: leaves numerous; blades elliptic, often narrowly so, to 

 spatulate, 2.5-7 cm. long, coriaceous, usually rounded at the 

 apex, entire, deep-green and somewhat shining above, much 

 paler beneath, glabrous, at least at maturity, short-petioled : 

 staminate racemes numerous on slender peduncles 1-2 cm. long; 

 sepals ovate to suborbicular, about i mm. long, obtuse; anthers 

 globose-ovoid to globose-reniform, nearly 1.5 mm. long, longer
