Calix none. Corolla 6-parted, stellately 

 spreading; segments linear, acute. Capsule 

 roundish, with 3 angles, S-celled, dissepiment 

 obsolete. Seeds numerous, minute, subterete 

 and caudate, attached to the margins of the 

 valves. 



Roots cespltose, fibrous; leaves irideous, compressed 

 and attenuated, sempervirent, very narrow, furnished 

 with distinct sheathes and distichally imbricated. Scape 

 sheathed, nearly naked; flowers few, racemose, pedun- 

 cles solitary, separately sheathed, about the middle bl- 

 bracteate. Stamina 9 to 12. 



Species. 1. P.tenuifolia. Rare. Abundant in a single lo- 

 cality, a few miles south of Wilmington, N. Carolina, near 

 the entrance of an extensive and open swamp. Obs. Fi- 

 bres of the root nearly scarlet, sheathing- base of the 

 leaves of a fine pink red, leaves deep green, tenaceous and 

 arid; racemes 6 to 9 flowered; flowers nearly saffron yel-

 seciion oVFofeldio, which I have called Triantha, but dif- 

 fers much in the form of the flower as well as in the habit, 

 and number of stamina.
