1. Limonium angustatum (A. Gray) Small. Leaves basal, few ; blades linear, 4-7 

 cm. long, cuspidate, 1-nerved, narrowed into petioles which are somewhat shorter than the 

 blades and with dilated bases : scapes erect, about 3 dm. tall, with several scale-like clasp- 

 ing bracts sparingly branched above : bracts subtending the flowers broadly oblong, 4 

 mm. long, acute : calyx about 5 mm. long ; tube glabrous ; lobes 5, ovate, the connecting 

 membranes eroded. 



In salt marshes, Pine Key, Florida. 



2. Limonium Brasilia" nse (Boiss. ) Small. Leaves basal; blades oblong, 6-12 cm. 

 long, rounded or retuse at the apex, usually cuspidate or mucronate, gradually narrowed 

 at the base ; petioles about equalling the blades in length or surpassing them : scapes erect, 

 bearing a few scales, branched above, the slender elongated branches spreading : bracts 

 subtending the flowers broadly oval, 3 mm. long, eroded at the rounded apex : calyx 3-4 

 mm. long ; tube glabrous ; lobes round-ovate, about 5 mm. long, obtusish : corolla white. 



In salt marshes or on beaches, North Carolina to Florida. Also in South America. 



3. Limonium Californicum (Boiss.) Heller. Resembling L. Brasiliense in habit, 

 but stouter. Bracts suborbicular, abruptly pointed : calyx-lobes triangular, mucronate. 



In saline places, California, extending eastward along the southern border of the United States, 

 probably to within our range. 



4. Limonium Nashii Small. Leaves basal ; blades oblong or elliptic, sometimes 

 varying to narrowly obovate, 4-10 cm. long, rounded or notched at the apex, occasionally 

 mucronate, narrowed into petioles which are shorter than the blades or longer : scapes 

 erect, 3-7 dm. tall, furnished with a few scales, widely branching above, the tips of the 

 spreading branches recurved : bracts subtending the flowers oval, about 4 mm. long, obtuse : 

 calyx 6-7 mm long ; tube 4 mm. long, sparingly pubescent with soft hairs at the base 

 only ; lobes 5, triangular, slightly acuminate, more than 1 mm. long : corolla deep blue. 



In salt marshes, Georgia to Florida and Mississippi. 



5. Limonium Carolinianum (Walt.) Britton. Leaves basal ; blades elliptic or 

 oblanceolate, 4-12 cm. long, cuspidate, narrowed at the base ; petioles shorter than the 

 blades or usually longer : scapes erect, 2-6 dm. tall, bearing a few scales below, much 

 branched, the tips of the branches usually erect or curved upward : bracts subtending the 

 flowers suborbicular, about 4 mm. long, eroded at the apex : calyx 5-6 mm. long ; tube 

 bristly to above the middle with ascending or spreading hairs ; lobes 5, ovate, about 1 

 mm. long, acute : corolla 4-5 mm. broad, pale purple. 



In salt meadows, Labrador to Florida. 



6. Limonium limbatum Small. Leaves basal ; blades leathery, spatulate or oblong- 

 spatulate, 0.5-1.5 dm. long, obtuse or notched at the apex, prominently nerved beneath in 

 drying ; petioles shorter than the blades or rarely longer, margined : scapes erect, solitary 

 or several together, corymbosely branched, the branches zigzag, ascending : spikes in dense 

 terminal corymbs : bracts suborbicular or sometimes orbicular-oval, obtuse, often eroded at 

 the apex, hyaline-margined : calyx trumpet-shaped with a flaring limb, nearly 4 mm. long : 

 tube hirsute ; lobes broadly deltoid, apiculate : corolla bright blue. 



In alkaline soil, Texas and New Mexico. 



FAMILY 2. PRIMULACEAE Vent. PRIMROSE FAMILY. 



Caulescent or scapose herbs, various in habit. Leaves alternate or opposite, 

 or whorled, sometimes all basal, without stipules : blades commonly simple. 

 Inflorescence variously disposed. Flowers perfect, usually regular. Calyx of 

 4-9 partially united sepals, commonly persistent. Corolla hypogynous, often 

 gamopetalous, with 4-9 manifest lobes, or rarely wanting. Androecium of as
