1916] Blake, — Limonium in North America and Mexico 65 



glaucescent. Leaves obovate, rounded or retuse at the barely mu- 

 cronulate apex, narrowed into the petiole, thick, leathery, venose, the 

 blade 6-14 cm. long, 2.4-4.5 cm. wide, on petioles 5.5-10 cm. long. 

 Scape stout, much branched from below the middle upwardly. Panicle 

 large, 2.3-3 dm. wide and more, the branches divergent-ascending, 

 the 2-flowered spikelets densely and distichously aggregated in 0.8- 

 1.4 cm. long spikes on the ultimate branchlets. Outermost bractlet 

 ovate-orbicular or orbicular, acute or acutish, mucronate or apiculate, 

 hyaline-margined, 1-1.4 mm. long; middle oblong-oval, retuse at 

 apex, hyaline with green midrib, 3 mm. long; innermost very firm, 

 elliptic, rounded or retuse at apex, hyaline-margined, 3-3.5 mm. long. 

 Calyx trumpet-shaped with wide-spreading limb, ca. 3.7 mm. long, 

 two or three of the ribs pubescent to middle, the others generally 

 only at extreme base or not at all; lobes deltoid-ovate, obtuse to 

 acute, ca. 0.7 mm. long; intermediate teeth depressed -deltoid, about 

 0.2 mm. long, or obsolescent. "Corollas light blue." Plate 119,
