The ultimate branchlets of the inflorescence in var. glabrescens Correll are 

 somewhat elongated and more laxly flowered than in var. limbatum. The calyx 

 ribs are also glabrous or are provided with only a few scattered hairs instead of 

 being densely pubescent as in var. limbatum. 



2. Limonium Nashii Small. Fig. 616. 



Plant 3-8.5 dm. high, the scape solid; leaves with a petiole to 16.5 cm. long, 

 Hnear-elliptic to narrowly spatulate or obovate, obtuse to rounded at the barely 

 mucronulate apex, narrowed into the petiole, to 17 cm. long and 45 mm. wide; 

 scape paniculately much-branched from near the middle; panicle 2-3 dm. across, 

 the somewhat fractiflex lax branches spreading-ascending or arcuate, the ultimate 

 branchlets compactly or loosely flowered; spikelets 1- to 3-flowered; outermost 

 bractlet ovate, acute to acuminate, mucronate, hyaline-margined, 1.8-2.5 mm. 

 long; middle bractlet ovate to oblong, somewhat erose at the obtuse to mucronate 

 apex, hyaline with a distinct midrib, 2.5-4 mm. long; innermost bractlet elliptic, 

 rounded to retuse or subacute at apex, hyaline-margined, 3.8-4.5 mm. long; 

 calyx obconic, glabrous to sparsely or rather densely pilose at extreme base and 

 often on one or two ribs for about half their length, 5-7 mm. long, the whitish 

 5-lobed limb erect; calyx lobes ovate-lanceolate, acuminate, 1-1.5 mm. long; 

 teeth very short and bifid or obsolescent; corolla violet to lavender; capsule 5-7 

 mm. long. 



On beaches, salt flats and marsh borders, in grasslands and in loose sand among 

 dunes along the Gulf Coast, June-Nov.; mostly from S.C, s. to Fla. and w. to 

 Tex. and n.e. Mex., rare n. of S. C. 



The inflorescence of this species is more laxly and openly branched than in 

 that of the eastern L. caroliniaman (Walt.) Britt. Plants ascribed to L. caroliniamim 

 var. compactum Shinners belong to var. Nashii. 



In our region var. angustatum (Gray) Ahles seems to be more southern in its 

 distribution than var. Nashii, being rather frequent on south Padre Island, Texas. 

 Its leaf blades are typically smaller than those of var. Nashii, being up to about 

 10 cm. long and 2.5 cm. wide. L. angustatum (Gray) Small, L. carolinianum var. 

 angustatum (Gray) Blake. 



Fam. 104. Styracaceae Dum. Storax Family 



Shrubs or trees commonly with stellate pubescence; leaves alternate, simple, 

 exstipulate; flowers regular, perfect; calyx adherent to the ovary or at least 

 to its base, entire or with 4 to 8 valvate teeth or lobes; corolla with 4 or 5 

 (rarely more) petals that are (in ours) united at base or rarely more; stamens 

 as many as or several times as many as the corolla lobes, free or adnate to 

 corolla tube; anthers elongate; ovary inferior or partly inferior in Styrax; style 

 one; fruit a drupe or capsule. 



A small family of about 180 species in 12 genera in warm temperate regions. 



1. Calyx adherent to whole surface of ovary; corolla 4-lobed; fruit ellipsoid to 

 ellipsoid-obovoid, 2- to 4-winged 1. Halesia. 



1. Calyx adherent only to base of ovary; corolla 5-lobed; fruit globular, wingless 

 2. Styrax. 



1. Halesia Ellis 



Shrubs or small trees, with large veiny deciduous leaves and snowy-white 

 flowers drooping on slender pedicels in clusters or short racemes, the pubescence 

 partly stellate; calyx inversely conical, 4-toothed, the tube ribbed; corolla openly 

 campanulate; petals 4, white, united at base or sometimes to above the middle; 

 stamens 8 to 16; filaments united into a ring at base and usually a little adherent
