anthers twisting spirally, single slender style with capitate 2-lipped 
stigma, and oblong-ovate to fusiform pod. 
* Flowers small: corolla-lobes 3 to 5 mm. long, much shorter than the tube: anthers oblong. 
1, E.Texensis Griseb. Slender, diffusely much branched above into a loose panicu- 
late cyme: leaves linear or the lowest lanceolate and the uppermost reduced to sub- 
wate bracts: flowers all slender-pediceled: corolla (light rose color) with very slen- 
der tube 8 to 10 mm. long, and lanceolate-oblong lobes (4 mm. long) which become 
lanceolate-linear, longer, and acute.—Common on rocks and hills. 
*™ Flowers larger: corolla-lobes 7 to 12 mm. long, but more or less shorter than the tube: 
anthers linear. 
2. EB. Beyrichii Torr. & Gray. Slender, at length fastigiately much branched: 
leaves linear, the uppermost nearly filiform: flowers very numerous, fastigiate- 
cymose ; corolla-lobes linear-oblong and becoming linear, 10 mm. long, in age by involu- 
tion becoming acuminate,—From Arkansas to southern and western Texas. 
3. E. calycosa Buckley. Paniculately or somewhat cymosely branched: leaves 
from narrowly oblong to lanceolate or linear: inflorescence loose; pedicels mostly 
as long as the calyx or the whole flower: corolla-lobes oval or oblong, obtuse, 7 to 
10 mm. long; the tube usually equaled by the calyx.—Western Texas and adjacent 
Mexico, On the stony hills of western Texas is var. NANA Gray, which is lower, 
with leaves all linear and inflorescence corymbose. 
2. SABBATIA Adans. 
Biennials or annuals, with slender stems, cymose-panicled handsome 
(white or rose-purple) flowers, 5 to 12-parted calyx with slender divi- 
sions, 5 to 12-parted rotate corolla, 5 to 12 stamens with anthers soon 
recurved, 2-cleft or parted slender style, and globose or ovoid coriaceous 
pod. 
* Corolla 5-parted, rarely 6 or 7-parted. 
1. 8. calycosa Pursh. Diffusely forking, pale, 3 dm. high or less: leaves oblong 
or lance-oblong, narrowed at base: calyx-lobes foliaceous, spatulate-lanceolate, ex- 
ceeding the rose-colored or almost white corolla.—Seacoast and near it. 
2. S. campestris Nutt. Divergently branched above: leaves ovate with subcord- 
ate clasping base, on the branches lanceolate: calyx equaling the lilac corolla, the 
lobes slender and tube short (nearly or quite inclosing the retuse pod).—Prairies of 
Arkansas and Texas. 
* * Corolla 8 to 12-parted, large and showy. 
3. S. gentianoides Ell. Stem strict: radical leaves in a rosulate tuft, obovate 
or oblong; cauline very narrowly linear; uppermost involucrating the terminal 
cluster of 3 to 5 (sometimes 1 or 2) nearly sessile flowers: calyx-lobes lanceolate-sub- 
ulate, very much shorter than the spatulate corolla lobes.—Extending into Texas 
from the pine-barrens of the Gulf States. 
3. HUSTOMA Salisb. 
Glaucous large-flowered annuals, with more or less clasping and con- 
nate leaves, slender terminal and more or less paniculate 1-flowered 
peduncles, 5- (rarely 6-) parted calyx with long-acuminate lobes, cam-
