_ obovate, 4-10 cm. long, rounded or notched at the apex, occasion- 
ally mucronate, narrowed into petioles which are shorter than the 
blades or longer; scapes erect, 3-7 dm. tall, furnished with scale- 
like bracts, 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, the tube sparingly 
pubescent with soft hairs at the base only, the 5 segments tri- 
angular, slightly acuminate, more than I mm. long; corolla deep 
blue. 
In salt marshes, Florida. Summer and fall. 
Specimens of a beautiful and previously undescribed species of 
Limonium have been in our herbaria for some years; they are from 
northern and eastern Florida and represent a species of more 
slender and more graceful habit than that of Limonium Carolint- 
anum. 
The following synopsis and comparison of the diagnostic char- 
acters of Limonium Nashii and L. Carolinianum will serve to make 
clear the difference between the two species : 
Limonium Nashiw. Branches of the panicle spreading, the tips 
recurved ; bracts subtending the flowers oval; calyx-tube spar- 
ingly pubescent at the base; calyx-segments triangular, slightly 
acuminate. 
Limonium Carolintanum. Branches of the panicle ascending, 
the tips curved upward; bracts subtending the flowers subor- 
bicular ; calyx-tube bristly-pubescent ; calyx-segments ovate. 
The species has been collected as follows: 
Florida: Chapman; St. Marks, Aug. 1843, Rugel; Titusville, 
Brevard County, July 31, 1895, Nash. no. 2305. 
¥ EupaTorIum PETALODIUM Britton. 
Perennial, bright green. Stems erect, 3-7 dm. tall, simple 
below, corymbosely branched above, somewhat rough with rigid 
hairs; leaves mainly opposite (a few of the upper ones alternate), 
oblong to lanceolate, 2-8 cm. long, obtuse or rarely acutish, 
bluntly serrate or crenate-serrate, except the entire more or less 
cuneate base, glabrous or sparingly pubescent on the nerves be- 
neath, sessile; peduncles and pedicels pilose ; involucres trumpet- 
shaped, 9-10 mm. high, the bracts linear-spatulate, the outer ones 
abruptly acuminate, the inner ones mucronate, slightly surpassing 
the flowers, petal-like, white; corolla 3 mm. long, the segments 
ovate, spreading; pappus about equalling the corolla; styles ex- 
serted; achenes black, nearly 3 mm. long, 5-angled. 
In dry pine barrens, Florida. Summer and fall.
