10. DIANTHERA Gronov. (WATER-WILLOW.) 
Perennial herbs growing in water or wet places, with entire leaves, 
purplish flowers in axillary peduncled spikes or heads, 5-parted calyx, 
deeply bilabiate corolla (upper lip erect and notched, lower spreading 
and 3-parted), 2 stamens with anther-cells separated and somewhat un- 
equal, and an obovate flattened pod contracted at base into a short

* Glabrous: flowers capitate or spicate on a long and naked axillary peduncle. 
1. D. Americana L. Stem 3to9dm. high, sulcate-angled : leaves narrowly lan- 
ceolate, 7.5 to 10 cm, long, tapering at base, subsessile: peduncles mostly exceeding 
the leaves, capitately several-flowered: corolla pale violet or whitish, less than 12 
mm. long; base of lower lip rugose.—-In water, extending from the Atlantic region

2. D. ovata Walter. Stem lower, from a creeping base or rootstock, mostly slen- 
der: leaves from oblong or obovate-oblong to linear-lanceolate, sessile or slightly

humilis Eng. & Gray).—Mnuddy borders of streams, from the Gulf States, near the 
coast, to Texas. 
3. D. parviflora Gray is only known from an imperfect specimen, which indi- 
cates that it is like the preceding; but leaves shorter (2.5 cm. or 80 long), lanceolate 
from a broader and rounded subsessile base, the younger with a few hairs, and the 
inflorescence puberulent, with also some short-stipitate glands,— Western Texas,”
