valves half-septiferous, or half of the” dissepi- | 
ment adliering to each valve after the opening 
of the capsule, and thence semibilocular; one of 
the most remarkable characters of the Natural 
Order Acanthi of Jussieu. a 
Stemless perennials, producing scapes entirely: vested 
with subulate coriaceous and almost imbrieate bractes; 
bearing flowers towards the summit; flowers imbricate, 
and bibracteolate, a little ringent. A oes nearly allied: 
to Justicia. 
Species. 1. E. Caroliniensis. There are 2lso 2 other : 
species in India. In the £. imbifodta the bracteal scales are 
3-toothed. Sm

Calix 5-parted or s.cleft, often with 3 bractes. 
Tube of the Corolla gibbous; border bilabiate;. 
_ the upper lip emarginate, the lower trifid. Fila- 
- ments 2, each with a single or double anther. 
Stigma 1. Capsule attenuated, below opening 
with an elastic spring from the summit to the 
base. Dissepiment contrary, growing from the 
centre of each valve. Seeds few, lenticular. 
Herbaceous or shrubby, leaves rarely verticillate, and 
still more rarely alternate; a few have axillary spines; _ 
flowers solitary or spiked, axillary or terminal. The spe- 
cies in the United States have opposite leaves, with short 
spikes upon long, axillary, peduncles, and are subaquatic, 
usually along the margins of the larger rivers, or in ditches 
in their vicinity. 
Spectres. 1. J. pedunculosa. 2. humilis. 3. brachiata of 
Puxsu. All the North American species produce 2 
anthers upon each filament, each anther 1-celled; hence 
many species of this extensive genus were thrown into 
‘called Dianthera by Linnzus and Jussieu. They - 
are, however, at present united. 
Oxs. Not a species of this extensive genus existsin 
Europe; they are, in general, tropical plants, manyofthem
