DIANDRIA. MONOGYNIA^ 1 1 



valves half-septiferoys, or half of the dissepi- 

 ment adhering to each valve after the opening 

 of the capsule, and thence seniihilocular; one of 

 the most reniaikahle characters of the Natural 

 Order Jicanthi of Jussieu. 



Stemless perennials, producing' scapes entirely vested 

 with subulate coriaceous and almost imbricate bractes; 

 bearing- flowers towards the summit: flowers imbricate, 

 and bibracteolate, a little ringent. A genus nearly allied 

 to Justicia. 



Species. 1. E. Caroliniensis. There are also 2 other 

 species in India. In the E. imbricata the bracteal scales are 

 S-toothed. , 



18. JUSTICIA. i. 



Calix .5 -parted or 5-cIeft, often with 3 bractes. 

 Tube of the Corolla gibbous; border bilabiate; 

 the upiier\\\i eniarginate, 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 verticiilate, end 

 still more rarely alternate; a few have axillary spines; 

 flowers solitary or spiked, axillary or terminal. The spe- 

 cies in the United States ha'-e opposite leaves, with short 

 spikes upon long-, axillary, peduncles, and are subaquatic, 

 usually along the margms of the larger rivers, or in ditches 

 in their vicinity. 



Species. 1. J. pedunaihsa. 2. hnmilis. 3. brachiata of 

 PuRSH. All the North American species produce 2 

 anthers upon each filament, each anther 1-ceiled; hence 

 mjtny species of this extensive genus were thrown into 

 another called Dianthera by Linnaeus and Jussieu. They 

 are, however, at present united. 



Obs. Not a species of this extensive genus exists in 

 Eunpe; they are, in general, tropical plants, many of them 

 spiendid. Of luO species 3 only are as yet discovered in- 

 digenous to the United States, — 35 in India and its islands 

 — 8 m Arabia Felix — 3 in Cnina, of which one is also com- 

 mon to Arabia — 1 in Japan — 5 m Africa, 4 of them at the 

 Cape of Good Hope and 1 at Sierra Leone— 1 in New Hoi-
