E. tetragonmi. The flowers are very variable in size and colour, 
and even in our plant Mr. Law observes the coloui* is sometimes 
altogether purple; and Dr. Roxburgh remarks that the leaves 
are also very variable. 
Descr. Root annual. Stem erect, a foot and more high, 
simple below, panicled above, tetragonous; the angles more or 
less winged. Leaves sometimes broadly ovate, acute, becoming 
narrower upward, ovato-lanceolate, and even lanceolato-acuminate 
above, three- to five-nerved, glabrous, smooth at the margin, 
pale beneath. Flowers in a cyme or panicle, few (in our speci¬ 
men), or fin the native specimens) many-flowered: branches 
trichotomous, or dichotomous with a single-flowered peduncle in 
the axil, all tetragonous and slightly winged at the angle, with a 
subulate hractea at the base. Calyx deeply five-partite: the 
segments broadly ovate, aristato-acuminate, furnished with a broad 
wing on the keel, which is decurrent more or less on the angles 
of the footstalk. Petals large, obliquely obovate, acute, purple, 
white at the base. Stamens four, curved to one side. Filaments 
short. Anthers large, subulate, truncate and opening by an 
oblong pore at the extremity. Ovary ovate: style longer than 
the stamens: stigma two-lipped.
