Gen. Char. Calyx (fig. 1.) bell-shaped, in 5 rather deep, 
strap-shaped, pointed segments, the lower one the longest, and 
subtending the keel of the corolla. Corolla (fig. 2.) papilionaceous, 
of 5 petals; standard ^vexillumy (fig:. 4.) larger than the rest, 
striated, keeled and compressed at the back, depressed at the sides; 
wings (see figs. 3 & 5 ) inversely egg-shaped, about half the length 
of the standard ; keel (see figs. 3 & 6.) of 2 converging petals, 
rather abrupt, pointed, a little longer than the wings. Filaments 
(see figs. 8 & 9.) 10, united into one cylinder, splitting along the 
upper edge. Anthers roundish. Germcn (see fig. 8.) oblong. Style 
(see figs. 8 & 9 ) cylindrical, ascending. Stigma small, blunt. 
Legume (fig. 10.) oblong-rhomboid, turgid, sessile, scarcely longer 
than the calyx, of 1 cell, and 2 rigid elastic valves (see fig. 11). 
Seeds (see figs. 11 & 12.) few, kidney-shaped, roughish. 
The bell-shaped calyx, with 5 strap-shaped, pointed segments ; 
the large striated standard; and the turgid, sessile, few-seeded 
legume ; will distinguish this from other genera, with monadelphous 
stamens, in the same class and order. 
Three species British. 
ONO'NIS ANTIQUO'RUM. Ancient Rest-Tlarrow. Spiny Rest- 
Harrow. Ground Furze. Cammock. Petty Whin. 
Spec. Char. Stems nearly upright, spinous, with 1 or 2 sepa- 
rate rows of hairs. Lower leaves trifoliate, the rest simple; leaflets 
and leaves oblong, wedge-shaped, and entire towards the base. 
Flowers usually solitary. Lobes of the calyx shorter than the legume.
