Annual. Stem erect, about 3 feet high, branching, armed with small 
prickles, and when broken or wounded discharging a coloured sap. 
Leaves alternate, sessile, embracing the stem, lobed and angled somewhat 
glaucous, glabrous, but with the margins and veins underneath armed with 
prickles. Floivers solitary, axillary. Peduncles 1 — 3 inches long. Ca- 
lyx caducous. Leaflets broad, oval, concave, prickly, with the dorsal horn 
compressed and projecting beyond the summit. Petals 6, obtuse, much 
larger than the calyx, yellow. Stamens very numerous as long as 
the germ. Germ superior, furrowed, spiny. Style very short. Stigma 
dilated, 5 lobed with the lobes reflected, forming 5 cylindrical tubes. Cap- 
§ule oval, spiny, divided about half way down into 5 valves; 1 celled. Seeds 
numerous, globose, reticulate, attached to the interior angle of the valve. 
The variety with white flowers is an ornamental plant, and is probably 
& distinct species, but the notes which I formerly took have been mislaid, 
and I have had no opportunity for a few years past of comparing the two 
plants in a living state. 
Grows in dry soils around buildings and is probably a naturalized 
exotic 
Flowers June to August.
