7. Ii. papillosam, T. Muell. in Linnaa, xxv. 370, and PL Vict. i. 46. 

 An erect, branching annual, usually under 6 in., but, according to P. Mueller, 

 sometimes 1 ft, high or more, the stems covered with little transparent papillag, 

 and exhaling an unpleasant scent. Eadical leaves petiolate, often 3 in. long 

 or more, linear-oblong, coarsely toothed or irregularly pinnatifid, the upper 

 ones lanceolate or linear-cuneate, with a few remote teeth, and clasping the 

 stem by their auricled base, -§- to 1 in. long, and all glabrous. Flowers very 

 small, without petals, and with only 4 stamens. Fruiting racemes mostly 2 

 to 4 in. long, with rigid, flattened, rather spreading pedicels, of about 3 lines. 

 Pod oboyate, about 2 lines long, the valves winged only above the middle, form- 

 ing 2 rounded terminal lobes, a little more than \ line long, with the stigina 

 sessile in the rather narrow sinus. Seeds exuding a viscid, clear mucilage in 

 great abundance.

8. L. foliosum, Besv. Joimu BoL iii. 164 and 180 ; BC. Prod. I 206. 

 A low, straggling, glabrons herb, apparently perennial, with, hard irregularly 

 divaricate branches, sometimes attaining 2 feet, but often very much smaller. 

 Leaves mostly oblong-cuneate, -I to 1 in. long, bnt sometimes lanceolate or 

 almost linear and nearly 2 in. long, or short and obovate, usually with a fc^v 

 coarse teeth at the top, sometimes toothed from the base or piimatifid with 

 short entire or even toothed lobes, usually narrowed below the middle, but 

 always with a broad balf-stem-clasping base, and sometimes auricled. Flowers 

 very small. Petals on short slender claws, with a minute white ovate lamiua. 

 Fruiting racemes 2 to 3 in. long, often becoming lateral by the elongation of 

 leafy shoots, with spreading pedicels of about 2 lines. Pods ovate or ellipti- 

 cal, flat, 2^ to 3 hues long, sometimes almost wingless, but usually the very 

 narrow wings form 2 minute, obtuse, terminal points, between which is the 

 \Qxy shoi-t style. Seeds exuding a not very thick mucilaginous coat. 1^-

This species is chiefly distinguished from L. rudei-ale by its coarser habit, usually broaJer 

 leaves and inore perfect flowers, and by the pods usually twice the size. It represents m 

 Australia the Z. pucidinm of the Pacific Islands, which has a nearly similar pod and flower?, 

 hut most of its leaves are narrowed into a petiole, without the broad stem-clasping base ot 

 the Australian plant. 



9. L. mderale, TJyin,; BG, Prod. i. 205. An annual, biennial, or 

 sometimes perennial, glabrous or with a few minute scattered hairs, coni- 

 un^ncing to flower when very small, but growing out to 1 or even 2 ft.j ^^'^^'^
