Description: Lithops halliiSN|13080]]SN|13057]] is one of the most variable white flowering species with a rugose surfacerelated and often synonymized to Lithops juliiSN|13057]]SN|13037]] (including Lithops fulleriSN|13058]]SN|13046]]). Furthermore it shares several characteristics with Lithops hookeriSN|13080]]SN|13004]] and Lithops salicolaSN|13004]]SN|13080]]. Plants named Lithops salicola var. reticulataSN|13046]]SN|13058]] are probably derived by hybridization of Lithops halliiSN|13037]]SN|13057]] and Lithops salicolaSN|13057]]SN|13080]]. It forms small clumps with usually 2-3 heads, but occasionally with up 6 or more heads.
Bodies (paired leaves): Medium to large, 20-47 mm long and 15-30 mm wide at the fissure. Broadly kidney shaped, top surface truncate, mostly flat, sometimes slightly convex; fissure shallow, 4-7 mm; lobes conjunct. Face flush somewhat reniform; lobes equal-unequal; opaque, slightly rugose. This species is fairly easy to identify and shows shades of reddish-brown with regular fine to broad interlacing network of blood-red or brown channels with few or many mostly small islands and fairly distinct irregularly dentate margins. It never has a brown line along the lip of the fissure. Shoulders as for the margins, or lighter, or milky bluish grey.
Flowers: The blooms are white 20-45 mm in diameter.
Blooming season: Autumn.
Fruits: (5-)6(-7)-loculed capsules up to 6-10 mm long 4-6,5 mm wide, boat-shaped, top flat to slightly convex. Face narrowly elliptic.
Seeds: Light yellow-brown to yellow-brown, smooth to rugose.
Remarks: After flowering in the autumn and extending through winter season the plant doesn’t need watering, but they will still be growing, the new bodies will be increasing in size extracting water from the outer succulent leaves, allowing them to shrivel away. In fact the plant in this time extracts water and nutrient stored in the outer succulent leaves, allowing them to dehydrate relocating the water to the rest of the plant and to the new leaves that form during this period until the old leaves are reduced to nothing more than "thin papery shells".
