Description: Lithops halliiSN|13080]]SN|13057]] is one of the most variable white flowering species related and often synonymized to Lithops juliiSN|13004]]SN|13037]] (including Lithops fulleriSN|13046]]SN|13046]]). Furthermore it shares several characteristics with Lithops hookeriSN|13037]]SN|13004]] and Lithops salicolaSN|13057]]SN|13080]]. It forms small clumps with up to 6 or more heads, mostly 2-3. The Brown form shows mainly shades of reddish-brown with regular fine to broad interlacing network of channels.
Bodies (paired leaves): Medium to large, 20-47 mmlong 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 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 channels with 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".

We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present.
Read More... Cultivation and Propagation: They need an open mineral, fast draining mix and the maximum amount of light you are able to give them.
The basic cultivation routine is: Stop watering after flowering. Start watering after the old leaves completely dry. (Usually late March or Early April) Water freely during the growing season, soak the compost fully but allow it to dry out between waterings, no water when cold. Some growers fertilize frequently, some hardly ever. Keep them dry during the winter. Nearly all problems occur as a result of overwatering and poor ventilation especially when weather conditions are dull and cool or very humid. This plant is best for a well lit area (Bright shade to full sun). But don't be afraid even the best growers have plants that mysteriously dry up, or leave during the night.
