Lithops julii is a stemless small to medium sized
cone-shaped pair of leaves that are separated by a 5-10 mm deep fissure
with (usually) conjunct lobes. It is usually whitish-grey to dark grey
but very variable in colour, some specimens being opaque whitish-grey
and almost uniform in colour, others opaque but strongly reticulated
with fine impressed brown markings, yet others with largely open
obscurely transluscent windows. The profile is truncate, the tops are
flat to slightly convex. Face slightly reniform.
Flowers: It produces a single white daisy-like flower emerges
from the fissure and is as large as the pair of fleshy leaves below.
Blooming season: From mid-summer through fall
Fruit: Seed capsules-loculetd.
Seeds: Yellow-brown to light yellow-brown
subspecies, varieties and forms:
(Dint. & Schwant.) N.E. Br. 1925 - Cole numbers: C063,
C064, C183, C297, C349 (chrysocephala) C205; (littlewoodii) C218.
The more distinctive feature of this plant is a brown 'lip-smear'
along the inner margins. The lip-smear occurs occasionally as a narrow
edging or lining all along the outer margins. The windows are more or
less occluded with irregular broad and distinct channels, often
obscure or reduced to a network of narrow, grooves. The channels have
often a very variable network of rubrications and lines. Islands are
large more or less distinct against the background of opaque channels.
Shoulders, margins and islands are whitish grey, sometimes tinged with
blue, mauve or pink. Windows and channels are grey-white with some
blue, mauve, pink, beige or brown or slightly translucent greenish
grey, greenish or yellowish brown. Margins rather obscure irregularly
dentate or sinuate, with a number of peninsulas.
Three main forms have been proposed and were even given varietal
but wild populations tend to have at least two and many have all three
of this forms variously intermingled . Distribution: Namibia

C230B, C259, C319, C323, C378
This is an extremely variable subspecies in colour, pattern and
rubrication. Face somewhat unequal, margins distinct irregularly
dentate, sometimes sinuate with quite large peninsulas; both inner and
outer margins usually edged with a brown lining.
occasionally reduced to a network of narrow grooves. Channels slightly
impressed. Islands regular in shape more or less large; usually
distinct. Rubrications appear in the marginal indentations, as a
series of marks. Shoulders, margins and islands light grey, often
tinged with pink, yellow, blue or green, or beige. Windows and
channels milky blue, pale pinkish, greenish or yellowish grey, or
mauve, pink or rust-brown; often with a brown or dark greenish-brown
smear thinly lining both inner and outer margins.
var. brunnea H.W. de Boer 1962 - Cole number: C179
Very similar to var. fulleri, but browner in colour. Colours:
Shoulders, margins and islands pale creamy, pinkish or bluish grey, or
beige. Windows and channels greyish, reddish or greenish brown, or
grey. Rubrications red.
var. rouxii (H.W. de Boer) D.T. Cole 1964 - Cole numbers:
C215, C216, C217, C324
Strictly related to var. fulleri, but marked with stitch-like marginal
rubrications. Margins with irregular indentations,and a distinctive
series of dark rubrications which resemble stitches.
subsp. julii cv.
'Peppermint Crème' 1999 Cole number: C297A
Very distictive blue-green form derived from only one specimen
collected by Leslie Pretorius in 1983 in Namibia. Margins and islands
very pale milky bluish green and shoulders a little lighter than the
margins. Lip-smears pale brownish green. Channels opaque pale milky
var. fulleri cv. 'Fullergreen' 1988 Cole number: C056A.
Shoulders, margins and islands light creamy greenish grey, margins
edged with a light brownish-green, especially in the indentations.
Windows and channels opaque greyish blue-green. Rubrications obscure
