Description: Lithops leslieiSN|12964]]SN|12964]] var. hornii is one of the local form of the very variable Lithops leslieiSN|12964]]SN|12964]] that differs in a number of colour characters, but not sufficiently differentiated and often considered merely a local variant of the latter (if not the same). Its faces typically displays an orangish-brown or pinkish-brown colouring with coarser, irregular and relatively opaque greyish brown branching patterning, and seems a brown coloured var. venteri.
Habit: Lithops leslieiSN|12964]]SN|12964]] var. hornii branches more profusely than other varieties, and often forms groups with more than 10 heads. Each heads consists of two leaves closely pressed together or united, except for a central fissure across the top, from which the large yellow flowers are produced.
Bodies (paired leaves): Medium-large, rounded from above, profile truncated, top of lobes elliptic-reniform, flat, smooth, sometimes slightly convex; sides coloured purple-grey, brownish or green; windows always present, rarely ridged or fully open, dark-green, consisting of small irregular, extremely variable confluent areas; densely or sparsely covered with light ochre, orangish-brown, rusty brown or pinkish-brown irregular projections from the slightly raised margins; in these projections small round dark greyish-brown openings; outer margin distinct but very irregular, sonic laciniae being very short, others projecting into the window; inner margin nearly straight or provided with obtuse very short lobes, giving the whole margin a wavy appearance; on outer edge of the margins few or many irregular distributed more or less circular windows.
Flowers: Large yellow.
Blooming season: Autumn (in habitat blooms in April)
Fruits: Mostly 6-cambered.
Seeds: Reddish.

Subspecies, varieties, forms and cultivars of plants belonging to the Lithops lesliei group

Lithops lesliei (N.E.Br.) N.E.Br.: (var. lesliei) Cole numbers: C014, C020, C028, C036, C026, C151, C344, C352, C358. Deep rusty brown with brown windows; flowers golden yellow.
Lithops lesliei subs. burchellii D.T.Cole: Cole number(s):C302, C308. Distinguished from subsp. lesliei by colour and markings, and from var. venteri by the much finer meshlike markings and clavate marginal lines. Origin: RSA: CP, in small area NE of Douglas. It is probable that this subspecies occurs also in the military zone further to the NE, along the Vaal River.

Lithops lesliei C005A TL: Near Warrenton, South Africa cv. albiflora D.T.Cole: Extremely rare white flowering form, occasionally found in any one colony, but in all other respects the plants are indistinguishable from others in the same colony. They can therefore be identified only when in flower.
