Lithops bromfeldii var. insularis forma sulphurea
This is a small interesting and beautiful lime-green monster with darker markings.
 

Lithops bromfieldii var. insularis cv. 'Sulphurea' Cole number C362
This is one of the most sought-after Lithops cultivars in which the leaves have lost their brown pigment resulting in various shades of green, opaque creamy yellow-green or lime green with numerous tiny darker green blotches on the face. The bodies are small and often odd looking, in
particular the variation in the size of the various heads in relation to one another. It is a fast clumper that can produce readily large mound with dozen of heads. The flowers are yellow. This cultivar comes true from seed.

Description: Lithops bromfieldii is a non-halophytic, medium sized Lithops, mostly about 25 X 20 mm with up to 10 or more heads, (mostly 2-4)
Body (paired leaves): Obconical, truncate, top surface slightly convex and bullate generally reddish coloured. The face is elliptical to kidney-shaped more or less equal with impressed valley-like channels and raised islands, and bold rubrications. The fissure is shallow, 4-8 mm; lobes conjunct. This species is characterized by impressed valley-like channels, raised islands, and bold rubrications and is quite variable.
Flowers: Yellow, small to large 25-35(-45) mm in diameter. Seeds yellow-brown, rugose.
This species is quite variable and the colours and face pattern varies in plant from different provenance.

Lithops bromfieldii comprises several more or less intergrading and distinct variety:

• Lithops bromfieldii var. bromfieldii L. Bolus (1934) Cole numbers: C040, C041, C279, C348, C368
  Medium sized with a bullate top surface and generally reddish coloured. The face has impressed valley-like channels and raised islands, sometimes indistinct and reduced to vague prominences with bold rubrications, sometimes scattered with dots, hooks and dashes in the channels. Margins are irregularly incise dentate or sinuate, with peninsulas. Windows partially closed or accasionally completely open.

Windows and channels various shades of transluscent brownish or reddish green, greenish red or dull greyish green. Rubrications bright to dark-blood red, orange-red. Dusky dots dull dark greyish green.

Shoulders, margins and islands as for the margins opaque light honey, pinkish brown or light orange-brown. Windows and channels transluscent dull green, dark greenish brown or greenish red. Rubrications dull blood-red.

• Lithops bromfieldii var. insularis (L. Bol) B. Fearn (1960) Cole numbers: C042, C043, C057
  Small to medium sized intermediate form between var. bromfieldii and var. mennellii and often similar to var. glaudinae but without lustrous dusky dots. Face opaque, transluscent; slightly rugose, margins indistinct, irregularly dentate with mostly small peninsulas. Windows usually occluded. Channels broad to narrow, sometimes reduced to mini-windows; often with lines tailing off into the margins. Islands fairly small, irregular or reduced to indistinct flecks. Rubrications often forming a broken network. Shoulders, margins and islands orange-brown, pinkish, yellowish, greenish or brownish grey or greyish brown. Windows and channels transluscent greenish red, reddish green, brown or greenish grey. Rubrications bright to dull blood-red, purplish red. Dusky dots dull dark greenish grey. as for the margins or a little lighter.

• Lithops bromfieldii var. mennellii (L. Bol) B. Fearn (1937) Cole numbers: C044, C283
  Medium sized form with rugose surface, pinkish-grey facial colour and very dark rubrications .Channels deeply impressed which branch and tail off into the marginal area and encloding airly large, raised islands and peninsulas. Margins and windows vaguely distinguishable. Rubrications filling the channels in anirregular network of lines, dots, hooks and dashes.

Dusky dots dull dark greyish green.

Cultivars:

• Lithops bromfieldii var. bromfieldii cv. 'White Nymph' Japanese cultivar obtained by Yasuhiko Shimada with white flowers, but otherwise indistinguishable from the type variety.

• Lithops bromfieldii var. insularis cv. 'Sulphurea' Cole number C362 Japanese cultivar obtained by Yasuhiko Shimada characterized by a creamy yellowish-green colour. The Latin name “sulphurea” means 'sulphur-coloured'. In Japan this form is known as 'Ki-Meigen'.

• Lithops bromfieldii var. mennellii "pale selection" Selected cultivar from Mesa Garden Nursery characterized by a paler creamy colour of the island, but otherwise indistinguishable from the type variety.

In the winter season the plant doesn’t need watering, the plant at this time extracts water from the outer succulent leaves, allowing them to shrivel away, and relocating water to the rest of the plant and to the new leaves that form during this period. This plant is best for a well lit area (Bright shade to full sun). Water sparingly only when warm, no water when cold.

This is a beautiful pale selected cultivated form with Grey/brown/orangish top, marked with distinct reddish or brownish lines and spots (see: surface pattern) and exhibiting a strong border.
