  Lithops bromfeldii var. mennellii "Pale selection" CACTUSPEDIA       

 


Lithops bromfieldii var. mennelli "Pale selction"
This is a medium sized plant, readily clumping.  Distinguished by its rugose surface, pale pinkish-grey facial colour and very dark rubrications. Yellow flowers in autumn.
 

Description: Lithops bromfieldii is a non-halophyticmedium sized Lithops, mostly about 25 X 20 mm with up to 10 or more heads, (mostly 2-4)
Bodies (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.

    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.

    Medium sized characterized by many dusky dots with a shining metallic reflex. The face is opaque, more or less translucent and smooth with narrow, irregular channels, numerous, small, irregular islands with indistinct flecks composed of small opaque dots. The margins with small irregular peninsula are quite indistinct. Rubrications partially visible, sometimes with longer lines forming a sparse broken network. 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. Face and shoulders pinkish grey, creamy grey, greenish grey or light milky grey. Channels dull dark greyish green; it is often difficult to distinguish between the channels and concentrations of dusky dots. Rubrications dark red, red-brown or purplish red. Dusky dots dull dark greyish green.

Cultivars:

  • Lithops bromfieldii var. bromfieldii cv. 'White Nymph' Japanese cultivar obtained byYasuhiko 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'.

In the winter season the plant doesn’t need watering, the plant in this time extracts water from the outer succulent leaves, allowing them to shrivel away, 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.
