Lithops bromfieldii L. Bol. (1934)


var. bromfieldii



     

Origin:


Collected by H. Bromfield in September 1933 (NBG 2286/33), and named for him.

Distribution:


RSA: CP, within 30 km of the Orange River, to the NE, E and SE of Upington; with reported outliers, unfortunately still not confirmed, to the SE, near Marydale. TL 'near Upington', almost certainly to the NE (C040) - not SW, where var. insularis occurs.
Stone: White and red-stained (iron oxide) quartzite; greyish, brownish or reddish sheared quartzite.

Description:


Distinguished by its generally reddish colour, bullate top surface with impressed valley-like channels and raised islands, and bold rubrications.
Profile truncate; top surface flat to slightly convex; fissure shallow, 4-8 mm; lobes conjunct.
Face flush, elliptic-reniform; lobes equal-unequal; opaque + transluscent; usually distinctly rugose.
Margins usually distinct but rather irregularly dentate or sinuate, with peninsulas.
Windows usually occluded, very rarely completely open.
Channels broad to narrow, irregular, usually distinctly impressed and valley-like.
Islands few to many, small to large, usually ± humped, sometimes rather indistinct and reduced to vague reef-like promininences shoaling off at the edges.
Rubrications usually numerous bold lines forming an irregularly branched broken network, sometimes scattered dots, hooks and dashes in the channels.
Dusky dots seldom visible without a lens, fairly numerous, mostly in the channels, sometimes in the islands.
Colours: Margins and islands opaque pale pinkish yellow, deep cream, pale orange-yellow or pinkish grey, the margins sometimes a little deeper in colour. 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 as for the margins or slightly lighter.
Size: Medium, facial diameters up to 32 X 23 mm, mostly about 25 X 20 mm. Number of heads up to 10 or more, mostly 2-4.

Flowers:


Yellow, small to large, up to 45 mm Ø, mostly 25-35 mm Ø.
Seed capsules mostly 5-merous (94%), otherwise 6-merous (4%), or 4- and 7- merous (2%). Profile boat-shaped, top flat. Face broadly elliptic, with hinge-rim, up to 10,5 X 8 mm, mostly about 7,5 X 6 mm.

Lithops bromfieldii L. Bol. (1937)


var. insularis (L. Bol) B. Fearn (1960)



     

Origin:


Collected C.W. Wilmot in 1934 or earlier (NBG 1353/34). Latin insularis 'pertaining to the island'.

Distribution:


RSA: CP, in a small area within 5 km on both sides of the Orange River, to the NE and E of Keimoes. TL 'an island (near) KeimoesKeimoes, in the Orange River'.
Stone: Feldspathic quartzite; sheared pegmatite. Colours greyish brown, pink, brown.

Description:


Intermediate between var. bromfieldii and var. mennellii, being more brown and less red than the former, and having wider, more transluscent channels than the latter. Some specimens are very similar to var. glaudinae but have few or no lustrous dusky dots.
Profile truncate; top surface flat to slightly convex; fissure shallow, 3-6 mm; lobes conjunct.
Face flush, elliptic-reniform; lobes equal-unequal; opaque + transluscent; slightly rugose.

Windows usually occluded, seldom ± completely open.
Channels slightly impressed, broad to narrow, sometimes reduced to mini-windows; often with lines tailing off into the margins.
Islands few to many, mostly fairly small, irregular, often reduced to rather indistinct flecks.
Rubrications usually scattered dots, dashes and hooks, sometimes with longer lines forming a broken network.
Dusky dots usually not visible without a lens, fairly numerous, scattered in the channels.

Lithops bromfieldii L. Bol. (1934)


var. insularis
acf 'Sulphurea' (1977)



Origin:


This form appeared in seedlings grown from seed obtained in 1958 from the National Botanical Gardens of South Africa, and cultivated by Yasuhiko Shimada, Japan. Its source in habitat is unknown. Originally published as L. bromfieldii var. insularis f. sulphurea Y. Shimada. Latin sulphurea 'sulphur-coloured'. In Japan this form is known as 'Ki-Meigen'.

Stone: Micaceous quartzo-feldspathic gneiss; granitic gneiss. Colours grey-white, brown, pink.

Description:


Distinguished by its rugose surface, pinkish-grey facial colour and very dark rubrications.
