Haworthia arachnoidea var. nigricans (Haw.) M.B.Bayer

 nigricans: blackish, for the dark hues.

 H. arachnoidea var. nigricans  belongs to arachnoidea group. Size can vary from 3 cm up to 12 cm, it can be slowly proliferous in some localities. It is distinguish by the purplish colouration towards the tips of the leaves. The colour is much darker. The leaves are broader at the base, spines more large and sparser than for the species generally. Glabrous forms with pronounced keels are quite common. Some glabrous forms resembles mucronata var. inconfluens, which is distnguished by colour of the leaves - they are light green-yellowish and leaves have translucent margins and keel. 

Distribution map

H. arachnoidea var. nigricans distribution area is from Montagu / Barrydale in the West up to Oudtshoorn in the East. In the North it grows up to the Laingsburg, where it is possible connected to var. scabrispina - at Rooinek Pass, where H. isomorpha was described - it will be discussed later. There is a strong connection to mucronata var. inconfluens around Barrydale. South of Calitzdorp occurs a very small form, this was described as H. arachnoidea 'scottii' - see its own article. Near Vanwyksdorp interesting intermediate form between arachnoidea var. nigricans and mucronata was found (see photos below).

 It grows like other arachnoidea plants, so keep it more in shade - but in the other hand, this variety seems to be a bit more used to stronger sun light - it turns beautifully reddish when exposed. Propagation by seed or offset.
