Morphology General Habit
Plants tufted.
Morphology Stem
Stems erect to spreading, laxly and irregularly branched, green, 5–12 cm long, 0.7 cm wide, strictly and acutely 4-angled, tubercles inconspicuous.
Morphology Leaves
Leaf rudiments ascending, 4 mm long, persistent.
Morphology Reproductive morphology Flowers
Flower-bearing apical region terete to 4-angled, up to 26 cm long, often spreading nearly horizontally
Morphology Reproductive morphology Inflorescences
Inflorescences usually 1-flowered, shortly bracteate; pedicel directed downwards, ± 1 cm long
Morphology Reproductive morphology Flowers Corolla
Corolla pale yellow-green, basally spotted with red, stellate; corolla lobes fused basally into a tube 0.5 mm long; lobes ± 8 × 1 mm, basal 1 mm erect, with vibratile purple clavate cilia 1 mm long, apical 7 mm horizontally spreading, linear-lanceolate, almost completely reflexed along the midrib, upper face pubescent to pilose, cilate with simple hairs 1 mm long
Morphology Reproductive morphology Flowers Corona
Gynostegial corona atop a stalk 1 mm long, pale yellow; interstaminal corona lobes spreading horizontally, 0.75 mm long, dark red, bifid into triangular, fairly straight, hardly spreading lobules; staminal corona lobes linear, ± 2 mm long, apically obtuse, connivent above style-head, basally mottled pale red to pink, apically dark red.
Ecology
Isolated rocky, gneissic hill; 450–600 m
Note
This Teita endemic appears like a yellow-green flower variant of Caralluma arachnoidea with less subulate and less spreading interstaminal lobules. However, molecular studies (Bruyns et al. in Taxon 50: 1031–1043, 2010) placed it in sister relationship to C. turneri. With the latter (and with C. arachnoidea) it shares a highly similar corona structure, but not the mobile and drooping corolla lobes.
Distribution
