54. HUERNIA, R. Br.; Benth, et Hook. f, Gen. Pl. ii. 784. 
Calyx 5-partite. Corolla campanulate or broadly cup-shaped, or 
with a campanulate tube and spreading lobes, 5—6-lobed, with the base 
of the sinuses between the lobes produced into small triangular teeth, 
valvate in bud. Corona double; outer corona of 5 free or connate 
spreading lobes, arising at the base of the staminal-column and sessile 
on, or adnate to, the base of the corolla; inner corona of 5 simple 
lobes arising at the top of the filament part of the staminal-column, 
incumbent on the backs of the anthers and often produced beyond them 
into erect horns. Staminal-column arising from the bottom of the 
corolla; anthers inflexed-ascending or sub-horizontal, not appendaged. 
Pollen-masses inflexed-ascending or sub-horizontal, pellucid along the 
upper part of the inner margin, solitary in each anther-cell, attached 
in pairs to the pollen-carriers by short caudicles ; pollen-carriers with a 
wing-like expansion on each side, varying from dark reddish-brown to 
black. Follicles narrowly fusiform, smooth. Seeds crowned with a tuft 
of hairs.—Succulent perennial leafless herbs, branching at the base. 
Stems 4—6-angled, thick and fleshy, toothed along the angles. Flowers 
pedicellate, of moderate size, in few- or many-flowered cymes at the base 
of the young shoots. 
Species several, mostly natives of South Africa, 1 in Arabia.

the tube and lobes.
