628 OROBANCHE;E. 
Radicle superior, remote from the umbilicus.—Usually para- 
sitical, leafless, rather fleshy, rufescent, scaly herbs. Flowers 
terminal, solitary, spicate, or racemose. 
This is a very natural family, well distinguished from the pre- 
ceding by their permanent corolla, unilocular ovarium, centri- 
fugal embryo, and peculiar economy, in being for the most part 
parasitical herbs, destitute of proper leaves, and of the green 
colour common to other plants. The seeds are attached to the 
narrow, depressed placentze, formed by the united edges of the 
valves. The embryo is placed in the ventral side of the seed, 
and at the opposite extremity from the hilum, resembling a 
minute, nearly globular homogeneous mass, and is, therefore, 
probably devoid of true cotyledons. In all these respects the 
genera Obolària and Tózzia seem to agree, but differ in having 
proper leaves, and in being terrestrial. |

Stamens 4, didynamous. Stigma capitate, emarginately 2-lobed, 
Ovarium glandular at the base. Capsule 1-celled, 2-valved ; 
valves dehiscing laterally, but joined at the base and apex. Pla- 
centas parietal, 2 in each valve.—Parasitical, fleshy, usually 
simple, rarely branched, scaly, erect herbs. Flowers sessile, 
erect, solitary, in the axils of the floral scales. There is a fleshy 
gland that girds the ovarium. Filaments usually hairy, flat at 
the base. Anthers glabrous ; cells mucronate at the base. 
Secr. I. Sepals free, or combined in front at the lower part,
