886 Orobanchaceae. 
1-celled, more or less dehiscing with 2 valves. Seeds very numerous, 
small; testa often foveolate-reticulate; endosperm fleshy. Embryo 
globose, of few cells, undifferentiated. — Annual or perennial parasitic 
herbs, almost perfectly destitute of chlorophyll, variously coloured, 
but never green. Stems usually simple, solitary or fascicled, more 
or less fleshy. Leaves reduced to, often fleshy, scales, few or many. 
Flowers in terminal racemes or spikes, supported by bracts and 
often also by bracteoles. 
Species over 130, almost exclusively in the northern hemisphere,’ 
particularly in the warm-temperate regions. 
A. Calyx tubular-campanulate, obtusely 4—5-lobed. . . 1. Cistanche. — 
B. Calyx campanulate, acutely 3—5-dentate or 3—5-fid 
or split to the base in front and on the back . . . 2. Orobanche. 
508. (1.) Cistanche Hoffm. et Link. 
Calyx persistent, tubular-campanulate, 4- or 5-lobed; lobes 
obtuse, rounded, subequal or the two posticous narrower. Corolla 
tubular below, more or less funnel-shaped above, more or less curved 
or at length abruptly bent; limb spreading, oblique, 5-lobed; lobes 
broad, equal or nearly so. Stamens 4, didynamous, subexserted, 
inserted deep down in the corolla-tube; anthers usually densely 
bearded and coherent by the hairs; cells parallel, often acute or 
mucronate at the base. Ovary 1-celled, with 4 distinct placentas, 
many-ovuled; style curved at the apex; stigma large, orbicular. 
Capsule 2-valved, dehiscing in the median plane. Seeds very 
numerous, minute, foveolate-reticulate. — Parasitic plants, variously 
coloured, destitute of chlorophyll, glabrous or cobwebby. Stems 
succulent, often bulbously thickened at the base, simple. Leaves 
reduced to fleshy scales. Flowers bracteate and 2-bracteolate, spicate, 
rather large, white, yellow or purplish. 
Species about 10 in the dry regions of Portugal, Spain, North Africa, 
and through the Orient to India.
