DIDYNAMIA— ANGIOSPERMIA. Orobanche. 147 



In bushy places on a barren gravelly soil, growing on the roots of 

 Broom or Furze. 



Perennial, June, July. 



iioo^ of a few fibres. Stem about a foot high, erect, dusky, un- 

 branched, angular, hollow, fleshy, clothed, like every other part, 

 with short, rough, glandular pubescence, and beset with scattered, 

 lanceolate, upright scales, in the place of leaves ; the base tu- 

 mid, ovate, clothed with smaller, more abundant scales. Spike 

 terminal, simple, rather dense, of from 15 to about 20 flowers, 

 of a dull purplish brown, without any scent, and after awhile 

 turning entirely brown, dry and membranous. Bracteas soli- 

 tary under each flower, lanceolate, acute, rusty and downy. 

 Calyx-leaves deeply cloven. Upper lip oi the corolla large, 

 sometimes slightly cloven, often entire and rather pointed ; lower 

 in 3 acute, nearly equal, wavy, sometimes crenate lobes. Filam. 

 dilated and channelled, as well as perfectly smooth, in their 

 !ower half J glandular and downy at the summit. Anth. smooth, 

 brown. Germ, downy all over, as well as the style. Stigma of 

 2 large, distant, globular, yellow lobes. 



Haller's n. 295 appears, by his description of the smell, and by 

 Swiss specimens, to be the real O. major, garyophyllum olens of 

 Bauhin's Pinax 87 ; O. caryophyllacea, Sm. Tr. of Linn. Soc, 

 V. 4. 1G9 j though part of Haller's account applies rather to our 

 minor, especially with regard to its being a troublesome weed. 

 This O. caryophyllacea has been confounded by most former bo- 

 tanists with our major, as likewise with elatior. Its stamens are 

 hairy internally at the base. Style somewhat downy. 



2. O. elatior. Tall Broom-rape. 



Stem simple. Corolla fiinnel-sliaped; lower lip with acute, 

 nearly equal segments. Stamens downy. Style smooth.

In clover fields, thickets, and bushy hilly places, on a gravelly soil, 

 not uncommon ; but never on the roots of Broom or Furze. 

 Rev. Dr. Sutton. 



Perennial. July, August. 



Taller, and of a more yellowish hue than tlie former, v:\i\\ flowers 

 of a lighter purj)le, more wavy in their margins j their upj)er lip 

 lobed. They are commonly three times more numerous in the 

 spike than in that species, and of a smaller size. But their clear- 

 est and most essential diflerence, first remarked by Dr. Sutton, 

 consists in the sfamevs being downy in their lower half, within - 

 side, and smooth at the top ; while the gcrmcn and style are all 

 over perfectlv smooth. The stamen.^ proceed from a higher psirt 

 of the tube than in O. innjor.
