if not always, parasitical; their whole surface minutely 

 downy, or mealy, brownish, dull purple, or red. Fl. 

 more coloured, but withering, and turning brown, before 

 the corolla falls. The roots are small, fibrous, generally 

 attached to those of Broom, Furze, Clover, or other pa- 

 pilionaceous plants ; some of them to Hemp.

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

 Broom or Furze. 



Perennial. June, July. 



Root 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 a while 

 turnino- entirely brown, dry and membranous. Bracteas soli- 

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

 Calyx-leaves deeply cloven. Upper lip of 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 

 lower half ; 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 Finax 87 ; O. caryophyllacea, Sm. Tr. of Linn. Soc. 

 V. 4. 169 5 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,
