110 ENGLISH BOTANY. 



much smaller than the other, and produced at the extremity of a long 

 slender fleshy stolon. Radical leaves commoidy 2, oblong or elliptical- 

 oblong, acute ; stem leaves none or 1, rarely 2, much smaller than the 

 radical leaves. Flowers in a rather dense elongated spike. Bracts 

 about as long as the ovary. Labellum saccate at the base, 3-cleft; 

 the middle lobe nearly twice as long as the lateral lobes ; all the 

 perianth segments pale greenish-yellow. 



In clialky and limestone pastures and on banks. Local ; occurring 

 in Hants, Sussex, Kent, Surrey, Essex (extinct ?), Berks, Bucks, 

 Oxford, Suffolk, Norfolk, Cambridge, Gloucester. It has also been 

 reported from Somerset, but this locality requires confirmation. I 

 have collected this plant only at Headley Lane and Corapton quarries, 

 Surrey, but have specimens also from Cheltenham, Gloucester; and 

 Halstead, Kent. 



England. Perennial. Summer. 



Rootknob at the base of the stem from the size of a pea to that of a 

 black currant, the newly-developed ones smaller. Stem 3 inches to 

 1 foot high. Radical leaves ^ to 3 inches long. Spike 1 to 4 inches 

 long, somewhat unilateral. Perianth horizontal or slightly drooping ; 

 the segments about -i inch long, the upper sepal oblong, the lateral 

 ones lanceolate. The petals narrower, rhombic-strapshaped. La- 

 bellum with the lateral lobes lanceolate, the middle lobe strap- 

 shaped. 



Musk Orchis.

GENUS F//.— OPHRYS. Linn. 



Perianth segments spreading ; labellum turned downwards, with- 

 out a spur. Anther wholly adnate to the column ; its two cells sub- 

 parallel, each containing a pollen-mass of which the elongate caudicule 

 is affixed to a gland, each of the two glands contained in a separate 

 pouch. Stigma without a rostellate process extending between the 

 bases of the anther-cells, or a plate in front of them. 



Herbs mth subglobular tubers, of -which the new one is sometimes 

 jiroduced at the extremity of a stolon. Flowers in a lax spike, few, 

 large, and often bearing a striking similarity to an insect, of which the 

 labellum represents the body, and the lateral sepals the wings. 



The name is from ocjipvg (ophrus), the eyebrow ; doubtless from the hairy humps 

 at the base of the lateral lobes of the labellum in some of the commoner species.
