110 ENGLISH BOTANY. 
much smaller than the other, and produced at the extremity of along 
slender fleshy stolon. Radical leaves commonly 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 chalky 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 Compton 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 } 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. 
French, Ophrys a un tubercule. German, Hinknollige Ragwurz. 
GENUS VU.—OPHRYS. Jinn. 
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 with subglobular tubers, of which the new one is sometimes 
produced 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 d¢pi¢ (ophrus), the eyebrow ; doubtless from the bairy humps 
at the base of the lateral lobes of the labellum in some of the commoner species.
