102 ENGLISH BOTANY. 



Eootknobs similar to those of tlic preceding species. Stem 6 inches 

 to 2 i'eet liigh or even more, more slender and commonly with a 

 greater difference in the size and shape of the upper and lower leaves, 

 the lower leaves of 0. maculata being more spreading, larger, broader, 

 and blunter than the upper ones, and almost always thickly spotted with 

 circular blotches of j)urpllsh-black. Spike 1 to 3 inches long, more 

 attenuated towards the apex and more acute, the bracts shorter iu 

 l)roportion, the flowers usually jjaler, the labellum much more deeply 

 3-loljed, and the lateral lobes usually much more crenate-denticulate ; 

 the time of flowering is later than that of 0. latifolia and about the 

 same time as that of 0. incarnata. 



Spotted Pabiiate Orchis. 



Frencb, Orcliis taclti. German, Gcjlccktcs KnahenkrauL 



GENUS ///.— G Y M N A D E N I A. li. Broivn. 



Perianth segments spreading, or the vipper 5 segments connivent; 

 labellum turned downwards, spurred at the base. Anther wholly 

 adnate to the column; its 2 cells converging at the base, and each 

 containing a pollen-mass, of which the caudicule is affixed to a gland, 

 the two glands not included iu a pouch. Stigma Avith a rostellate 

 l)rocess extending between the bases of the anther-cells. 



Herbs with palmated or pointed (rarely subglobular) rootknobs. 

 Habit similar to that of Orchis, but sometimes the flowers are more 

 or less secund. 



The derivation of tte name of tliis genus of plants is from the Greek words, yvniuc, 

 naked, and aci'ii; a gland, because the glands are not contained in a pouch.

Rootknobs 2, palmately cleft, compressed. Leaves oblong-strap- 

 shaped or strapshaped-lanceolate, acute. Flowers in a dense or rather 

 dense cylindrical tapering spike, not unilateral. Lateral sepals spread- 

 ing, the upper one and the lateral petals connivent ; labellum about as 

 broad as long, 3-lobed; the lobes all oblong-deltoid, obtuse, or the 

 lateral lobes subrhombic ; the middle lobe as broad as and a little 

 lon'i'cr than the lateral lobes ; the whole of the perianth segments
