Tribe in. ARETHUSEiE, MAIiAXIDE^XS, &c. Anther terminal (attached to 

 the apex of the column, or near it), and like a lid over the stigma, at length deciduous. 

 * Pollen in loose or powdery grains, forming 2 or 4 delicate masses. 



7. ARETHUSA. Lip bearded, its base adherent to the linear column. Pollen-masses 4 



8 POGONIA. Lip more or less crested, free from the club-s&aped column. Pollen-masses 2. 



9. CALOPOGON. Lip bearded, stalked, free: column winged at the a4)ex. Pollen-masses 2. 



* * Pollen in smooth and finally waxy masses. 



■*- Pollen-masses attached bj elastic stalks, or in No. 10 sessile. 



10. CALYPSO. Lip inflated and sac-like, notched at the apex and 2-pointed underneath the 



notch. Column winged and petal-like. Pollen-masses 4. Stem l-flowered.

gined. Pollen-masses 4. Raceme many-flowered. 

 12. BLETIA. Iap hooded, spurless. Column not margined. P(dlen-masses 8. 

 ■*- •*- Pollen-masses without any stalks or connecting tissue. 

 +* Plants green and with, leaves. Sepals spreading : lip flat and spurless. 

 13 MICROSTYLTS. Lip arrow-shaped or heart-shaped. Column minute, round. 



14. LXPARIS. Lip entire, dilated. Column elongated, margined at the apex. 



++ ++ Plants tawiQ' or purplish, leafless, or with a root-leaf only : sepals and petals conniving. 



15. CORALLORHTZA. Lip with a spur or projection at the base adherent to the ovary, Aa- 



ther-cells oblique. 



16. APLECTRUAL Lip spurless, free, raised on a claw. Anther rather lateral. 



U. Anthers two. 



Tribe IV. C YPRIPBDrE.^. The 2 anthers those of the lateral stamens : the third 

 or upper stamen (which is the one which bears the anther in the rest of the order) here 

 forming a petal-like sterile appendage to the column. 



17. CYPRIPBDIUM. Lip a large and inflated sac, somewhat slipper-form. 



1. ORCHIS, L. Orchis. 



Flower ringent ; the sepals and petals nearly equal, all of them, or all but tlie 

 2 lower sepals, converging upwards and arching over the column. Lip turned 

 downwards, coalescing with the base of the column, spurred at the base under- 

 neath. Anther-colls contiguous and parallel. Pollen cohering in numerous 

 coarse waxy grains, which arc collected on a cobweb-like elastic tissue into 2 

 lai-ge masses (one filling each anther-cell) borne on a slender stalk, the ba.se of 

 which is attached to the 2 glands of the stigma, contained in a Common little 

 poucli or hooded fold. Flowers showy, in a spike. COpxts. the ancient name.) 



I. O. S|>ecfcibilis, L. {Showy Orchis.) Root of thick fleshy fibres.
