Obs. Root a cNlindhc-obiong, and pendulous fleshy tu- 

 ber of a white colour. Stems often in clusters, cylindric 

 and succulent, about a span hig-h, often pubescent at the 

 base. Leaves 6 or 7, remote and very short, about half an 

 inch long-, amplexicaule, ovate and acute, 5 to 7-nerved, 

 pale green. Flowers 3 or 4, pale blueish-purple; pedun- 

 cles axillary and terminal, aboui the length of the germ, 

 after inflorescence pendulously recurved; petals linear- 

 lanceolate, equal in length, the 2 inner a little broader, 

 conniveiit, never expanding Lip before, about the length 

 of the petals, spathulate and cucullate, conspicuously un- 

 guiculate, the centre above the claw a little rough but not 

 crested; proper lip or middle lobe oval and entire. Ge- 

 nitaliferous column Imearly sp.athulate and unconnected, 

 not much shorter than the whole lip, flat, (not solid and 

 truncately clavate as in Pogonia) perpendicular, margin- 

 ated, the inner surface marked with an elliptic glandular 

 and secreting cicatrice. Anther 1 -celled, semicordate 

 and vertical, unguiculately articulated behind, colour a 

 brilliant and deep violel-purple. Pollen farinaceous, the 

 2? masses separated superficially by 2 internal lamellae. 

 (In the preceding genus there are both these lamellx and 

 a proper dissepiment.) Capsule cylindric-oblong. Hab. 

 Mostly parasitic round the roots of Beech trees, from N^ew 

 York to Kentucky, (very abundant near Cincinnati, on the 

 Ohio), I have also collected it near Savannah in Georgia. 

 —A second species fJlrethxisa gentianoiclesj appears to 

 exist in the island of Jamaica. Tiie whole habit and cha- 

 , racter is at variance with Pogo7iia It makes an artificial 

 approach towards Cymbidlum Inemale of Willdenow, 

 {Arethitsa spicata of Walter), but in this plant the anther 

 is deciduous.
