1. A. blllbosa, L. Flower single, erect, with an entire lip recurved at the 

 apex and bearded-crested down the face. Bogs, Virginia to Maine, N. Wis- 

 consin, and northward : rather scarce or local. May. Flower 1' - 2' long, very 

 handsome, bright rose-purple ; very rarely a pair of flowers. 



7. POGO3STIA, Juss. POGONIA. 



Flower irregular, the sepals and petals separate. Lip crested or 3-lobed. 

 Column free, elongated, club-shaped, wingless. Anther terminal and lid-like, 

 stalked : pollen-masses 2 (one in each cell), powdery-granular. (iTooyow'as, 

 bearded, from the lip of some of the original species.) 



1 . Sepals and petals nearly equal and alike, pale rose-color, sometimes white. 



1. P. ophioglossoides, Nutt. Root of thick fibres ; stem (6' -9' high) 

 bearing a single oval or lance-oblong leaf near the middle and a smaller one or 

 bract near the terminal flower, rarely one or two others with a flower in their 

 axil ; lip spatulate below, appressed to the column, beard-crested and fringed. 

 In bogs. June, July. Flower 1' long, sweet-scented. An interesting mon- 

 ster of this, with two additional lips, and some other petaloid parts, was found in 

 Herkimer Co., New York, by J. A. Paine. 



2. P. p^ndula, Lindl. Stem (3' -8' high) from oblong tubers, bearing 3 

 to 7 alternate ovate-clasping very small (3" -6") leaves, the upper 1-4 with 

 drooping flowers in their axils on slender pedicels ; lip spatulate, somewhat 3- 

 lobed, roughish or crisped above, crestless. (Triphora pendula, Nutt.) Damp 

 woods : rather scarce. Aug. Perianth ^' long, narrow^ 



2. Sepals linear, dingy or brownish, lonyer and much narrower than the erect or con- 

 nicent petals : lip 3-lobed at the apex, crested down the middle, beardless : /lowers 

 solitary (or rarely a pair), terminal: root a cluster of fibres. 



3. P. divaricata, R. Br. Stem ( 1 - 2 high) bearing a lanceolate leaf in the 

 middle, and a leafy bract next the flower, which is recurved on the ovary ; but the 

 sepals ascending or diverging, spatulate-linear, longer than the lanceolate-spat- 

 ulate pointed and flesh-colored petals, these about I'-l^' long. Wet pine- 

 barrens, Quaker Bridge, New Jersey ( W. H. Leggett), Virginia, and southward. 

 June, July. 



4. P. verticillta, Nutt. Stem (6' - 12' high), naked, except some small 

 scales at the base, and a whorl of mostly 5 obovate or obovate-oblong sessile leaves at 

 the summit ; flower dusky purplish, on a peduncle longer thdn the ovary and pod ; 

 sepals more than twice the length of the petals, narrowly linear, spreading from a 

 mostly erect base (l^'-2' long) ; lip with a narrow crest down the middle. 

 Low woods : rather rare, especially eastward. May, June. Glaucous when 

 young. Stalk of pod about 1^' long, more than half the length of the leaves. 



5. P. afiinis, C. F. Austin, n. sp. Somewhat smaller than the preceding ; 

 leaves paler and rather narrower; flowers (not rarely in pairs) yellowish or 

 greenish; peduncle much shorter than the ovary and pod; sepals not twice the length 

 of the petals, tapering to the base; lip crested over the whole face and on the 

 middle of the lobes. With the last, which it nearly resembles, but is much 

 rarer. Southern New York and Northern New Jersey, C. F. Austin ; and 

 Connecticut, near New Haven, Edward Dana.
