 scape a span or two long, 2— 4-flowered : corolla over half inch broad ; lower lip 3-lobed, its 

 lateral lobes saccate and the central larger, about twice the length of the conoidal com- 

 pressed spur: seeds globular, chafiiy -muricate. — Car. 64 ■! (doubtful, because the flowers 

 are said to be small) ; Pursh, Fl. i. 15; LeConte, 1. c. ; A.DC. 1. e. 5. U. saccata. Ell. Sk. 

 i. 21, said to have been so named by LeConte. — Ponds, Maine and N. Penn. to Florida,

§ 3. Scape leafless and solitary, the base rooting in the mud or bog, usually 

 rising from or producing filiform and root-like creeping shoots, which bear slender 

 subulate-gramineous (occasionally septate) simple leaves, or branches which take 

 the place of leaves, to the lower part of which, as also to the colorless shoots, 

 bladders are sparingly attached, usually fugacious or unnoticed, so that the flower- 

 ing plant appears to be a leafless and naked scape only. 



* Flower violet-purple, solitary and transverse on the summit of the scape : leaves of the rooting 

 slioots sometimes furnished with a few capillary lobes. 



' U. resupindta, B. D. Greene. Scape filiform, a span high : corolla 4 or 5 lines long, 

 deeply 2-parted ; lips almost entire ; upper narrowly spatulate ; lower dilated and with a 

 small palate : spur oblong-conical, very obtuse, ascending, shorter than and remote from 

 the corolla, which appears as if resupinate : leaves an inch or so long, attenuate. — Hitch- 

 cock, Cat. PI. Mass.; Bigel. Bost. ed. 3, 10; A.DC. Prodr. 1. c. 11; Gray, Man. ed. 1,

# * Flowers mostly yellow, solitary or several : spur descending: leaves entire, terete : these and

U. subuldta, L. Filiform radical shoots and leaves rather copious, but commonly evan- 

 escent : scape filiform, an inch to a span high, 1-9-flowered ; the raceme becoming zigzag : 

 pedicMs slender : corolla 2 or 3 lines broad ; lower lip plane or with margins recurved, 

 equally 3-lobed, much larger than the ovate upper one, nearly equalled by the oblong 

 acutish appressed spur. — Spec. i. 18 (Gronov. Virg., ex herb. Clayt.) ; Pursh, 1. c. ; A. DC.
