508 GYNANDRIA MQNANDRIA. 



ClLIATE HaBEXARIA. 



Root perennial, a fascicle of coarse fleshy fibres, and occasionally of tubcra. 

 Stem I to 2 feet high, angular, smooth, leafy, sheathed at base. Leaves 3 to 6 

 inches long, and 3 fourths of an inch to 2 inches wide, lanceolate, acute, or acu- 

 minate, nerved, smooth, sessile and sheathing,— usually 2 or 3 larger ones below, 

 and several small bract-like ones above. Flowers rather large, deep orange-yel- 

 low, spreading, in a thick oblong terminal spike 2 to 3 or 4 Inches long; bracts 

 lanceolate, acuminate, nerved, shorter tliau the ovary. Outer segments of the 

 perianth orbicular-ovate, or obovate, the lateral ones deflected,— the inner lateral 

 ones linear or ligulate, lacerately fringed at apex ; lip lance-oblong, or elliptic- 

 ovate, nearly twice as long as the perianth-segments, plnnatifid-lacinlate, or 

 friuged all round the margin, the segments capillary, and often 2 or 3-cleft; spur 

 filiform, longer than the sessile ovary. 

 Hub. Swamps ill the Mica-slate : not common. Fl. July— August. Fr. Sept. 



Obs. This handsome species is often abundant in the Mica-slate swamps; but 

 is rare elsewhere. 



5. H. fissa, Br. Lip 3-parted ; lobes cuncatc, dentate, the middle 

 one bifid ; spur longer than the ovary, filiform-clavate, curved. JBeck r

Orchis fissa. Will d. Muhl. Pursh, &c. 



Cleft Habexaria. 



Root perennial. Stem 2 to 3 or 4 feet high, fislular, angular, smooth, leafy. 

 Leaves 3 to 5 inches long, sessile,— the lower ones oblong-ovate, rather obtuse, the 

 upper ones smaller, bract-like, lanceolate, acute and acuminate. Flowers largo- 

 purple, in an oblong terminal spike 3 to 5 inches long ; bracts lanceolate, acumin- 

 ate, shorter than the ovary. Outer segments of the perianth obliquely orbicular- 

 orate, or obovate, the lateral ones deflected, the inner lateral ones obovatc-cune- 

 ate, entire ; lip twice as long as the perianth-segments, 3-parted, the lobes spread- 

 ing, cuneate, irregularly incised-dentate at apex (sometimes nearly entire, or ob- 

 soletoly dentate?), the intermediate lobe rather the largest, cleft in the middle to 

 one fourth or one third of its length ; spur somewhat clavate, longer than the-, 

 sessile ovary. 

 Hab. Moist grounds ; near Pigeon Creek : rare. Fl. August. Fr. 



Obs. Collected at the above locality., on the North side of the County, near the 

 Schuylkill, the present season (1S36), by Mr. Joseph Kinkhart. It is a rara 

 species, here ; and my specimens are rather imperfect. 



6. H. fimbriata, Br. Lip 3-parted, spreading, scarcely longer than, 

 the perianth-segments; lobes nearly equal, fan-shaped, fimbriate; spur 

 longer than the ovary, filiform-clavate, curved. Beck, Bot. p* 349. 

 Orchis fimbriata. Jit. and the Authors, generally, here cited. 



FsUkgeh Habexarta. 



Root perennial, a fascicle of coarse fleshy fibres, and sometimes tapering tubers. 

 Stem 2 to 3 feet high, stout, fistular, angular, smooth, leafy, sheathed at base. 

 Leaves 3 to 6 inches long, and 1 to 2 inches wide, elliptic-lanceolate, acute, nerved, 

 smooth, sessile and sheathing,— usually 3 or 4 larger ones below, and sevcrar 

 small bract-like ones above. Flowers rather large, bright purple, in a somewhat 

 compact cylindric-oblong terminal spike 3 to 5 or 6 inches in length, and an inch 

 to an inch and half in diameter ; 6rac/s linear-lanceolate, shorter than the flowers, 

 Outar segments of the perianth ovate, entire, the inner lateral segments cuneate^
