Class XX. Order I. 321 



tals five, spreading-, the two inner ones fringed. Lip of the nec- 

 tary somewhat exceeding the petals, divided into three segments? 

 which are wedge shaped, spreading like a fan, three parted, the 

 segments nearly equal, fringed, flat and not connivent. Upper 

 lip entire. Spur considerably longer than the germ. Meadows. 

 July. Perennial. 



I have ascertained that this is the O. fimbriata of Pursh by his 

 herbarium, and also of Wilklenow, fide Muhlenbergii. 



* ORCHIS GRA.NDIFLORA. Large flowering Orchis. 



O. labello dependcnte petalis duplo longiore y tripar- 

 tito, laciniis cuneiformibus, inciso-fimbriatis intermedia ; 

 maxima fimbriis conniventibus ; petalis later alibus den- 

 tato-Jimbriatis ; cornu adscendente, clavato, genuine 

 longiore ; foliis ovato-oblongis. 



Lip dependent, twice as long as the petals, three 

 parted, the divisions wedge shaped and fimbriate, the 

 middle one largest with connivent fimbriae; lateral pe- 

 tals fimbriate ; spur ascending, clavate, longer than 

 the germ ; leaves oval-oblong. 



This elegant plant grows to the height of two feet and up- 

 wards. Stem thick, angular, fistulous. Lower leaves oblong- 

 oval, obtuse ; upper ones and bractes lanceolate, acuminate. 

 Spike oval-oblong, many flowered. Petals all contiguous, pale pur- 

 ple, the three outer ones ovate, concave, entire ; the two inner 

 ones ovate, unguiculate, cut or fringed on the whole of their 

 sides, but scarcely so at the ends. Lip deeper purple, more 

 than twice the length of the petals, being sometimes nearly an 

 inch long, divided into three segments, the two lateral ones cu- 

 neiform, cut and fringed to the middle or farther, the middle 

 one twice as large, flabelliform, cut and fringed to the middle, 

 but not emarginate, the fimbriaj on each side the middle con- 

 verging in front of the lip. Upper lip with a notch between 

 the two anthers. Found at Lancaster, Leominster, Deerfield 

 &c. Abundant in Enfold, New Hampshire. 



This plant is perhaps the largest and most beautiful of 

 all the species of Orchis. The spike sometimes consists of a 

 few large flowers, but in favorable situations it is five or six
