629 



Fischer in Kamtchatka. The t\'pe is in Lindley's herbarium and 

 a cotype in Torre>-'s. The Unalaska specimen also collected by 

 Fischer, I cannot distinguish from the Asiatic. 



Type : "In KamtcJiatka, Fischer {hab. s. sp. couim. ccl. Prcs- 



cott)r 



Asia : Kamtchatka, Fischer, ex. herb. Liudley. 



Alaska : Unalaschca, Fischer. 



§ Arizoxicae : Rather stout, 5-7 dm. high : spike long and lax : 

 flowers light greenish ; lip linear, not at all dilated at the base ; 

 spur filiform, almost twice as long as the lip ; connective narrow. 



20. Limnorchis Arizonica sp. no v. 



Stem tall, leafy : lower leaves oblong, about 5 cm. long, obtuse, 

 the middle and upper ones linear, the former 2-3 dm. long, 2-3 

 cm. wide : spike slender, lax, many-flowered 

 1.5-3 cm. long; bracts linear-lanceolate, the 

 lower slightly longer than the flowers : these 

 12-15 mm. long, greenish or purplish : upper 

 sepal broadly ovate, 3-4 mm. long ; lateral 

 ones ovate-lanceolate : petals lanceolate, acute, 

 slightly shorter than the upper sepal, 4-5 

 mm. long. (Fig. 21.) 



This species resembles somewhat both L. 

 stricta and L. sparsiflora. From the former 

 it is easily distinguished by the long slender spur and from the 

 latter by the many-flowered spikes, smaller flowers and narrow 

 connective. It grows in rich canons of Arizona.
