ORCHIDACEiE 



"Hab. in ora occidentali Americce septentrionalis, Menzies; H. saccata 

 Observatory inlet. Herb. Hooker, {hah. s. sp. comm. eel. Menzies.) 



"Caules debilis, l|^-2-pedales. Folia 3-poll. longa, parum acu- 

 minata, nullo modo acuta." Lindl. loc. cit. 



I have studied Lindley's type specimens of Platanthera gra- 

 cilis and P. stricta in conjunction with numerous specimens, 

 selected for comparison, from my own herbarium. P. gracilis is 

 a slender plant with linear, obtuse or acute leaves. P. stricta, on 

 the other hand, is a stout plant with rather broad leaves; ovate- 

 lanceolate according to Lindley's description. I have found that 

 the only characters which Lindley employed to separate these 

 species are inconstant, and consequently negligible. Aside from 

 these characters used by Lindley there are no others that I have 

 been able to discover which may be used to separate P. gracilis 

 from P. stricta. (Plate 61.)
