ORCHIDACEiE 



H. behrin- oblong : petals equalling the sepals, broadly lanceolate ; lip about 

 giana 5 j^j^ long; spur fully 10 mm. long, filiform. (Fig. 9.)

 sion, 143 (type in herb. Columbia Univ.)." Rydb. loc. cit. 



This is not closely related to any other American species. The 

 type specimens were labelled Habenaria gracilis Wats., with 

 which species it has little in common. 



Dr. Rydberg describes the flowers as purplish. I think that he 

 must be in error regarding this detail. From dried specimens — the 

 only ones which I have seen — the flowers appear to have been 

 greenish.

1 The specimens in hb. 6 are not uniform. On the upper half of the sheet are three plants 

 of H. behringiana which, in a note, J. Macoun has attributed to Grebnitzky, who collected 

 them on Bering Island. On the lower half of the sheet are two specimens of H. viridis 

 var. bracteata. The label which originally accompanied these five specimens tells that they 

 were found in boggy spots, Attu Island, by J. M. Macoun in August, 1891. As Macoun's 

 note refers directly to the specimens of H. behringiana it is impossible to state definitively 

 that they came from North America. Presumably the specimens of H. viridis var. bracteata 

 were collected on Attu Island.
