about 5 mm. long ; lateral sepals oblong-lanceolate, obtuse : petals 

 broadly lanceolate ; blade of the lip ovate-hastate, distinctly 



auricled, and truncate at the base ; 

 spur filiform, two and a half times as 

 long as the lip. (Fig. 32.) 



I have not seen the type of Gym- 

 nadoiia longispica, which was de- 

 scribed from a fragmentary specimen 

 collected by Pratten, /. c, it consisted 

 only of the upper portion without any 

 leaves. Durand's species has been re- 

 garded as P. UnalascJiensis but this 

 cannot be so, for Gymnadenia long- 

 ispica was described as having a spur longer than the ovary, 

 which throws it out of P. UnalascJiensis. As the spike is described 

 as long and lax it must have been either P. cicgans, P. Icptopetala 

 or the species described here. As this is the only species with 

 broad bracts, the name G. longispka must belong here, unless 

 it is a species unknown to me. The only discrepancy is that the 

 spur is described as clavate, which is scarcely the case.
