Ponera longipetala is the only Ponera which is normally 
branched. We have seen a collection of P. striata (Lun- 
dell 1102 from Mexico in Herb. Ames Nos. 4369, 38055 
with a branched stem which was due to an injury. 
Mexico: Guerrero, pine-oak forest near Jaleaca, epiphyte, 2000 
meters alt., April 9, 1936, Otto Nagel & Juan G. 3252 (Tyrer in Herb. 
Ames No, 52256).

Reichenbach stated that this species is allied to and 
resembles in habit P. striata. The flowers, which were 
said to be borne solitary or in fascicles along the stem, 
have a lip which was described as: **.. . rhombeo ligulato 
apice bilobulo.’’ Reichenbach’s illustration (Xen. Orch. 
1 (1854) t. 19, fig. 12) shows a lip which approaches be- 
ing rhombic-lanceolate with a tapering apical portion. 
In keying out the species of Ponera in Walp. Ann. 6 
(1862) 450-454, Reichenbach placed P. macroglossa in 
the “‘Ebulbes distichifoliae’’ section. However, in spite 
of this, Schlechter later transferred this species to the 
genus Scaphyglottis, which, if this transfer were correct, 
would place the species in Reichenbach’s ‘‘Pseudobul- 
bosae’’ section. 
It is reasonable to suppose that if it were possible to 
examine the type of P. macroglossa, it might prove to 
be a variety of P. striata. However, for the time being, 
it seems best to recognize P. macroglossa with some 
doubt as to its true status. It has been collected only in 
Guatemala.
