Variat spicis terminalibus (1-2) apice masculis. 
This species is allied to G. tentaculata and its allies. Steudel 
describes his 0. feminea :—“ Spica infima pedunculo e vagina 
longissime exserto, cum spica accessoria minore, summa (vel 2-3) 
apice brevissime mascula.” The specimens I have seen of Tech¬ 
ier vary in these respects. That in the Herb. Mus. Paris has the 
terminal spike nearly entirely male, with only two female florets 
at base. I have no hesitation in referring his plant to G. acutata. 
I have figured Tab. CCCCXLYI. the specimen of Spruce. The 
name he had given refers to the delicate tessellated or chequered 
texture of the perigynium, common to many species.' Tab. 
CCCCXLVII. is the specimen from Ecuador, in Herb. Hooker.
