ORCHIDACEtE 



produced opposite the lowermost leaves, one at each node ; inter- 

 nodes approximately 2-3 cm. long. Leaves at first crowded, the 

 sheaths of the petioles entirely concealing the upper part of 

 the stem, apparently variegated with oblique cross veins of a 

 deep green when fresh ; where the stem is revealed it appears to 

 have been suffused with purple when in life. Racemes slender, the 

 period of anthesis of long duration as is shown in the type in 

 which the lowermost flowers are expanded while the buds of the 

 upper flowers are crowded in a pyramidal, dense cluster 2.5-3 cm. 

 long. Rachis densely glandular pubescent. Peduncle about 3 cm. 

 long between the uppermost foliaceous bract and the lowermost 

 flower, densely glandular, brownish pubescent. Sepals with a few 

 extraordinarily long glandular hairs scattered over the outer sur- 

 face and with a tuft of hairs near the tip, the longest ones .5 mm. 

 in length, margins smooth. Petals slightly dilated above the mid- 

 dle, smooth, lightly adherent to the upper sepal. Labellum fleshy, 

 densely papillose on the upper third, the dilated bilobed or cres- 

 cent-shaped terminal portion being papillose on both the upper 

 and lower surfaces; spur cylindrical, about equally thick from the 

 base to the more or less abruptly rounded tip, on the anterior 

 wall within there are four linear calli, — in parallel pairs, — alter- 

 nating with the three main nerves, two (the outer ones) situated 

 just below the middle of the spur, two (the inner ones) with their 

 free tips almost reaching the tip of the spur. Ovary 5 mm. long, 

 fusiform-cylindrical, densely glandular hairy. 



The terminal lobes of the lip suggest very strongly the Peru- 

 vian Erythrodes bifalcis (Lindl.) Ames which has a much more 

 slender, spur-like sac. The type, according to notes in my her- 

 barium, is very similar in habit to Spruce 4464 and 4870 pre- 

 served at Kew, specimens referable to^. repens (Poepp. & Endl.) 



Ames. In the form of the labellum, in the rostellum and elon-
