Originally discovered by Bridges in Bolivia,* from whose herbarium 



specimen it was named and described by Dr. Lindley. It was 



introduced by us in 1863 through Pearce, and flowered for the first 



time in this country, at our Chelsea Nursery, in May of the 



following year. The specific name, from car ex, " a sedge," refers to 



the sedge-like leaves, 

 i 



O. caudatum. 



Leaves ligulate, acute, 10 — 15 inches long. Scapes robust, pubescent, 

 pale green, 15 — 20 inches long, 1- — 4 but usually 3 flowered ; pedicels 

 with ovary 6 inches long, with a compressed sheathing pale green bract 

 at the base of each. Flowers the largest in the section ; upper sepal 

 6 — 7 inches long, lanceolate, acuminate, pubescent on the back, pale 

 yellow or whitish with longitudinal yellow-green veins in front; lower 

 sepal similar but broader, and concave at the base ; petals linear, 

 ribbon-like, pendulous, 18 — 25 or more inches long,t dull brownish 

 crimson, except at the base where they are yellowish ; lip calceiform, 

 prominent, 2 — 2J inches long, brownish green passing into bronzy green 

 around the aperture, the veins and reticulations dark green, pale yellow- 

 green beneath, the infolded lobes meeting at their edges, ivory-white, 

 spotted with purple inside the yellow-brown border around the aperture. 

 Staminode triangulate, auriculate, yellowish, the auricles fringed with 

 brown-purple hairs.

var. — Lindenii. 



Lip not saccate but ribbon-like and pendulous like the petals, to 

 which it conforms, except in being broader and concave at the base. 



* At a place called Tampoto, a name we do not find on any map to which we have access. 

 Pearco gave no locality. 



t When the flower first expands, the petals are 3 — 4 inches long ; they continue growing 

 for about ten days, in which time they usually attain their full length. From the seconl to 

 the seventh day they have been observed to increase in length as much as 2 inches each day. 

 nstance3 have been noticed in which the total length of the petals exceeded 30 inches.
