MEMOIKS OF THE NEW YORK BOTAXIC.VL GARDEN 



coimate near the base, the five central ones conniving at the sum- 

 mit, the others gradually terminating in the margin, all con- 

 nected by slender nearly straight secondaries and by a fine retic- 

 ulum of veins. Only the floral leaves are present, the upper ones 

 successively reduced. Racemes several in the axils, mostly ses- 

 sile, unequal, the longer 1.5 dm. long, slender, rather densely 

 flowered, the bracts thin, lanceolate, acuminate, about 2 mm. 

 long, the bractlets similar or a little smaller, the branchlets 3- or 

 4-flowered. Flowers sessile, about 2 mm. long, the petals slightly 

 shorter than the sepals, ferruginous with lighter margins, much 

 thickened at the tomentose base, where the filaments are at- 

 tached. Stamens shorter than the perigone, the anthers small. 

 Small rudimentary 3-lobed ovary present.

ZlXGIBERACEAE 



Renealmia spectabilis 



Racliis, peduncles, etc., densely pilose with short, thick, taper- 

 ing hairs. Leaf (but one seen) 6 dm. long, 8 cm. broad, lanceo- 

 late, doubly acuminate, very acute at the summit, thickish, the 

 midrib very strong on both surfaces, the nerves innumerable and 

 very fine. Scape not seen. Rachis stout, angled, rather densely 

 flowered, the peduncles stout, 5 to 8 mm. long, mostly 1-flowered. 

 Bract about 2.5 cm. long and broader. Flower sliort-stipitate. 

 Ovary small, ellipsoid, densely sericeous-pilose. Calyx two- 

 thirds as long as the bract, the base connate about the corolla- 

 tube, the summit shortly and unequally 3-lobed. Corolla-tube 

 half the length of the calyx, turned almost horizontally, the lobes 

 about 2.5 cm. long, two lanceolate, the third ovate, all obtuse, 

 subhyaline and finely nerved. Labellum about as long as the 

 calyx, broadly obovate and obeordate. strongly complanate, 

 keeled, the keel strongly channeled within and extended at the 

 summit into a large, strongly incurved beak or hood. Lateral 

 staminodia very small, uncinately recurved. Filament opposite 

 the keel, rigid, erect, flattened and complanate, half the length 

 of the petals. Anther large. Style very slender, nearly as long 

 as the petals, the stigma 3-lobed. 



Rurrenabaque, 1,000 feet, Martin Cardenas, January 24. 1922 

 {no. 2039). "Bracts white, petals yellow with red Hues." 



Species strongly characterized by its long filament and 

 hooded labellum.
