51 REPORT ON TWO BOTANICAL COLLECTIONS FROM 



Leafless at the time of flowering. Stems 1^—4 iu. high, filiform, glabrous, 1-2-flowered 

 and bearing 1-2 minute, peltately attached, very minutely ciliate scales. Bracts \ lin. 

 long, ovate, acute, peltately attached, minutely ciliate. Bracteoles slightly shorter than 

 the bracts, basifixed, oblong, acute, minutely ciliate. Pedicels 1-2 lin. long, glabrous. 

 Sepals about 1^ lin. long, the upper nearly 1 lin. broad, ovate, subacute, the lower 

 rather broader, emarginate at the apex, both deeply concave, strongly nerved, with a few 

 short hairs scattered along the nerves. Corolla ringent ; upper lip erect, 3-3^ lin. long. 

 j-1 lin. broad, subspathulate-oblong, obtuse, with recurved margins, minutely puberulous 

 inside at the base ; lower lip 4-5 lin. long, about 4 lin. broad, suborbicular, obtuse, 

 abruptly deflexed from the mouth of the spur, where it is minutely puberulous. Spur 

 4-|-5^ lin. long, nearly in a line with the upper lip, slightly curved forwards, gradually 

 tapering from the \h lin. broad base to the subacute apex, compressed. Filaments of 

 the stamens incurved, clavate, glabrous. Ovary ovoid, narrowed into a short style, 

 glabrous; stigma with a narrow acute upper lip and a broadly ovate obtuse lower lip. 



Arabapu River, McConnell §r Quelch, 127. 



Allied to U. cornuta, Michx., but smaller, more slender, and with a more reflexed lower 

 lip to the corolla. 



Utkicularia roraimensis, N. E. Brown, sp. n. (Plate 11, figs. 1-4.) Perennis. Poha 



radicalia, orbiculato-spathulata, 3-7 lin. longa. Caulcs simplices vel divisi, 11-3 



poll, longi, subfiliformi, 1-2-flori, 1-3-squamosi, glabri. Bracteae minutae, trifidse. 



Plores parvi, pedicellati. Sepala insequalia, glabra; sepalum superius ellipticum, 



obtusum, profunde concavum; inferius brevius, subquadratum, truncatum. Corollae 



labium posticum ovatum, obtusum, intra minute glandulosum ; labium anticum 



late subreniforme breviter 3-lobum, abrupte reflexum, minute glandulosum ; calcar 



late conicum, obtusum, minute glandulosum. 



Perennial. Leaves all radical, spathulate, glabrous; petiole 2-5 lin. long, slender; 



blade 1-2 lin. long, |-lf lin. broad, obovate or orbicular, obtuse, cuneate at the base. 



Stems 1-4 to a plant, simple or once branched, 1^-3 in. high, subfiliform, 1-2-flowered, 



glabrous, bearing 1-3 minute, oblong, obtuse, glabrous scales. Bracts minute, trifid, 



with the lateral teeth narrow and acute, and the middle tooth broadly rounded, glabrous, 



not ciliate. Pedicels l-2i lin. long, filiform, erect. Sepals unequal, thin, glabrous; 



the upper f-1 lin. long, elliptic or elliptic-ovate, obtuse, deeply concave, with about 4 



rather obscure veins ; the lower -J lin. long, and about the same in breadth, subquadrate, 



truncate or very slightly emarginate, 1-veined. Corolla small ; upper lip 1-1^ lin. long, 



|-f lin. broad, ovate, obtuse, concave, erect or ascending, minutely glandular within ; 



lower lip 1^-li lin. long, 2 lin. broad, subreniform, shortly 3-lobed, and more or less 



undulated, abruptly reflexed from the mouth of the spur on which it rests, minutely 



glandular on the lower part; spur H lin. long, 1} lin. broad at the mouth, broadly 



conical, obtuse, compressed, minutely glandular, directed at a right angle to the pedicel. 



Stamens with curved clavate filaments, glabrous. Ovary globose, abruptly contracted 



into a stout style, glabrous; stigma with a minute tooth-like upper lip and a large 



truncate lower lip.
