MOUNT RORAIMA IN BRITISH GUIANA, 55 
Urricunaria CONCINNA, N. E. Brown, sp. n. (Plate 10, fips. 7-11.) Pusilla, glabra. 
Pedunculus uniflorus, $-1 poll. longus. Bracteæ et braeteolw lanceolate, obtuse. 
Sepala magna, cordato-ovata. Corolla erecta, labiis calyce paulo longioribus, 
glabris, labio superiore elliptico vel subrectangulare et apice obscure 3-crenato, 
labio inferiore elliptico vel subrectangulare undulato-crenato; calear labiis multo 
longius, erectum, acutum, prope apicem parcissime pilosulum. 
Leaves 2-4, all radical, 3-5 lin. long, lanceolate, elliptic or oblong-lanceolate, obtuse 
or subacute, tapering into a short petiole at the base, glabrous, erect. Peduncle 1-1 in. 
high, 1-flowered, slender, with two distant minute bracts, one near the middle, the 
other near the base, glabrous. Flowering-bract 2-1} lin. long, lanceolate, subobtuse, 
glabrous, not ciliate. Bracteoles resembling the flowering-bract, but shorter and 
narrower. Pedicel 2-3 lin. long, glabrous. Sepals 2, erect, large in proportion to the 
corolla, 21-33 lin. long, 2-21 lin. broad, cordate-ovate, obtuse, glabrous, not ciliate. 
Corolla erect, with the lips only slightly exceeding the sepals, and the spur about twice as 
long; upper lip 1ł-2 lin. long, and about the same in breadth, elliptic or subrectangular, 
obscurely 3-crenate at the apex, with recurved margins, glabrous ; lower lip about 231-27 
lin. long, elliptic or subrectangular, crenate and wavy at the apex, with the margins 
recurved, glabrous ; spur about 31-332 lin. long, erect, acute, with a few scattered hairs 
on the terminal half. Stamens glabrous. Ovary globose-ovoid, narrowed into a short 
stout style, glabrous; stigma with a narrow acute upper lip and a broad emarginate 
lower lip. Capsule about half as long as the sepals, ellipsoidal, obtuse, crowned with the 
short style and stigma. 
Kaieteur Savannah, Jenman, 1272; Mazaruni River, 300 ft., MeConnell & Quelch, 710; 
and without precise locality, Schomburgh, 181. 
The flowers of this diminutive species are stated by Messrs. McConnell and Quelch to 
be “ white with purple points." I have only seen one corolla, and am uncertain if my 
description of it is quite correet in all details, as it was very much flattened; but my 
drawings of it (figs. 8 & 9) represent its general appearance as nearly as the material 
would allow, although they may not be accurate. The affinity of U. concinna is with 
U. Campbelliana, Oliver, and U. montana, Jacq., although it is very much smaller than 
either of those species. 
UTRICULARIA NERVOsA, Weber ?, ex Benj. in Mart. Fl. Bras. x. p. 247. 
Upper slopes of Mount Roraima, MeConnell & Quelch, 3 a. 
Possibly a distinct species, but the material consists of one flowering stem only, which 
scarcely admits of proper dissection ; externally, however, it much resembles U. nervosa, 
which is a Brazilian species. 
UTRICULARIA sp. 
Arabapu River, McConnell & Quelch, 150 a. 
The specimen consists of leafy rhizomes without flowers, which were found entangled 
amongst the pitchers and false roots of Genlisea guianensis, N. E. Brown.
