Utricular! a concinna, N. E. Brown, sp. q. (Plate 10, dgs. 7-11.) Pasilla, glabra. 

 Pedunculus uniflorus, f-1 poll, longus. Bracteae ft bracteolse lanceolata-, obtusse. 

 Sepala magna, cordato-ovata. Corolla erecta, labiis calyce paulo longioribus, 

 glabris, labio superiore elliptico vel subrectangulare el apice obscure 3-crenato, 



lal)io infcriore elliptico vel subrectangulare andulato-crenato ; calcar labiis multo 

 longius, erectum, acutum, prope apicem parcissime pilosulum. 



Leaves 2-4, all radical, :> 5 lin. long, lanceolate, elliptic or oblong-lanceolate, obtuse 

 or subacute, tapering into a short petiole at the base, glabrous, erect. Peduncle £-3 in. 

 high, 1-flowered, slender, with two distant minute bracts, one near the middle, the 

 other near the base, glabrous. Flowering-bract §— 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, 2h-Xl lin. long, 2-2^ 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 1^-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 2 ' -2 v 

 lin. long, elliptic or subrectangular, crenate and wavy at the apex, with the margins 

 recurved, glabrous ; spur about 3J-3| 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.

 and without precise locality, Schomburgk, 131. 



The flowers of this diminutive species are stated by Messrs. McConnell and Quelch to 

 be "white with purple points." 1 have only seen one corolla, and am uncertain if my 

 description of it is quite correct in all details, as it was very much flattened; but my 

 drawings of it (tigs. S & 0) represent its general appearance as nearly as the material 

 would allow, although they may not be accurate. The affinity of 77. concinna is with 

 77. Campbelliana, Oliver, and 77. montana, Jacq., although it is very much smaller than 

 either of those species. 



Utricularia nervosa, Weber ?, ex Benj. in Mart. PI. Bras. x. p. 217. 



Upper slopes of Mount Roraima, McConnell A' Quelch, 3«. 



Possibly a distinct species, but the material consists of one flowering stem only, which 

 scarcely admits of proper dissection ; externally, however, it much resembles 77. nervosa} 

 which is a Brazilian species. 



Utricularia sp. 



Arabapu River, McConnell 8f (Quelch, 150^. 



The specimen consists of leafy rhizomes without flowers, which were found entangled 

 amongst the pitchers and false roots of Genlisea guicmensis, X. E. Brown.
