56 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
GENLISEA GUIANENSIS, N. E. Brown, in Hooker, Icones Plant. t. 2629. 
Arabapu River, McConnell & Quelch, 150. 
This is the largest species of this genus at present discovered, and more nearly 
resembles G. africana, Oliver, (a native of Angola), than any other with which I am 
acquainted. The members of the genus Genlisea appear to be quite destitute of true 
roots, their place being supplied by modified leaves, which descend into the soil or water. 
Some of these modified leaves terminate in the curious tubular two-lobed utricles 
characteristic of the genus, others being quite simple and root-like ; probably all fulfil 
the functions of roots, and the utricles supply an additional amount of nitrogen to the 
plants by the absorption of the decomposed remains of the minute animalcule they 
capture. The utrieles have a very remarkable structure, which will be found well 
described and illustrated in Darwin’s *Insectivorous Plants,’ p. 446, and Goebel’s 
‘ Pflanzenbiologische Schilderungen, ii. p. 121, t. 15-16. 
GENLISEA RORAIMENSIS, N. E. Brown, sp. n. (Plate 11, figs. 5-12.) Folia obovato- 
vel rotundato-spathulata, crassiuscula vel subcoriacea, glabra. Utriculi biformes, 
alter apice bilobus, alter apice acutus, minute l-porosi. Caulis 1}-3 poll. longus, 
3-6-squamosus, minute glanduloso-hirtellus, 1-4-florus. Bracteze et bracteole 
minute, laneeolatze, acute. Pedicelli minute glanduloso-hirtelli. Calyx 5-lobus, . 
minute pubescens. Corolla parva, lutea, labio superiore late ovato vel elliptico- 
ovato obtuso coneavo glabro, labio inferiore reflexo obtuse trilobo glabro, calcari 
late conico obtusissimo minute glanduloso-hirtello. 
A perennial with a very short branching rhizome densely covered with leaves. Leaves 
rosulate, 3-5 lin. long, 1-2 lin. broad, obovate- or orbicular-spathulate, rather thick or 
subcoriaceous, glabrous. Utricles 23-5 lin. long, of two forms, both tubular and ovoid- 
inflated at the base and descending into the soil among the roots, one (the perfect form) 
dividing at the mouth into two long twisted lobes, the other (a transition form) acute, 
with a very minute orifice at the apex and entirely without lobes; a third and imperfect 
form is sometimes present standing erect among the leaves in which the terminal lobes 
are very short and scarcely or not at all twisted. Stem simple, 13-3 in. high, 4—4 lin. 
thick, 1-4-flowered, minutely and rather sparsely glandular-hairy, bearing 3-6 lanceolate» 
acute, basifixed, glabrous scales about $ lin. long. Bracts and bracteoles subequal, 
basifixed, about $ lin. long, lanceolate, acute, sparsely pubescent and ciliate. Pedicels 
1-2 lin. long, glandular-pubescent. Calyx 5-lobed almost to the base; lobes 3-1 
lin. long, oblong-lanceolate, acute, thinly pubescent and slightly ciliate. Corolla 
small, yellow; upper lip 13 lin. long, 1 lin. broad, broadly ovate or elliptic-ovate, obtuse, 
concave, glabrous; lower lip 2 lin. long and as much in breadth, reflexed, obtusely 
3-lobed, glabrous; spur 1j lin. long, 14 lin. broad at the mouth, stout, conical, very 
obtuse, compressed, slightly and minutely glandular-hairy, and darker in colour than the 
rest of the flower. Stamens glabrous; filaments curved, clavate; anthers deep blue. 
Ovary globose, thinly covered with very minute hairs; style short; stigma aan Ae 
Capsule globose, about 1 lin. diam., minutely and sparsely hairy. 
Summit of Mount Roraima, 8600 feet, growing in a somewhat sandy boggy soil,
