56 REPOET ON TWO BOTANICAL COLLECTIONS EEOM 



Genlisea guianensis, N. E. Brown, in Hooker, Icones Plant, t. 2629. 



Arabapu River, McConnell Sf Quelch, 150. 



This is the largest species of this genus at present discovered, and more nearly 

 resembles O. 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 amouut of nitrogen to the 

 plants by the absorption of the decomposed remains of the minute animaleula? they 

 capture. The utricles have a very remarkable structure, which will be found well 

 described and illustrated in Darwin's ' Insectivorous Plants,' p. 146, and Goebel's 

 ' Pflanzenbiologische Schilderungen,' ii. p. 121, t. 15-16. 



Genlisea roraimensis, N. E. Brown, sp. n. (Plate 11, figs. 5-12.) Eolia obovato" 

 vel rotundato-spathulata, crassiuscula vel subcoriacea, glabra. Utriculi hi formes, 

 alter apice bilobus, alter apice acutus, minute 1-porosi. Caulis 1^-3 poll, longus, 

 3-6-squamosus, minute glanduloso-hirtellus, 1-4-florus. Bracteae et bracteola; 

 minutae, lanceolatae, acuta?. Pedicelli minute gland uloso-hirtelli. Calyx 5-lobus, 

 minute pubescens. Corolla parva, lutea, labio superiore late ovato vel clliptico- 

 ovato obtuso concavo glabro, labio inferiore reflexo obtuse trilobo glabro, calcari 

 late conico obtusissimo minute glanduloso-birtello. 

 A perennial with a very short branching rhizome densely covered with leaves. Leaves 

 rosulate, 3-5 lift, long, J-f lin. broad, obovate- or orbicular-spathulate, rather thick or 

 subcoriaceous, glabrous. Utricles 2^-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, 1^-3 in. high, J— J lin. 

 thick, 1-4-flowered, minutely and rather sparsely glandular-hairy, bearing 3-6 lanceolate, 

 acute, basifixed, glabrous scales about f lin. long. Bracts and bracteoles subequal, 

 basifixed, about f lin. long, lanceolate, acute, sparsely pubescent and ciliate. Pedicels 

 1-2 lin. long, glandular-pubescent. Calyx 5-lobed almost to the base ; lobes f-1 

 lin. long, oblong-lanceolate, acute, thinly pubescent and slightly ciliate. Corolla 

 small, yellow; upper lip \h 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 

 3dobed, glabrous ; spur \\ lin. long, 1\ 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 oblique. 

 Capsule globose, about 1 lin. diara., minutely and sparsely haiiy.
