LENTIBULARIEjE. 391 



Grenada, Trinidad !, Pd., Cr. ; epiphytical on mountain-trees, among mosses, at 2800' alt. ; 

 [French islands; Darien, Venezuela!, Guiana !, New Granada !, Peru!]. 



§ 2. Leaves entire or disappearing ; root-fibres thin, often furnished with little bladders. 

 — Terrestrial scapes (Oligocysta, A. DC). 



2. XJ. amethystina, St. Hit. Scape filiform : scales minute, distant, exauriculate at 

 the base ; leaves few, rosular, small, obovate or roundish, petioled ; raceme lax, few-flowered : 

 pedicels capillary, distant, spreading-erect : bracts 2-3-fid ; calyx-segments roundish, en- 

 tire ; corolla small, variegated : upper lip entire, inferior slightly 3-lobed or subentire, ex- 

 ceeded by the conical-cylindrical, bluntish, or pointed spur. — Marl. Fl. Bras. 9. t. 21. f. 1, 

 t. 22. f. 6: larger-flowered, and with larger ovate-roundish leaves. — U. modesta, A. DC! 

 (in PI. Pcepp.). U. globularifolia, var. minor, Benjam. ! (in PI. Kegel.) : I see no specific 

 difference in Salzmann's original U. amethystina. Several other forms are probably likewise 

 identical, e.g. U. obovata, Miq., U. spathulata, Splitg., U. versicolor, Benjam. — Root-fibres 

 at length stoloniferous : bladders rare, minutely globose, subsessile ; stem 4"-12" high , 

 leaves 2"'-3'", pedicels 6'", inferior lip 1"', spur l£'"-2"' long ; flowers blue with yellow, or 

 whitish-blue. — Hab. Dominica!, Imr. ; [Venezuela, Guiana!, Brazil!]. 



3. XJ. pnsilla, V. Scape capillary : scales and bracts auricled at the base, minute, 

 distant ; leaves few, rosular, very small, obovate or oval, shortly petioled, often none ; ra- 

 ceme few(-l)-flowered, flexuose : pedicels capillary, spreading-erect : bracts undivided, 

 single ; calyx-segments elliptical-roundish ; corolla small, " yellow :" upper lip subentire, 

 inferior 3-lobed, half as long as the conical-subulate ascending spur. — U, leptantha, Benj. 

 ex descr. — Root fibrous : bladders minute, stipitate ; stem 1"-3'V high , leaves l"'-2'", pe- 

 dicels 2'", inferior lip 1'", spur 2'" long. — Hab. Jamaica !, Al., in muddy places, S. Anus ; 

 Trinidad !, Cr. ; [Guiana, Brazil]. 



4. XJ. subulata, L. Scape capillary : scales and bracts auricled at the base, minute, 

 distant ; leaves very small, spathulate-linear, usually none ; raceme few-flowered, flexuose : 

 pedicels capillary, spreading : bracts undivided, single ; calyx-segments elliptical ; corolla 

 small, "yellow:" upper lip entire, inferior slightly 3-lobed, nearly as long as or longer than 

 the conical-subulate, bluntish spur. — U. nervosa, Benjam. in PL Kegel. ! ; a low form, with 

 more approximate pedicels : the same was collected by Crueger and by Spruce : leaves and 

 bladders on the root-fibres exist in Kegel's plant : the figure of U. nervosa in Mart. Fl. Bras. 

 has larger flowers. — Root fibrous : bladders minute, rare, often wanting ; stem 8"-l" high ; 

 pedicels 2"'-3'", spur 2'" long.— Trinidad !, Cr. ; [United States ! to Brazil !]. 



5. XJ. angustifolia, Benjam. ! Scape slender, filiform, somewhat rigid, flexuose : 

 scales and bracts exauriculate, minute, very distant ; leaves long, grass-like, linear, taper- 

 ing towards the petiole, disappearing ; raceme elongated, 2-6-flowered ; pedicels very dis- 

 tant, capillary, spreading : bracts cut into setaceous segments ; calyx-segments ovate-round- 

 ish ; corolla small : upper lip entire, inferior subentire, nearly as long as the conical-subu- 

 late, subincurved, pointed spur. — Root fibrous : bladders " none ;" stems V-2' high, often 

 several from the same root ; leaves subsolitary, 4"-7"(-l") long, 1 j"' broad ; pedicels 6"'-2'", 

 spur 3"' long; corolla pale-blue (Or.), yellow (Kegel). — Hab. Trinidad!, Pd., Cr., in 

 moist, sandy savannahs, Arima, Omeara, Aripo ; [Guiana !]. 



§ 3. Leaves capillary-dissected, swimming by means of the bladders; roots none. — 

 Peduncles (scapes) emersed (Lentibularia, A. DC). 



6 XJ. obtusa, Sw. Leaves whorled along submersed interwoven stems, and at the base 

 of the scapes : bladders obliquely subglobose, scattered on their capillary segments ; scape 

 filiform devoid of scales; raceme lax, few-flowered: bracts sheathing, truncate-roundish, 

 single exauriculate : pedicels distant, spreading, as long as the internodes ; calyx-segments 

 roundish • corolla small, yellow . lips entire or inferior subentire, nearly as long or little 

 PTrpededbv the subulate, bluntish, incurved spur.— Scape 6"-2", pedicels 4"'-6'", spur 2'"

 Mexico to Brazil]. 



7 XJ yriocysta St. Eil. Leaves whorled along the immersed floating stem, and at 

 the base oT the scape : 'bladders subglobose, numerous on their capillary segments ; scapes
