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

 — Terrestrial scapes {Oligocysta, A. DC). 



2. U. amethystina, St. Hil. 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 ronndish, en- 

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

 ceeded by the conical-cylindrical, bluntish, or pointed sjtur. — Mart. PI. Bras. 9. t. 21./. 1, 

 t. 22./. 6: larger-flowered, and with larger ovate-roundish leaves. — U. modesta, A. hc.l 

 {in PI. Paspp.). V. globularifolia, var. minor, Benjam. I {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 stolonlferous : bladders rare, minutely globose, subsessile ; stem 4"-12" high ; 

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

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



3. U. pusilla, 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 V'-SV high ; leaves l"'-2"', pe- 

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

 Trinidad !, Cr. ; [Guiana, Brazil}. v , 



1/ 4. X7. 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 ; csdyx-segments elliptical ; corolla 

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

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

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

 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 1 to Brazil !]. 



5. V. angustifolia, Benjam. I Scajje slender, filiform, somewhat rigid, flexuose: 

 scales and bracts exauriculate, minute, very distant j 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-ronnd- 

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

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

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

 spur 3'" long ; corolla pale-blue {Cr), yellow {Kegel).— li.k.B. Trinidad 1, Pd., Cr., in 

 moist, sandy savannahs, Arima, Omeara, Aripo j [Guiana I]. 



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

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



6. U. obtusa, Sw. leaves whorled along submersed interwoven stems, and at the base 

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

 filiform devoid of scales; raceme lax, few-flowered: bracts sheathing, traneate-rbundishi 

 single, 'exauriculate': pedicels distant, spreading, as long as the internodesj calyx-segments 

 ronndish; corolla- maa&, yellow . lips entire or inferior subentire, nearly as bng or httle 

 exceeded by the mbulate, bluntish, incurved jpar.— Scape 6"-2", pedicels 4^"-6" spur 2 

 long.— Hab. Jamaica!, M'Nab, Wils., Wullschl., in rivulets; Tnnidad!, Or.; [Cuba and 

 Mexico to Brazil]. 



7 U myriocysta, St. Hil. Leavea whorled along the immersed floating stem, and at 

 the base of the .scape: bladders subglobose, numerous on their capillary segments ; scapes
