The following Conspectus of the above species of Utricularia was drawn up for, and published in, my 



Illustrations of Indian Botany. I reproduce it here under the impression that, as the essential distinctive 

 features only are introduced, it may prove a useful aid in their discrimination by directing attention to the 

 more important points of the character of each. 



COJVSPECTUS OF IJVDMJ^ UTRICULARIM. 



Floating. (Calyx lobes herbaceous, not covering the capsule.) 

 Calyx equaling the capsule, at length diverging. Seed peltate, wingless. 



Scapes with a whorl of floats below the flower. - - . - 



Scapes without floats. .-•-.-- 



Calyx shorter than the capsule, appressed, seed flat, bound with a wing. 

 Scapes 3^- or more flowered, seed-wing dentate. (The flowers of this species appear 



blue, all the others of this group have them yellow.) Mergui. 

 Scapes two-flowered, seed-wing entire. - - • - - 



Terrestrial. (Calyx lobes enlarging, becoming, in fruit, sub-scariose, converging and 



covering the capsule.) 

 Calyx lobes ovate, sub-acute ; scales and bracts attached by the base. 

 Seed finely reticulate, ovate, oblong. 



Flowers some shade of blue (not yellow). 



Calyx acute, seed elliptical, obtuse at both ends. 

 Spur shorter than the lower lip, descending. ' . - - 



Spur equaling or exceeding the lip, arcuate, horizontal. 

 Calyx blunt, sub-orbicular in fruit, seed ovate, pointed at one end. 

 Flowers yellow (seed oblong, elliptical). . - - 



Seed finely reticulated, globose. 

 Spur as long or longer than the lower lip. 



Caespitose, leaves sub-spathulate, scapes lax. . - - - 



Distinct, sub-aphyllous, scape sub-voluble. • - - - 



Spur shorter than the lip, scape straight, erect. ... 



Seed scrobiculate, flowers blue. 

 Scales on the scape few, appressed. 

 Pedicels longer than the flower. 

 Spur about the length of the lip. 



Upper lip of the corolla sub-orbicular. Seed simply scrobiculate 



(flowers as large and like those of U. reticulata). - - - 



Upper lip linear, truncated, seed foveolate (flowers much smaller than those 

 of the above plant : apparently aquatic, growing in shallow water). 

 Spur much shorter than the lip, pedicels long. 

 Pedicels shorter than the flower. 



U. stellaris. 

 U. fasciculata 



U. punctata. 

 U. diantha. 



U. reticulata.

 U. Wallichii. 



U, conferta. 

 U. uliginoides 

 U. uliginosa. 



U- Smithiana. 



U. Grifiithii. 

 U. pedicellata. 



Flowers subsessile or very short pedicelled ; upper lip of the corolla emarginate. U. brachypoda 



aflinis. 



Flower distinctly pedicelled, upper lip of the corolla entire. 

 Scales of the scape numerous, sub-cemuous (not appressed). . . • 



Seed papillosely hispid, flowers yellow (scales on the scape sub-foliaceous). 

 Calyx lobes obovate or sub-orbicular, bracts and scales attached by the middle or 



above the base. 

 Seed glochidiate, scales attached a little below the middle, lower lobe obtuse (seed 

 ovate oblong, acute at one end: lobes of the calyx very unequal: spur conical: 

 upper lip emarginate, under sub-orbicular, spreading, 5-toothed : leaves orbiculato- 

 spathulate, scape flexuose). - -.--.- 



See4^eticulated not glochidiate, scales attached by the middle, acute at both ends. 

 Flowers sub-sessile. ' 



Spur longer than the lower lip. 

 Flowers somewhat remote, sub-racemose. - - • - 



Flowers congested, spicate on the apex of the scape (the flowers of both these 

 are nigrescent in drying, but do not appear to differ in colour, hence I sus- 

 pect an error in the name c<Brulea). - - . ^ . 

 Spur shorter or about the length of the lip (lip large revolute on the margin, 

 covering and nearly concealing the spur). .... 

 Flowers longish, pedicelled, seed scrobiculate. • - - -
