apex, the lobes rather spreading, blunt ; bracts similar, all grooved in the dry state ; segments of the corolla hardly 
emarginate.

Hab. Mount Sorrell, Macquarrie Harbour, Milligan ; Western Mountains, Archer. — (FL Jan.) 
A very remarkable little species, quite unlike any of those described above. Annual.— Stems in all my speci- 
mens quite simple, 8-4 inches high, nearly erect, perfectly glabrous, leafy. Leaves 3-4 lines long, subereet, very 
broadly cimeate, cut at the top into four to eight sharp, cuspidate lobes, the margins not recurved ; the upper 
leaves are broader, and as broad as long. Spikes cylindrical, 1 inch long, f broad, covered with densely imbricated 
bracts. Bracts very broadly obcuneate or rotundate, often broader than long, pectinately multifid, the lobes each 
simple ami cuspidate. Flowers rather small. Lobes of the corolla emarginate or lobed, with a central apiculus. 
Anthers two-celled ; cells each spurred, slightly hairy along the lines of dehiscence.— The plant turns perfectly black 
in drying. 
Nat. Ord. LX. LENTIBULARIEiE. 
A very largely-represented Natural Order in all parts of Australia, though with few exceptions the 
species are all referable to the genus Utricularia ; twenty-four species were known to Brown, to which 
bare since been added about ten more. 
Gen. I. UTRICULARIA, L. 
Calyx alte bilabiatus, labiis subsequalibus. Corolla bilabiata, labio posteriore basi calcarato. Sta- 
mina 2; filamentis apice intus antheriferis, antheris 1- v. sub-2-locularibus. Ovarium 1-loculare; ovulis 
plurimis, placentas basilari libero globoso affixis ; stylo brevissimo ; stigmate uni- v. bilabiato v. disciformi. 
Capmla polyspermy. Semhia parva, exalbuminosa ; embryone tereti, interdum indiviso. — Herbse tenella, 
aquatica v. paludosa ; foliis radicalism simplicibus v. decompositis radiciformibus v. vesiculiferis ; scapis 
ivdls v. Iraeteol fw, saphu indivms l-floris v. spicatis v. racemosis. 
The species of this curious genus are, almost without exception, water or marsh plants, sometimes having long, 
Boating, Blender stems, covered with multifid, capillary leaves, that bear minute air-bladders and erect scapes ; the 
terrestrial species again have often small, linear, inconspicuous leaves, and sometimes bladders also, attached to the 
root? or near them . the bladders are frequently open, and provided with a fringed operculum: they are beautiful 
microscopic objects.— Flowers on slender, naked, or rarely bracteate, filiform scapes, solitary or spicate, rarely sub- 
racemoee, white, .yellow, pink, or blue, very delicate. Calyx two-lipped; lips large, equal, entire, often very con- 
vex. Corolla two-lipped ; upper entire or two-lobed ; lower entire or three-lobed, its palate often provided with 
projections, spurred behind. Stamens two, ascending, placed at the throat of the corolla. Anthers one-celled, or 
constricted and spuriously two-celled, adnate to the inner face of the filaments. Ovary globose, one-celled, with 
many ovules on a globose, free, central receptacle. Style short, with a lobed or discoid stigma. Capsule two-valved, 
one-celled, many-seeded. (Name from utriculus, a little bladder.) 
1. Utricularia Australis (Br. Prodr. 431) ; natans, caulibus intertextis, foliis capillaceo-multifidis 
vesiculiferis, scapo aphyllo paucifloro, ftoribus flavis, labiis indivisis inferiore duplo longiore quam lato, cal- 
care ascendente antice piano subtus carinato. {Gunn, 1225.)
