NAT. On». LXV. LENTIBULARIA, Rich. 
Gen. I. UTRICULARIA, Z. 
Calyx 2-phyllus; labiis «equalibus, indivisis. Corolla personata; labio inferiore basi calcarato. Stamina 
2; filamentis apice intus antheriferis. Stigma 2-labiatum. 
A very large genus, whose species abound in watery and marshy places of both hot and cold climates, some- 
times in wet moss; many kinds float by means of minute bladders attached to the stems and leaves, some terrestrial 
kinds are likewise thus provided. Calyx of two leaves. Corolla two-lipped. Stamens two. Ovary globose. Stigma 
discoid, cup-shaped, or two-lipped. (Name from utriculus, a little bladder.) 
1. Utricularia Nove-Zelandie, Hook. fil.; radicibus vesiculiferis, vesiculis pedicellatis, scapo simplici 
erecto apice 1—4-floro, foliis deciduis radicalibus lineari-lanceolatis carnosulis 1-nerviis, bracteolis late ovatis 
obtusis, pedicellis brevibus, calycis labio superiore orbiculari retuso v. bilobo multinervi inferiore cochleato 
obscure 3-dentato, eorolle labio superiore cuneato retuso inferiore late securiformi margine integerrimo, 
caleare porrecto obtuso. 
Has. Northern Island. Wet rocks at Palliser Bay, Colenso. 
A minute slender herb, with fibrous roots, covered with pedicellate bladders, and a simple thread-like scape, 
bearing three to four flowers. Leaves few, all radical, linear-lanceolate. Bracts broadly ovate, blunt. Flowers 
white, shortly pedicellate. Calyx two-lipped ; upper lip orbicular, retuse, or two-lobed ; lower concave, obscurely 
three-toothed. Corolla two-lipped ; upper lip wedge-shaped, retuse; lower broadly axe-shaped, margin entire; spur 
projecting, blunt.—Nearly allied to the Tasmanian U. dichotoma, but much smaller; also near U. monanthos, but 
the spur is longer, and the scape bears more flowers. 
2. Utricularia Colensoi, Hook. fil.; omnia U. Nove-Zelandie sed corolle labio superiore lineari- 
oblongo bilobo inferiore late cuneato 3-lobo, lobo medio retuso, disco 3-gibboso. 
Haz. Northern Island. East coast, Colenso. 
My only specimens are preserved in camphorated spirits of wine, and hence not easily examined; but they 
appear to differ conspicuously from the former in the linear two-lobed upper lip, and broadly wedged-shaped three- 
lobed lower, which has three swellings on the disc. 
3. Utricularia protrusa, Hook. fil.; natans, caule elongato, foliis capillaceo-multipartitis vesiculiferis, 
scapo erecto valido 2—4-floro, sepalis ellipticis, corollæ labio superiore 3-lobo inferiore subquadrato mar- 
ginibus recurvis fauce protrusa, calcare brevi obtuso. 
Has. Northern Island. Bogs, Bay of Plenty, Colenso. 
The specimens were preserved with U. Colensoi, and the character may require much correction; it is the 
only long-stemmed floating Utricularia 1 have seen from New Zealand. Stems a span long, covered with capillary 
leaves and little bladders. Scape stout, transparent, with a few yellow flowers. Upper lobe of corolla three-lobed ; 
lower broad, with the disc bulging out and margins recurved. Spur short, blunt.
