1030 LXXXII. GENTlANEiE. [Limnanthemum.. 



lin. diameter, the lobes scarcely fringed on the margin, sparingly bearded at 

 the base, and without the longitudinal wing of L. crenatum. Ovules spreading 

 over the greater part of the inner surface of the ovary. Lobes large, petal-like, 

 spreading, crenulate or fringed. Capsule membranous. Seeds numerous, 

 slightly compressed, smooth tubercular or muricate, J to fully ^ line diameter. — 

 Villarsia geminata, R. Br. Prod. 457 ; F. v. M. Fragm. vi. 137. 



Hab.: Shoalwater Bay, R. Brown; Brisbane Eiver, F. v. Mueller ; Moreton Bay, O'Shanesy. 



The seeds seem to be as variable in this as in other species as to their size, and the smooth 

 or muricate surface. I have not seen the seeds, however, of Brown's or other tropical specimens, 

 which may possibly belong to the following species or variety. — Benth. 



5. I., hydrocharoides (Hydrocharis-like), F. v. M. Herb.; Benth. Fl. Austr. 

 iv. 380. A creeping plant, closely resembling the smaller and less developed 

 specimens of L. geminatum. Leaves in dense tufts, on long petioles, broader and 

 less deeply cordate than in L. geminatum,, and often only truncate at the base. 

 Corolla yellow, rather smaller that in that species and the seeds larger, densely 

 and minutely velvety-pubescent. — Villarsia hydrocharoides, F. v. M. Fragm. vi. 189. 



Hab.: Rockingham Bay, Dallacliy. 



6. !■. exiliflorum (flowers small), F. v. M. Fragm. v. 46 ; Benth. Fl. Aicstr. 

 iv. 881. A slender plant with creeping stolons. Leaves tufted on long petioles, 

 ovate-orbicular or reniform, truncate or cordate at the base, from under ^in. to 

 about Jin. long. Flowering stems very slender, decumbent or ascending, simple 

 and leafless, or once or rarely twice branched with a small petiolate leaf at the 

 branch, ^ to 1ft. long. Pedicels filiform, usually 2 together or clustered at the 

 nodes. Flowers very small, yellow. Calyx-segments ovate, membranous, 

 scarcely 1 J line long. Corolla shortly exceeding the calyx, the lobes slightly 

 fringed on the margin (or entire ?), bearded with a few cilia inside towards the 

 base. Capsule ovoid, not exceeding the calyx. Seeds globular, with minute 

 reticulations or glands, giving them a pubescent aspect when dry.— Villarsia 

 exiliflora, F. v. M. Fragm. v. 46, vi. 187. 



Hab.: Stagnant waters, Eookingham Bay, Dallachy ; Fraser's Island (some specimens 

 collected by Miss Lovell seem to belong to this species, but they were in bad condition).
