Ranunculus Limosella, F. Mueller. MS. 



A stoloniferous aquatic herb, stems submerged, slender, glabrous, leaves 

 solitary or in pairs, miich shorter than the petioles, J"-3" long, quite entire, 

 linear-oblong or spatulate ; flowers minute, one-eighth of an inch in diameter, 

 solitary or rarely two together, pediincles very slender, shorter than the 

 leaves, sepals 4, ovate apiculate, with membranous margins, petals 4, linear 

 purple, acute, recurved at the tips, thrice as long as the sepals ; stamens 8-12, 

 filaments twice as long as the ovate anthers, pistils usually 8, gradvially 

 tapering into the almost straight capillary style, ripe carpels somewhat swollen 

 at the base, lax, style recurved, one-fourth of a line long. 



Forming matted patches on the shores of lakes and in water not more than 

 ten feet deep, but only flowering on the shores, where the entire plant is 

 minute and easily overlooked, or may be readily mistaken for Limosella 

 aquatica. In habit resembling R. pachyri'hizus, Hook, f, but is more closely 

 allied to R. rivularis, Banks and Sol., and is at once distinguished from all 

 New Zealand sj^ecies of the genus by the quaternary arrangement of the floral 

 organs.
