This remarkable little plant, first described in the 'London Journal of Botany,' from incoiir, 
was placed by me in Portulacea ; and I am indebted to M. Planchon for pointing out its true affinities, which 
are undoubtedly with Villarsia and Limnantkemum, differing from both in the absence of glands at the base of the 
ovary, and in the glabrous corolla, and further, from Villarsia in the not capsular fruit, and from /. 
the habit and foliage. Liparoplnjllum Gnnnii is a very small herb, 1-2 inch.-.- high, re.embli^ a dwarf Mate of 
Claytonia Australasica.— Rhizomes long, cylindric, branching, sending down long, ver\ thick, simj. 
short. Leaves linear, 1 inch long, \ broad, subacute, fleshy, quite entire. Peduncle shorter than the leaves, termi- 
nal, erect, one-flowered. Flowers about \ inch diameter. G%*-lobes five, acute. Corolla short ; lol.es live, ob- 
long, blunt, with a thick fleshy disc, and undulated, broad, membranous margins. Fruit globose ; seeds numerous. 
compressed, nearly orbicular, bright yeUow. (Name from \umpos,fat, and tfrvWov, a leaf.)

Nat. Ord. LIIL LOGANIACEiE. 
The plants constituting this Order have been lately ably discussed in the 'Journal of the Linnean 
Society' by Bentham, who has shown that they are an artificial assemblage of anomalous members ot 
Rubiacea, Gentianea, Scrophularinea, and Apocynea. 
The Australian species (about forty-five in number) all belong to the genera Logama Mdrasaone 
and StrycAnos; of these Bentham has shown that the affinities oi Log ana are ^Scrop^n^ ro... 
than with Rubiace. or Apocyne. ; that Mitrasacne corresponds with the tribe IMyoU* of &* „ . 
many important part.culi, but has the adhering stigmata of Apocyne*; and that Strychnos, t ,,, , .... 
no ^parallel in Rubiace. and Apocynea, is aUied to both. These plants are for the most I . < ■ 
of the eastern coast, but several are tropical (including Strycknos), and some nat.es of the 8*. Kner 
Colony.
