R. Gunn, Esq. (n. 880). 
A small, much branched, slender, wiry annual. Stem short, 
branching from the base, and there very leafy. Leaves small, 
tripartite, and much cut and divided. Umbels small, 2-5- 
flowered. Involucre of 2-3 leaves. Calyx-lobes or sepals erect. 
Petals narrow, entire, reddish. Styles curved. Stylopodium 
large and conspicuous. Fruit broadly cordate, compressed. 
The habit of this is very different from any described Xanthosia ; 
and should perhaps, with one or two others in Herb. Hook., form 
4 separate section of the Genus. The carpels exactly resemble 
those of the sections Leucolena and Euxanthosia. J. D. H.
