156 FLORA OF TASMANIA. {Umbellifera.

The Tasmanian specimens appear to be a small state of a very much more robust plant which .Mueller ha> 
sent from Victoria (as X dissecta), and which ha- br< adcr. white, membranous, involucral scales. — Roots perennial. 
Stems 3-5 inches long, very numerous, slendei lilih m pro.-trat sj riugly branched. Leaves glabrous, both the 
caidine and radical on slender petioles, tripartite, or twice or thrice cut into narrow, cuneate, sessile, or petiolulate, 
entire or cut, acute lobes. Umbels very small, at the axils of i 
flowered. Involucral scales very small, subulate or la 
mericarps nine-ribbed. Calyx-lohes ovate, deciduous.

This is so very similar to the X pusilla, Bunge, of Swan River and King George's Sound, that I can only 
distinguish it by the broader mericarps ; it is also very near X glabrata, Bunge, of the same country, but is more 
villous.— A small, annual?, tufted plant, more or less covered with long hairs. Stems many from the root, 2-3 
prostrate, not nearly so slender as in X dissecta, leafy. Leaves shortly petioled, cut into three ellip- 
1-oblong or lanceolate, entire or toothed 
segments, whose margins are flat or revolute. and 
faee pale.
