THE VICTORIAN NATURALIST. 57 



Generality of leaves from ~/i to nearly i inch long, nearly 

 iV-inch broad, hardly or moderately spreading. Primary peduncles 

 1-2 inches long, rather firm, the secondary peduncles also rigidul- 

 ous, about i inch long, supporting the floral leaves, tardily 

 deciduous. Umbellules never subdivided. Petals long persistent, 

 marginally overlapping before expansion. Stamens and styles 

 about as long as the petals. Fruits measuring about To-inch, but 

 not obtained in a perfectly ripe state. This species comes 

 nearest to T. valida, but the leaves are much smaller, and those 

 which form the involucre hardly shorter than the others, which 

 gives the plant quite a unique appearance among its congeners ; 

 further, the involucellar bracts are much shorter than the pedicels, 

 the flowers all becoming fruit-bearing, the fruits smaller with 

 proportionately less width, and the carpophore has only a ter- 

 minal fissure. From most congeners different in the colour of the 

 petals. In some respects this new plant reminds of some species 

 of Astrotricha, particularly A. Biddulphiana. 

 Trachvmene Eatoni^e. 



Tuberous, glabrous ; branches slender ; leaves lax, filiform- 

 linear, hardly acute, lobeless ; peduncles thin, surpassing the 

 leaves ; involucrating bracts very short, pointed ; pedicels capil- 

 lary ; calyx-denticles acute, but minute ; base of styles much 

 dilated ; fruit considerably compressed, quite as broad as its 

 length, its ridglets filiform-narrow, but prominent.

Tuber ovate-roundish, nearly 2 inches long. Leaves numer- 

 ous, ^-1 inch long, usually very narrow. Pedicels ^-inch long, 

 or somewhat shorter. Many of the flowers unproductive. Petals 

 and stamens as yet unknown. Dilation of styles longer than the 

 capillary portion. Fruit measuring about ^3-inch, but not yet 

 obtained in a fully ripened state. This species is by its tubers 

 already distinguished from all others, except T. deflexa and T. 

 cirrusa, but systematically it ought to be placed near T. effasa, 

 from which the longer, narrower and laxer leaves, as well as the 

 evidently larger fruits, already distinguish it. 



T. deflexa occurs on the sources of the Blackwood-River (Th. 

 Muir). The tubers of this species are egg-shaped, carnulent, 2-3 

 inches long, and eaten by the aborigines. T. tenuissima was 

 collected by me on the Collie- and Preston-Rivers, as well as on 

 the Shannon. Divisions of root thin and short, seemingly indi- 

 cating only annual duration. Fruits considerably longer than broad. 



T. effusa extends inland to Lake Seabrook (Merrall) ; it occurs 

 also near Mount Rugged (Miss Brooke). 



The genus Siebera, among composite plants, as the latest under 

 that name adopted by Bentham, abrogates that generic appella- 

 tion among umbelliferous plants. It seems therefore best to 

 leave the former generic names undisturbed, more particularly so 

 as Rudge indicatingly comprised modern species of Trachymene
