slight basal intrusion, seau-ily reticular-rongh, the linear promiuence 

 between the marginal and commissural narrow linings faint ; carpophore 

 persistent, oleft at tbe snmmit only. 



In Eucalyptus-scrubs near the north-side of the Stirling s Ranges ;. 

 George Maxwell. 



A shrub of about 3 feet in height. 



Generality of leaves from * 3 to nearly 1 inen long, nearly 1 /i2-inch 

 broad, hardly or moderately spreading. Primary peduncles 1 — 2 inches 

 long, rather firm, the secondary peduncles also rigidulous, about 1 inch 

 long, supporting the floral leaves. tardily deciduous. Umbellules never 

 subdivided. Petals long persistent, marginally overlappiug before expansion. 

 Stamens and styles about as long as the petals. Fruits measuring about 

 Vo-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. terminal rissure. 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. 



Trachymene Ealonim. 



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

 ac\ite, lobeless ; peduncles thin, surpassing the leaves ; involucrating bracts 

 very short, pointed ; pedicels capillary ; 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. 



Near Youndegin; Miss Alice Eaton. 



Tuber ovate-roundisb, nearly 2 inches long. Leaves numerous, 

 Vs — 1 inch long, usually very narrow. Pedicels 1 /s-inch long, or somewhat 

 shorter. Many of the flowers unproductive. Petals and stamens as yet 

 unkown. Dilation of styles longer than the capillary portion. Fruit 

 measuring about \/s-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. cirrosa, but systematically it ought to be placed near 

 T. effusa, 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 (T h. M u i r). 

 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 indicating only annual duration. Fruits 

 considerably longer than broad. 



T. eßusa 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, ahrogates that generic appellation among 

 umbelliferous plants. It seems therefore best to leave the former generic 

 names undisturbed, more particularly so as Rudge indicatingty comprised 

 modern species of Trachymene (along with the subsequent Didiscus 

 albiflorus) in the genus Trachymene already, further as the designation 

 Didiscus has been in extensive horticultural use for fully sixty years, 

 and therefore could not well be abolished now. Sprengel's name, Fischera, 

 given as far back as 1813, is neitber available, as a synchronous genus 

 hecame undisputably admitted among asclepiadous plants. 



Didiscus elachocarpus. 



Annual, dwarf, erect, beset with spreading glandule-bearing hairlets ; 

 leaves few, minute, trifid ; involucral bracts broadly linear, acute, ahout 

 as long as the pedicels ; fruitlets extremely small, dark-brown, almost 

 obovate, turgid, glabrous, but equally tubercular-wrinkled on both sides.

 Whole plant above ground about 2 inches high, according to an only 

 specimen secured : root almost as long, simple, downward capillary-
