Polygala Tepperi. 



Herbaceous, erect or ascending, much beset with very short appressed 

 hairlets; leaves rather short, narrow linear, acute; flowers small, axillary 

 or lateral, solitary or in som instances two together; pedicels very short, 

 so also the peduncle if present ; bract and bracteoles quite minute, per- 

 sistent ; outer sepals ovate-lanceolar, disconnected; inner sepals greenish, 

 lanceolar, slightly falcate, their venules hardly perceptible ; middle lobe 

 of anterior petal conspicuously fringed, lateral petals pale, upwards dilated 

 and nearly truncate ; free part of filaments of most of the stamens very 

 short; ripe fruit fully as long as the lateral sepals, acutely bilobed ; seeds 

 strophiolate, bearing a whitish silk-like vestiture. 



Roebuck-Bay; W. Tepper. 



Allied to P. chinensis, differing from the narrow form of that species 

 -already in often solitary flowers and in longer not rounded fruit-lobes. 



Polygala stenodada, in its typical state, has been sent from Port Dar- 

 win by Mr. M. Holtze ; the leaves attain two inches in length, the racemes 

 inclusive of the peduncle four inches, the pedicels 1 /4-inch ; the anterior 

 petal is towards the summit blue, and is cleft into only few lobes, which 

 are thickish ; the free part of the filaments is conspicuously longer than 

 the anthers; the fruit has rounded-blunt lobes and no marginal expansion. 

 The broad-leaved plant, referred to P. stenodada as a variety by Bentham, 

 has the pedicels shorter, the anterior petal more fringed and pink, and 

 the fruit broader; this plant seems also always dwarfer and less slender, 

 while the leaves are shorter. It. approaches P. diinensis, but the racemes 

 are elongated. It is now known also from the Don-River (Bird), the 

 Elliot- the Cape- and the Burdekin-River (Bowman), the Kimberley-District 

 (Nyulasy). 



Polygala rhinanthoides occurs also at Port Darwin (Holtze), Thursday- 

 Island (Ref. James Chalmers). Leaves may be seen 2 1 /« inches long; the 

 racemes contain in some instances as many as 30 flowers ; the inner sepals 

 occur not seldom in a marked way quilateral and acuminate. The plant 

 is very closely related to P. persicarijoUa. 



Polygala arvensis is now known southward as far as the Paroo (Mrs. 

 Spencer). Polygala leptalea and Salomonia oblongifolia were found also 

 at port Darwin by Mr. Holtze. 



Helipterum Fitzgibboni. 



Annual, rather dwarf, beset with very short glandule-bearing hairlets ; 

 leaves broad-linear, darkish-green, somew r hat clasping at the base, revolute 

 along tbe margin, usually blunt ; headlets small, turbinate-hemispheric > 

 singly terminating bi'anchlets, closely approached by leaves, nodding; 

 involucral bracts in many rows, all acuminated ; the uter from reddish 

 to black-brow n, ciliolated ; lamina of the inner white, comparatively broad 

 the stipes of these, except the innermost, thin, lanugiuous near the la- 

 mina; receptacle much depressed; anthers soon almost completely exserted; 

 achenes glabrous, rather pale, truncate, somewhat transparent; biistlets of 

 pappus 6 — 12, short-plumous, j'ellowish at and towards the summit.
