Calotis Kempei, spec. Jiov. (Section AnacantUaria. ) 



Upriglit, short glaudular-downy ; lower ntem-leaves narrow- 

 lanceolar, sessile, remotely and sharply serrated ; upper leaver 

 gradually smaller and toothless ; scales of the involucre ovate- 

 lanceolar, pointed ; ray-flowers yellow ; achenes semiellipsoid- 

 cuneate, tubercular-rough, slightly glandular-downy ; pappus 

 membranous, broadly annular, undivided, rolled inward at the 

 margin, quite destitute of prickles. 



In the vicinity of the Eiver Finke, MacDonnell Eanges, 

 {Bev. H. Kempe.) 



In habit similar to the broad-leaved forms of C. erinacea ; in 

 fruit more like C. cuneifolia and C. dentex, but diifering from 

 these, and indeed from all others, in the form of the pappus — 

 so abnormal that the plant might generically be separated 

 from the other species under the above sectional name. 



Thysanotus exiliflorus. 



Dwarf, smooth ; branches of the panicle dichotomous ; bracts 

 very short, semilanceolar, acuminated ; pedicels mostly two, 

 rarely three together, or solitary, shorter than the flower, 

 jointed below the middle ; flowers exceedingly small ; the inner 

 sepals merely narrowly purple, and very minutely fringed ; all 

 'sepals blunt ; stamens six ; anthers all of nearly equal length, 

 oblong-linear, reaching iip to two-thirds of the sepals. 



On MacDonnell Eanges, E. Giles ; near the Finke Eiver, 

 jRev. H. Kempe. 



The few specimens of this miniature "fringe lily" seen, a 

 span high, accompanied by separate tubers of large size when 

 compared to the stem of the plant ; these tubers smooth, pale, 

 ellipsoid-cylindrical, \^ to 2 inches long, gradually attenuated 

 at each extremity, held by long descending fibres. Leaves, 

 none with the stem; perhaps soon drying up. Sepals only two 

 to three lines long, the inner along the median line broadly 

 greenish ; filaments very short ; anthers oblong-linear, blunt, 

 about one line long ; ovary spherical, thrce-ccllcd, with two 

 ovules in each cell ; fruit not yet obtained. 



This Thysanotus differs from all others in the singular small- 

 ness of its flowers ; in systematic characteristics it approaches 

 as well T. isantlierus as T. asperafus.
