DESCRIPTIONS OF NEW SPECIES. 



By Baron Sir F. von Mueller and Professor R. Tate. 



Eriostemon argyreus, F. v. M. and Tate. 

 Yery lepidote all over, with narrow- or elliptic-lanceolar leaves, 

 but gathered without any flowers or fruits. Allied to E. anceps 

 as far as foliage is concerned. Central Australia. 



SiDA PODOPETALA, F. v. M. and Tate. 



Extensively bearing a close but short indumentum ; leaves 

 rather small, on short petioles, from orbicular- to lanceolar-ovate, 

 irregularly denticulated except towards the base ; stipules linear- 

 filiform, early deciduous ; peduncles mostly axillary and solitary, 

 articulated near the flower, as long as the latter ; calyx compara- 

 tively large, its lobes deltoid, shorter than the tube or nearly as 

 long ; the latter semiovate or Anally almost semiglobular, faintly 

 many-streaked ; petals yellow, nearly equilateral, by about one- 

 third longer than the calyx, slightly bilobed, the upper half much 

 dilated, the lower half cuneated and towards the base densely 

 ciliolated ; staminal tube short ; styles numerous, only connate 

 near the base ; ovularies much beset with very short hairlets, 

 connected into a much depressed mass, and this surrounded by a 

 conspicuous, someAvhat crenulated, disk. Central Australia. 



This plant has the aspect of an AbutUon, but its ovularies are 

 uniovulate. The width of the expanded flowers is somewhat 

 more than an inch. The form of the petals is rather exceptional 

 in the genus, they being somewhat suddenly contracted into the 

 long, almost stalk-like basal portion. 



Tliis species differs from S. cJeisocalyx in broader and pointed 

 leaves, in longer peduncles, and in organization of the flowers, 

 though >S'. cJeisocalyx may be dimorphous and is known to us as yet 

 in the clandestinely flowering state only ; the fruits of the two 

 may also be different. From >S'. i:)latycaJ.yx our new plant is 

 separated by narrower leaves, by the calyces being not provided 

 wdth very prominent ridgiets, and further by the petals emerging 

 beyond the calyx. 



Calotis LATiuscuLA, F. V. M. and Tate. 

 Erect, rather robust, beset Avith short scattered hairlets ; leaves 

 comparatively large, those of the branches simply sessile or Avith 

 broad base somewhat clasping, from cuneate- to elliptic-lanceolar, 

 flat, indented towards the summit or quite entire ; headlets of 

 flowers arranged in almost corymbous panicles, on slender 

 peduncles ; involucral bracts nearly lanceolar ; floral ray yelloAv ; 

 solid portion of fruit almost broader than long ; spinules generally 

 9 to 10, beyond the base disconnected, feAv much shortened, the
