[Sida Spenceriana. 



Dwarf; branchlets, leaves, stalks and calyces closely covered with 

 orbicular silver-shining densely ciliated scales ; stipules linear-setaceous ; 

 leaves from a roundish verging to an ovate form , irregularly denti- 

 culated ; peduncles thread-like, one-flowered, much exceeding the leaves 

 in length, soon glabre^cent ; lobes of the calyx almost deltoid ; fruitlets 

 rather numerous, broader than high, much compressed, oblique-ovate, 

 short-pointed at the summit, prickly at the back, narrowly reticulated 

 at the sides , hardly or tardily dehiscent , not surpassing the calyx in 

 length ; seed slightly downy. 



At Yappunyah and Thargumindah, close to the Paroo-River; Mrs. 

 F. Spencer. 



An only specimen obtained without flowers. Leaves V'-~1V2 inch 

 long, flat, on stalks of moderate length. Flowerstalk about 4 inches 

 long, jointed near the summit. Fruit-bearing calyx not half an inch 

 wide. Fruitlets nearly i/ß inch broad, almost flat. 



These characteristics may require modifications from future exami- 

 nation of ampler material. The species is clearly allied to S. corrugata, 

 but remarkable for its scaly vestiture and much elongated peduncles; 

 the fruitlets are more numerous, thinner, suddenly short-pointed and 

 prickly , in which latter respects our new plant comes nearer to S. 

 echinocarpa , difl'ering however much in indument , great length of 

 flower-stalks and larger fruitlets not very conspicuous surpassed by the 

 calyx, nor forming a very dcpressed total fruit. 



Styphelia costata. 

 (Leucopogon costatus, F. v. M. coli.) 

 Branchlets numerous, mostly spreading, glabrous; leaves small, fi-om 

 a lanceolar verging into an ovate or cordate form, short-stalked, of 

 thick consistence, equally green and somewhat shining on both sides, 

 curvc'd- spreading, gradually attenuated into the liluntish summit, 

 claspingly bent inward, slightly ciliolated, otherwise glabrous, longi- 

 tudiiially strongly five-nerved, the veins between the outer nerves and 

 margin also prominent and ascending ; flowers small , crowded at the 

 summit of the branchlets, not numerous ; bracteoles rhomboid-cordate, 

 somewhat c.ymbiform , not fully half as long as the ovate -lanceolar 

 scpals, and as well as these shortly and densel}' ciliolated and slightly 

 downy ; corolla small, white, its tube hardly as long as the calyx, the 

 lobi's densely bearded ; anthers conspicuously tipped ; style very short, 

 as well as the ovary glabrous.
