DESCRIPTIONS OF HITHERTO UNRECORDED AUS-TRALIAN PLANTS, WITH ADDITIONAL PHYTO-GEOGRAPHIC NOTES. By Baron von Mueller, K.C.M.G., M. & Ph.D., F.R.S. BORONIA AdAMSIANA. Vestitnre extensive, consisting of copious soft partly spreading hairlets ; leaves small, trifoliolate, sessile ; leaflets devoid of stalklets, from ovate-to lauceolar-elliptic, flat ; flowers axillary, solitary, on very short and thia pedicels ; sepals nearly as long as the petals, much invested with hairlets, broad-linear towards the base, gradually narrowed upwards, acute at end; petals contiguous at the margin before expansion, pale-red, outside much beset with soft hairlets ; filaments bearing hairlets rather scantily, suddenly pointed at the apex ; anthers pale, cordate, minutely apiculate ; style thin, very short ; stigma minute ; ovularies glabrous. In the eastern interior of West Australia, at Mangowine, with Cyanostegia Turczaninowii ; Miss A. Adams. Height of plant unknown. Leaves copious. Leaflets soft, \-^ inch long. Petals measuring hardly more than ^ inch in length. Fruit as yet not obtained. This probably rare species stands in nearest relationship to B. ternata, but in that plant the indument is veiy short, the leaflets are smaller, the sepals are broader and conspicuously shorter, while the petals are less pointed and on the inner side less glabrous; the fruits of the two may also be difierent. £. ternata, which was not refound since Capt. Roe gathered it more than half a century ago, has recently been obtained near Yilgarn by Messrs. H. S. King and De Courcy Lefroy, during surveys under order of the Hon. John Forrest. Thus now to Endlicher's description, given in 1839, may be added : Anthers
