OTHER ANNOTATIONS ;

Grevillea Williamson:. 



Diffuse ; leaves small, rigid, broadish- or ovate-lanceolar, 

 mucronate, beneath as well as the branchlets somewhat tomen- 

 tellous and slightly sericeous, above glabrescent, at the margin 

 but slightly recurved ; flowers small, in short unilateral almost 

 spicate racemes ; bracts very short, but comparatively broad, 

 fugacious ; petals blunt, somewhat reddish or partly greenish, 

 inside downward glabrous, outside scantily beset with hairlets ; 

 style thin, reddish, more than half exserted, at first much re- 

 curved, glabrous ; stigma very small, convex, obliquely terminal, 

 hardly longer than broad ; hypogynous glandule extremely short ; 

 ovulary almost sessile villosulous-tomentellous. 



In valleys between Mount Abrupt and Mt. Sturgeon ; H. B. 

 Williamson. 



Height to three feet. Leaves short-petiolated, Y^-Yz inch 

 long, acuminate. Peduncles short, tomentellous. Racemes 

 about one inch long, when young more conspicuously in- 

 dumentous. Flowers about a dozen in the raceme. Corolla 

 through its recurvature hardly yi inch long. Fruit not yet 

 obtained. Aspect of G. mucronulata, but the pedicels are much 

 shorter, the flowers are smaller and generally more numerous on a 

 more elongated rachis, none of the petals are barbellate inside, the 

 style is thinner, quite glabrous, proportionately longer and thus 

 more exserted, and the stigma is less lateral. Moreover G. 

 mucronulata is restricted to the most eastern regions of New 

 South Wales. Indeed real affinity draws our new species nearer 

 to G. ilicifolia and G. Aqm/oliu7n, notwithstanding the extreme 

 difference in the foliage ; besides, pedicels and stipes are also 

 shorter, while the stigma is more depressed and smaller; the 

 fruit may also prove different. Broad-leaved forms of G. australis 

 approach somewhat our new plant in aspect ; but its inflorescence 

 is totally different, the ovulary is not glabrous, nor the stigma 

 dilated, in our new plant. 



In the last number of the Victorian Naturalist by a clerical 

 oversight the name of the writer on Adansonia was omitted ; the 

 communication was from Mr. ^neas Gunn. 



New or Rare Victorian Plants. — The habitats of the new 

 Victorian plants in the list published in this number are indicated 

 by letters signifying the divisions of the colony used in part 2 of 

 " The Key to the System of Victorian Plants." It is also intended 

 to publish occasionally woodcuts of rare Victorian plants in con- 

 ormity with those contained in the abovementioned work.
