and its pretty rose or white flowers on short or long pedicels. Gunn has in vain attempted to distinguish two species 
amongst its many forms, and recognizes three different states, one a large one, 5-6 feet high, straggling amongst 
and over other shrubs ; it is very common everywhere : secondly, a smaller form, covering acres, erect and 3-4 
feet high, with spreading branches ; and thirdly, a dwarf variety, erect, but with the branches depressed or pro- 
strate, forming great patches on the ground.— Plate XXXI. Fig. 1, portion of branch and leaves ; 2, flower ; 3,

plant has been referred by Endlicher to Dillmiacece, with which Order it has 
certainly many characters in common, perhaps more than with Cunoniacea, but from which it differs remarkably in 
habit, in the coriaceous, evergreen, shining foliage, terminal, racemose inflorescence, quaternary floral whorls, per- 
sistent sepals, loose, membranous testa, oily, fleshy albumen, and minute, globular embryo j it is however allied to both 
the BilUniacex and Magnoliacem in the hypogynous stamens and petals, adnate anthers with lateral dehiscence, and 
free, stipitate carpels, which latter aTe however more like those of Crasmlacece than of any other Order. In the 
alternate, exstipulate leaves, it differs from (hmmiacea, and agrees with Jnopterm and Escallouice, but differs from 
these again in the free carpels ; the structure and consistence of the albumen and embryo is altogether that of 
Jnopterus.^A small, woody shrub, C inches to 1 foot high, with erect, simple, or sparingly branched, sulcate stem. 
Leaves alternate, shortly petioled, obovate-oblong or obovate-lanceolate, tapering at the base blunt or retuse un- 
equally serrate, very coriaceous, deep green and shining, about 1 inch long. Flowers in erect, terminal racemes which 
are 1-2 inches high, white, | inch long. Pedicels slender, with a minute toothed bract at the base. Sepals four, 
small, muted at the base, ovate, spreading. Petals four, erect, obovate, clawed, imbricate. Stamens eight alter- 
nate and opposite the petals and of equal length with them, hypogynous; filaments very slender; anthers linear- 
oblong, adnate to the filament at the base, blunt, with lateral dehiscence. Ovaries four, linear-oblong, stipitate,
