EucaLyptus Preissiana. Schauer, in Lehm. Pl. Preiss. p. 131. 
A handsome tree-like shrub, of which Dr. Schauer says, 
“species inter omnes tam habitu quam characteribus maxima 
insignis”; with the foliage fragrant (like that of the Myrtle), 
when bruised, and flowers of rather a large size; rendered more 
conspicuous by the copious yellow stamens, spreading far beyond 
the diameter of the cupula. It is a native of Western Australia 
Whence seeds have been sent from Dr. Preiss of Swan River, to 
the Royal Gardens of Kew, and dried specimens both by him 
and by Mr. Jas. Drummond. Dr. Preiss’ specimens are more 
distinctly indicated as natives of Cape Riche (no. 209, Preiss. 
Herb.), and as rising to a height of eight feet. Our plant 
flowered in the summer of 1846, when it had attained a height 
of five feet. It thrives in a cool Greenhouse, and in the summer 
is the better for standing in the open air. 
Descr. Shrub, having a tree-like mode of growth, from five 
to eight feet high, erect, branched ; branches spreading, the main 
ones like the stem rounded and pale-brown : the ultimate ones 
red-purple, with usually four sharp angles. Leaves opposite, on 
short petioles, elliptical, vertical, dark green (costa prominent 
and red on both sides), the margin entire, often edged with red,
