Botanical description. Species, Dalrympleana n.sp. 
White Gum grandissima, cortice saepe maculis clarig et lamellis longis tenuibus secedente, ligno 
carneo. Foliis juvenilibus pallidis cordatis vel orbicularibus vel ovoideis, amplexicaulibus, sessilibus 
vel brevissime petiolatis. Venis patentibus, reticulatis. Foliis maturis petiolatis, lanceolatis, falcatis, 
rare minus 1 dcm. longis et 2 cm. latis, venis patentibus vena peripherica a margine distincte remota. 
Inflorescentia axillare, 3 floribus breve pedicellatis cruciformibus. Alabastrorum calycis-tubo cylin- 
droideo, angulare, operculo conico aequilongo margine commissurata distincte. Fructibus truncato- 
ovoideis, ca 8 mm. diametro, margine rotundata vel plana, non lata, valvis 3 vel 4 mediocriter exsertis. 
A large tree, sometimes attaining an enormous size. ''' I have seen them 30 feet 
in girth, with a barrel of almost 100 feet. They are generally 15 or 16 feet in girth. 
Known locally as ' Mountain Gum ' or ' White Gum.' The trees present a remarkable 
appearance. During early spring the bark is quite white, but later this changes to a 
vivid red (sometimes almost vermilion), and the trunks have the appearance of being 
painted in large irregular blotches. Timber pinkish in colour and dries irregularly." 
(W. A. W. de Beuzeville.) 
Branchlets angular, juvenile leaves scabrous in the earliest stage, pale coloured, 
cordate to orbicular or ovoid, stem-clasping, sessile or with very short petioles, with a 
short innocuous point ; 5 cm. long and 5 cm. broad are average dimensions. Venation 
spreading, reticulated, the leaf dotted with black spots, scarcely seen with the naked 
eye. 
Mature leaves petiolate, lanceolate, usually more or less falcate, rarely under 
1 dm. long and 2 cm. wide, venation spreading, intramarginal vein distinctly removed 
from the edge ; black-dotted. 
Inflorescence axillary, petioles flattened, under 1 cm. long, supporting three 
shortly pedicellate appressed, rarely cruciform, flowers of medium size. The buds with 
cylindroid calyx-tube, angled, with a conical operculum of equal length. Commisural 
rim marked. Anther small, opening in parallel slits. Gland at the back. 
Fruits truncate-ovoid, about 8 mm. in diameter, rim rounded or flat-topped, 
not broad, valves 3 or 4, moderately exsert.
