TWO NEW SPECIES OF EUCALYPTUS. 455 
Bark.—Thin and smooth to the ground, sometimes rib- 
bony, ‘5-2 mm. thick, slaty to greenish in colour. 
Timber.—Brown towards centre, tough. 
Habitat—Near Pokolbin, a quarter of a mile west of 
portion 146, Parish of Rothbury, County of Northumberland, 
New South Wales. 
This species is a Mallee growing on the side of a hill 
amongst Hucalyptus siderophloia Benth., EH. maculata 
Hook., Callitris calcarata R. Br., Casuarina Luehmanni 
R. T. Baker, and C. stricta Ait. The specific name is in 
allusion to the dwarfed habit of the tree. 
Seedlings—Hypocotyl red, erect, glabrous. 
Cotyledons slightly emarginate, 1°7 mm. long, 5 mm. 
broad, lobes oblong-obtuse, upperside green, underside red, 
glabrous; petiole 2mm. long. - 
Seedling foliage opposite for two or three pairs, entire, 
glabrous, oval-lanceolate to ovate and ovate-lanceolate, 
obtuse. First pair up to 1°4 cm. long, 7°5 mm. broad, 
upperside green,underside red to purple, petiole 2 mm. long. 
Second pair up to 3 cm. long, 1°8 cm. broad, underside red 
to purple, petiole 5 mm. Third pair up to 4°7 cm. long, 2°4 
cm. broad, underside at first reddish-purple, becoming pale 
green, petiole up to 7 mm. 
Stems red. 
The seeds germinated 125 years after being gathered. 
Plants, when about 6—8 inches high, developed nodules or 
swellings about the axils of the cotyledons, which had 
fallen. 
Affinities. 
Its closest affinity appears to be with EH. dealbata A.Cunn., 
from which it differs in bark and timber, as well as the 
texture of the leaves, and the position of the intramarginal 
vein. The seedling foliage is also different.* H. dealbata
