It differs from M. Leucadendron in the shape, length and 

 texture of its leaves, flowering spikes, and perhaps smaller fruits. 

 Chemically, it is quite distinct, and differs in similar characters 

 from M. Maideni described in this paper. 



M. minor Sm., has thinner and narrower leaves, and longer 

 spikes, and produces " Cajeput" oil of commerce. M. viridiflora 

 Gsertn., (J/. Cunninghamii Schau.) and M. saligna have very 

 much longer and broader leaves, and white woolly tomentum on 

 the inflorescence. 



M. lanceolata has leaves under 1" long, a white woolly in- 

 florescence, and a constant trinerved venation. 



It is dedicated to my colleague, Mr. H. G. Smith, F.C.S.. 

 Assistant Curator of the Technological Museum, who has now done 

 so much organic research work on the Australian flora. 



Angophora ochrophylla, sp.nov. 

 A large, spreading tree, with a very rough, " woolly " thick 

 bark, glabrous in all its parts, with willowy, filiform branchlets. 

 Inflorescence in large, terminal, loose, delicate corymbs. Leaves 

 opposite, on short, slender petioles, lanceolate, slightly falcate, 

 occasionally oblique, texture thin, almost membranous, pale 

 yellowish or ochreous in colour, 3 to 5 inches long. Flowers 

 rather small, on exceedingly slender or almost filiform peduncles. 

 Calyx 1 line long, teeth acuminate, ribs of equal prominence. 

 Fruits on filiform pedicels up to 6'" long, 3-4"' wide, 2-3"' in 

 diameter. 



Arbor altitudinem 60-100' attinens. Cortex trunci squalido- 

 vel fusco-canus, rugosus, rimosus, persistens. Folia circiter 3-5" 

 longa, breve petiolata, lanceolata, obliqua, et evidenter tenuiora 

 quam in A. intermedia. Flores in corymbis. Fructus 2-3-4"' longi, 

 truncato-ovati. 



Hab. — Myall Creek, Bingara(C. F. Laseron), Woodburn (W. 

 Bauerlen). 



Remarks. — On a cortical classification, this Angophora falls 

 into the rough barks, but yet it has a bark quite unlike any other 

 described species of the genus. In field-facies, it much resembles 

 Eucalyptus Bridgesiana, the bark especially so; in fact, the barks 

 of the two trees are identical in character.
