1902.— In Jouni. Roy. Soc. N.SAY., xxxvi, p. 319 (1902) I submitted the following 

 notes on classification: — 



1. Gums. — These timbers are short in the grain, dry to a brown or reddish colour, 

 (.rack radially in drying, have many gum-veins, and, as a rule, lack durability. Their 

 barks are smooth, and more or less ribbony. Examples : stellulata, coriacea, hecmastoma, 

 viminalis, Gunnii. They connect with the "Boxes" (Bastard), and also with the 

 smooth-barked members of the Jarrah Group. 



2. Mallees. — Examples : oleosa, Behriana, incrassata. This is a group based 

 on geographical considerations. They are arid country species, and connect the " Gums " 

 and "Red Boxes." 



3. Ironbarks. — These are fully described in my " Notes on the Commercial 

 Timbers of New South Wales." They consist of (a) True Ironbarks, viz., panicidata, 

 siderophloia, crebra, sideroxylon ; (b) Bastard Ironbarks, timbers very similar to 

 Ironbarks, but the barks belonging to the " Box " group. They consist of Boormani 

 and affirm; melanopJdoia (and perhaps microtheca) connect the two groups. 



4. Boxes. — These are tough, interlocked timbers, usually with fibrous bark on 

 the trunk, and may be subdivided into : — ■ 



(a) Pale. — Examples : hemiphloia, melliodora, Bosistoana, Baueriana, populijolia, 



quadrangidata, Cambagei (eheophora), goniocalyx, tesselaris, leucoxylon, coryno- 

 calyx (cladocalyx), globulus. 



(b) Red. — Examples : bicolor, microtlieca, polyanihema, odorata (should be brown), 

 fasciculosa. These two groups include some smooth barks or "gums," but 

 their timbers are provisionally classified with the " Boxes." 



(c) Bastard. — Examples : Stuartiana, pulverulenta, Macarthuri, aggregata. The 



timber of (c) is inferior and closely resembles that of the Gums. 



i 5. StringybarJc Group. — This includes a number of fissile timbers that pass into 



each other and may be subdivided as follows :— 



(a) True Stringybarks. — Examples : eugenioides, macrorrhyncha, capitellata, obliqua, 



Baileyana. 

 (/-) Blackbutts.— Examples : pilularis (which absolutely connects with the Stringy- 

 barks through its variety, Mueller iana), acmenioides. The most valuable 

 timbers of the group. 



(c) Peppermints. — Examples: aniygitiilina, regnans, dives, piperita; these timbers 

 have gum-veins and are altogether inferior in quality. 



Allied to these are: — 



6. Mountain Ash Group. — Fissile timbers usually pale in colour, and with bark 

 not so fibrous as the preceding. Example : Sicberiand. 



7. Tallow-wood and Spotted Gum. — E. microcorys and E. maculala, two valuable 

 pale-coloured timbers, sui-generis.
