80-100 feet high, stems 3—1 feet in diameter, bark grey, suberous, slightly ribbony 

 at tips of branehes, the sap-wood yellow, centre red, darkening with age, interlocked 



in grain; fruits tubular, valves decidedly valvate, • arranged (mostly) in threes, 

 suckers glaucous, stems round, slightly angled. Used largely for sleepers. Bunda- 

 noon (J. L. Boorman). " White Box," very straight and some large ; rough bark 

 and clean limbs. Bundanoon (A. Murphy; ; 1 miles west of Bowral (11. H. Cambage 

 and J.H.M.). " Black Box," near bridge at Colo Railway Station (J.H.M.) ; Colo 

 (E. Cheel) ; Hill Top, Box Knob. The type (J.H.M.); The Oaks, Picton to Burrago- 

 rang (R. H. Cambage) ; The Peaks, Burragorang — most westerly locality recorded 

 (R. H. Cambage). "Soft White Box," Tillowrie, Milton (it. H. Cambage;; 

 Robertson, top of Macquarie Pass (J.H.M.) ; Dapto and Mount Kembla (R. H. 

 Cambage) ; Bulli Pass (R. H. Cambage and J.H.M.). 



Putty, south of Singleton (A. C. Barwick, per R. T. Baker). 



" It grows in considerable quantity near here. I have measured a tree, and 

 find that at 1 feet from ground the girth is 11 feet ; at GO feet the girth is 8 feet 

 10 inches ; the main limbs start at a height of SO feet from the ground. There 

 are much larger trees growing near, but I found it easier to obtain the measure- 

 ments from the fallen one. I have not noticed this Eucalyptus growing in the 

 district, except on the western slopes (in scrub) of Mount AYoollooma, in Forest 

 Reserve 10,222, Parish of Belltrees, County of Durham, Land District of Scone."

AFFINITIES. 



1. With E. goniocalyx E.v.M. 



The juvenile foliage of E. goniocalyx presents considerable similarity to that 

 of 17. quadrangulata, differing chiefly in the greater breadth and shorter length of 

 the former. The similarity of the mature foliage of the two species is uumistakable, 

 and extends even to the margins ; very large leaves have not, however, yet been found 

 in E. quadrangulata. The shape of the fruits is, however, quite different, while 

 E. quadrangulata is a Box and E. goniocalyx a Ribbony Gum. 



2. With E. nitens Maiden. 



The relations of these two species appear to be close. The rough bark of 

 E. quadrangulata extends further up the stem, and it appears to be a larger tree. 

 The buds of E. quadrangulata are more globular, and the fruits are broader at the 

 orifice (frequently more so than depicted at fig. 6, Plate 103), while the valves are 

 more exserted. 



In E. nitens (see Plate 81) the buds are more angular, narrower and more 

 elongated, the operculum being only half as long as the calyx-tube. The fruits are 

 ovoid, have a small orifice, and the valves are rarely exserted. In E. quadrangulata
