Variety glauca, Maiden. 

 Western Australia. 



This is the ordinary glaucous or Gold-fields form of E. oleosa, known as 

 " Morrel." Specimens collected by me about 70 miles north of Kurrawang and 

 also at Kalgoorlie, September, 1909, may be taken as the type. See fig. 8, PI. 66. 

 Comet Vale (J.H.M.). See fig. 9, PL 66. 



Grounds of Kalgoorlie Hospital (Dr. J. B. Cleland). 



Coolgardie (R. Helms, C. L. Webster). 



" Tree 50 feet high, bark rough, greyish and persistent at base of trunk, 

 smooth and whitish upwards. Stamens sulphur yellow. " Morrell." "Blackbutt" 

 of Gold-fields," near Kanowna and Kurrawang (W. V. Fitzgerald). 



Dep6t Hill, Elder Exploring Expedition, 10th November, 1891 (R. Helms). 



" Small tree of 20-30 feet. A Mallee. Trunk with a rough bark, upper 

 branches smooth. Cowcowing (No. 1,001, Max Koch). 



" Arbor 25 m. alt (say 80 feet) cortice cinereo foliis glaucis ; floribus ochro- 

 leucis." Coolgardie (No. 5,470, L. Diels). 



Coolgardie pr. Kanowna (No. 1,703, L. Diels). Both these specimens were 

 referred to var. longicornis by Dr. Diels. 



Tammin (L. Diels, No. 2,854) is glaucous, but the buds and fruits are smaller 

 than those of the type. See fig. 6, PI. 66. 



The following specimens vary somewhat from the type, chiefly in being less 

 glaucous : — 



Coolgardie (E. Pritzel, No. 916) ; East of York (L. Diels, No. 5,018) ; 

 Sand Plains, Watheroo, Victoria District (A. Morrison) ; Port Gregory (L. Diels, 

 No. 5,718) (see fig. 7, PI. 66) ; Sand plain, Ebbano, east from Mingenew (A. 

 Morrison). 



The following specimens illustrate the confusion which has arisen between 

 E. oleosa, F.v.M., and E. decurva, F.v.M. 

 A. Copies of labels in herb. Melb. in Mueller's handwriting : — 



(1) (Eve. oleosa, E.M.) Eucalyptus decurva (Bth part, non), Ferd. Mueller. 

 South West Bay (Antherae globosae). (E. oleosa, var.) 



(2) (Euc. oleosa, F.M.) Eucalyptus decurva (Bth part, non), Ferd. Mueller. 

 Western extremity of the Great Bight, W.A. 



The specimens are oleosa, var. glauca. The words in brackets were written 

 later than the other words. The letters " Bth " of course stand for " Bentham." 



B. Bentham has two determinations of Drummond's No. 186 (5th Coll.). 

 See fig. 15, Plate 66 :— 



(1) E. uncinata Turcz., var. rostrata, Benth. (B.F1. iii, 216). 



(2) E. decurva, F.v.M., or rather Benth., non F.v.M. (B.F1. iii, 249). 

 I have seen the specimens, and they are identical.
