Varieties. 



1. acuminata n. var. 



2. brevirostris F.v.M. 



3. borealis Baker and Smith. 



I do not think that either (2) or (3) is valid. 



1. Var. acuminata n. var. 



E. acuminata Hook, in Mitchell Journ. Trop. Austral. 390. 



Description. — " Foliis alternis petiolatis lanceolatis longe acuminatis subaristatis penninerviis glaucis 

 retieulatis, nervis lateralibus a inargine remotiusculis, floribus umbellatis (4-6 floris), umbellis peduneulatis, 

 calycis tubo heniispherico in pedicellum gracilera attenuato, calyptra conico acuminato calycis tubum 

 superante." 



Bentham (B. Fl. hi, 241) states that this form approaches the variety brevirostris 

 F. v. M. of E. tereticornis. I do not know what this is, but it is not similar to E. rostrata 

 var. brevirostris F. v. M. 



I have examined the type, which is " Nov. 20, 1846, No. 435. ' Yarrow ' 

 (Yarra) of the blacks. Sub-tropical New Holland. Lieut. -Col. Sir J. L. Mitchell. 

 Eucalyptus acuminata Hooker, 472." Herb. Cant, ex herb. Lindl. 



It was collected on the left bank of the Mooni (now called Moonie) River, which 

 would be somewhere between Dalby, and going south and west to near the New South 

 Wales -Queensland border. 



Mr. J. L. Boorman has collected the same form at Springsure, which is south 

 of Emerald, on the Rockhampton (Queensland) line. His note is "'River Red Gum.' 

 Large trees, sound, and of massive growth on the river flats. The timber is thought 

 much of for building purposes of all kinds." 



It also occurs at Baradine Creek, and Wongan, between Baradine and Pilliga 

 (Dr. H. I. Jensen), and other parts of the Pilliga district, N.S.W. Its range requires 

 to be worked out. It does not appear to be a common form. 



I have two specimens which seem to come nearest to var. acuminata. Both 

 are in bud only, and finality cannot be reached with them without additional material. 



(a) Pointed ovoid buds with commissural line present. Near Stannary Hills, 

 North Queensland (Dr. T. L. Bancroft, No. 172). 



(b) Buds more pointed and nearer var. acuminata than (a), Bullock Creek, 25 

 miles north-west of Trundle, N.S.W. (R. H. Cambage, No. 1,014). 



2. E. longirostris F.v.M. ex Miq. in Ned. Kruidk. Arch, iv (1856), 125. 



f3 forma brevirostris Mull, rostro breviore; see p. 66. Ad Glenelg River (F.M.). 



Glenelg River, Western Victoria. I see no difference between this and normal 

 rostrata. One or two of the buds may be a little stumpy, but others are quite normal. 

 The type of E. longirostris F. v. M. (which I have not seen) probably had an operculum 

 longer than that of E. rostrata, and therefore var. brevirostris would appear shorter by 

 comparison. See fig. 8, Plate 137.
