Luehmann's label is " N. of McDonnell Range, Plenty River, Marshall River, 

 Milne River, Lake Nash (Lieut. Dittrich, 1886)." Mueller labelled it E. pachyphylla. 



Plenty River near S. lat. 23, unites with the Sandover River to form the Marshall 

 or Hay River (N.T.). The Milne River runs into the Herbert River near the Northern 

 Territory-Queensland boundary in 21° S. lat. Lake Nash is near the Northern 

 Territory-Queensland border near 21° S. lat. 138° long. The material consists of a 

 few loose buds and fruits, buds with pedicels on short peduncles, and with sharply 

 pointed opercula and sharp, almost winged ribs, sharper than figured in Plate 75 or 

 in the " Eucalyptographia." The fruits (fig. 6, Plate 171) sessile. (These fruits very 

 well match the sessile flowers figured in the " Eucalyptographia.") 



Queensland. 

 Labelled pachyphylla by F.v.M. : — ■ 



1. Sources of the Georgina River (Lieut. Dittrich, 188G). Flowers and buds only. 



2. Dense bushes, 10-15 feet high, Spinifex sand plains, 27 miles west of the Rankin 



River, lat. 20° 27' 24" :— 



(a) Flowers with short pedicels and moderately ribbed opercula very 



pointed. 



(b) Buds, with label (as above), but buds rather more pedicellate. 



Both (a) and (b) show how difficult it is to frame a character on the length of 

 the pedicel. They certainly connect with the Tanami specimens. 



The Georgina River of Western Queensland has its principal source in the Barkly 

 Tableland, and receives the Lome and Rankin's Creeks from the Northern Territory. 

 In the " New Atlas of Australia " (1886), the Rankin and the Lome are shown as the 

 same stream, in 20-21° S. lat., near the Queensland border. 



These Queensland specimens collected by Lieut. Dittrich in 1886, for Mueller, 

 were obtained near the Northern Territory-Queensland border, and on the same trip 

 as those collected by the same traveller and recorded under Northern Territory. 

 Arranging them geographically under two States is merely a matter of convenience. 



AFFINITIES. 



1. With E. alpina Lindl. 



"Near to E. alpina" (original description). (See Part IX, Plate 41, for E. 

 alpina.) The anthers of the two species are totally different. E. alpina is a rather 

 broad-leaved small tree of mountain tops of a restricted range in Victoria. The buds 

 and fruits of E. alpina may be described as warted ; the ridges, where present, are not 

 as well defined as in E. pachyphylla. The fruits are different, though sometimes 

 possessing a resemblance.
