The following specimens are indubitably within the Northern Territory. 



Moderately glaucous. Between Finke Eiver and MacDonnell Ranges (Lieut. 

 Dittrich in Herb., Melb.). Very glaucous, juvenile leaves only, north of MacDonnell 

 Ranges (Lieut. Dittrich, 1886, in Herb., Melb.). Very glaucous. Henbury station, 

 Finke River, 9th March, 1911 (G. F. Hill, No. 45). Very glaucous. 35 miles north- 

 west of Meyer's Hill, 2nd June, 1911 (G. F. Hill, No. 223). 



AFFINITIES. 



1. With E. perfoliata K. Br. 



" It is distinguished from E. perfoliata E. Br. (B. Fl. iii, 253) by smaller leaves, calyx-tube twice 

 as long as broad, the fruit many times smaller, not unceolate." (Original description.) 



" The concrescence of the leaves by pairs in all stages of growth occurs, as far as known, only in 

 E. perfoliata, if even in that rare and little known congener this coalescence should prove also unexceptional ; 

 nevertheless, it must be kept in mind that the RLsdonian variety of E. amygdalina (E. Risdoni Hook, f.), 

 and also E. uncinata, or a closely allied species (it is not clear what this species is — J.H.M.), when in 

 their stage of opposite leaves, occur also with some of them occasionally quite grown together into one." 

 (Eucalyptographia under E. garnophylla). 



E. perfoliata R. Br. is a very coarse species, with leaves and inflorescence very 

 much larger than those of E. garnophylla. The large urceolate fruit shows that the 

 former belongs to the Corymbosae. The two species are by no means closely related. 



In my paper " On two new Western Australian species of Eucalyptus," in Journ* 

 Nat. Hist, and Science Soc. of W.A., iii (1910), I have some notes on the connate and 

 petiolate leaf. Taking the list of species therein enumerated (and E. Perriniana F.v.M., 

 see Part XXVI of the present work can be added), we find that all species tend to the 

 elimination of the connate or petiolate leaf as development proceeds. 



2. With E. pruinosa Schauer and E. melanophloia F.v.M. 



" The exact affinity of this species can be best shown by the stamens (not known then — J.H.M.), 

 which will perhaps prove to be near E. pruinosa and E. melanophloia." (Original description.) 



Subsequently the stamens were found, and we have :- — 



" In the systematic arrangement it might find its place near E. pruinosa and E. melanophloia, from 

 both of which, irrespective of its stunted habit, it differs already in the above given notes of the union 

 of leaf-pairs, and the size and shape of the embryonate seeds, and besides in the longitudinal dehiscence 

 of the anthers." (Eucalyptographia under E. garnophylla.) 



In the absence of full herbarium material, it is not always easy to distinguisl 

 E. gamoplujlla from E. pruinosa. Compare Part XII, Plate 52 of the present work. 

 The former is rated as a shrub, at the same time it must be a big shrub with timber
