" 8 Mile Spring on to Tanumbirini (near creeks and springs). Crimson filaments. 

 Stem like Blood-wood. (Appears to be same species as white- flowering form No. 810.) " 

 (G. F. Hill, No. 809.)" 



" No. 810. 8 Mile Creek on to Tanumbirini (tree similar to 809). Cream 

 flowers. (G. F. Hill.) 



Both were collected on the same day, 26th March, 1912, and are identical, 

 except in regaid to the colour of the filaments. E. ptychocarpa is therefore to be added 

 to the list of species with filaments of two colours. 



AFFINITIES. 



1. With E. miniata A. Cunri. 



In the original description, Mueller says that the trunk of E. ptychocarpa, so 

 far as the bark is concerned, holds an intermediate place between the Stringy-barks 

 and the Boxes. He amplifies this in the following passage : — 



" With a greyish, wrinkled, everywhere persistent, somewhat fibrous bark, thus 

 fluctuating between the Stringybark and so-called Box trees, though in cortical 



characters perhaps nearest to E. hcmiphloia and E. albens, but " 



(" Eucalyptographia. ") In his classification of barks he puts it with the Pachyphloise. 



Mr. W. V. Fitzgerald (MSS.) says it is "a tree up to 40 feet, trunk 15 feet, 

 diameter 2 feet, bark persistent on stem and branches, dark-coloured, rough, soft and 

 flaky, timber red, soft and very porous." On the evidence.it is not proper to put 

 E. ptychocarpa with the Pachyphloise (Stringybarks). 



It is difficult, in exceptional cases, to describe clearly the bark of a Eucalypt. 

 That of E. miniata I have tried to describe at p. 37, Part XXII. While I do not say 

 that it is the same as that of E. ptychocarpa (a bark I have not seen, except in a very 

 young tree), the fact that E. miniata is sometimes called (with others) "Woollybutt" 

 and "-Stringybark " shows that, at least as regards the barks of the trunks of mature 

 trees, the two species have some resemblance to each other. 



A character hitherto unrecorded is that some of the young or intermediate leaves 

 are slightly peltate. This is consistent with the suggested Corymbosse affinity. 



Bentham says: 'The fruit (of E. ptychocarpa) somewhat resembles that of 



E. miniata, but the venation of the leaves and the inflorescence are quite different." 



(B. Fl. iii, 255.) 



Mueller, later, observes : " FvomE. miniata it is far more distant (than E. Abergiana) in its not 

 scaly-friable bark, which does not separate from the main branches, in the leaves being not of a pale and 

 dull-green on both sides, besides of thicker consistence, much larger and proportionately also broader, without 

 any translucent oil-dots, in the absence of stomata on the upper page of the leaves ; further, in the umbels 

 not solitary nor lateral nor axillary, in larger flowers and conspicuous development of flower-stalklets, 

 in fruits often smaller (although similarly shaped and ridged), and in the seeds provided with a long appendage 

 (those of E. miniata being quite exappendiculate). (" Eucalyptographia," under E. ptycJiocarpa.)
