112 ON THE EUCALYPTS OF N.S.W., PART VII., 



drical, and the valves are scarcely exserted. The bark is, how- 

 ever, more of an "Ironbark" in character except in the case of /. 



(c) is called "Bastard Box" or "Ironbark." It is found on 

 the Waterloo Estate near Upper Bankstown and St. John's 

 Park. 



(d) is " Bastard Box " or " Box." The trees are of large size, 

 the bark rough to the tips of the branches. 



(e) has a bark rougher than the preceding, but is otherwise 

 identical. 



(f) grows at Cabramatta and is called "Black Box" by Mr. 

 T. Shepherd. The bark is fibrous and persistent, "the wood 

 hard and bad for burning," according to the late Rev. Dr. Woolls. 

 Dr. Woolls, who had an intimate and extensive knowledge of the 

 Eucalypts of the colony, expressed himself to be much puzzled 

 with these trees, and marked specimens of this particular form 

 at one time as E. siderophloia and at another as E. paniculata. 

 The original specimens are in the Herbarium of the Sydney 

 Botanic Gardens and illustrate the difficulty that these supposed 

 hybrids have given rise to in times gone by. 



It will be seen how the above forms show different steps in the 

 gradation between E. hemiph/oia and E. sirferopldoia. A sus- 

 picion of a resemblance to E. sideroxylon is visible in at least one 

 of the specimens. The case is very different in E. affinis, which, 

 though partaking of some of the characters of E. hemiphloia var. 

 albens and E. sideroxylon, is pretty constant in its amount of 

 resemblance to each. The suggestion therefore that the trees 

 last described and marked b, c, d, e and / are hybrids has much 

 more force than in the case of E. affinis. 



In describing E. Bosistoana, Mueller (Aust. Journ. of Pharmacy, 

 Oct., 1895) included in it two trees, one the southern tree (a Bed 

 Box) with numerous valves and which is now generally recognised 

 as E. Bosistoana. He also included the Ironbark Box of Cabra- 

 matta, a very different tree. One of us drew his attention to the 

 matter and he promised to make the necessary amendment in the 

 description, but death overtook him before he could carry out his 

 intention.
