426 J. H. MAIDEN. 
The name Porcupine Stringybark is also applied to it for 
the same reason. 
2. EUCALYPTUS KIRTONIANA, F.v.M. 
[Syn. E. patentinervis, R. T. Baker. | 
Following is the history of Mueller’s species, beginning 
with the two published references made by him. 
1. ‘In the Illawarra district occurs a tree which attracted great 
attention in India, not only because of its rapid growth, but also 
as it proved the best species there to cope with the moist tropical 
heat. This tree has been cultivated at Lucknow by Dr. Bonavia, 
who recorded that it attained in the best soil twelve feet in two 
years; it was there considered to belong to Z. resinifera. It 
differs, however, from that species in having the leaves of equal 
colour on both sides with more prominent veins, the intramarginal 
veins more distant from the edge; thus in venation, as also in 
odour of foliage and fruit, the tree in question approaches £. 
robusta, but its fruit is certainly similar to that of ZH. resinifera, 
wanting, however, the broadish outer ring around its orifice 
characteristic of the typical Z. resinifera, while the lateral veins 
of the leaves are not quite so transversely spreading as in either. 
If really specifically distinct, the tree might be named £. Kir- 
toniana in honour of its discoverer.” (Mueller’s ‘‘EKucalypto- 
graphia under Z. resinifera. ) 
2. “A quick growing tree, rare in the Illawarra district, which 
at Lucknow attained a height of 45 feet in 10 years, and which 
as a species or variety I distinguished as #. Kirtoniana, is in 
flowers and fruit nearer to #. resinifera than to £L. robusta, but 
has the leaves of almost equal colour on both sides, thus far, and 
also in shape, more resembling those of LZ. tereticornis, while the 
bark, unlike that of £. saligna, is persistent. The stomates of 
E. Kirtoniana vary on the upper side of the leaf between 33,000 
and 43,000, and on the lower page from 95,000 to 166,000 on a 
square inch, this great fluctuation being attributable probably to 
the age of the tree. It is particularly noticeable on account of
