454 EUCALYPTS OF THE COUNTY OF CUMBERLAND, 



varieties of E. stellulata (Sieb.), viz. var. an^tistifoUa with, narrow 

 tliick leaves scarcely showing the venation, and var. microphjlla 

 wliich does not show any venation. This last variety is sometimes 

 mistaken for E. stricta, another shrubby species with fibrous bark 

 Mr. Bentham, who had the opportunity of examining the 

 specimens of Sieber, A. Cunningham, and the writer, distinguishes 

 E. stricta from the others by its anthers, Those referred to E. 

 stellulata and E. ohtusifiora have reniform anthers, the cells 

 divergent, and confluent at the apex, whilst the last has anthers 

 with distinct parallel cells, opening at first in round pores which 

 extend into oblong slits. In the sixth Decade of his Eacalypto- 

 (jrapliia, Baron Mueller expresses a somewhat different opinion. 



Section II. Hemiphloi^e. 



I. E. Sieleriana (F.v.M.), is the same as E. virgata (Sieber), 

 the name having been changed by Baron Mueller, as it is only 

 under exceptional circumstances, that the tree is reduced to a 

 virgate or twiggy state. This species passes for one of the 

 ^'Blackbutts" near Sydney, but on the Mountains and near 

 Berrima, it is called "Mountain Ash," The butt of the tree is 

 covered with a dark- coloured, deeply furrowed bark, similar to 

 that of Iron Bark, but not so hard and resinous, whilst the 

 branches are similar to those of the White Grum fE. ImmastomaJ . 

 As already noticed, there is a great similarity between E. 

 Sieleriana and E. hcemastoma, and to an ordinary observer, they 

 seem to differ only in bark and wood. An examination of Baron 

 Mueller's excellent figures will show how nearly they approach 

 each other. In the stunted form, in which E. Sieheriana appears 

 near the coast, the wood is not valued, but, according to Sir W. 

 Macarthur, " it is much valued for rough purposes in districts 

 where the better sorts of timber are not produced." He adds 

 "this species usually occupies rough, rocky sites, and seems to 

 form a link between the division of Iron Barks and that of Gums." 

 This tree in the Southern Districts rises sometimes to 120 feet,
