EUCALYPTUS STEICTA. 



completely with the plant occurring at Black Heath, so far as leaves and ripe frnits are concerned. 

 Bentham refers it to E. obtusiflora ; but De Candolle's description and delineation (prodr. iii. 220, 

 and Memoir des Myrtace'es t. 10) indicate a species of the series Parallelantherse, the leaves of 

 which, according to an authentic specimen sent to the writer of these lines by Mons. Alphonse 

 De Candolle, are not very shining, show no large oil-pores, and have a very visible close and much 

 spreading venation, much like that of E. tereticornis. E. virgata, Sieber's No. 467, according to 

 an original specimen from Prof. Heurck of Antwerp, is a form with larger and more curved 

 leaves, with broader two-edged umbel-stalks, larger and more pointed calyces ; with this plant 

 Mr. Bentham combined a tall arboreous species, to which the name E. Sieberiana was given in 

 this work, although subsequently it became clear, that Sieber remained unacquainted with this 

 particular species, which is closely allied to E. htemastoma, and differs already from E. stricta in 

 smooth calyces with a more turgid tube, antherless outer filaments and flat-topped fruits, 

 irrespective of tall growth. But the real E. virgata does undergo a development in another 

 direction, enlarging to that startling state, which was distinguished as E. Luehmanniana, under 

 the impression at the time of discovery, that a remarkable new species was obtained, by which the 

 name of an able assistant, Mr. George Luehmann, was to be honored, who zealously aided the 

 author in many of the preliminaries for this moiiography. But subsequent sendiugs by Mr. Kirton 

 from Bulli proved, that this extremely luxuriant form passes into the normal one, the latter indeed 

 occurring at the same locality. The variety Luehmauuiana is characterized by thick sharp-angled 

 branchlets, which as well as the calyces and their stalks become bluish-white from waxy 

 exudations, has leaves attaining to many inches length and 1^ inch width, has broad compressed 

 almost wedge-shaped umbel-stalks, produces large longitudinally narrow-ridged calyces with lids 

 tapering to a long point, and forms large 4-6-celled fruits, the discal border of which becomes 

 much widened out between the calycine edge and orifice, so that the fruits attain a diameter of 

 rather more than half an inch ; leaves from adventitious shoots will assume occasionally an oval- 

 orbicular form. E. stricta in two of its cardinal characters approaches E. obliqua, sharing in the 

 granular roughness of the calyces and showing also a similar shape of fruit. Mr. Bentham, in 

 attributing very minute anthers to E. stricta, and placing it therefore in the series of Micrautheras, 

 may have had for dissection very young flowers only.
