60 A RESEARCH ON THE EUCALYPTS OF TASMANIA 



EUCALYPTUS TAEN1OLA (gp. nov.). 

 (Plate III.) 



Historical. This appears to be the first actual scientific 

 record of this Eucalyptus. 



Remarks. The specimens upon which this species is 

 founded were obtained by Mr. L. G. Irby at St. Mary's 

 Pass, Tasmania, where it was found growing amongst trees 

 of K. riryata, and E. amiigdalimi , LabilL, and from 

 which he states the species is easily differentiated in the 

 field from its congeners. The bark is finer-checked than 

 E. rirgata, running more closely to the " Peppermint " 

 bark in texture than the latter species. 



The leaves, both " sucker " and normal, are much nar 

 rower than those of K. rir<j<it<i, and of a different appear- 

 ance altogether. They are long and linear, varying greatly 

 in length on the same tree, being from 4 to 11 inches 

 long 7 to 8 inches long being common. It is on the rib- 

 bony appearance of the leaves that the specific name is 

 founded. 



The fruits, however, are almost identical with those of 

 E. rtrf/ftta, and yet the general appearance of the tree is 

 more like that of K. amygdalnm (L. G. Irbv). 



Si/xfrttnifir Description. A tree about 40 to 50 feet 

 high, and 2 feet in diameter, with a " Peppermint " bark. 

 " Sucker " leaves linear, lanceolate, straight, 4 to 6 inches 

 long, ^-inch wide, opposite or alternate. Normal leaves 

 narrow linear to linear, lanceolate, up to nearly 1 foot 

 long, thin, venation not pronounced, but best seen in 

 larger leaves, lateral veins very oblique, intramarginal 

 vein removed from the edge. Peduncles axillary, but 

 (through the falling off of the leaves) the infloresence 

 sometimes appears paniculate. Flowers few in the head. 

 Calyx pyriform ; operculum small, compressed, slightly 

 pointed. 



Fruits pear-shaped, ^-inch long and J-inch wide, taper- 

 ing into a short pedicel, rim countersunk, valves not 

 exserted . 



Arbor medoicra, attitudinem 40-50' attinens ; 

 ramusculi teretes, graciles. Cortex trunci in 

 laminis duris, similiter " Peppermint " generis. 

 Folia alternata, semi-coriacea, angusta lanceo- 

 lata v. lineata (taeniola) 12" longa J" lata ; 

 venis parum insignis acutis obhquis, vena 

 peripherica a folii margine conspicue remora. 

 Pedunoulis axillaris, solitariis 5-9 floris pedi-
