Hab. On the elevated tablelands of tbe interior of Tasmauia, especially in the neighbourhood of 

 tke lakes (Guim. No. 1084, 1080, 1082). 



As is the ease with otker species of tkis most difficult genus, no dependence can be placed on tke 

 size of any of tke parts or on tke form of tke leaves. Tke branehlets are slender, terete, nearly smootk, 

 tke younger very glaucous. Tke leaves, wkick seldom exceed two inches in length, vary between linear- 

 lanceolate and oblong, but are sometimes broadly ovate, with a mucro; tkese broader leaves frequently 

 terminate tke branckes. Tke peduncles are generally axillary, sometimes lateral, but always solitary, 

 and never more tkan three-flowered, from 2-4 lines long, stout and patent. Cupulae exactly turbinate, 

 sessile or generally shortly pedicellate. 1!-21 lines long, covered with fine glaucous bloom. Operculum 

 less than half the lengtk of tke cupula, hemispherical, tapering on the very summit into a short, stout, 

 erect mucro. Stamens bright yellow. Fruit elliptical, turbinate, broad at the base. 2-3 lines long, about 

 two-thirds broad or rather more, mouth slightly contracted. (op. cit.) 



it is most usually known as " Cider Gum : ' for the reason explained below 

 p. 107. It is also known as " Swamp Gum" because it occurs in swampy places at 

 high elevations. 



Hooker later describes it in his " Flora of Tasmania " (" Botany of the Antarctic 

 Voyage ") 1, 134 (with t. 27) in the following words : — 



Eucalyptus Gunnii (Hook. fil. Loud. Jouru. Bot. iii, 499); arbor parva, ramulis floribusque glaucis, 

 foliis alternis petiolatis ellipticis ovatis oblongis lanceolatisve acutis acuminatis mucronatisve. pedunculis 

 3-floris petiolo subicquilongis. calvcibus turbinatis breviter pedicellatis. operculo latiusculo conico acuto 

 calyce subbreviore, capsula, obovato-oblonga ore hod incrassato, valvis immersis. (Gvnn. 1080. 1082, 

 1084, L963.) (Tab. xxvii.) 



Hab Abundant in alpine districts, elev. .'i 1.000 feet, often forming small Eorests in marshy | 

 k<.. Gunn, &c. (Fi. Nov.) (r.r.j (Cider-tree). 



Distrib. Alps of South-western \ustralia. Muslin. 



A very common l>m singularly variable small tree, 20 30 feet high, sparingly, irregularly branched, 

 with smooth bark and glaucous foliage. Iiecoming shining in old plant,-. Sometimes, however, solitary 

 tree, ruav be found of mucli greater size, and jo like /;. viminalis that without fruit it is difficult to 

 distinguish it from an alpine form of that species. Lraves .seldom above "2 inches long, of all shapes, from 

 oblong or almost orbicular to narrow-lanceolate, petioled, ven coriaceous Peduncles about -^ long .is the 

 petioles three-flowered. Calyi obconic, sessile or shortly pedicelled, sometimes obscurely constricted
