E. Risdoni, its var. elata, and my E. obliqua, var. alp'ma fdelegatensisj, formed one 

 grand trimorphic species. The strong, sweet odoixr of the trees of E. Risdoni, var. 

 elata, in the forest very closely resembles that of E. obliqua, var. alpi- a. Some 

 Gum-top Stringybarks are undoubtedly near typical E. obliqua. This form {alpiua) 

 of obliqua is found in alpine situations in lasmania, Victoria, and southern New 

 South Wales. Following are some of the localities represented in the National 

 Herbarium, Sydney : — 



Tasmania.

 Marlborough (in Gunn's Herbarium, but collected by J. D. Hooker) ; " Gum-top 

 Stringybark," East Mount Field; Guildford Junction (R. H. Cambage) ; Parattah 

 and Russell Falls River (T. Stephens).

PLATE 29. 



la. Twig bearing buds; 1//, bud, just opening; Ic, flowers; Id, fruits, all facsimiles of Labillardiere's 



original drawing of E. amygdalina in PL Nov., HolL, t. 1-5-1. [N.B. — The fruit is not perfectly 



ripe.] le, anthers from flowers from Bellerive, Hobart, absolutely similar to those of the type. 

 In. Twig, with buds and flowers, 26, fruits ; of Gurm's No. 25. (See Hooker's Fl. Tas.) It is absolutely 



identical with Labillardiere's specimen. Gunn's No. 2.5 came from New Norfolk, but the form 



is common in Tasmania. 

 3. Juvenile foliage of E. amyijdalina, from Hobart (L. Rodway). Note that the young stem is glandular, 



and that the leaves are sometimes in threes 

 4«. Juvenile leaves; 46, buds and mature leaves ; 4c, fruits, from Blackheath, Bhie Mountains, New South 



Wales, which absolutely match type specimens of E. radiata, Sieb. (See p. 153.) 

 5a. Juvenile leaves ; 56, buds ; 5r, fruits, of a common New England form of E. ainytjdaiina. Very close 



to, if not identical with, E. radiata, Sieb. (See page 161.) Juvenile leaves broadish. (See No. 9.) 

 6rt. Buds, with leaf ; 66, fruits, of typical E. radiata, Sieb., drawn from Ft. .Mixto, No. 604. TIic fruits 



are not perfectly ripe. The drawing {Mem. Myrl.), No. 2, pi. 30, shows the fruits of E. radi'ita 



more pear-shaped than I have ever seen them, and nearer the shape of those of var. radiata. 

 la. Juvenile foliage ; lb, nuiture leaf; 7c, fruits, from Wingello, New South Wales (J. L. Bonrman). A 



form intermediate between var. numerous and var. iiitida. (See p. 163.) 

 8rt. Juvenile leaves ; 86, fruits, from Munendel Hill, Victoria (A. W. Howitt). E. ronyyd'i/ina, with 



broadening juvenile leaves. 

 !). .Juvenile leaves, Walhalla, Victoria (A. W. Howitt). E. ami/ydalina, with still broader juvenile leaves.
