EUCAL YPTUS. 181 



3. E. nacrorrhyncha, P.M. Leaves elongated, equally green ; 

 umbels solitary; calyx-lid concavely attenuated, sharply pointed; fruits 

 below hemispheric, border convex, emersed, valves much exserted. 



4. E. pauciflora, Sieb. Leaves elongated, thick, shining, equally 

 green, veined longitudinally ; umbels solitary, lid hemispheric ; fruits 

 truncate-ovate, border of orifice depressed, valve? enclosed. 



5. E. amygdalina, Lab. Leaves thin, equally green; veins not 

 much spreading, oil-dots copious, transparent ; umbels solitary, flowers 

 small, lid almost hemispheric ; fruits truncate-ovate, border depressed, 

 valves enclosed. 



E. amygdalina regnans. Var. i. Lid hemispheric, pointed, fruit 

 obscurely speckled and cut off flat on top as though shaved, fruit and 

 flowers small ; bark persistent, rough ; foliage light green ; leaves thin. 



Var. 2. Lid hemispheric, pointed ; fruit scarcely speckled ; valves 

 in slight depression ; top of fruit not flat and uniform ; fruit and flowers 

 much larger than above ; bark smooth, decorticates ; foliage dull green. 



Var. j. Lid hemispheric, pointed ; flowers and fruit larger ; bark 

 smooth, decorticates ; foliage bluish green, often with bluish bloom. 



Var. 4. Leaves narrow ; lid hemispheric, flat no point purple 

 or red spot on center of lid ; fruit regularly speckled, valves in well 

 defined, slight depression ; fruit and flowers between the two sizes ; bark 

 apparently persistent and similar to that of what we identify as Eucalyp- 

 tus punctata, somewhat suggestive of bark of Eucalyptus tereticornis ; 

 foliage dull, dark green and leaves very narrow. 



Var. 5. Similar to above except fruits and flowers smaller and 

 grows like bush. 



Var. 6. Similar, except bark smooth, decorticates ; large tree ; pep- 

 permint odor present in all far strongest in regnans. 



Leaves in last three very narrow, dull, deep green, thickish and gen- 

 erally slimy on both sides. 



E. ligustrina, DC. Prod. iii. 219, described from Sieber's specimens 

 n. 617, which I have not seen, is probably this species. 



Var. radiata. Leaves rather broader, 3 to 4 in. long. Flowers 

 usually more numerous, sometimes near 20 in the umbels. Fruit almost 

 pear-shaped. E. radiata, Sieb. in DC. Prod. iii. 218 ; DC. Mem. Myrt. 

 t. 7. Chiefly in N. S. Wales, Sieber.n. 475, and others ; Bent's Basin and 

 Nepean rivers, " White Gum," with a smooth bark, Woolls; South of 

 Argyle, A. Cunningham, but also in Victoria and Tasmania passing into 

 the ordinary form. 



Var. nitida. Leaves broader and more rigid. Peduncles and pedi- 

 cels shorter. Flowers rather longer. E. ambigua, DC. Prod. iii. 219 ? 

 from the diagnosis taken from Labillardiere's specimen. E. nitida. 

 Hook. f. Fl. Tasm. i. 137. t. 29. In the dried specimens this variety 

 appears to pass into the variety elata of E. Risdoni.
