AND THEIR ESSENTIAL OILS. 39 



(Rodway, " Fl. Tas.," p. 57). The herbarium material 

 generally differs in several respects from all those species, 

 and so we have been induced to record it as a new species. 

 The buds are in threes, just as in E '. viminalis, and that 

 is the only resemblance to this species in the inflorescence. 

 The fruits and buds are distinct in shape from those of 

 E. globulus and E. Maideni, and what is of greater sys- 

 tematic importance, the leaves of both forms match neither 

 of these. 



In the angularity of the buds are traces of a resemblance 

 to E. goniocalyx, but as these mature in the fruit the 

 angles disappear, but traces remain and form distinct con- 

 vex ridges extending from the rim to the base, and as 

 one is generally much more pronounced than the others, 

 it is upon this character that the specific name is bestowed. 

 Systematic Description, A tree attaining a height of 

 30 to 40 feet and a diameter of 12 inches, with a flaky 

 bark at the butt. Sucker leaves, sessile, opposite, oval at 

 the first, the lower pairs nearly always so, up to 2 inches 

 long and 1 inch wide, then cordate, acuminate, up to 3 

 inches long and 1J inch wide. Normal leaves lanceolate, 

 falcate up to 9 inches long and 1 inch wide, subcoriaceous, 

 occasionally shining on the upper surface. Venation dis- 

 tinct, lateral veins moderately oblique, intramarginal vein 

 removed from the edge. Branchlets in sucker growth 

 terete, but angular at first on the others. Peduncles 

 axillary, flattened, short, thick, J-inch long, three sessile 

 flowered. Calyx, compressed, angular, under J-inch long; 

 operculum conical. 



Fruit hemispherical, J-inch in diameter, shining, rim 

 thickened, convex with a very narrow groove below it, 

 valves well exserted. 



Arbor altitudinem 40' attinens, ramulis validis 

 superne quadrangulatis. Folia opposita sessile 

 oval v. cordata acuminata 2-3" longa, v. fal- 

 cato-lanceotata 9" longa, 1" lata, obscure pen- 

 nivena, vena peripherica a margina remotius- 

 cula. Pedunculi axillari, brevi 3'" longi, com- 

 planati 3 flori ; calyx tubus compressus circiter 

 2'" longus cum operculo conico obtuso. 



Fructus hemispherici, vitrei unialata, 6'" 

 longi; margo orassus valva exserta.
