 lato-ellipticis ad ovatis, petiolatis 3-5-8-5 cm. longis, 3-5-6-5 cm. latis; venis 

 mediocriter distinctis, vena peripkerica a margine remota, venis lateralibus remotis e

 lato-lanceolatis 7-5 cm.-12 cm. longis 1-5-3 cm. latis; venis obscuris e costa 45° 

 orientibus; inflorescentia axillari, pedunculis compressis floribus breviter pedicellatis 

 5-9 capitulo; alabastris glaucis clavatis; operculo hemispherico calycis tubo turbinato 

 breviore; fructibus pyi'iformi-cylindraceis truncatis 10 mm. longis, 6 mm. latis 

 4-loeularibus, valvis insertis. 



A slender white gum, ribbony at the butt, 20-25 feet high, with a trunk 4 inches 

 in diameter. Wood very tough, a little brown at heart. (Only one clump was seen, 

 and a fuller note will be found at p. 372.) 



Juvenile leaves broadly ovate to ovate-elliptical, with a rather long, semi-terete 

 peduncle, 3-5 to 8-5 cm. long, 3-5 to 6-5 cm. broad, slightly glaucous (the somewhat 

 compressed internodes very glaucous), rather thick and rough, with numerous slightly 

 raised oil-glands, and the minute reticulate veins. Venation moderately distinct, 

 intramarginal vein distant from the edge, lateral veins rather distant, approximately 

 forming an angle of about 45 degrees with the midrib; midrib prominent beneath, 

 indistinct above. 



Intermediate leaves slightly glaucous, broadly cordate-lanceolate to obliquely 

 lanceolate, a few rounded-deltoid, 5-9 cm. long, 5-7-5 cm. broad, the petiole terete, 

 sometimes exceeding 2 cm. long. Venation moderately distinct, intramarginal vein 

 somewhat wavy, and here and there 3-4 mm. from the edge, lateral veins making an 

 angle of about 45-50 degrees with the midrib. 



Mature leaves thick, pale green, dull, narrow to broad-lanceolate, 7-5 to 12 cm. 

 long, 1-5 to 3 cm. broad, venation obscure, the intramarginal vein usually confluent 

 with the edge, lateral veins obscure, making an angle of about 35-40 degrees with the 

 midrib. 



Inflorescence axillary, the common peduncle compressed, gradually expanding 

 upwards, 10-15 mm. long, supporting a head of 5-9 flowers on short, thick pedicels. 

 Buds glaucous, clavate, including the pedicel 11 mm. long; operculum hemispherical, 

 often with a small umbo, many times shorter than the calyx -tube, wrinkled and more
