Arbor permagna ad 180 pedes alta, 1-6 pedes diametro nietrens; cortex stispis dense fibrosus atque inter- 

 textus; rami glabri; folia juvenilia opposita, angnsto-vel late-lanceolata, acuminata, sessilia nunc 

 amplexicaulia, parvuni glauca, 1-5-10 cm. longa, 9-30 mm. lata ; folia rnatura alternata. petiolata, angusto- 

 vel late lanceolata, tenuia, exsiccata, viridi-glauca, 7-17 cm. longa, 1-5-3 cm. lata; pedunculi axillares 

 fulcientes 9-21 parvos flores; gemmae pedicellatse, clavatae vel rostratas; antherse reniformes; capsulee 

 hemisphaericse vel pyriformes. truncatse, pedicellatse 5-7 x 5-6 mm., disco obliquo vel horizontal^ valvis 

 parvis. inelnsis. 



A large tree up to 180 feet high, up to 6 feet in diameter. Bark close, not ribbony (Robertson), of 

 the Peppermint type, branches usually smooth. Young branchlets compressed, but becoming terete with 

 age, usually of a reddish-brown colour or sometimes slightly pruinose. Leaves a pale slaty-green, usually 

 with reddish veins and veinlets. 



Juvenile leaves opposite for an indefinite number of pairs, narrow to broad-lanceolate, a few 

 oblong-lanceolate, acuminate, sessile to stem-clasping, a much darker green above than on the under surface! 

 invariahly drying a pale slaty-green colour, 1-5-10 cm. long, 9-30 mm. broad or broader; venation 

 moderately distinct, the median nerve very prominent beneath, usually of a reddish-brown colour and some- 

 what thickened at the base, very fine and channelled above ; lateral veins very fine, scarcely raised abov e 

 the surface of the lamina, radiating at an angle of 30-40° with the midrib, and with numerous fine secondary 

 veins; intramarginal vein usually distant from the edge. Oil dots very numerous, the larger ones less 

 numerous than the small ones. Internodes terete, glandular, reddish-brown. 



Intermediate leaves alternate, shortly petiolate, narrow to broad-lanceolate or falcate-lanceolate, 

 acuminate, oblique or rounded at the base, drying a pale slaty-green on both surfaces, 3-10 cm. long, 1-4 

 cm. broad; venation somewhat similar to that of the juvenile leaves; secondary veins diverging at an 

 angle of 30-40° with the midrib. 



Adnlt leaves alternate usually with slightly compressed petioles, 1-2-5 cm. long, narrow to broad, 

 lanceolate, obliquely-lanceolate and falcate-lanceolate, thin, drying a pale, slaty-green, 7-17 cm. long, 1-5-3 

 cm. broad; venation sometimes very distinct, the median nerve reddish-brown, slightly raised on both 

 surfaces towards the base, or sometimes faintly canaliculate above ; lateral veins numerous, diverging at 

 an angle of 20-30' with the midrib, usually much branched and unequal in length ; intramarginal vein very 

 irregnJar and sometimes well removed from the margin owing to the abbreviated lateral veins; oil-dots 

 conspicuous, veiy numerous. 



Inflorescence in axillary umbels, the peduncle compressed, supporting 9-21 small pedicellate 

 flowers. Buds clavatc to rostrate, glandular, slightly glaucous, including the usually filiform pedicel 

 6-9 mm. long, about 3 mm. in diameter. Calyx-tube funnel-shaped; operculum conical to rostrate or 

 acuminate, sometimes longer and broader than the calyx-tube. Anthers reniform with rather broad lateral 

 c ells and a fairly large terminal gland.
