Eucalyptus Tkozetiana, F.v.M. 
Thozet’s Gum. 
(Family M YRTACEvE.) 
Botanical description. —Genus, Eucalyptus. (See Part II, p. 33.) 
Botanical description. —Species, E. Tkozetiana , F.v.M., in “ Eucalyptographia ” 
(under E. gracilis), 1879. 
This affords another instance of a plant imperfectly described (“ Eucalypto- 
graphia”) being distributed in herbaria, and then, years after, being adequately 
described. Mr. It. T. Baker first described it adequately from complete material. 
Following are almost entirely bis words :— 
An erect, graceful tree, rarely attaining a height of over 70 feet. [The average height given to 
me by Mr. C. C. Chapman is about 30 feet, and Mueller quoted 60 feet.] 
Timber , brown or black brown, very hard. 
Bark, smooth, compact, whitish, decorticating in hard short flakes at the base (Mueller). 
Branchlets angular, but soon terete, reddish-coloured. 
Juvenile leaves linear or narrow lanceolate. 
Leaves mostly alternate, from lanceolate to oblong-lanceolate, under 6 inches long and half an 
inch wide, occasionally shining. Venation rather obscured in the thick epidermis ; lateral 
veins sparse, oblique, distant; intramarginal vein removed from the edge. Oil glands 
numerous, but exceedingly small. 
Floviers small on axillary peduncles or terminal panicles. Calyx turbinate, angled, gradually 
tapering into a short pedicel. Operculum conical, blunt. 
Fruits small, oval-urnshaped, angled, under 3 lines long, and under 1| lines in diameter, valves 
depressed. ( Proc. Linn. Soc. N.S.W., xxxi, 1906, 305.) 
Botanical Name. — Eucalyptus, already explained (see Part II, p. 34); 
Tkozetiana, in honour of Antli^lme Thozet (? 1826-1878), born in France, and a 
resident of Rockhampton, Queensland, for many years. He devoted the greater 
part of his life to the study of the cultivation and the economic products of Queens¬ 
land plants and of interesting and useful plants generally. His end was hastened 
through the botanical exploration of Expedition Range, west of Rockhampton, and 
this species was found on his last trip. For fuller particulars see my “ Records of 
Queensland botanists” in Proc. Austr. Assocn. for Aclv. of Science (Brisbane 
Meeting, 1909), xii, 382. 
Vernacular Names. — I have given the name “Thozet’s Gum” to this 
species. Mr. Baker proposes the name “Lignum Vitae” for it, but that name is 
already applied to two Eucalypts, and to one, if not two, species of Acacia.
