DESCRIPTION. 



LXX. E. decipiens Endl. 



. (Synonym E. concolor Schauer, No. LXIX.) 



If my readers will turn to Journ. Roy. Soc. N.S.W., liv, Proc. Dec, 1920), there will 

 be found a brief note recording that I drew attention to the confusion that has gathered 

 around E. concolor in the same Journal, Vol. XLVII, p. 231 (1913). I have carried the 

 matter a stage further in the present work, Part XLII, page 66. I have now received 

 admirable specimens from Mr. C. A. Gardner, who is collecting on behalf of Mr. C. E. 

 Lane-Poole, the Conservator of Forests of Western Australia. His specimens come from 

 Spearwood, near Fremantle, Western Australia, are complete, and supply the missing 

 evidence that E. concolor is specifically identical with E. decipiens. 



At the top of p. 67 I suggested " it may turn out that E. concolor is the Fremantle 

 form of E. decipiens." Mr. Gardner's specimens prove this, and we are therefore justified 

 in suppressing E. concolor Schauer as a separate species. Not only has the conclusion 

 been arrived at by the direct evidence of field observations, but the result is confirmed 

 by seedlings raised from seeds from various localities, and grown in the Botanic Gardens, 

 Sydney. 



Mr. Gardner's description of the Fremantle tree, which follows, is valuable, 

 that while E. decipiens, it is E. concolor, and from practically the type locality. 



Eucalyptus decipiens Endl. — A tree attaining 30 to 50 feet, but usually muck less, the branches 

 spreading or almost pendulous, and very much like E. gomplwcephala DC. in appearance. Bark thick, 

 persistent and rough, of an ash-grey colour, the bark of the upper portions sometimes smooth. 



Leaves variable in shape and size. Sucker leaves opposite or alternate, obcordate or almost 

 orbicular, 2-3 cm. long and as broad, glaucous, the midrib scarcely conspicuous, the veins at an angle of 

 45 degrees to the midrib, the intramarginal one at a distance from the edge. Adult leaves ovate-lanceolate 

 or lanceolate, undulate, slightly falcate, coriaceous and shining, about 9 cm. long, the midrib conspicuous, 

 the intramarginal vein distinct and usually about -2 cm. from the edge. 



Peduncles lateral, terete and thick, - 8 cm. long, bearing a dense sessile head of 6 to 9 flowers. Calyx- 

 tube broadly turbinate, -5 cm. long and as broad. Operculum conical as long as the calyx-tube, obtuse, the 

 line of separation distinct. Stamens inflected in the bud, filaments white, filiform, terete or slightly 

 flattened at the base -7 cm. long, anthers globular. Ovary conical, style thickened at the base, about 

 •6 cm. long, tapering. 



Fruit broadly turbinate or campanulate -5 cm. long and about as broad. Capsule sunk beneath the 

 prominent truncate rim, the points of the valves slightly protruding. 



Collected at Spearwood near Fremantle in limestone on low hills near the sea. Some of the young 

 trees grow in dense patches, are erect, and might in appearance suggest a mallee. Coll. C. A. Gardner, 

 Hth September, 1920.
