DESCRIPTION. 



LXXIV. E. Gillii, n. sp. 



Following is the description : — 



Frutex gregaria vel arbor parva, glauca, " Mallee " forinans. 



Lignum hepatieum, cortice glabro. 



Folia cordata, apice saepe acurninato ; circiter \\ inch (3 cm.) lata et 1 J inch (4- cm.) longa. 



Operculum longum, cupula in brevem pedicellum terniinans umbellis usque ad 8 plusve minusve in 

 capitulo, in uno peduneulo i inch. Antherse similes ad eas E. oleosce. 



Fructus similes ad eas E. oleosce varietatis glaucse. 



A gregarious, glaucous shrub or small tree forming a dense growth of Mallee, the timber red or 

 reddish-brown, and the bark smooth ; branchlets usually rounded. 



Juvenile leaves. — Not seen. 



Mature leaves. — Cordate, sessile or very short stalked, the base cordate, amplexicaul or rounded, 

 the apex often acuminate. Common dimensions are 1| inch broad and 1-^ inch long. Of uniform colour on 

 both sides. Midrib prominent, the lateral veins scarcely visible and penniveined, the intramarginal vein 

 not close to the edge. 



FlOwei'S. — The buds with calyx-tube slightly urceolate, particularly on drying, the operculum 

 rostrate, the shape of the bud resembling that of E. oloesa, var. glauca. The calyx-tube tapers into a short 

 pedicel, the heads of flowers up to 8 and more in number, on a common peduncle of half an inch. 

 Stamens inflected in the bud, the filaments pale yellow, the anthers similar to those of E. oleosa. 



Fruits similar to those of E. oleosa, var. glauca. 



I name it in honour of Mr. Walter Gill, Conservator of Forests, of South 

 Australia, from whom I originally received specimens of this form in 1900. 



Notes Supplementary to the Description. 



The colour of the leaves is always silver, or " blue" if you like, but "silver" seems better to me. It 

 seems very like your New South Wales Silver-leaved Stringybark, E. pulverulenta, in a general way, 

 though I am fully aware such a resemblance is purely superficial, — what I mean is that it seems to be our 

 South Australian silver-leaved tree just as that is yours. 



The only local name I could pick up was " Curly " Mallee, its curly or twisted growth making it 

 hard for stockmen to ride through it. (W. Gill.) 



The general height of the trees is about 20 feet, and the trunks aud limbs rather crooked. The 

 largest diameter of any of the trunks did not exceed 8 inches. (H. W. Garling, Broken Hill, N.S.W.) 



SYNONYMS. 



1. E. soeialis, F.v.M., var. laurifolia, F.v.M. 



2. E. laurifolia, Behr. Both in part. 



Under the original description of E. soeialis, F.v.M. (which is a narrow- 

 leaved form of E. oleosa, F.v.M., ante, p. 167), Mueller twice speaks of a broadish- 

 leaved form of it which he refers to E. laurifolia, Behr, which he suggests may he 

 a broad-leaved form of E. oleosa, F.v.M. This form does not strictly belong to 

 E. Gillii, but is the petiolate broad-lanceolate form which is intermediate between 

 E. oleosa and E. Gillii.
